West Sacramento rules that affect a multigen adu
West Sacramento multigenerational builds are designed single-level and accessible — zero-step entry, wider doorways, curbless showers — so parents or adult kids live independently next door. Yolo County permits these like any detached or attached ADU.
Local permitting: West Sacramento sits in Yolo County and permits through its own Community Development Department — a separate process from the City of Sacramento across the river. Standard 4 ft setbacks and 16 ft height apply; older Broderick lots often have detached garages well suited to conversion.
That's the multigen adu-specific picture. For the full Yolo County rulebook — every setback, height, and owner-occupancy detail — see our Sacramento-region ADU rules guide, and learn how the build type works statewide on our multigenerational adu page.

Multigen ADU projects in West Sacramento
West Sacramento splits cleanly: Broderick's older grid is conversion territory, with detached garages that come up to code as living space, while Southport's newer lots take a ground-up backyard build. Both run through Yolo County's process, not the city across the river. Every multigen adu is fixed-price, funded on inspection-passed milestones, and backed by our written guarantee.
