The HCA, enacted in 2019 as Senate Bill (SB) 330, declared a statewide crisis in order to address California’s affordable housing shortage, strengthen tenant protections and preserve existing affordable housing. The HCA has been in effect since January 1, 2020, with subsequent updates and clarifications made through SB 8 (2021) and AB 1218 (2023).
Locally, in an effort to balance housing production and housing preservation, the Los Angeles City Council adopted the RPO in early 2025. The RPO codifies the HCA, making provisions that apply to housing development projects permanent. It also expands occupant protections and enhances requirements for Affordable units in the City.
