Los Angeles's zoning regulations are published in Chapter 1 of the Municipal Code, commonly known as the Zoning Code. The City's zoning provisions regulate many aspects of how land may be used―everything from specifying where different uses may be located to outlining the processes for requesting relief from certain land use regulations.
In Los Angeles, similar land uses are grouped into general categories and referenced by a letter in the alphabet. This letter is followed by a number to signify the allowable intensity of the use or, in some cases, the density.
Zoning also establishes limitations on the size and scale of buildings through the use of height districts. The height district limits the height of a building and its square footage. The height district is defined by a number, which appears after the zone class.
From time to time, properties may be subject to further development limitations—land use restrictions that prevent construction of a building at the maximum height or mass. These properties have a prefix or an additional suffix attached to the height district.
In a city as large as Los Angeles, some neighborhoods are subject to tailored zoning regulations―an overlay, which functions as an additional layer of zoning rules. Properties located within an overlay are typically identified by a series of letters at the end of the zoning string but may also be identified by a unique zone.
