ADU Company in North Tustin, CA

Kitchen remodeling in North Tustin almost always means working inside a ranch or mid-century custom home built between the 1950s and 1970s, on a half-acre to full-acre lot with mature trees and an older electrical panel that predates modern appliance loads. Cottage ADU Builders has served North Tustin since 2012, and we approach every kitchen here with the same question we ask on our ADU projects: what does this specific parcel, this specific house, and this specific county jurisdiction actually require? Call (866) 808-7312 to talk through your kitchen with someone who knows the difference between city permits and Orange County permits.

Why North Tustin Homes Are Different

North Tustin is an unincorporated county island, which means Orange County, not the City of Tustin or Santa Ana, reviews the permits. That changes everything about how a job moves through plan check, what setbacks apply, and who signs off at inspection. The housing stock runs heavily to single-story ranch and two-story mid-century custom homes from the 1950s through the 1970s, many of them on irrigated lots with established avocado and citrus trees, detached garages, barns, and in some cases private wells and septic systems still in service. That means a kitchen remodel here is rarely a simple swap of cabinets and counters. We’re often working around old galvanized plumbing, 100-amp panels that need to be upgraded to 200 amps, and floor plans where the kitchen was originally walled off from the living area. The inland foothill climate plays a role too. Summers run hotter here than in coastal Orange County, and Santa Ana wind events hit harder at the base of the Santa Ana Mountains, so ventilation, range hood sizing, and even window placement matter more than a homeowner might expect. We plan kitchens in North Tustin for real heat and real wind, not for a coastal breeze.

Our Main North Tustin Services

Most North Tustin homeowners call us about two things: adding a detached ADU to a large county lot, or reworking a tired bathroom in an older custom home. Both live under one roof here.

ADU Builders in North Tustin

On these big unincorporated lots, an ADU isn’t about cramming a unit into a side yard. It’s about figuring out where a detached structure can sit without colliding with a well, a septic leach field, a horse-keeping easement, or an existing barn. We start with the parcel’s county zoning and utility layout, then match the lot to the right construction system, whether that’s a stick-frame build or a prefab unit from a manufacturer we know well. County plan check on an unincorporated parcel moves differently than city review, and we’ve been through that process enough times in North Tustin to know where the delays hide.

Bathroom Remodeling in North Tustin

Bathrooms in these 1950s-to-1970s homes often carry original cast-iron drain lines, small windows, and no dedicated exhaust fan, which matters in a climate with hot, dry summers. A remodel here frequently means opening walls to replace old supply and drain piping before any tile goes down. We handle that without pushing the job into a second contractor. Details on scope, timing, and what to expect are on the Bathroom Remodeling in North Tustin page.

Kitchen Remodeling in North Tustin

Kitchen remodeling in North Tustin usually means taking a closed-off, original 1950s-to-1970s kitchen in a ranch or mid-century custom home and opening it to the living space, replacing aged plumbing and an undersized electrical panel along the way. The inland heat and Santa Ana winds mean we spec ventilation and cooling loads differently here than we would closer to the coast. Whether the project is a cabinet-and-counter refresh or a full down-to-studs rework, Kitchen Remodeling is a core part of what we do, and you can read more about our general approach on that page before you call.

How we do it

We measure the existing footprint, order cabinets and slab, remove the old boxes and counters, then install and level the new work in place.

Full Kitchen Gut and Rebuild

What North Tustin Customers Say

★★★★★ 4.8 from 4+ reviews

"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."

— Ernesto Hernandez

"Unit came out great and the tenant is happy. The timeline ran long, largely because of how slow the city was on plan check, though a couple of the delays were scheduling on their end."

— Shane Miller

"Garage conversion to a one bedroom unit. He handled the plans, the city submittal, and every round of corrections. Took six months from first meeting to final inspection and he never once made the permit process my problem."

— Amanda Walsh
