This recent article by Bloomberg CityLab, about "how California set off a backyard apartment boom," has some interesting stats about the extent in which accessory dwelling units (ADUs) are quickly being adopted and delivered across the state.
For one, a majority (87%) of jurisdictions have enacted at least one ordinance related to ADUs, though many have several. These policies might include everything from by-right zoning to some form of financial assistance if you build. Here is a graph showing the cities and counties that have created ADU ordinances since 2013:
All of this has translated into housing supply. In 2019, California homeowners brought over 12,000 accessory dwelling units to the market (based on permits issued). Though a relatively small quantity based on the state's overall housing deficit, this number is surely growing thanks to policies and programs, like this one here , that are working to remove the barriers to building.
