Structure-Type Dimension

The LBCS structure-type dimension — every code from 1000 to 9999 for the type of building or structure on a parcel, with the full APA category descriptions.

Type of structure or building type on the land.

The structure-type dimension classifies the physical structure on the land — and, where there is no building, the constructed works that occupy it. Terms such as single-family house, office building, warehouse, hospital building, and highway all describe structural character, and they indicate the utility of the space independently of what is happening inside it.

Keeping structure separate from activity and function matters because buildings outlive their original purpose. A single-family residential structure used as a law office is still a single-family structure; it simply carries an office activity code and a legal-services function code alongside it.

Structure type is the dimension most closely tied to the built-environment attributes an assessor already records — stories, units, construction type — which makes it the easiest of the five to populate from existing county records.

Top-level categories

Every code in this dimension descends from one of these nine one-digit categories.

Code	Category
`1000`	Residential buildings
`2000`	Commercial buildings and other specialized structures
`3000`	Public assembly structures
`4000`	Institutional or community facilities
`5000`	Transportation-related facilities
`6000`	Utility and other nonbuilding structures
`7000`	Specialized military structures
`8000`	Sheds, farm buildings, or agricultural facilities
`9000`	No structure

How to read the code tables

The tables below list all 399 codes in the structure-type dimension, one section per top-level category. Indentation shows the hierarchy: a 1100 code is a subcategory of 1000, an 1110 code a subcategory of 1100, and an 1111 code a subcategory of 1110. Trailing zeros mark the level, so the number of significant digits tells you the depth of any code without looking it up.

A dash in the description column means the standard publishes the category name without an accompanying note.

1000 Residential buildings

Code	Category	Description
`1000`	Residential buildings	This is a catch-all category for all buildings built for residential purposes.
`1100`	Single-family buildings	Also includes any single-unit structure for habitation. The emphasis here is "single" and not "family." Includes split-level homes, linked group (houses that share foundations), manufactured homes, etc.
`1110`	Detached units	Standard single-family residential structures.
`1120`	Attached units	Usually two or more dwelling units side-by-side sharing one roof, but each unit has a separate front and rear access.
`1121`	Duplex structures	Generally a two-unit building that is divided horizontally, and each unit has a separate entrance from the outside or through a common vestibule. For semi-detached, double-duplexes, quadraplexes, maisonettes, etc., count the number of units in the structure and use the appropriate multifamily structure category. For applications that need to track the precise configuration, use additional fields or attributes in the land-use database.
`1122`	Zero lot line, row houses, etc.	This was a traditional planning category that is fast falling out of use. Many manufactured home developments are configured as zero lot line developments, townhouses are a form of zero lot line housing, and to further confuse the usage, former row houses are also used as barracks, group housing, or farm housing. Avoid this category if possible, but it is provided here for compatibility with many existing land-use databases that have this description.
`1130`	Accessory units	Use this category for an accessory unit, which is structurally separate and distinct from the main structure. An accessory unit is a second dwelling unit (structure-wise) that is added to an existing lot for use as a complete and independent facility. Note that not all accessory units have residential activities. For an accessory use (not structure) that is part of the main structure or not incidental to the primary use, classification options vary. Such a unit is also known as a "granny flat." See the working paper on Mixed Uses and Accessory Uses for a discussion of the full range of issues associated with accessory uses and their implications for land-use data classifications.
`1140`	Townhouses	A type of structure that has three or more separate dwelling units divided vertically, and each unit has separate entrances to a front and rear yard.
`1150`	Manufactured housing	Also commonly referred to as factory-built housing, which includes modular, mobile homes, and manufactured homes. The differences are subtle but, if a land-use application needs these finer gradations, create another attribute table to track the various kinds of factory-built housing. A manufactured home is a dwelling unit fabricated in an off-site manufacturing facility for installation or assembly at the building site, bearing a label certifying that it is built in compliance with the federal Manufactured Housing Construction and Safety Standard Act of 1974 (42 USC 5401, et. seq.), which became effective June 15,1976. A mobile home is a residential dwelling that was fabricated in an off-site manufacturing facility, designed to be a permanent residence, built prior to enactment of the Federal Manufactured Home Construction and Safety Standards. A modular home is a structure intended for residential use and is manufactured off site, but assembled on site. Note that not all modular homes are mobile homes. Then there are other related terms not related to structure type but to the overall site development character. Do not use this dimension for coding such compound land-use terms. They include (with a brief definition): Manufactured Home Development: A general category of development that includes manufactured home subdivisions and manufactured home communities (or land-lease communities). Manufactured Home Subdivision: A subdivision designed and/or intended for the sale of lots for siting manufactured homes. Manufactured Housing Community: Any piece of real property under single ownership or control for which the primary purpose is the placement of two or more manufactured homes for permanent residential dwellings and for the production of income. A manufactured housing community does not include real property used for the display and sale of manufactured units, nor does it include real property used for seasonal recreational purposes only, as opposed to year-round occupancy. Land-Lease Community: A residential development typified by single ownership of the land within the development, with the landowner retaining the rights of ownership. Home sites within the community are leased to individual homeowners, who retain customary leasehold rights. Manufactured Home Condominium (or cooperative): A condominium (or cooperative development) of manufactured homes.
`1200`	Multifamily structures	The following categories refer to the number of units and not by the number of floors or stories in the structure. For counting the number of households, have a separate field in the land-use database that lists the number of actual households in the building. For tracking the number of floors in a structure, use another attribute field. In short, this dimension is only for tracking the total number of units in a structure to get an indication of how big the structure is.

