ADU Builder in Culver City, CA: Permits, Pre-Approved Plans and Costs

How does Culver City review an ADU permit?

Culver City processes ADU permits ministerially through the Building Safety Division. State law caps the city's decision at 60 days from a complete application, and 15 business days to confirm completeness, under Gov. Code section 66317(a)(2) and 66317(a)(3). The Planning Division reviews plans for compliance with local zoning standards before building permit issuance.

What pre-approved ADU plans does Culver City offer?

The city's Pre-Approved ADU (PRADU) Program, launched with the ADU Handbook in March 2024, provides three floor plans in three styles. The plans come in 468 sq ft (studio), 637 sq ft (one bedroom), and 806 sq ft (two bedroom) layouts. Architectural styles are Post-War Bungalow, Spanish Revival, and Contemporary. Since January 1, 2025 any homeowner can submit a custom ADU design for pre-approval under Assembly Bill 1332.

What size ADU is allowed in Culver City?

A detached ADU on a Culver City lot may be built up to 1,200 sq ft under state law (state ceiling). State law requires Culver City to allow at least an 800 sq ft detached ADU with 4-foot setbacks (city minimum protection), and at least 850 sq ft (one bedroom) or 1,000 sq ft (two bedroom) of livable space, under Gov. Code section 66321(b)(2) and 66321(b)(3). Detached ADUs can reach 16 feet in height, 18 feet within half a mile of a major transit stop, and 25 feet for attached ADUs, per Gov. Code section 66321(b)(4).

What fees and impact charges apply to a Culver City ADU?

Impact fees on ADUs under 750 sq ft are limited by Gov. Code section 66311.5(c)(1). Local schools and districts may still charge proportional fees for units over that size. Culver City collects development impact fees, school fees, and Building Safety plan-check fees before permit issuance. The exact Culver City fee total is not published on the ADU webpage and is set during the plan-review phase.

How much does an ADU cost in Culver City?

L Square's configured prefab ADU models start at $180,000 for the 600 sq ft Model 600 and run up to $354,000 for the 1,200 sq ft Model 1200. Mid-range options include Models 800A and 800B at $240,000 (800 sq ft, two bed, two bath) and Models 1000A and 1000B at $295,000 (1,000 sq ft, three bed, two bath). The final cost depends on site conditions, sewer route, utility capacity, and slope, so a property-specific proposal is needed.

What to check before building an ADU in Culver City

Confirm the lot's zoning allows an ADU, identify the sewer lateral route, and verify utility capacity with the Building Safety Division. Review the PRADU plan set first if the property can fit a 468, 637, or 806 sq ft footprint. If a custom design is planned, check setbacks of 4 feet on side and rear, height ceilings of 16 to 18 feet, and parking exemption rules under Gov. Code section 66322. Confirm permit fees with Culver City Planning before signing a contract.
