Irvine is where accessory dwelling units make the most sense of these five cities, and where the rules need reading most carefully. The houses are sound so budget is not consumed by remediation, and the city is inland so no coastal review applies. The variable is the planned community — associations govern exterior appearance and yard structures in ways that differ from one to the next.
Real projects. Real prices.
73 finished remodels published with their final price — nothing hidden.
What our finished LA work actually cost: 27 kitchens ran $23k–$84k, median $50k; 28 bathrooms $28k–$105k, median $38k; 17 whole-home remodels $36k–$440k, median $150k. Real final prices from our own job records, not estimates.
$30,000 A deep navy wall over textured white tile, with a floating walnut vanity and matte black fittings.
$34,800 White uppers over warm grey shaker lowers, white quartz, and a stainless chimney hood.
$45,000 Rust and blue slate-tone tile over a pebble mosaic shower floor, with bronze fittings.
$72,000 White shaker cabinetry against a deep teal backsplash, with an island under a stainless hood.
$150,000 A cobalt glass-tile backsplash with marble-look slab baths in brushed brass.
$440,000 Stone-look tile bathrooms with freestanding tubs, under an exposed beam ceiling.
Adding a unit in a planned community
No coastal review, city rules apply
Irvine sits outside the coastal zone, so that step is absent entirely. The city's requirements and state ADU law still govern.
Read the association rules, do not assume them
Association rules vary. Some are permissive about garden structures, some are not. We establish what actually governs a specific property rather than working from a general impression of how Irvine communities operate.
