ADU Company in Costa Mesa, CA
Kitchen remodeling in Costa Mesa usually costs between $35,000 and $85,000 depending on the size of the space and whether you’re moving plumbing or load-bearing walls. Because so many Costa Mesa homes were built in the 1940s through the 1970s, the work often includes rewiring, repiping, or panel upgrades before the first cabinet goes in. That’s the part out-of-town estimates miss, and it’s why we quote with the house’s actual systems in mind, not a generic square-foot multiplier. Call (844) 386-2399 for a free estimate.
Why Costa Mesa Homes Are Different
Costa Mesa’s housing stock splits sharply by ZIP code, and that split changes the way an ADU or kitchen job should be planned. In 92627 on the west side, you’re mostly looking at bungalows and single-family homes from the 1940s through the 1960s on compact lots. These houses often have detached garages, older electrical panels, and plumbing that has been patched together over decades. In 92626 on the east side, the lots are larger and the homes are 1960s and 1970s tract builds, which means more room for a detached ADU but also the same era of wiring and sewer lines. The marine layer rolls in most mornings, so exterior finish choices and ventilation matter more than people expect. And during Santa Ana wind events, anything built tight to a property line needs fire-resistant detailing the city will actually check. Costa Mesa has its own ADU ordinance layered on top of California state law, with specific setback, height, and parking rules. A contractor who only knows the state code will burn weeks on plan checks.
Our Main Costa Mesa Services
Most Costa Mesa homeowners call us about one of two things: adding an ADU to a property they already own, or upgrading a bathroom inside a house that hasn’t changed much since the Nixon administration. Below is how we approach each one here.
ADU Builders in Costa Mesa
In Costa Mesa, the classic ADU play depends on which side of town you’re on. West-side 92627 properties favor garage conversions, while east-side 92626 lots give you room for a detached unit in the yard. We build both, and we work across prefab platforms including Abodu, Cover, and Tuff Shed conversions, so the recommendation fits the lot and the budget rather than the other way around. The detail most homeowners miss is that many older Costa Mesa garages were never built to current seismic or energy standards, which means foundation and lateral work before the walls go up. Read more about how we handle this at ADU Builders in Costa Mesa.
Bathroom Remodeling in Costa Mesa
Bathrooms in Costa Mesa’s older housing stock are small, and that’s actually an advantage. We regularly expand a 1950s Jack-and-Jill or hallway bath into a more functional space by borrowing a few square feet from a closet or reconfiguring the wet wall. Older west-side homes often need drain line replacement, which is exactly the kind of buried scope item that turns a bid into a change order if it’s ignored. We identify it up front. See how we approach the work at Bathroom Remodeling in Costa Mesa.

Kitchen Remodeling in Costa Mesa
Every Costa Mesa kitchen remodel starts with one question: what’s hiding behind the 1960s drywall? In the older 92627 bungalows and the 92626 tract homes alike, we routinely find cloth-wrapped wiring, galvanized supply lines, and panels that won’t pass a modern load calculation. The city inspects all of it, so we price it in. The coastal climate also means we choose finishes that handle the marine layer without warping or trapping moisture, and we vent for it properly. This is the work covered on our Kitchen Remodeling page, and here’s what it looks like on the ground in Costa Mesa.
Full Kitchen Remodels
Signs you need it
Your layout doesn’t work for how you actually cook, the cabinets are delaminating, or you’re planning an ADU and want the main house kitchen to stop being the bottleneck.
What it costs in Costa Mesa
A full kitchen remodel in Costa Mesa, including new layout, cabinets, countertops, and finishes, typically runs $45,000 to $85,000 depending on cabinet grade and how much plumbing or electrical moves.
How we do it
We open walls to verify framing, wiring, and plumbing, then order cabinets and stone once the rough-in is locked, not before, so lead times don’t fight the schedule.
Cabinet Refacing and Countertop Replacement
Signs you need it
The layout works and the cabinets are structurally sound, but the doors, drawer fronts, and countertop surfaces have outlived their finish.
What it costs in Costa Mesa
Cabinet refacing with new hardware and a stone or quartz countertop in Costa Mesa typically runs $12,000 to $25,000 depending on surface area and slab material.
How we do it
We template after the boxes are confirmed square, replace faces and hardware in place, then set counters on schedule without leaving the kitchen unusable for more than a few days at a time.

Do I need a permit to remodel my kitchen in Costa Mesa?
Yes, if you’re moving plumbing, electrical, or walls, Costa Mesa requires permits and inspections. Cabinet refacing and countertop-only jobs usually don’t need one.

What Costa Mesa Customers Say
"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Sarah Kowalski"The kitchenette layout he suggested made better use of the space than the one on our original sketch."
— Christine Park"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."
— Diego Delgado