`1300`	Other specialized residential structures	For tracking the number of occupants, guest rooms, or beds, use additional attributes or fields in the land-use database.
`1310`	Barracks	Primarily associated with housing for uniformed services (police, military, etc.). For tracking number of occupants, guest rooms, or beds, use additional attributes or fields in the land-use database.
`1320`	Dormitories	Primarily associated with an institution that provides sleeping units and communal dining facilities. For tracking the number of occupants, guest rooms, or beds, use additional attributes or fields in the land-use database.
`1330`	Hotels, motels, and tourist courts	For tracking the number of occupants, guest rooms, or beds, use additional attributes or fields in the land-use database. Include country inns here although many also have residential facilities for the owner or caretaker. See the description for multifamily structure on how to account for household units.
`1340`	Single room occupancy units	Historically, many hotels and motels are converted to SROs. Even new SRO buildings are structurally no different from hotels. But many have small cooking facilities (independent or common) and other amenities not associated with a hotel. SROs may also have building code specifications different from hotels and motels. For tracking the number of occupants, guest rooms, or beds, use additional attributes or fields in the land-use database.
`1350`	Temporary structures, tents, etc. for shelter	For tracking the number of occupants, guest rooms, or beds, use additional attributes or fields in the land-use database.
`1360`	Other structurally converted buildings	This is a catch-all category for all other residential structure types that do not easily classify in any of the other residential categories. For tracking the number of occupants, guest rooms, or beds, use additional attributes or fields in the land-use database.

