Senate Bill 9

Senate Bill 9 was signed by Governor Newsom on September 16, 2021 and becomes effective January 1, 2022. This bill 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.
