Your West Sacramento ADU builder — from design to move-in
Bridge District growth and proximity to downtown make West Sacramento ADUs quick to rent.
We build every type of ADU in West Sacramento with one transparent, all-in price and a $1,000 deposit — the California legal maximum — then tie the rest of your payments to inspection-passed milestones so money only moves when verified work is done. When it's ready to rent, we'll connect you with a trusted local property manager.
West Sacramento lots: Southport is newer, flatter, and built for a backyard unit. Broderick and the older grid carry detached garages and long parcels that read as conversion candidates first, ground-up builds second.

West Sacramento ADU rules & limits
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.
Statewide, every West Sacramento ADU under 750 sq ft is exempt from impact fees, detached units can reach 1,200 sq ft, and no replacement parking is required when you convert a garage. For the full Yolo County rulebook — setbacks, height, and owner-occupancy by ADU type — see our Sacramento-region ADU rules & setbacks guide.

Permitting & timeline in West Sacramento
West Sacramento ADU permits are issued by the City of West Sacramento Community Development Department (Yolo County). California law requires a decision within 60 days of a complete submittal, and pre-approved plan sets can shorten review to about 30 days. We prepare the full package, pull the permit, and manage every inspection so you never stand in line at a counter.
Plan on roughly 6–9 months end to end for a detached build: about 2–6 weeks of design, 4–10 weeks of permitting, and 12–16 weeks of construction. Garage conversions and junior ADUs move faster.
The Upside Guarantee
Your money is protected at every step
Sacramento homeowners were burned by builders who took huge deposits and vanished. We built Upside to be the opposite — structured so you're protected before, during, and after the build.
$1,000 down — the legal maximum
California caps a contractor's down payment at $1,000 or 10% of the contract — whichever is less. On an ADU that's $1,000, not the 30–50% other builders demanded. Everything after is earned.
Inspection-tied milestone draws
After the deposit you pay in defined draws — design, permit, foundation, framing, MEP, drywall, completion — each released only after that phase passes inspection.
Honest capacity & timelines
We only take on work we can actually deliver, with realistic schedules and references to completed local projects you can visit.
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 build is fixed-price, inspection-milestone funded, and backed by our written guarantee.
