ADU Company in Costa Mesa, CA
Kitchen remodeling in Costa Mesa usually means opening up a tight 1950s-era galley, moving walls, and updating wiring that’s older than most of the people living in the house. We handle those jobs all the time, and the difference in this city comes down to the housing stock: single-story stucco tract homes with closed-off kitchens that were never designed for how families cook and gather now. Whether your home is in 92626 or 92627, call us at (844) 978-0086 to talk through what a remodel would cost on your specific floor plan.
Why Costa Mesa Homes Are Different
Costa Mesa’s housing stock runs from post-war tract homes built between 1950 and 1975 to a mix of older bungalows on the Westside and larger custom builds in the 92626 ZIP code. That era matters for kitchen work: the original kitchens in these homes were built small and closed off, with the assumption that one person cooked while everyone else stayed in the living room. Opening one up almost always means structural changes, because the walls enclosing a 1950s kitchen are often load-bearing.
The climate also shapes how we approach interior work here. Costa Mesa gets very little rain, so moisture damage is rarely the driving issue. What we deal with instead is summer heat and Santa Ana winds, which push dust through older single-pane windows and make ventilation a priority. When we rework a Costa Mesa kitchen, we plan for airflow and insulation because a closed-off cooking space in an east-facing tract home can get uncomfortably warm by mid-afternoon. Detached garages and wide side yards are common on many of these properties, which occasionally factors in when homeowners want to expand a kitchen outward rather than reconfigure the existing footprint.
Our Main Costa Mesa Services
Two services dominate the calls we get from Costa Mesa homeowners: ADU construction and bathroom remodeling. Here’s what each involves in this city.
ADU Builders in Costa Mesa
Detached ADUs make sense on the generous lots in 92626, where 1950s and 1960s tract homes leave room for a separate unit set back from the street. Over in 92627, the Westside’s narrower lots and alley-loaded garages change the calculus, and homeowners there often ask us whether a garage conversion or two-story unit makes better use of the space. We walk through those options in detail on the dedicated page for ADU Builders in Costa Mesa.
Bathroom Remodeling in Costa Mesa
Original bathrooms in Costa Mesa’s post-war homes are small, with cast-iron tubs, old tile set in mud beds, and single vanity setups. Remodeling one of these often means reworking the drain layout and bringing wiring up to current code, especially in 92627 bungalows where space is tight. See how we approach these projects on the Bathroom Remodeling in Costa Mesa page, including typical timelines for homes of this era.

Kitchen Remodeling in Costa Mesa
Costa Mesa kitchens from the 1950s and 60s were built for a different way of living: closed off, small, and separated from everything else. Most homeowners here want the wall between kitchen and dining room gone, new cabinets that actually hold a modern family’s cookware, and an island where everyone ends up standing anyway. The plumbing and electrical in these homes are original in a lot of cases, so a real remodel usually includes upgrading both. For a wider look at how we scope kitchens, see our Kitchen Remodeling page.
Full Kitchen Gut and Rebuild
Signs you need it
The cabinets are particleboard from the Carter administration, the floor has three layers of vinyl, and the layout still assumes the kitchen is a room you close the door on.
What it costs in Costa Mesa
A full gut and rebuild in Costa Mesa typically runs $65,000 to $120,000, depending on the size of the footprint and whether you’re moving plumbing.
How we do it
We strip to studs, rewire and replumb, reframe for the new layout, then build back with new cabinets, countertops, flooring, and a proper ventilation setup rated for how you actually cook.
Open-Concept Wall Removal
Signs you need it
The kitchen is fine functionally but you feel walled off from the rest of the house every time you host, and the dining room only gets used twice a year.
What it costs in Costa Mesa
Removing a wall between the kitchen and living or dining space in Costa Mesa generally falls between $10,000 and $25,000 when the wall is load-bearing.
How we do it
We identify which walls are structural, size and install a beam or header to carry the load, reroute any electrical or plumbing in the wall, and finish the ceiling and floor transitions so it reads as one room.

Will a Costa Mesa kitchen remodel require a permit?
Yes, any work involving structural changes, electrical, or plumbing requires a permit from the City of Costa Mesa. We handle the permit application, plans, and inspections as part of the contract. Call (844) 978-0086 to ask about your specific scope.
