ADU Company in Costa Mesa, CA
Kitchen remodeling in Costa Mesa runs $35,000 to $85,000 for a full gut renovation, with smaller refreshes starting around $18,000. Most Costa Mesa kitchens sit inside 1950s westside bungalows or 1960s-70s eastside ranch homes, which means we’re regularly working around dated layouts, failing galvanized plumbing, and paneled walls rather than newer open-concept frames. Cottage ADU Builders has served Costa Mesa since 2012, and we’ve learned that a kitchen here needs different planning than one in a newer tract home – the post-war framing, tight lot lines, and coastal air all shape the job. Call (866) 808-7312 for a free estimate.
Why Costa Mesa Homes Are Different
What we see on the 92627 westside is a specific animal: 1950s bungalows and stucco tract homes on 6,000-square-foot lots, most with detached single-car garages and floor plans that were never designed for the way people cook now. The kitchens in these homes are typically 80 to 120 square feet, closed off from the living space, and built with materials that have had 70 years of coastal air working on them. The 92626 eastside near South Coast Metro has larger 1960s-70s ranch homes with more generous footprints, but those kitchens carry their own patterns – worn formica counters, fluorescent soffits, and cabinets that have drifted out of square on slab foundations.
Costa Mesa’s marine layer means morning fog most of the year and very little rain, which sounds forgiving but isn’t entirely. The humidity near the coast gets into unsealed cabinet boxes and swells doors. And during late-summer Santa Ana wind events, west-facing kitchen walls take direct afternoon heat, so insulation and window placement matter more than people expect. Beyond the weather, Costa Mesa’s council has taken a deliberately pro-housing stance compared to Newport Beach or Huntington Beach, which means remodeling permits here tend to move through a design-review-conscious but comparatively streamlined path. It still takes time, but the process is less adversarial than some neighboring cities.
One more thing about the westside: those nearly identical 1950s garages and the city’s rear-yard setback lines leave a frustratingly narrow buildable strip on many lots. We scout access early, because the difference between a smooth kitchen delivery and a remodel that fights the property line is knowing before the first cabinet order goes in.
Our Main Costa Mesa Services
While kitchen remodeling is the service Costa Mesa homeowners call us about most, two other jobs come up constantly on the same properties – often because someone adding an ADU realizes the main house needs a bath refresh too, or vice versa.
ADU Builders in Costa Mesa
Costa Mesa’s westside is the densest ADU and JADU pocket in Orange County, and we see the full range: garage conversions on 6,000-square-foot lots, new detached units in eastside backyards, and stacked projects where a garage conversion and a new unit go on the same property. The 2010s-era ordinances that allowed motel-to-housing conversions along Newport Blvd and Harbor Blvd set a pro-housing tone that still shapes how permits get reviewed here. We work with prefab and modular systems including Mighty Buildings, Boxabl, and Plant Prefab, which changes the timeline math on a lot of Costa Mesa properties. ADU Builders in Costa Mesa
Bathroom Remodeling in Costa Mesa
Most 1950s westside bathrooms are 5 feet by 8 feet with a cast iron tub, original terrazzo or sheet vinyl, and a single vanity. The pipes under those slabs are original galvanized in many cases, and once walls open, we often find corroded waste lines that need replacing before any finish work starts. Eastside ranch homes have more room, which allows for relocating fixtures and adding showers where tubs once stood. The coastal humidity also means we spec exhaust fans and moisture-resistant drywall that hold up better than what the original builders installed. Bathroom Remodeling in Costa Mesa

Kitchen Remodeling in Costa Mesa
Kitchen remodeling in Costa Mesa is the service we get the most questions about, and the answer always starts with the house itself. A full renovation in a 1950s westside bungalow typically runs $35,000 to $85,000, while an eastside ranch kitchen with more square footage can push toward the top of that range or slightly beyond depending on structural work. Because so many of these homes haven’t been touched since the original build, the job usually includes more than new cabinets – it’s opening walls, replacing failing plumbing, upgrading electrical, and reconfiguring a cramped footprint. Kitchen Remodeling is where we spend most of our Costa Mesa days, and we approach each one from the studs out.
Full Kitchen Renovation
Signs you need it
Your kitchen’s footprint no longer works for how you cook, cabinets are delaminating from decades of coastal humidity, and you’re working around failing outlets, cast iron plumbing, or a layout that closes you off from the rest of the house.
What it costs in Costa Mesa
A full kitchen renovation in Costa Mesa typically runs $35,000 to $85,000 depending on square footage, structural changes, and material selection.
How we do it
We strip the space to studs, replace or reroute plumbing and electrical to current code, reconfigure the footprint where the layout allows, then rebuild with new cabinetry, countertops, flooring, and finishes installed under one contract.
Cabinet Refacing and Countertop Replacement
Signs you need it
Your cabinet boxes are still solid and square, but doors and drawer fronts are worn, hinges are failing, and the countertop surface has chips, stains, or burn marks that refinishing won’t fix.
What it costs in Costa Mesa
Cabinet refacing with new countertops in Costa Mesa generally starts around $18,000 and goes up based on material and edge profile.
How we do it
We measure and order new doors, drawer fronts, and hardware, install new counter surfaces over the existing boxes, and replace hinges and slides so everything closes and sits the way it should.
What Kitchen Remodeling Costs in Costa Mesa
| Item | Typical range in Costa Mesa |
|---|---|
| Full kitchen renovation | $35,000 – $85,000 |
| Cabinet refacing + new countertops | $18,000 – $30,000 |
| Kitchen refresh (paint, hardware, backsplash, lighting) | $8,000 – $18,000 |
Prices shift based on whether we’re opening load-bearing walls, how much galvanized plumbing needs replacing, and what the slab reveals once flooring comes up. Every quote is a written line item, and the price we give you before starting is the price you pay – no change orders spring themselves on you mid-job.
How long does a kitchen remodel take in Costa Mesa?
A full Costa Mesa kitchen renovation typically takes 8 to 12 weeks from demo to final walkthrough, with cabinet refacing and countertop swaps running 3 to 5 weeks. Permit timing with the city can add 2 to 4 weeks before we start. Call (866) 808-7312 and we’ll give you a schedule based on your actual footprint.
Do I need a permit to remodel my kitchen in Costa Mesa?
Yes, any kitchen remodel that moves plumbing, electrical, or walls needs a Costa Mesa building permit, and we pull them for every job. Cosmetic refreshes that leave systems untouched can often proceed without one. We handle the paperwork either way.

What pushes prices up in Costa Mesa is usually hiding inside the walls: original galvanized waste lines on 1950s westside slabs, old knob-and-tube or undersized panels on eastside ranches, and structural work when a load-bearing wall comes out. And the price we quote is the price we hold – every job gets a written line-item estimate, so you can see exactly where the money goes before we ever pick up a tool.

What Costa Mesa Customers Say
"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"The kitchenette layout he suggested made better use of the space than the one on our original sketch."