2000 Commercial buildings and other specialized structures

Code	Category	Description
`2000`	Commercial buildings and other specialized structures	Use this as a catch-all category when sufficient detail about structure types are not available (for example, when using remotely sensed data).
`2100`	Office or bank building	Buildings constructed for office-type uses. Typically these buildings constitute the majority of nonresidential structures in a community.
`2110`	Office building with drive-through facility	An office building with drive-in windows to serve customers in automobiles.
`2200`	Store or shop building	Most retail stores fall in this category. Use this as a catch-all category when sufficient detail about structure types are not available (for example, when using remotely sensed data).
`2210`	Shop or store building with drive-through facility	A building with drive-in windows to serve customers in automobiles.
`2220`	Restaurant building	Restaurant buildings that serve food for customers for consumption on or off premises. These structures may also be characterized by specialized cooking, serving, and health and hygiene equipment.
`2230`	Standalone store or shop building	A catch-all category for most commercial and retail business structures.
`2240`	Department store building	These buildings are characterized by large commercial spaces for retail or wholesale sales although they may be reconfigured for other uses. Use this category for urban and downtown department stores that look similar to office or standalone store, but have specialized building features (store fronts, display windows, large atriums, etc.).
`2250`	Warehouse discount store building	These structures are primarily warehouse in structural character, but also have other structural features convenient for large discount stores and "big-box retail" establishments.
`2260`	Market shops including open markets	Structures in this category include typical market shops and farmers markets with or without outdoor sales and service areas in single or groups of buildings with stalls for retail or wholesale commercial activities.
`2270`	Gasoline station	Structures that are specialized for selling gasoline with storage tanks, often underground or hidden. They may have bays for car washes. For convenience stores that sell gasoline, use the convenience store category.
`2280`	Automobile repair and service structures	Includes service garages and other structures that have bays for automobile service. These are specialized structures for auto repair and service.
`2300`	Office or store building with residence on top	Use this category for areas that the land-use database is not recording as multiple uses in a structure. Structurally, they may have some unique characteristics. Many planning applications in older neighborhoods can apply this category for large portions of their inventory.
`2400`	Office building over storefronts	This is a catch-all category to differentiate office buildings with street-level retail uses from a purely office building. Structurally, they are similar to a regular office building but vary in their treatment of street-level portion of the structure. Track the establishments in this type of structure by applying the appropriate code(s) from the function dimension.
`2500`	Malls, shopping centers, or collection of shops	Shopping center refers to a group of retail establishments that are located (and sometimes managed) as a single property. Most provide on-site parking, and their size and configuration reflect the kinds of merchandise and trade area characteristics. The two basic structure types are malls and open-air strip centers. Malls are enclosed and built in various shapes and sizes. Strip centers are a row of stores or service outlets managed as one retail entity that does not have enclosed walkways. Most have on-site parking in front of stores. Some may have covered canopies connecting store fronts. Typically the layout of stores are in a straight line, "U", or "L" shaped. They can take other configurations as well. For planning applications, knowing the type of shopping center (whether is serves the neighborhood or an entire region) is more useful than knowing the basic configuration. Land-use classification systems have used a variety of categories in the past. The basic system is divided into malls, shopping centers, and convenience stores. The type of merchandise (and services) offered is the primary factor differentiating types of malls, shopping centers, and convenience stores. Structure types vary widely within this class of commercial buildings and, because of the competitive nature of retailing and constant search for innovative merchandising, classifying every one of the structure types in this category may be difficult, if not impossible. This industry is probably the most in flux of all the categories planners encounter. Planners typically use four basic shopping center terms: neighborhood, community, regional, and superregional. These categories served planning functions for over a generation. Because of the significant changes in the industry since then, the International Council of Shopping Centers expanded the four basic categories to eight. The subcategories in this dimension reflect these new categories. The terms used in this category may be confused with similar terms in functional and activity dimensions. But the concepts are distinct: shopping center types are structures classified by their merchandise and trade area. In describing the subcategories of malls and shopping centers, size and area characteristics are provided, but they are intended to be used for illustrative purposes only in order to distinguish one type of shopping center from another. If your land-use data set needs to track size and area of malls and shopping centers, use the site area or building area attributes in the database for such details.
`2510`	Neighborhood center (convenience with one or more anchors)	Usually configured as a straight-line strip with no enclosed walkway or mall area; sometimes a canopy may connect the storefronts. Sizes vary from 30,000 to 150,000 square feet on sites ranging from 3 to 15 acres, and have a 3-mile primary trade area radius. Typically serves immediate neighborhood with convenience shopping. Often anchored by a supermarket or a drugstore, the center offers groceries, drugs, sundries, snacks, and personal services. Track the establishments in this type of structure by applying the appropriate code(s) from the function dimension.
`2520`	Community center (general merchandise with two or more anchors)	Usually configured as a strip (straight line, "U", or "L" shaped) center. Of all the varieties of shopping centers, these are by far the most common type and are configured in the widest range. Other terms used to describe this type are: discount centers (if anchored by a discount store), or off-price centers (if anchored by an off-price retailer). Sizes vary from 100,000 to 350,000 square feet on sites ranging from 10 to 40 acres, and have a 3- to 6-mile primary trade area radius. Serves a wider market than neighborhood and also offers wider range of goods, especially apparel and other "soft" goods. Anchors include supermarkets, super drugstores, and discount department stores. Some centers may also contain off-price retail stores selling toys, electronics, sporting goods, and home improvement and furnishings. Track the establishments in this type of structure by applying the appropriate code(s) from the function dimension.
`2530`	Regional center (enclosed mall with two or more anchors)	Usually configured as an enclosed mall with an inward orientation of the stores and have common walkways with parking areas around the perimeter of the building. Sizes vary from 400,000 to 800,000 square feet on sites ranging from 40 to 100 acres, and have a 5- to 15-mile primary trade area radius. Typically serves a region with general merchandise in full depth and variety. Apparel stores are usually the anchors. They may be traditional, mass merchant, or discount department variety. Track the establishments in this type of structure by applying the appropriate code(s) from the function dimension.
`2540`	Superregional center (similar to regional, but has three or more anchors)	Usually configured as an enclosed mall and may even have multiple levels. Sizes vary from 800,000 square feet and above on sites ranging from 60 to 120 acres, and have a 5- to 25-mile primary trade area radius. Typically serves the same purpose as a regional center, only with more anchors. Other terms used for this category include "super off-price malls" and "mega mall." Several anchors (three or more) offer more variety and depth of merchandise than a regional center. Track the establishments in this type of structure by applying the appropriate code(s) from the function dimension.
