ADU Builder in Lincoln
Upside ADU is a Lincoln ADU builder serving all of Placer County.

Permits run through the City of Lincoln Building Division, which we handle end to end.
Your Lincoln ADU builder — from design to move-in
Sun City Lincoln Hills drives multigenerational and aging-in-place ADU demand.
We build every type of ADU in Lincoln 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.
Lincoln lots: Twelve Bridges and Lincoln Crossing sit on newer flat pads. In the active-adult tracts the lot matters less than the layout — single-level, zero-step designs are the default.

Lincoln ADU rules & limits
Lincoln's own Building Division reviews ADUs under Placer County rules (4 ft setbacks, 16 ft height). The 55+ context drives the design more than the code does — Sun City Lincoln Hills and Twelve Bridges add HOA architectural review, and most units come out single-level and step-free for aging in place.
Statewide, every Lincoln 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 Placer County rulebook — setbacks, height, and owner-occupancy by ADU type — see our Sacramento-region ADU rules & setbacks guide.

Permitting & timeline in Lincoln
Lincoln ADU permits are issued by the City of Lincoln Building Division (Placer 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.
