Fact or Fiction? A Look At Claims About SB 50, One Of California’s Most Controversial Housing Bills
When one of the most contested California housing bills in years resurfaced at the state Capitol this month, so did the heated, often exaggerated claims about how it would ease the state’s affordable housing crisis — or possibly make it worse.
Senate Bill 50, authored by Democratic state Sen. Scott Wiener of San Francisco, would require cities and counties to allow higher-density housing near job and transit centers. Most new units would be priced at the market rate, but the bill requires up to a quarter to be affordable.
In neighborhoods within a half mile of rail stations, ferry terminals and other transit hubs, this "upzoning" would greenlight mid-rise apartment towers of four or five stories. In spots farther from transit and jobs, it would permit dividing homes into duplexes, triplexes and fourplexes in areas previously zoned for single-family homes.
