AB 2433: Housing development: density bonus.

Official summary

Legislative Counsel’s Digest (official, as of the latest version). Written by nonpartisan legislative staff; reproduced verbatim.

(1)Existing law, commonly referred to as the Density Bonus Law, requires a city or county to grant a density bonus, other incentives or concessions, and waivers or reductions of development standards, as specified, to an applicant for a housing development when the applicant seeks a density bonus for the housing development, as specified, if the applicant agrees to construct, among other things, a specified percentage of units for very low income, lower income, or senior citizen housing, and meets other requirements.

This bill would, instead, require a city or county to grant a density bonus, other incentives or concessions, and waivers or reductions of development standards, as specified, to an applicant for a housing development when the applicant submits an application for a housing development that a city, county, or city and county determines meets specified criteria, including, among others, the housing development includes specified percentage of units for very low income, lower income, or senior citizen housing.

(2)Existing law defines density bonus for the purposes of the Density Bonus Law to mean a density increase over the otherwise base density, as specified. Existing law specifies the base density calculation standards and requires base density to be determined using dwelling units per acre, except as otherwise provided. For the purpose of calculating a density bonus, existing law requires the residential units to be on contiguous sites that are the subject of one development application, as specified. Existing law also requires the density bonus to be permitted in geographic areas of the housing development other than the areas where the units for the lower income households are located.

This bill would allow an applicant who provides a base density study, as defined, to elect to receive a density bonus in the form of a percentage increase in maximum floor area ratio, as specified. The bill would create an additional exception to the requirement that base density be determined using dwelling units per acre for applicants who elect to provide a base density study.

This bill would revise and recast the provisions related to permitting of a density bonus relative to the geographic area to instead require a density bonus, incentive, or concession, or waiver or reduction, on sites that are the subject of the same housing development, as specified.

(3)Existing law requires a city or county to adopt procedures and timelines for processing a density bonus application and to notify the applicant for a density bonus whether the application is complete in a manner consistent with specified timelines.