`2550`	Fashion/specialty center (higher end, fashion-oriented stores)	Usually configured as a mall, emphasizing rich decor and landscaping. Sizes vary from 80,000 to 250,000 square feet on sites ranging from 5 to 25 acres, and have a 5- to 15-mile primary trade area radius. Typically has upscale shopping. Also known as vertical market center. It need not have an anchor, but if it does, it is usually an apparel shop. Sometimes restaurants and entertainment play the anchor role. Other shops include boutiques and craft shops that offer unique merchandise of high quality and price. Track the establishments in this type of structure by applying the appropriate code(s) from the function dimension.
`2560`	Power center (category-dominated anchors with few small tenants)	Usually configured as a collection of several freestanding anchors and a few, if any, small tenants. Sizes vary from 250,000 to 600,000 square feet on sites ranging from 25 to 80 acres, and have a 5- to 10-mile primary trade area radius. Typically contains stores that offer the widest selection in a particular merchandise category at low prices. Also known as "category killers." Anchors include discount department stores, off-price stores, warehouse clubs, or other "category killers." Track the establishments in this type of structure by applying the appropriate code(s) from the function dimension.
`2570`	Theme or festival center (leisure, tourist-oriented, restaurants)	Mostly located in urban areas and sometimes adapted to historic buildings or other related urban activities nearby. They can also be one component of a large mixed-use project. Sizes vary from 80,000 to 250,000 square feet on sites ranging from 5 to 20 acres. They have no specific trade area. Primarily serves tourists or leisure market segments. They employ a unifying theme in design, layout, and sometimes even the merchandise they sell. Most often, they are anchored by restaurants and entertainment facilities. Track the establishments in this type of structure by applying the appropriate code(s) from the function dimension.
`2580`	Outlet or discount center (manufacturer outlet stores)	Strip configuration is the most common format, but others include malls and "village cluster." Many also have outdoor sales areas. Sizes vary from 50,000 to 400,000 square feet on sites ranging from 10 to 50 acres (some may be as big an 100 acres), and have a 25- to 75-mile primary trade area radius. Contains mostly manufacturers' outlet stores selling their own products at discounts. They are commonly found in rural areas and sometimes near tourist locations. Typically there is no anchor, but some stores may be larger than a typical anchor store and function like one to draw customers. Track the establishments in this type of structure by applying the appropriate code(s) from the function dimension.
`2590`	Other kinds of shopping centers	These categories are mainly for those applications that may want further differentiation. Track the establishments in this type of structure by applying the appropriate code(s) from the function dimension.
`2591`	Convenience stores or centers	Usually configured as a stand-alone store from the smallest size to a few thousand square feet of space. It is typically anchored by a mini-mart, gas station, or a 24-hour general store. Track the establishments in this type of structure by applying the appropriate code(s) from the function dimension. For gas stations, use the gasoline service station category.
`2592`	Home improvement center	Structurally, these centers are no different from other types of store buildings. Sometimes, they have outdoor sales or storage of merchandise. Sizes vary from a few hundred to several thousand square feet of enclosed space. Such a center is typically anchored by a hardware, furniture, carpet, or other store specializing in merchandise for home improvement. Track the establishments in this type of structure by applying the appropriate code(s) from the function dimension.
`2593`	Car care center	Structurally, they are similar to other store buildings, but some may include repair garages, car washes, and other similar automobile-specific construction. Typical functions include sales of auto parts, auto repairs, tires, and other auto-related merchandise. Track the establishments in this type of structure by applying the appropriate code(s) from the function dimension.
`2600`	Industrial buildings and structures	Use this as a catch-all category when sufficient detail about structure types are not available (for example, when using remotely sensed data). Because the subcategories mirror those used by industrial property appraisers, appraisal data sets may already contain some or all these distinctions.
`2610`	Light industrial structures and facilities	Many industrial structures were described by their roof design (saw tooth, monitor, etc.). But modern industrial structures may look no different from an office building.
`2611`	Loft building	Multistoried industrial building, often with higher ceilings and wider columns than a comparable office building. They are popular structures for rehab to residential activities. Other rehab adaptations include art galleries, selling books, computer data centers, mail order centers, and general office space.
`2612`	Mill-type factory structures	These are older single or multistory factories, common in many older industrial area, and supported by large wood beams and columns. They are popular structures for rehab to activities that are not industrial (art galleries, book selling, computer data centers, mail order centers, etc.). For lumber mills, see the agricultural facilities category.
`2613`	One-story modern manufacturing plants	Many newer industrial structures may look and generate impacts like a typical office building, but they rely on special power, water, or waste disposal systems for operations.
`2614`	Industrial parks	Also known as research and development parks, these are one or more buildings used for light industrial activities, often by several independent enterprises, that may share common loading, parking, and business services. Sometimes they are also referred to as business incubators that are similar to a light industrial structure but differ in the duration of tenancy (incubators only lease for a year to two to help a business in its initial development). Industrial malls, structurally, are like business incubators, but without tenancy restrictions.
`2615`	Laboratory or specialized industrial facility	A catch-all category for unique and specialized structures that cannot be easily classified under light industrial structures.
`2620`	Heavy industrial structures and facilities	Typically the largest facilities in a community, these structures house complex operations, some of which might be continuous (operated 24 hours a day, seven days a week). Because these facilities are constructed for specific occupants, they have a high degree of obsolescence. Because the subcategories mirror those used by industrial property appraisers, appraisal data sets may already contain some or all these distinctions.
`2621`	Assembly and construction-type plants	A typical heavy manufacturing facility.
`2622`	Process plants (metals, chemicals, etc.)	Process sometimes also applies to oil refineries, which are categorized separately.
`2630`	Oil refinery facility	Because these structures are of special concern for emergency management and other disaster recovery applications, they appear in a separate category with subcategories useful for emergency planners. Many state and federal emergency management applications (as described in the U.S. Federal Emergency Management Agency's HAZUS manual) specify these distinctions.
`2631`	Refinery with anchored equipment < 100,000 barrels/day	—
`2632`	Refinery with unanchored equipment < 100,000 barrels/day	—
`2633`	Refinery with anchored equipment > 100,000 barrels/day	—
`2634`	Refinery with unanchored equipment > 100,000 barrels/day	—
`2635`	Refinery pumping plant with anchored equipment	—
`2636`	Refinery pumping plant with unanchored equipment	—
`2700`	Warehouse or storage facility	Includes public storage, mini-warehouse, mini-storage, and other storage buildings.
`2710`	Mini-warehouse	—
`2720`	High-rise mini-warehouse	—
`2730`	Warehouse structure	Does not include grain elevator structures; they should be classified in agricultural structures.
`2740`	Produce warehouse	Specialized warehouse structures for storing, sorting, repackaging, and, sometimes, wholesale selling of produce.
`2750`	Refrigerated warehouse or cold storage	Large industrialized warehouse structures with specialized cold storage and climate control facilities.
`2760`	Large area distribution or transit warehouse	A subcategory for specifying large warehouse structures that occupy several acres of land.
`2770`	Wharf and dock shed	Waterfront structures for marine and water-based enterprises.
`2780`	Tank farms	Tanks that primarily store fuel, oil, and other liquid products (except water). Because these structures are of special concern for emergency management and other disaster recovery applications, they appear in a separate category with subcategories useful for emergency planners. Many state and federal emergency management applications (as described in the U.S. Federal Emergency Management Agency's HAZUS manual) specify these distinctions.
`2781`	Tank farms with anchored tanks	—
`2782`	Tank farms with unanchored tanks	—

