ADU Company in Westminster, CA
Kitchen remodeling in Westminster usually means working inside a 1950s or 1960s tract home where the original footprint is small, the plumbing is old, and the wall between the kitchen and living room has probably been removed once already. We handle those conditions every week. Classic ADU Builders has served Westminster since 2015, and our kitchen work is designed around what these houses actually need: better cabinet storage in tight galley spaces, ventilation that handles cooking from a multigenerational household, and finishes that stand up to daily use. Call (877) 265-5587 to talk through your kitchen, bath, or ADU project.
Why Westminster Homes Are Different
Westminster’s housing stock is mostly 1950s through 1970s wood-frame stucco tract homes on 6,000 to 7,000 square foot lots. That means detached garages, narrow side yards, and interiors that were built before open-concept living went mainstream. Kitchens in these homes tend to be compact, often under 120 square feet, with load-bearing walls that complicate any plan to open the space up. We also see a lot of past modifications: enclosed patios, unpermitted room additions, and DIY electrical work, especially in homes near the Little Saigon commercial corridors along Bolsa Avenue and Brookhurst Street. Before we touch a kitchen, we check what was changed over the decades, because untangling unpermitted prior work before a clean remodel is part of doing the job honestly.
The coastal-influenced Orange County climate means mild, dry summers and cool winters. Westminster kitchens don’t need heavy insulation, but the marine layer and occasional Santa Ana winds make ventilation and moisture control the important details. A range hood that actually exhausts outside matters more here than anywhere with real seasons, because windows stay shut less and cooking heat hangs around longer than you’d expect.
Our Main Westminster Services
Most Westminster homeowners call us about two things: building an ADU on a lot that already has a full house, and remodeling a bathroom that hasn’t been touched since the Reagan administration. Here’s what each involves locally.
ADU Builders in Westminster
Westminster’s Little Saigon core is packed with single-story tract homes on modest lots, and the ADU boom here is driven largely by multigenerational Vietnamese families who want a detached casita for aging parents or adult children. That changes the design brief: separate entries, privacy grading, and kitchenettes oriented away from the main house’s patio matter as much as square footage. We’ve built with prefab systems, shed conversions, and custom site-built units across the 92683, 92684, and 92685 ZIP codes. ADU Builders in Westminster covers the full picture, from Tuff Shed conversions to architect-designed modular units.
Bathroom Remodeling in Westminster
Most 1960s Westminster bathrooms are original: cast iron tubs, 4-inch tile, single vanity, and a window that no longer opens. The work usually involves replacing the shower valve, repairing water-damaged subfloor around the toilet, and updating the vent fan to something that actually pulls moisture out. We handle the full remodel, including moving plumbing if the floor plan allows it. Bathroom Remodeling in Westminster has the detailed breakdown of what the job involves and what it costs.

Kitchen Remodeling in Westminster
Kitchen remodeling in Westminster almost always starts with a 1950s to 1970s galley kitchen that feels closed off from the rest of the house. The counter space is limited, the cabinets are particleboard with failing hinges, and the electrical panel is usually maxed out, which matters when you want a dedicated circuit for a new range or microwave. We approach these remodels as a full gut-and-rebuild rather than a surface refresh, because the framing and plumbing behind the walls are usually as tired as the finishes in front of them. Classic ADU Builders handles the whole job, shell to finished interior, including the design, permits, and the finish carpentry. If you want to see how a Westminster kitchen remodel fits into a bigger home project, our Kitchen Remodeling hub page walks through the full process.
Full Galley Kitchen Remodel
Signs you need it
The kitchen still has its original layout, the cabinet doors sag or won’t close, and you can’t open the oven and the dishwasher at the same time.
What it costs in Westminster
A full galley kitchen remodel in Westminster typically runs $55,000 to $85,000 depending on cabinet grade, countertop material, and how much plumbing or electrical needs to move.
How we do it
We demo to the studs, relocate plumbing and electrical as needed, reinforce any load-bearing walls, then install new cabinets, countertops, appliances, and finish with a full backsplash and paint.
Kitchen Cabinet Replacement
Signs you need it
The cabinet boxes are solid but the doors are water-damaged, the laminate is peeling, or the layout wastes the space you have.
What it costs in Westminster
Cabinet replacement in Westminster usually falls between $12,000 and $25,000 depending on linear footage and whether you choose stock, semi-custom, or fully custom boxes.
How we do it
We measure the existing layout, order the new boxes, remove the old cabinets without damaging the drywall, then set and level the new ones and adjust every door and drawer.
Countertop and Backsplash Replacement
Signs you need it
The laminate is peeling at the seams, the tile grout has cracked from settling, or you want a heat-resistant surface for a busy household.

Will a kitchen remodel in Westminster require moving plumbing or electrical?

Most Westminster full-kitchen remodels take six to ten weeks from demo to final walkthrough. Cabinet lead time is usually the biggest variable, so we order materials early and sequence the work around delivery dates. Call (877) 265-5587 for a timeline specific to your project.

What Westminster Customers Say
"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Steve Mercer"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."
— Marcy 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."
— Beatriz Morales
