ADU Company in Westminster, CA
Kitchen remodeling in Westminster usually runs $28,000 to $65,000 for a full gut renovation, while bathroom remodels typically land between $14,000 and $32,000. Those numbers shift depending on whether your home is a 1950s stucco tract house in 92683 or a slightly newer build in 92684 with different plumbing layouts. Fullerton ADU Builders has served Westminster since 2017, and we’ve learned that this city’s older housing stock means most kitchens hide surprises behind the drywall: galvanized pipes, undersized electrical panels, and framing that predates modern code. Call (877) 801-4497 when you’re ready to price your project honestly, because the estimate question is the one that actually matters right now.
Why Westminster Homes Are Different
Westminster is the heart of Orange County’s Little Saigon, and a big share of the remodeling and ADU work here runs through multigenerational Vietnamese families. The pattern we see again and again: a homeowner wants a detached unit for aging parents or adult children on the same lot, and the project starts with an existing rear structure, an oversized garage, or an enclosed patio that was never permitted. That family-compound pattern, plus bilingual permitting communication with City Hall, is the hook that wouldn’t apply in neighboring Fountain Valley or Garden Grove.
Much of the 92683 housing stock is 1950s through 1970s single-story stucco tract homes on generous lots. That’s good news for feasibility: lots are wide enough for a detached rear ADU, and the garages are often big enough to convert. The catch is that many of those old detached garages and rear patios were built without permits. Before Westminster will issue a new ADU permit, we often have to legalize or demolish what’s already there. The climate is mild and rarely freezes, so we don’t overbuild for snow load, but we do pay attention to summer heat gain on small units and drainage for the occasional heavy winter storm. The real Westminster variable is the paperwork trail on the back half of the lot.
Our Main Westminster Services
When Westminster homeowners call us, the conversation is usually about one of two things: adding a rentable or multigenerational ADU to the lot, or bringing an aging bathroom up to standard. Both are covered below.
ADU Builders in Westminster
Most Westminster ADU projects begin with a question about what’s actually legal to keep. Behind many Little Saigon homes you’ll find unpermitted rear additions and patio enclosures from decades of family use, and the city won’t issue a new permit until that’s sorted out. We handle that first: evaluating the existing structure, mapping what can be legalized, and then matching the right build method to the lot. Because we work across both site-built and prefab pathways, we’re not trying to force one product onto a lot that needs something else. ADU Builders in Westminster covers the full process, from feasibility to foundation to final.
Bathroom Remodeling in Westminster
Westminster’s older tract homes tend to have bathrooms that were squeezed into the original floor plan, often with cast iron drain lines and single-circuit electrical runs. When we remodel a bathroom here, we’re usually relocating a wall, replacing the drain stack, or adding a dedicated circuit for a heated floor or a larger vent fan. The mild climate means moisture management is less about freeze damage and more about ventilation in small, windowless second baths. Bathroom Remodeling in Westminster lays out the most common scope we see.

Kitchen Remodeling in Westminster
In Westminster, a kitchen remodel is rarely a surface refresh. The 1950s through 1970s tract homes in 92683 and 92684 were built with small galley kitchens, minimal counter space, and electrical panels that can’t support a modern appliance load. Homeowners come to us because they want to open the kitchen to the dining area, add an island, or rearrange the footprint entirely, and the project almost always means upgrading the panel, rerouting plumbing, and bringing the room up to current code. Our Kitchen Remodeling approach treats the kitchen as a structural project, not a cabinet swap, because that’s what these houses actually need.
Full Kitchen Renovation
Signs you need it
You’re working around a cramped galley layout, the cabinets are delaminating, and the cooktop shares a circuit with the microwave and trips the breaker whenever both run.
What it costs in Westminster
A full kitchen renovation in Westminster typically runs $48,000 to $65,000, depending on whether we’re moving plumbing, relocating walls, or running a new 200-amp service.
How we do it
We start with a plan that fixes the electrical and plumbing first, then strip to studs, reframe for the new layout, run new circuits and pex, and finish with cabinets, counters, and appliances.
Cabinet Refacing and Counters
Signs you need it
Your cabinet boxes are solid but the faces are worn, the hinges sag, and the counters are chipped laminate from the original build.
What it costs in Westminster
Cabinet refacing with new counters in Westminster runs $12,000 to $22,000, with the final number set by whether you choose stone or a manufactured surface.
How we do it
We replace doors, drawer fronts, and hardware, install new counter surfaces, and leave the existing cabinet boxes in place to keep the project to a shorter schedule.
What Kitchen Remodeling Costs in Westminster
| Item | Typical range in Westminster |
|---|---|
| Cabinet refacing and counters | $12,000 – $22,000 |
| Mid-range full remodel | $28,000 – $45,000 |
| High-end full renovation | $48,000 – $65,000 |
What pushes a Westminster kitchen toward the top of the range is unpermitted prior work. If someone enclosed the back porch or moved a sink without permits years ago, the city wants that corrected before we close the permit on your remodel. We quote fixed prices with no change orders after the planning phase, so the number you approve is the number you pay unless you change the scope yourself.
How long does a kitchen remodel take in Westminster?
A full kitchen remodel here typically takes 6 to 10 weeks from demo to final, depending on electrical upgrades and any unpermitted work that needs to be addressed first. Call (877) 801-4497 for a schedule that fits your specific home.
Will the price change once work starts?
Not unless you change the scope. We write fixed line-item quotes after the walls are opened during the planning phase, and we pull permits before we start. Call (877) 801-4497 for an exact quote, estimates are free.
Brands We Service in Westminster
We work directly with Plant Prefab and Abodu for factory-built ADUs, and we’ve built Tuff Shed conversions in Westminster more than once. For exteriors on both ADUs and primary remodels, we specify James Hardie fiber cement because the coastal-inland climate demands low-maintenance cladding that handles moisture and heat without warping. See our brands for the full range of what we support.

In Westminster, two things push price up more than anything else: legalizing or demolishing unpermitted rear structures, and upgrading electrical service to support a second unit. The lots are big, but the utility work on a 1960s panel can add real cost. We give you fixed pricing before work starts, so you know exactly what the project costs before we pull the first permit.

Yes, we pull all city permits and coordinate with any HOA requirements that apply to your tract. Westminster also requires that unpermitted rear structures be addressed before an ADU permit will be issued, and we manage that process directly.
Both. We match the unit to the lot, not the other way around. For Westminster’s wide lots, a detached prefab from a factory partner often fits well, but a garage conversion sometimes makes more sense. We’ll walk you through the tradeoffs at your estimate.

What Westminster 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."
— Greg Reed"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Erin Ziegler"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."
— Tim Padgett
