Affordable Housing Preservation Ordinance


Affordable housing preservation seeks to maintain the supply of lower-cost housing to avoid displacement of tenants or the loss of affordable units due to new development. The Board of Supervisors initiated an ordinance to preserve existing affordable housing that considers a variety of strategies, such as the regulation of condominium conversions and mobile home park closures, and one-for-one replacement or “no net loss” policies.

Please note the Governor’s Executive order modifying some noticing requirements related to the California Environmental Quality Act (CEQA).

We welcome your comments on the Public Hearing Draft. Please send your comments to the Housing Policy Section at housing@planning.lacounty.gov.


In September 2019, staff developed a Preliminary Affordable Housing Preservation Ordinance Policy Outline, which introduced policies for stakeholder discussion related to no net loss, right to purchase (for condominium conversions), and mobilehome park preservation.

In June 2020, staff developed a Draft Policy Summary and Preliminary Draft Ordinance based on stakeholder discussions and studies (see “Studies” below).


The Affordable Housing Preservation Ordinance is supported by a nexus study and feasibility analysis for an affordable housing replacement fee, as well as a land use policy study for mobilehome parks.

The Affordable Housing Replacement Nexus Fee & Feasibility Study calculates the maximum fee that can be charged to a developer who must replace housing affordable to lower-income households but does not construct the affordable unit(s). The study then models the feasibility of replacement in six submarkets under different development scenarios (renovation, condominium conversion, and demolition/new construction).

The Mobilehome Park Land Use Policy Study includes a set of policy recommendations for near- and long-term consideration, based on best practices among California jurisdictions for the preservation of mobile home parks as naturally occurring affordable housing.