3000 Public assembly structures

Code	Category	Description
`3000`	Public assembly structures	An essential category for many planning applications related to public safety, transportation, and emergency management. The subcategories give a broad variety of public assembly but, if your application needs more precision, create subcategories at the four-digit level under the appropriate broader category.
`3100`	Theater	Theaters are specialized structures for housing dramatic presentations, stage entertainments, motion-picture shows, and similar events that entail mass assembly of people. Most theaters have a stage or a screen for viewing. Some theaters may also have more than one stage for the same viewing area or have multiple screens (one on each wall of the auditorium). In any case, audience seating is oriented toward these viewing areas. Although theaters traditionally provided fixed seating on a gradually rising or stepped floor, modern innovations in audio and video technology may obviate such specialized constructions or the seating rows are flexible enough to be reconfigured as needed. Furthermore, other specialized viewing preferences (drive-in theaters, for example) do not have any unique structural characteristic beyond a traditional screen for viewing in an open parking lot. Despite these marked differences in structural characteristics of theaters, they all serve mass assembly of people for social, cultural, and entertainment events. Not included in this category are other specialized structures that are also commonly referred to as theaters. For example, operating theater (for conducting operations or surgical procedures) and theater of war (for war games and military exercises). Since such structures do not appear in isolation, i.e., are not standalone structures, they should instead be classified under the appropriate hospital or military structure category.
`3110`	Performance theater	Includes concert halls and other structures with fixed seats arranged on a sloped or stepped floor; may seat 300 to 3,000 people.
`3120`	Movie theater	A movie theater is a specialized theater for showing movies or motion pictures. The primary structural difference between a theater and a movie theater is the projection screen. However, many movie theaters can be easily adapted for stage performances and many stages have folding screens for movie projections. Although screen shapes are mostly rectangular, they come in a variety of shapes. Also, some special-purpose multimedia movie theaters use multiple screens (one on each wall face) or the entire ceiling surface, which are sometimes curved or geodesic in shape. Other terms used to describe these structures include talkies, cinema theaters, and motion pictures. This category also includes cineplexes — complex structures with multiple movie theaters, each theater capable of providing performances independent of the others in the complex. Structurally, theaters in a cineplex are grouped in a manner that allows them to share box or ticket offices, parking facilities, lobby areas, restrooms, concession stands, signs and marquee displays, and other service and maintenance facilities. These structures first started appearing in shopping centers and malls, sometimes integrated with the layout of the mall. Historically, a cineplex meant a theater complex with two or more movie theaters. Popular configurations have nine or twelve theaters. But as structures evolved to accommodate twenty or more theaters, the movie-theater industry started using such terms as multiplex, megaplex, and mega theater to differentiate these newer configurations from older cineplex layout. But there is no clear structural distinction between a cineplex and a megaplex. The distinction between a cineplex and a megaplex has been further blurred because developers sometimes retrofit cineplexes with more screens, often smaller, within the existing structure.
`3130`	Amphitheater	Some can accommodate 15,000 to 20,000 spectators. Modern versions have fixed seating (about 40% of capacity) under a roof (but no walls) and the remaining spectators spread out on sloping lawns. They are very popular for summer music concerts.
`3140`	Drive-in theaters	—
`3200`	Indoor games facility	Many bowling alleys, golf ranges, skating rinks, etc., do not have large spectator seating areas but cater to a large number of people playing in the facility. If necessary, create subcategories here for to differentiate between structures (skating rinks from golf ranges, for example).
`3300`	Sports stadium or arena	Structurally, the main distinction between a stadium and an arena is its size. Stadiums are larger than arenas and seat 40,000 to more than 100,000 spectators; arenas typically seat 8,000 to 22,000. The layout of seating and sight lines in stadiums follow a fixed sport (baseball or football), whereas arenas are designed around the flat, central space whose size is about the size of a basketball court. Arenas also host circuses, ice shows, indoor soccer, hockey games, horse shows, and music concerts. Increasingly, many stadiums, especially domed facilities, are serving arena-like events. Special event stadiums are the kind built for a single purpose or event (tennis, motor speedways, horse race tracks, velodromes, etc.). Another common term for this category is coliseum. Note that the name of a facility may have the word coliseum in it but may in fact be a multipurpose structure (as described in the next category). Similarly, another confusing term is a facility with the name "civic center." It may refer to an arena, city hall, auditorium, or, sometimes, even a jail.
`3400`	Exhibition, convention, or conference structure	A typical exhibition hall facility occupies several city blocks and contains 50,000 to 700,000 square feet of contiguous flat floor space. These halls have high ceilings (25 to 35 feet) and can accommodate a variety of events. Some very large cities (Chicago, for example) have multilevel exhibition halls. Convention structures have both an exhibition hall and a number of meeting rooms. Many also have kitchen and banquet facilities, and an auditorium for special events. Trade shows, public shows, conventions, food functions, receptions, dances, banquets, assemblies, and other activities are typically hosted in these structures. Multipurpose structures have combinations of exhibition, convention, and arena facilities. Some of these may be co-located or created out of a single enclosed space that is reconfigured. This category also includes the horseshoe-shaped auditorium buildings popular in the 1930s and 1940s in many midsize to big cities. These structures have a fixed stage at one end of a flat floor area on which were portable seats on risers and fixed seats on other levels. Multipurpose arenas have since replaced these kinds of structures. Trade centers are not included here. They are usually a special-purpose office building for a specific group of enterprises (brokers, importers, freight forwarders, etc.). These structures belong in the office building category. Merchandise marts also serve the same purpose as trade centers but also have permanent exhibit space (30,000 to 50,000 square feet) with lower ceilings than exhibition halls. These structures serve specific consumer-oriented industries (gifts, apparel, furniture, floor coverings, computers, etc.). Because many cities do not have such facilities, these trade groups often use existing exhibition and convention facilities. In Europe, exhibition hall facilities are also known as congress centers.
`3500`	Churches, synagogues, temples, mosques, etc.	These are specialized religious structures that have pulpits, choirs, musical instruments, such as organs, pianos, and bands, besides large seating areas. Some churches, mosques, temples and other similar religious structures may also have towers (bell towers in churches, minars in mosques, or pagodas in temples). Many religious structures also have classrooms (for Sunday school activities) and residential quarters for one or two families. But the structures are primarily designed for worship and religious congregations. Some modern wedding chapels and structures that accommodate a wide range of religious or social activities are also included here. Architecturally, church buildings have been known as either a schoolhouse, modern, traditional, courthouse, utility, or storefront churches. Except for the storefront variety, all these structures belong in this category. If an application needs to differentiate, use the definitions below to create subcategories. Schoolhouse churches look like one-room schoolhouses, typically frame-built in a rectangular shape with a double row of pews to define the cruciform aisle, and the pulpit centered at the head of the main aisle. Modern churches refer to the explosion of innovative church forms popular with designers after World War II. They take many shapes and sizes with visually striking features (large entrances, long masonry spires, etc.). Traditional churches refer to the standard rectangular plan with steep roof pitches, masonry built, and sometimes having tall bell towers or steeples. Courthouse churches reflect the 1875-1925 American municipal architecture of urban centers. These centers often included the town bank, city hall, post office, and other public uses along with a church building designed to look like the courthouse. Utility churches are buildings with low roofs, often constructed of concrete blocks, sometimes with vinyl sidings, and pointed or spiked steeples, if any. They primarily serve small independent denominations. Not included in this category: Storefront churches refer to a store or a similar structure not typically used for religious activities that is now used as a meeting place for a congregation. Structures adapted for congregations include barns, stores, warehouses, old public buildings, and single-family houses. The structure dimension should classify such structures in the appropriate structure category. Use the activity dimension to specify the religious congregation activities and the function dimension to identify the religious establishment. Megachurches are mostly large structures that can seat several thousand people and have a variety of amenities and host a wide range of activities. The main structure has a stage with a pulpit with arena-style seating. It may also include facilities for teaching, broadcasting, entertaining, and selling gifts, books, and other paraphernalia. They may also include a chapel for weddings and funerals. The architecture and interior design evoke a convention or civic center design and also generate similar traffic and impacts. Such structures should be classified under exhibition and convention center category. Any other facility that has been converted for religious events and congregations (houses, office buildings, community centers, etc.)
`3600`	Capitol buildings	Structures specialized for assembly of elected and other public officials to conduct public discourse. Although the main enclosure is similar to many stepped or raised floor plans of theaters and auditoriums, the overall structural characteristics of a capitol building includes other structures and facilities associated with office-type activities.
`3700`	Covered or partially covered atriums and public enclosures	Often found in downtown locations that provide shelter for large public gatherings and communal activities.
`3800`	Other community structures	This is a catch-all category for all other mass assembly structures, including community halls, reception halls, wedding halls, etc.
`3900`	Passenger assembly	—
`3910`	Mixed mode terminal	—
`3920`	Airport terminal	—
`3930`	Bus terminal	—
`3940`	Train station	Create subcategories if applications require specific train station type (long distance versus transit). But many long distance stations also serve transit and local trains.
`3950`	Harbor or port terminal	—

