ADU Builder in Sacramento, CA
An ADU (accessory dwelling unit) is a second home on your lot — a backyard cottage, a converted garage, or a unit attached to your house. Sacramento homeowners build them for aging parents, adult kids, rental income, or a place to work.

Straight answers
ADUs questions, answered
How much does an ADU cost in Sacramento?
Typical 2026 ranges for the ADU cost in Sacramento:
- Detached ADU: $180,000–$450,000
- Garage conversion ADU: $95,000–$220,000
- Attached ADU: $180,000–$270,000+
Size, utilities, site work, and finishes move the number most. Our 2026 Sacramento ADU price guide breaks it down. You get one clear, fixed price in writing after we walk your lot.
Is a garage conversion ADU cheaper than a detached ADU?
Usually, yes. A garage conversion ADU reuses a slab, walls, and roof that already exist. You still need insulation, windows, plumbing, electrical, and a kitchen and bathroom — and the existing garage has to meet code for living space. We'll tell you at the walkthrough whether your garage is a good candidate.
Do you handle the ADU permits?
Yes. We handle the applications, plan check, corrections, and inspections. You don't chase the city — we do.
How long does an ADU take?
It depends on the type of ADU, how fast plan check moves, and how much site work your lot needs. We won't guess before we've seen the property. After the walkthrough, your scope comes with a written schedule, and you get photo updates each week once building starts.
What slows an ADU down?
The most common delays are plan check corrections, utility upgrades (like a bigger electrical panel or a new sewer line), and design changes after permits are issued. We flag these risks at the first walkthrough so they don't surprise you later.
How much is the deposit?
No big check up front. California law caps the down payment on a home improvement contract at $1,000 or 10% of the contract price, whichever is less — and we follow it. After that, each payment is tied to a finished phase of work, listed in your contract. You never pay ahead of the work.
