Appendix C: Preliminary Application (Senate Bill 330, Statutes of 2019)

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

The Housing Crisis Act of 2019 (Chapter 654, Statutes of 2019 (SB 330)) strengthens protections for housing development projects under the Housing Accountability Act (HAA), Planning and Zoning Law, and the Permit Streamlining Act. The provisions set forth under SB 330 sunset in 2025.

Among other provisions, to increase transparency and certainty early in the development application process, SB 330 allows a housing developer the option of submitting a “preliminary application” for any housing development project. Submittal of a preliminary application allows a developer to provide a specific subset of information on the proposed housing development before providing the complete information required by the local government. Upon submittal of an application and a payment of the permit processing fee, a housing developer is allowed to “freeze” the applicable standards to their project early while they assemble the rest of the material necessary for a full application submittal. This ensures development requirements do not change during this time, adding costs to a project due to potential redesigns due to changing local standards.