4000 Institutional or community facilities

Code	Category	Description
`4000`	Institutional or community facilities	Use this as a catch-all category when sufficient detail about structure types are not available (for example, when using remotely sensed data).
`4100`	Medical facility	—
`4110`	Hospital building	—
`4120`	Medical clinic building	—
`4200`	School or university buildings	—

`4440`	Outdoor facility, no major structure	—
`4450`	Zoological parks	Besides the normal viewing and tourist areas, zoos may also have special structures and enclosures for various zoological and botanical habitats. They also have extensive veterinary and animal services along with associated administration buildings. When a zoo is part of a larger park, for example, a state park, use the appropriate site dimension category to identify such land-use characteristics.
`4500`	Public safety-related facility	—
`4510`	Fire and rescue station	—
`4520`	Police station	—
`4530`	Emergency operation center	—
`4600`	Jails, penitentiaries, detention centers, and other correctional facilities	—
`4700`	Cemetery, monument, tombstone, or mausoleum	The three traditional cemetery types are: the monument cemetery, the lawn cemetery, and the garden memorial park. Each is a distinct facility type, although it may appear that the main difference is in the way the site is developed. The monument cemetery, which evolved from ancient churchyard burial grounds, has stone memorials. The lawn cemetery, features lawns with extensive landscaping and looks like a park, and the memorials are sometimes bronze. They evolved from a need to have wide public acceptance for new cemeteries. The garden memorial park is a logical extension of the lawn cemetery with elaborate sculptures and architectural features that counter the monotonous lawns and memorials. Memorials in all types of cemeteries vary from a simple tombstone to elaborate mausoleums. Many plans recognize the open space quality of cemeteries by placing jogging and bike trails adjacent to such areas. Also, some cemeteries have allowed other recreational uses on unplotted parts of the property. Classify or capture such uses of a cemetery in the activity dimension.
`4800`	Funeral homes and cremation facilities	Land-use plans traditionally treated such facilities as serving a community function. Even though many funeral homes now are for-profit enterprises, for lack of a more suitable category, this facility type remains in the community facility category. Many funeral homes may look like large older-style single-family residential structures but have significant structural differences to accommodate funeral functions. They often contain one or more assembly rooms that can hold 25 to 400 people, several smaller rooms for embalming, caskets, showing, and other functions, and because the funeral plant is a 24-hour operation, they often have sleeping quarters for a family.

