Here’s a brief explanation directly from LA Planning Dept communications, with a link to the current draft. Basically this is a set of City of LA Ordinance updates so the City planning laws line up more directly with State laws recently passed. For more tutorial information from Planning, here are links to an April 2024 Webinar YouTube recording (in English) and the presentation slide deck from that meeting.

About the Draft Housing Element Sites and Minimum Density Ordinance (CPC-2024-387-CA)

The Housing Element Sites and Minimum Density Ordinance is intended to enact state housing element law for different types of sites related to the most recent Housing Element of the General Plan. In particular, it addresses housing element law requirements around housing replacement, no net loss, by-right development for 20% affordable housing projects, and minimum densities. The various requirements apply to three different kinds of Housing Element Sites, including the Inventory of Sites, sites located on Prior Inventory of Sites, and Lower Income Rezoning Sites. In addition, the draft ordinance would add minimum density requirements to various multifamily zone classifications to facilitate the implementation of state law as well as ensure new development in these areas complies with policy objectives.
