Adding an ADU in SF Bay Area.

[Andy C.]

Hi Bigger Pockets, I currently live in the San Francisco Bay Area. San Mateo to be exact. I'm trying to find out more information about San Mateo County and what homeowners can do to potentially add an ADU or accessory dwelling unit. Has anyone on BiggerPockets who also live in the SF Peninsula Bay Area had experience with successfully adding one to their property? Appreciate any help or advice in advance. Andy Chang