Code	Category	Description
`5000`	Transportation-related facilities	—
`5100`	Linear or network feature	Many local land-use databases do not have parcel IDs for road segments, including rights-of-way. A typical community may have as much as 15% of its total land consumed by such linear features. Tracking the total amount of land consumed by such facilities is becoming increasingly critical for answering many planning applications. Even in cases where GIS-based maps ignore roads as a category when mapping, the underlying geometry has polygons assigned to the rights-of-way. This category is a way to assign a structure type for such polygons in the GIS, or for parcels that are road segments in the database. See the LBCS web site for further details about this issue.
`5110`	Pedestrian trail, sidewalks, etc.	—
`5120`	Bicycle and other nonmotorized paths	—
`5130`	Highways and roads	The subcategories provided for roads follow the Federal Highway Administration's (FHWA) functional road classification scheme. This scheme explains to Metropolitan Planning Organizations how they can meet specific reporting requirements of the Intermodal Surface Transportation Efficiency Act of 1991. Many local and state agencies use the same categories for their local planning applications. The two additional subcategories, local and alley, provided below can capture some additional local road types. Local roads may be private or unfunded roads. Alleys are commonly used in denser urban areas. There is no color scheme for roads in most local planning applications; they are left white or colored black. Depending on the scale of the map (regional or statewide maps), roads are may be shown as dark (usually black) lines. But ISTEA reporting requirements specify the following scheme for regional or statewide maps: Interstate highways - Blue solid line Other Freeways and expressways - Brown solid line Other principal arterials - Red solid line Minor arterials - Green solid line Major collectors - Purple solid line Minor collectors - Yellow solid line All future routes classified should be shown as dashed lines using the appropriate color. At this scale where roads are depicted as lines, local roads and alleys may be too small to register on a map, but if they do, use black dashed lines.

`5140`	Highway bridges and tunnels	Because these structures are of special concern for emergency management and other disaster recovery applications, they appear in a separate category useful for emergency planners. Many state and federal emergency management applications (as described in the U.S. Federal Emergency Management Agency's HAZUS manual) specify this distinction. This category may be applicable when individual segments of roads are classified. For many local land-use applications, this linear facility (along with the right-of-way) may appear as a road segment. As local databases improve their accuracy, this category will increasingly become significant.

`6320`	Landfill facility	Area fill and trench fill are two commonly known facility types. The area method is employed to fill a depleted quarry pit, a canyon, or a natural depression. After a day's worth of dumping, heavy tractors compact the solid wastes evenly, and cover the layer with dirt or other inert solid wastes. In canyon-type landfills, cover materials may come from scraping the walls. The final grade of such landfills is made even with the surrounding topography. In the trench fill method, dump trucks deposit waste in trenches dug out for this purpose. Heavy bulldozers in the trench compact and even the surface. At day's end, the bulldozers use dirt from the excavated material to cover the surface. Heavy front-end loaders, scrapers, and other equipment are used for digging trenches. When this type of landfill is completed, its grade is usually higher than the original grade. Because landfills try to keep the working surface as small as possible, they may not be visible in aerial pictures. Landfills are also synonymous with resource recovery facilities where some of the waste products are separated for recycling or additional treatment.
`6330`	Incinerator, composting, or similar facility	Mainly industrial in character, these facilities may sometimes be co-located with landfills and other solid waste operations.
`6340`	Hazardous waste storage facility	This single category should serve most planning applications. However, communities that have a variety of hazardous waste facilities and want to further delineate such facilities may do so by using the subcategories. But for the rest, this one category should suffice. All emergency preparedness plans require inventory of such facilities, and common applications include local traffic routing rules.
`6341`	High-level waste facility	These facilities handle the most hazardous of all waste products — fission products, which have high-intensity and penetrating radioactivity. The processes involved are heavily mechanized because humans cannot come into contact with these such materials.
`6342`	Transuranic waste facility	These facilities mainly bury the radioactive materials because they decay longer (half-life may be several thousand years) than the fission type. Equipment and structures reflect mining and large-scale industrial operations.
`6343`	Spent fuel facility	Normally these are co-located with nuclear reactor facilities and contain large water pools to store spent fuel. Such fuel is considered high-level waste, but many former nuclear reactor sites still function as spent-fuel facilities until the fuel can be disposed.
`6344`	Low-level waste facility	Such facilities collect, store, and process low-level radiation waste from industrial, commercial, and institutional sources. Their primary operation is to reduce the volume of radioactive material though filtration, evaporation, incineration, and compaction. The transportation and movement of wastes to these facilities are regulated and adequate emergency preparedness includes risks of pollution from such facilities.
`6350`	Sewer treatment plant	Because these structures are of special concern for emergency management and other disaster recovery applications, they appear in a separate category with subcategories useful for emergency planners. Many state and federal emergency management applications (as described in the U.S. Federal Emergency Management Agency's HAZUS manual) specify these distinctions.

