1. Permit & Zoning Compliance
All ADUs must be legally permitted by the City of Berkeley. Unpermitted units cannot be legally rented.

Short-term rentals (less than 14 days) are restricted.
Long-term leases (30+ days) are standard and required for detached ADUs under most circumstances.
3. Owner Occupancy
As of 2025, Berkeley no longer requires owner occupancy for ADUs built before 2020. This opens more rental opportunities.

ADUs may or may not have separate utility meters. This should be clarified in the lease agreement.
