Housing Development Project Definition

Housing Accountability Act Technical Assistance Advisory · 2026 edition · updated 2026-09-25 · California

Government Code, § 65589.5, subdivision (h)(2).

A “housing development project” means a use consisting of residential units only, mixed use developments consisting of residential and non-residential uses with at least two-thirds of the square footage designated for residential use, or transitional or supportive housing. Because the term “units” is plural, a development must consist of more than one unit to qualify under the HAA. The development can consist of attached or detached units and may occupy more than one parcel, so long as the development is included in the same development application.