7000 Specialized military structures

Code	Category	Description
`7000`	Specialized military structures	These are broad categories for military and defense establishments. It is a complex category that may include other structure types. Local planning applications are only concerned about this at a broad level, but base planners may want to add additional subcategories for some specialized operations, as shown for naval facilities. However, for normal land-use inventories necessary for base planning, apply categories other than "military installation" from this structure-type dimension. In combination with coding from the activity dimension, base planners can filter a variety of land-use characteristics suitable for base planning.
`7100`	Joint services facility	—
`7200`	Air Force facility	—

8000 Sheds, farm buildings, or agricultural facilities

Code	Category	Description
`8000`	Sheds, farm buildings, or agricultural facilities	Use this category for all agricultural structures. For tracking specialized farm and agricultural structures, use the subcategories. This broad category also includes lumber mills, maple sugaring facilities (sugar camp, sugar bush, etc.), agricultural terraces (to hold water and allow infiltration), waterways and stabilized paths (to direct runoff), sediment basins (to hold silt), and fencing (mainly to reduce livestock density).

`8200`	Livestock facility	This is a catch-all category for all livestock-related structures that serve horses, cattle, sheep, etc.
`8210`	Dairy facility	Includes barns, milking barns, milking parlors, etc.
`8220`	Poultry facility	Includes poultry houses for chickens, broilers, layer hens, etc.
`8230`	Cattle facility	—
`8240`	Stables and other equine-related facilities	Includes horse trot-tracks, and other horse training or veterinary facilities for horses.
`8300`	Animal feed operations facility	Although they may be integrated into a livestock facility, some are separately located.
`8310`	Confined feedlot facility	Although confined feedlots often refer to feeding operations for hogs, the agriculture industry has had a history of confined feedlot operations for a number of decades. Poultry feedlots, for example, have been confined for many years. Another term that is synonymous but with a different meaning is the US EPA and USDA definition for concentrated animal feeding operations (CAFO). This definition refers to feedlots greater than a certain capacity, in this case 1000 animal units. An animal unit is defined as the equivalent of one beef cow. Although definitions vary in zoning and other local regulations, the trend is to have some measurement unit based on impacts of effluent. Using this measure, a CAFO is any facility serving more than 1,000 cattle or 2,500 hogs or 55,000 turkeys, etc. The CAFO definition has other equivalents for other livestock types. If CAFOs have to be measured separate from confined feedlot facilities (i.e., that includes facilities with less than 1,000 animal units), create another subcategory or a special field to keep track of the CAFO units.
`8400`	Animal waste-handling facility	—
`8410`	In ground silos	Normally they may not be visible, but newer facilities have air vents and other gas recycling equipment co-located.
`8420`	Waste lagoons	These are open pits and low-lying areas where animal waste is drained from a feedlot or a confined facility. Although fast disappearing, some of these still do exist and the terms used to describe them vary.
`8430`	Concrete storage units, covered	Unlike other types of animal waste-handling facilities, these are more portable.
`8440`	Concrete storage units, uncovered	Unlike other types of animal waste-handling facilities, these are more portable.
`8450`	Composting facility	When such structures are part of a combined animal-waste handling facilities, use the higher-level Animal waste-handling facility category.
`8500`	Greenhouses	Rarely, but, also known as glasshouses, these are enclosed structures with or without climate control facilities for growing plants and vegetation under controlled environments.
`8600`	Hatcheries	—
`8700`	Kennels and other canine-related facilities	—
`8800`	Apiary and other related structures	This is a catch-all category all specialized structures and facilities, such as the following: apiary, which is a bee house or a place where beehives are stored; dovecote, a pigeon or doves house that is usually set above ground; a duckhouse (for ducks), falconry, a facility for housing, training, and breeding birds of prey; etc.
`8900`	Other farm and farming-related structures	Farm-related structures include barns and others, such as: ash house, a farm building to store ash or fertilizers; backhouse, a brewing house attached to a farm or farming structure; bark house, a farm building to store barks of trees; hay barns and chaff houses for storing hay and animal feed; boiling house, a structure where animal feed is prepared; chitting house, a shed to germinate and grow potatoes; laithe, a cow-house with crop storage space; hemmel, a shelter for farm animals with no stalls; etc.

9000 No structure

Code	Category	Description
`9000`	No structure	—
`9100`	Not applicable to this dimension	Use this code as a permanent code for those records that will never be classified in this dimension. It is normal for land-use databases to have records that may never be classified and left blank instead. But LBCS recommends that all records have a code because some computer applications may not be able handle blank entries (null values in database terminology).
`9200`	Unclassifiable structure	Use this category as a temporary placeholder for activities that cannot be grouped anywhere until the classification scheme is updated. Check the before revising the classification scheme.
`9300`	Subsurface structures	Use this category for activities that occur below the surface that are of no interest to the applications that will use this data set. Assigning one of the unknown categories may be inappropriate.
`9900`	To be determined	Use this code as a placeholder until an appropriate code can be assigned. It is normal for land-use databases to have records that may never be classified and left blank instead. But LBCS recommends that all records have a code because some computer applications may not be able handle blank entries (null values in database terminology). This code could also be used as the default value for data-entry work. The subcategories serve the same purpose for other coding levels.
`9990`	To be determined	—
`9999`	To be determined	—

Notes on applying these codes

Where a parcel carries multiple buildings, code the principal structure. Accessory buildings are normally captured either as additional records or as secondary codes, depending on the data model.
Parcels with no structure at all are coded 9000 (no structure); what is on such a parcel is described in the site development character dimension.
