The City originally adopted its Affordable Housing Set-Aside (AHSA) Ordinance in 1990 to address a shortage of affordable housing available to moderate, low, and very low-income households. In 2014, the AHSA ordinance was revised and renamed the Affordable Housing Program (AHP).
The AHP Ordinance covers both for-sale and rental housing projects. It requires a set-aside of Below Market Rate (BMR) units in new ownership housing developments of 10 or more units and an impact fee on all new rental housing projects or in-lieu BMR unit production. In addition, the Planning Regulations include a “Development Bonus Program” which increases allowable height, Floor Area Ratio (FAR) and/or density in exchange for affordable housing units and community benefits. The program was in part designed to counter the “Palmer Decision” (Palmer/Sixth Street Properties, L.P. v. City of Los Angeles, 2009) that prevented cities from mandating affordable housing in new rental projects.
Assembly Bill 1505 (AB1505) passed in 2017 in response to the Palmer Decision which restored local governments’ ability to require developers to include affordable rental units in their projects. The City is now allowed to revise the AHP by adopting inclusionary housing requirements for rental developments under the authority granted by AB 1505, also known as the “Palmer Fix”.
On July 15th, 2025, the City contracted with Economic and Planning Systems, Inc to conduct this study in conjunction with the update of the Development Impact Fee. This work is expected to take a year and a half to complete.
