ADU Company in Westminster, CA
Kitchen remodeling in Westminster CA often means reworking a 1950s or 1960s tract home with a closed-off floor plan, original plumbing, and a family that actually cooks. We see this in Little Saigon every week: homeowners want a kitchen built for heavy wok cooking, with venting that moves real air, not a decorative hood. Bungalow ADU Builders handles the full scope, from opening walls to pull permits and finishing cabinets, so you are not coordinating three trades. Call (866) 730-4828 to schedule a free estimate.
Why Westminster Homes Are Different
Westminster’s housing stock came up fast in the post-war boom, mostly between 1955 and 1975. That means slab foundations, small lots, and galley kitchens that were designed for one cook, not the multigenerational households common across 92683, 92684, and 92685. Many homes still have their original single-story footprint, which is exactly why garage conversions and second-story additions are common ADU paths here. In Little Saigon, rear detached garages often sit on alley access, so any ADU plan has to account for utility routing through the alley and parking requirements the city will enforce. The coastal climate is forgiving – we rarely need heavy HVAC – but the marine layer does create moisture in enclosed garages, which is why we insist on proper ventilation and moisture barriers before any conversion finishes. And because many Westminster kitchens serve serious cooks, we plan for higher-CFM venting, dedicated circuit loads for wok induction burners or gas lines, and cabinets that hold commercial-size cookware without sagging.
Our Main Westminster Services
Westminster homeowners call us about two things most often: building an ADU from a rear garage or second-story addition, and remodeling a bathroom in a home that still has its original 1960s-era layout.
ADU Builders in Westminster
ADU work in Westminster usually starts with a detached garage off an alley, which changes how you think about setbacks, parking, and where the water and sewer lines tie in. The mild climate means a well-insulated unit works year round, but city permitting still expects proper moisture barriers on garage slab conversions. This is what we do every day, and we have the details on our ADU Builders in Westminster page.
Bathroom Remodeling in Westminster
Bathrooms in Westminster’s original tract homes are often cramped, with cast iron drain lines that have served since the Eisenhower administration. Remodeling them means addressing waterproofing properly, especially in homes near the coast where the marine layer keeps bathrooms damp longer than inland homes. We handle the full tear out and rebuild. Read the details on our Bathroom Remodeling in Westminster page.

Kitchen Remodeling in Westminster
Kitchen remodeling in Westminster CA often comes down to one thing: the original 1960s galley kitchen cannot keep up with a multigenerational household that cooks daily. We remove the wall that makes the kitchen feel like a hallway, re-route the plumbing and electrical that has been buried for sixty years, and build a kitchen that vents properly, stores real cookware, and adds value to the property. If you are also thinking about an ADU, this is the moment to plan both under one permit strategy. For more on our approach, see Kitchen Remodeling.
Galley Kitchen Open-Up
Signs you need it
You have to shuffle sideways past another person, the kitchen has no sightline to the dining area, or you cook alone while everyone else is in the living room.
What it costs in Westminster
Most Westminster galley kitchen open-ups run between $28,000 and $45,000, depending on whether the wall you remove is load bearing and how much plumbing gets relocated.
How we do it
We start with a structural assessment of the wall, pull the permit, frame the new opening with proper header support, then re-route plumbing and electrical before finishing with cabinets, counters, and flooring.
Heavy-Cooking Kitchen Build-Out
Signs you need it
Your household cooks with a wok or deep-frying frequently, your current vent hood recirculates instead of venting outside, or your cabinets are buckling under the weight of pots and jars.
What it costs in Westminster
A full heavy-cooking kitchen with high-CFM venting, reinforced cabinetry, and dedicated circuits typically lands between $38,000 and $60,000 in Westminster.
How we do it
We size the vent run for actual cooking load, add a dedicated circuit for high-output burners or induction, upgrade cabinet boxes to hold real weight, and finish with surfaces that stand up to daily heat and oil.

Yes, and in Westminster it often makes financial sense to do both under one permit package, especially if the ADU kitchen shares a wall or utility riser with the main house kitchen. We coordinate the full scope with one project manager.

What Westminster Customers Say
"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."
— Alicia Ingram"The kitchenette layout he suggested made better use of the space than the one on our original sketch."
— Kelly Schaefer"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."
— Wade Pruitt
