Oakland ADU Regulations

• ✓Explicit split between single-family and multifamily ADU application tracks
• ✓Pre-approved standard plans program — faster review and lower plan-check fees
• ✓AB 2533 / state legalization context for qualifying unpermitted units
• ✓JADU + multiple category ADUs potentially combinable subject to city rules

JADU up to 500 sq ft (owner-occupancy rules apply). Category One (conversion / minimal expansion) and Category Two (new construction) pathways. Multifamily has its own Category One–Three structure.

State guarantee: California requires every city to allow at least an 800 sq ft ADU exempt from local lot coverage, FAR, and front-setback rules.

Height baseline: 16 ft for detached, rising to 18 ft within ½ mile of major transit. Attached ADUs follow the primary home, capped at 25 ft.

Governed by state ADU law and Oakland's adopted standards. Specifics depend on ADU category and whether spaces or garages are removed.

Dedicated Oakland services pages for single-family vs multifamily ADU applications. Pre-approved standard plans program offers streamlined review and lower review fees.

State backstop: A complete ADU permit must receive a decision in 60 business days. If the city stalls past 30 business days, AB 253 lets you hire a certified private plan checker to force a 10-business-day decision.

Reduced plan-review cost when using approved pre-approved plans. Other impact, school, and utility fees may still apply depending on size.

SB 543: No impact fees on ADUs ≤750 sq ft. Above 750 sq ft, fees scale to the ratio of ADU size vs the main home.

Standard ADUs in Oakland: no owner-occupancy required (made permanent in 2023).

JADUs: limited to 500 sq ft of interior livable space within an existing single-family home. Owner occupancy is required only when sanitation facilities are shared with the main house. JADUs cannot be used as short-term rentals (AB 1154 / SB 543).
