ADU Company in Costa Mesa, CA
Kitchen remodeling in Costa Mesa usually means working inside a 1950s or 1960s ranch home where the original footprint is tight, the plumbing is cast iron, and the marine layer has been working on the exterior for six decades. We’re an ADU-focused company, which means we approach kitchens the same way we approach backyard units: plan for the lot constraints first, specify materials that hold up to salt air, and keep the permit path clear from day one. If you’re weighing a kitchen remodel alongside an ADU, call (877) 265-5812 and we’ll help you think through both.
Why Costa Mesa Homes Are Different
The 92627 ZIP, which covers much of the west side, is dominated by 1950s and 60s single-story ranch and bungalow tracts on modest lots, many with detached garages or rear alleys. Those homes were framed when a kitchen was a closed-off room with one electrical outlet per wall, and most have been through at least two partial remodels already. In 92626 you see more 1960s and 70s two-story tracts and apartment buildings, where kitchens are often galley-style and original to the structure. Neither housing stock was built for the way Costa Mesa homeowners live now.
Salt air matters here more than most remodeling companies admit. Costa Mesa sits roughly three miles from the coast, and that marine layer is persistent. Exterior-grade hinges, cabinet hardware, and any metal trim specified for a kitchen that opens to a patio need corrosion-resistant finishes. We spec stainless or powder-coated hardware on exterior-adjacent kitchen work for exactly this reason. Flat or low-slope roofs on detached structures also collect condensation during June gloom, which means a kitchen addition with exterior access needs proper flashing and drainage detailing from the start.
The other Costa Mesa reality is the 50-foot-wide lot on the west side. When a homeowner wants a larger kitchen, the expansion often pushes into the side yard, and that 5-foot side setback decides how far you can go. We’ve worked through enough of these to know that sometimes the smarter move is a modest kitchen bump-out combined with an ADU for the space you actually need, rather than fighting the setback for an addition that eats the whole yard.
Our Main Costa Mesa Services
Most Costa Mesa homeowners who call us are weighing two things at once: adding an ADU in the backyard and fixing the main house so it all works together. These are the two services we handle most often here.
ADU Builders in Costa Mesa
Backyard units are a serious option in Costa Mesa because the city’s ADU ordinance allows two-story detached units and reduced parking requirements, which is not common in Orange County. The challenge is the lot itself: on the west side, a 50-foot-wide parcel with a 5-foot side setback often means a detached ADU has to go where the garage stands or be alley-accessed, not placed as a true backyard new-build. We work with prefab brands like Abodu and Cover as well as site-built construction, so you can compare what actually fits your lot rather than accepting one vendor’s pitch. Learn more on our ADU Builders in Costa Mesa page.
Bathroom Remodeling in Costa Mesa
Bathrooms in Costa Mesa’s 1950s and 60s ranch homes are usually five-by-eight boxes with original cast iron drain lines and one small window, if that. The work here is often about moving a wall six inches to fit a shower where a tub was, or re-routing plumbing that has been patched over by previous owners. Because we also build ADUs, we coordinate bathroom work with the main house so you’re not tearing up the same wall twice if you add a backyard unit later. See what’s involved on our Bathroom Remodeling in Costa Mesa page.

Kitchen Remodeling in Costa Mesa
A kitchen remodel in Costa Mesa usually means opening up a closed-off 1950s or 60s kitchen inside a home that was never designed for the way we cook now. The salt air from the coast means we specify corrosion-resistant hardware and finishes, especially anywhere the kitchen connects to outdoor space. We also think about lot lines: on a 50-foot-wide west-side lot, a kitchen bump-out competes with the side setback, and sometimes the better answer is a more efficient kitchen footprint paired with an ADU for the added square footage. For the full scope of what Kitchen Remodeling involves, our service hub covers the process in detail.
Galley Kitchen Opening
Signs you need it
The kitchen is a narrow corridor with one path between counters, no room for two people to work, and a wall separating it from the living area that makes the whole house feel smaller than it is.
What it costs in Costa Mesa
Removing a non-load-bearing wall and opening the kitchen to the living space typically runs $18,000 to $45,000 in Costa Mesa, depending on whether plumbing or electrical needs to move.
How we do it
We verify whether the wall is load-bearing, pull permits if structural work is needed, relocate plumbing and electrical as required, install a flush beam if necessary, and finish with flooring and ceiling patching so the two rooms read as one space.
Full Kitchen Renovation
Signs you need it
Cabinets are delaminating from decades of coastal humidity, the layout wastes whatever square footage the home has, and appliances are fighting for space with no dedicated prep area.
What it costs in Costa Mesa
A full kitchen renovation in Costa Mesa, with new cabinets, counters, flooring, and some layout changes, generally falls between $35,000 and $80,000, though a whole-room reconfiguration with walls moving can pass $100,000.
How we do it
We start with a measured floor plan, order cabinets and countertops to fit the existing or revised footprint, remove the old kitchen down to the studs, update plumbing and electrical to current code, then install finishes with marine-tolerant materials where the kitchen opens outside.
What Kitchen Remodeling Costs in Costa Mesa
| Item | Typical range in Costa Mesa |
|---|---|
| Galley kitchen opening (non-load-bearing wall) | $18,000 – $45,000 |
| Full kitchen renovation, standard finish level | $35,000 – $80,000 |
| Kitchen with wall relocation or structural change | $80,000 – $100,000+ |
Costs in Costa Mesa push higher when a kitchen expands into the side yard and hits setback restrictions, or when original cast iron drain lines need replacement. We write line-item quotes and hold to them, so the number you approve is the number you pay.
How long does a kitchen remodel take in Costa Mesa?
Plan on six to twelve weeks for a full kitchen renovation, depending on cabinet lead times and whether we’re moving walls or plumbing. A simpler opening of a non-load-bearing wall can be done in two to three weeks. Call (877) 265-5812 for a timeline based on your actual scope.
Do I need a permit to remodel a kitchen in Costa Mesa?
Yes, for any work that moves walls, relocates plumbing or electrical, or changes the footprint. We pull permits and schedule inspections as part of the job. Call (877) 265-5812 if you want to know whether your specific project needs one.

FAQs About ADU Company in Costa Mesa
Start timing depends on Costa Mesa’s current permit intake and the scope of your project. A single-service kitchen or bath remodel typically begins within a few weeks of signed plans; an ADU that needs plan check and two-story review takes longer. Call (877) 265-5812 and we’ll give you a realistic start window for your specific job.
Costa Mesa has HOAs in several east-side and newer developments, and while state ADU law limits what HOAs can prohibit, your HOA may still have architectural review requirements for exterior changes. We help you identify what applies to your property before you commit to a design. Call (877) 265-5812 if you’re not sure what your HOA requires.
Yes, and that’s often the most efficient path in Costa Mesa, where a kitchen or bath remodel can share a permit submittal, a construction crew, and a site plan with an ADU. You avoid paying for mobilization twice and the work is coordinated instead of sequenced awkwardly. Call (877) 265-5812 to talk through whether a combined scope makes sense for your lot.
