ADU Company in Costa Mesa, CA
Kitchen remodeling in Costa Mesa usually means reworking a 1950s-to-1970s floor plan inside a home that was never designed for how families cook and gather now. The older 92627 Westside stock has tight galley kitchens original to the house, while 92626 tract homes tend toward dated oak cabinets and fluorescent soffits. This page covers what kitchen work actually costs here, how Costa Mesa’s mild coastal air and older framing shape the job, and what Holloway ADU Builders does differently when we rebuild a kitchen in this city.

Why Costa Mesa Homes Are Different
Costa Mesa runs its own ADU and building-permit shop, and that local control shows up in kitchen remodels too. The city’s Westside, especially the 92627 ZIP, is full of 1950s and 1960s small single-family homes and older duplexes on narrow lots. Many of those kitchens sit over original slab or post-and-pier foundations, with cast-iron drain lines and 60-amp or 100-amp service panels that were fine for a 1962 range but choke a modern kitchen with an induction cooktop, double oven, and undercabinet lighting. In 92626, the Mesa Verde and Mesa del Mar neighborhoods have larger 1960s and 1970s tract homes with HOA and CC&R layers that can add an approval step even for interior-only work. The climate matters less for freeze protection and more for moisture: Costa Mesa sits about two miles inland, so the marine layer means we spec rust-resistant hardware and pay attention to ventilation where older walls have absorbed decades of coastal humidity. Older Costa Mesa kitchens also tend to share walls with garages or additions, which changes how we route new gas, electrical, and vent lines.
Our Main Costa Mesa Services
Costa Mesa homeowners call us most often about two things: building an ADU on a tight Westside lot, and bringing an aging bathroom up to modern standard. Here’s what each involves in this city.
ADU Builders in Costa Mesa
Most Costa Mesa ADU jobs are detached garage conversions or two-story-over-garage rear units, because the Westside’s lots leave almost no open yard for a ground-up build. The city’s local ordinance and fire-access rules mean every plan gets threaded around parking, setbacks, and alley access – work that looks very different from the wide-lot ADUs built in South County. We walk each lot with an eye on what Costa Mesa will actually permit, then match the lot to prefab, modular, or site-built options. ADU Builders in Costa Mesa covers that process in detail.
Bathroom Remodeling in Costa Mesa
Costa Mesa’s older homes often have a single bathroom on original plumbing, and many of those sit in tight floor plans that were laid out before exhaust fans became standard. Coastal moisture is the quiet problem here: poor ventilation in a 1960s bathroom leads to mildew and rusted fixtures years before the tile fails. We address the moisture control first, then rebuild the layout, finishes, and lighting. Bathroom Remodeling in Costa Mesa explains the typical scope and costs.

Kitchen Remodeling in Costa Mesa
Kitchen remodeling in Costa Mesa splits into two broad jobs: a cosmetic refresh of an existing layout, and a full reconfiguration that moves walls, plumbing, or gas lines. Most Westside galley kitchens can’t accept an island without taking space from a dining room or an adjacent bedroom closet, so the first question is always what the lot and floor plan will support. In 92626, homeowners often have more square footage but face HOA review when the work touches a shared wall or changes window openings. Our team handles the permit path either way, and we bring the same crew from drywall to cabinet install. You can read more about our approach at Kitchen Remodeling.
Kitchen Layout Reconfiguration
Signs you need it
Your Costa Mesa kitchen has the original 1960s galley footprint, every cabinet is on one wall, and two people physically cannot cook in the room at the same time.
What it costs in Costa Mesa
A layout reconfiguration in Costa Mesa typically runs $28,500 to $55,000 depending on how many walls, drain lines, and circuits move.
How we do it
We confirm the load-bearing walls and existing slab conditions on your Costa Mesa lot, pull the city permit, rough in new plumbing and electrical, then rebuild the floor plan, drywall, cabinets, and countertops in sequence.
Kitchen Finish Replacement
Signs you need it
The layout works, but the oak cabinet faces are delaminating, the laminate counters are chipped, the appliances are 20 years old, and the fluorescent soffit dates the room.
What it costs in Costa Mesa
A finish replacement in Costa Mesa typically runs $18,000 to $34,500 when the existing layout, gas line, and plumbing stay in place.
How we do it
We demo the old surfaces down to the studs, upgrade any insufficient outlets or ventilation, install new cabinetry, countertops, and a tile backsplash, then trim out the room and handle the City of Costa Mesa final inspection.

What Costa Mesa Customers Say
"Every invoice was tied to a completed milestone, so I always knew what I was paying for."
— Justin Kim"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."
— Rachel Brooks"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
