California’s most ambitious housing law is taking full effect on July 1 — it could create a million new apartments and condominiums

Starting July 1, Senate Bill 79 requires cities in eligible California regions to allow denser residential development near major transit stops, unlocking zoning capacity for over a million homes. The law applies to several large urban counties and aims to boost housing supply, support transit ridership, and reduce emissions by overriding certain local zoning restrictions near rail and bus rapid transit corridors.
