ADU Rules in Long Beach, California
ADU Rules in Long Beach
Long Beach follows California's statewide ADU framework established by AB 68, SB 13, AB 881, and AB 2221, with local implementation managed by the Development Services Department.
Permitted ADU Types
- Detached ADU: A standalone structure separate from the primary dwelling, up to 1,200 sq ft
- Attached ADU: An addition to the existing primary dwelling, up to 1,200 sq ft
- Junior ADU (JADU): A unit created within the existing footprint of the primary dwelling, up to 500 sq ft
- Garage Conversion: Converting an existing garage or accessory structure into a dwelling unit
Property owners may build both a full ADU and a JADU on a single-family lot under state law.
Size and Dimensional Standards
| Standard | Requirement |
|---|---|
| Maximum ADU Size | 1,200 sq ft |
| Maximum Height | 16 ft (detached) |
| Rear Setback | 4 ft |
| Side Setback | 4 ft |
| Front Setback | Must comply with underlying zone |
Parking Requirements
No additional parking space is required for an ADU if the property is located within half a mile of public transit, which covers a large portion of Long Beach. Where parking is required, one space per ADU is the maximum the city may mandate. Replacement parking for a converted garage is not required.
Permit Process
- Pre-application consultation: Optional but recommended meeting with Development Services staff
- Submit application: File plans and application through the city's permit center
- Ministerial review: The city has 60 days to approve or deny a complete application
- Building permit: Once approved, obtain building permits and schedule inspections
- Final inspection: Pass all required inspections to receive certificate of occupancy
Fees and Costs
ADUs under 750 square feet are exempt from development impact fees under California state law. For larger units, impact fees are charged proportionally based on the ADU's square footage relative to the primary dwelling. Utility connection fees may apply for detached ADUs with new utility connections.
Key Regulations
- Owner occupancy is not required per current state law
- Short-term rentals (less than 30 days) of ADUs are prohibited under state law
- ADUs cannot be sold separately from the primary dwelling unless specific conditions are met under AB 1033
- The city may not require fire sprinklers in an ADU if they are not required in the primary dwelling
