ADU Guide: Building an Accessory Dwelling Unit in Blair Hills

State law vs local rules

California Government Code 65852.2 (the state ADU law) sets a floor: every single family lot can have at least one ADU plus one Junior ADU. Cities can add layers on top but cannot block ADUs entirely. Blair Hills has its own ordinance that further shapes setbacks, height, and lot coverage.

Site feasibility

Before design, walk the lot for setbacks, sewer capacity, electrical service capacity, slope, and easement constraints. Detached new build ADUs need a footprint and yard space. Garage conversions reuse an existing structure. Junior ADUs sit inside the main house. Each path has its own cost basis and construction timeline.

Permits in {city}

ADU submittals are ministerial in California, meaning the city reviews them administratively without discretionary review. City of Culver City Building Safety Division, 9770 Culver Blvd. typically completes plan check in 60 to 120 days. About 225 homes on steep, winding streets. Culver City’s pre reviewed ADU plan program includes a Mid Century compatible design that fits the neighborhood. Garage conversions usually clear faster than detached new builds.

Construction window

Site clearance, foundation, framing, MEP rough, exterior dry in, interior finish, fixture install, final inspection. ADU builds in Blair Hills typically run 4 to 7 months of construction. From signed design contract to final inspection most projects total 8 to 14 months.
