Oakland ADU permits and regulations 2021
More than 400 ADUs (accessory dwelling units) were permitted in Oakland, California, back in 2018—even before favorable laws were enacted. While that sounds promising, the city as of 2021 has a reputation for being somewhat difficult when it comes to building ADUs.
The Center for Community Innovation at UC Berkeley gives Oakland’s ADU program a grade of B+ on its ADU California website. The resources below will also help you in evaluating whether building an ADU in Oakland is the right choice for you.
