Culver City ADU: Regulations, Costs & Permits

• Unit count on a single-family lot: one conversion ADU, one new detached ADU, and one JADU.
• Statewide exemption units: a conversion ADU plus a JADU, and a new detached ADU up to 800 sq ft with 4 ft side and rear setbacks, are exempt from lot coverage, front setbacks, and design standards.
• Detached ADUs: up to 850 sq ft with one bedroom or 1,200 sq ft with two or more.
• Attached ADUs: the same 850 or 1,200 sq ft, or 50% of the house, whichever is less. An ADU entirely inside an existing or proposed home has no maximum.
• Minimum: 150 sq ft, including a kitchen and at least a three-quarter bath. ADUs must be fully independent.

• Height: in R1 and R2 zones the zone's residential height limit applies, and 30 ft in other zones. The city can't block an 18 ft detached or 25 ft attached ADU, and detached units near major transit get 2 more ft to match the roof pitch.
• Setbacks: 4 ft side and rear next to residential zones, and just 2 ft where the lot line abuts a street, alley, or mixed-use zone. That 2 ft alley setback is a real advantage on alley lots.
• Front setback: the zone's front setback applies unless the unit is a statewide exemption ADU. Through lots can use a 2 ft setback on one frontage.
• Over a garage: follows the same 2 ft and 4 ft side and rear rules.

• No parking: none for ADUs or JADUs, and no replacement when you convert a garage.
• No design standards: ADUs and JADUs are exempt from the city's Objective Design Standards.
• No owner occupancy: not required for ADUs, and only for a JADU that shares a bathroom with the house.

Culver City's Pre-Approved ADU (PRADU) program offers free plan sets for new detached ADUs in three layouts (a 468 sq ft studio, a 637 sq ft one-bedroom, and an 806 sq ft two-bedroom) and three styles: Post-War Bungalow, Spanish Revival, and Contemporary. You still need a site-specific site plan, and plan check and impact fees still apply. The studio and one-bedroom stay under 750 sq ft, so they avoid impact fees entirely.

Culver City has opted into state law allowing an ADU to be sold separately from the main home as a condominium. It takes a parcel map (for four or fewer units), a safety inspection, your lender's consent, and consent from any existing HOA. Otherwise, rentals must run longer than 30 days.

Culver City kept its earlier Very High Fire Hazard Severity Zone boundaries when the state updated its maps in 2025, and local reporting says the council's June 2025 ordinance added parts of Blair Hills and Lower Culver Crest above the state's recommendation. In very high zones, expect 100 ft of defensible space and wildland-urban interface building codes for new construction. High zones also bring WUI codes and home hardening.

• Submittal: complete plans go to Building Safety through the city's Accela Citizen Access portal. Each structure and trade (building, electrical, plumbing, mechanical, demo, solar) needs its own application.
• Review: Planning review is ministerial, within state timelines, and a denial comes with a full list of fixes.
• Address: file an Address Assignment Request with Current Planning before the building permit is issued.
• Impact fees: only on ADUs of 750 sq ft or more: the Mobility Improvement Fee and the In-Lieu Parkland Dedication Fee, charged in proportion to the house.
• Plan check: the city's 2024 sample packet shows plan check at 75% of the permit fee plus a 4% technology surcharge.
• Legalizing an older unit: unpermitted ADUs built before 2020 can be legalized. The city suggests a confidential inspection by a licensed contractor first.

• Water: Golden State Water or LADWP, depending on your address.
• Electricity: mostly Southern California Edison, with LADWP serving part of the city. Worth knowing if the ADU needs a panel or service upgrade.
