Berkeley FAQ
Does Berkeley require me to live on-site if I build an ADU?
No, not for a standard ADU. California Government Code 65852.2(a)(8) preempts owner-occupancy rules, and BMC 23.304 has not adopted such a requirement. The only exception is a Junior ADU - the owner must occupy either the primary house or the JADU under Gov. Code 65852.22.
Can I rent out both my Berkeley house and my ADU?
Yes for a standard ADU - state law allows renting both units as long as each is rented for 30 days or longer. Berkeley's rent-control ordinance (BMC 13.76) applies to all rental units in the city. For a JADU, the deed restriction requires you to live in either the primary house or the JADU.
Do I have to record a deed restriction for my Berkeley ADU?
Only for a JADU under Government Code 65852.22 and BMC 23.304. The deed restriction (owner occupancy, no short-term rental, no separate sale) must be recorded with the Alameda County Recorder before the Certificate of Occupancy issues. Standard ADUs only have a deed restriction against short-term rental.
