Senate Bill No.9

What is SB-9?

Senate Bill No.9, among other things, requires local agencies to ministerially approve no more than two residential units within a single-family residential zone and a parcel map for an urban lot split that meets certain requirements. As of January 1, 2022, new state laws supersede local ordinances.

Changes in State Law

Due to the housing shortage in California, the State Legislature has passed significant housing-related laws in the past few years. Updates to State Law expands areas and conditions under which parcels may be subdivided and additional housing may be allowed. Danville Resolution 85-2021 (PDF), approved by the Town Council, and SB-9 FAQs (PDF) both reflect the regulations permitted by new state law, effective January 1, 2022. Be advised that the information is subject to change, as state guidelines and interpretations are typically issued after the enactment of the new law.
