What is an ADU and what does it cost in Sacramento?

An accessory dwelling unit (ADU) is a self-contained second home with a kitchen, bath, and private entrance on a single-family lot. In Sacramento, most ADUs cost $165,000-$500,000 turnkey in 2026, or roughly $250-$360 per square foot for a detached build, with garage conversions starting near $95,000.

After the build

Don't want to be a landlord?

We're builders first — but we won't leave you stuck running a rental. When your ADU is move-in ready, we'll introduce you to vetted Sacramento property managers we trust to lease it, screen tenants, and handle the day-to-day.

  • Vetted, local property-management partners
  • Completely optional — plenty of owners self-manage
  • Honest rent & ROI guidance before you build

Built-in protections — not marketing promises

Every contract we sign carries the same legal structure. Here's exactly what that means for you.

$1,000
Max deposit (the legal cap)

California law caps the down payment at $1,000 or 10% — whichever is less. On an ADU, it's always $1,000.

Escrow
Escrow-protected milestone draws

Every payment is tied to a completed, inspected phase. No phase passes — no draw released.

Feasibility estimate

On a 6,000 sq ft lot in Sacramento, you can likely build a detached ADU up to 900 sq ft (scaling for lot size; state max is 1,200 sq ft), plus a JADU up to 500 sq ft within your main home — for a total of up to 2 units on your lot. Minimum setbacks are 4 ft from side and rear property lines.

Estimates based on general 2026 Sacramento-region ADU guidelines. This is not a zoning determination. Actual feasibility depends on your parcel, existing structures, and local permitting — confirmed in a free on-site check.

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.

Questions Sacramento homeowners ask

Most Sacramento ADUs cost $165,000–$500,000 in 2026 depending on size and type. Garage conversions start near $95,000, and mid-range detached units run about $250–$360 per square foot turnkey.

We handle everything — feasibility, design, engineering, permitting, and construction — as one accountable team. When it's ready to rent, we connect you with a trusted local property manager.

California law caps a contractor's down payment at $1,000 or 10% of the contract, whichever is less — so on an ADU it's $1,000. From there you pay in defined milestone draws (design, permit, foundation, framing, MEP, drywall, completion), each released only after that phase passes inspection.

Yes. We're an ADU builder, not a property manager — but once your unit is move-in ready we'll connect you with vetted local property managers we trust to lease it, screen tenants, and run it for you.
