183:(FAR) typically describes non-residential development, based on the ratio of building floor space to land area, both using the same unit of measure. Additional analysis might estimate the number of buildings or building coverage based on the number of dwelling units per building, the number of stories and/or the building size in square feet.

assumptions about density to the available land area. The build-out calculation may deduct land due to physical constraints to development (e.g. sensitive natural resources), potential infrastructure dedications (e.g. streets, public open space, or stormwater management structures), and practical

Potential impacts can be derived from build-out by multiplying the amount of development by various factors (e.g. calculating the number of new school children, traffic trips and water demand). Note: the multipliers frequently vary by land use type. These figures only provide the raw demand for

density is most often expressed as residential dwelling units per acre (DU/ac), but a minimum lot size is also used (especially in zoning). (Note: outside the United States, the metric system usually uses hectares as the area unit of measurement). A

or allocation adds demand factors such as economic growth and the land’s relative attractiveness for new development. Land developers perform build-out calculations to assess the profitability of a parcel of land.
220:
Existing structures will limit the number of additional new dwelling units allowed on the land. If an existing subdivision contains 6 dwelling units, the available capacity is 34 units.

Performing a build-out analysis identifies the holding capacity of the land. The build-out calculation provides the supply of development for forecasting future land use growth.
