Permitting & timeline in Cameron Park
Cameron Park ADU permits are issued by the El Dorado County Planning & Building Department, since this area is unincorporated and reviewed at the county level. 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.
