California YIMBY: SB 423 permanently extends the provisions of SB 35, and expands them to cover mixed-income housing developments. SB 35, which is scheduled to sunset in 2026, was signed into law in 2017 and has produced thousands of new subsidized affordable homes across California. The permanent extension of SB 35 via SB 423 will make its provisions permanent, reducing housing costs while ensuring that new affordable and mixed-income homes are built faster in the places they’re most needed.
