California Senate Bill 9 (SB9)

Senate Bill 9 (SB9), also referred to as the California HOME (Housing Opportunity and More Efficiency) Act, was signed by Governor Newsom on September 16, 2021. This bill amends Section 66452.6 of, and adds Sections 65852.21 and 66411.7 to, the Government Code, relating to a streamlined housing development process. SB9 would require a proposed housing development containing no more than two residential units within a single-family residential zone to be considered ministerially, without discretionary review or hearing, if the proposed housing development meets certain requirements. 

Section 10.05.3500 et seq of the City's Municipal Code incorporates the provisions of Senate Bill 9 "Urban Lot Splits."

What is SB9?

The bill mandates local jurisdictions, such as the City of Millbrae, to ministerially approve two-unit dwellings and a subdivision of one lot into two (urban lot split) in any single-unit dwelling zone. SB 9 became effective on January 1, 2022.
