Once seen as the death knell for single-family neighborhoods in California, a new law meant to create more duplexes has instead done little to encourage construction in some of the largest cities in the state, according to a new report published Wednesday.
Senate Bill 9 was introduced two years ago as a way to help solve California's severe housing crunch by allowing homeowners to convert their homes into duplexes on a single-family lot or divide the parcel in half to build another duplex for a total of four units. The law went into effect at the start of 2022.
The bill received bipartisan support and ignited fierce debate between its backers, who said SB 9 was a much-needed tool to add housing options for middle-income Californians, and critics, who blasted it as a radical one-size-fits-all policy that undermined local government control.
