ADU Company in Westminster, CA
Kitchen remodeling in Westminster often means working inside a 1950s or 1960s ranch with a closed-off galley layout, low ceilings, and a floor plan that fights the way families actually live here. Holloway ADU Builders has served Westminster since 2016, and we’ve remodeled enough of these homes to know the structural and code realities behind the walls before the first cabinet comes out. We also build ADUs across the city’s 92683, 92684, and 92685 ZIP codes, often pairing a kitchen remodel with a rear-unit build so the whole lot works as one property. Call (855) 617-6356 when you’re ready to talk through your options.
Why Westminster Homes Are Different
Westminster’s housing stock runs heavily to 1950s through 1970s single-story tract homes on tight lots, many built with attached garages and rear alley access. That geometry matters. A kitchen in these homes is usually a long, narrow galley tucked against the garage wall, with plumbing on an interior wall and little natural light. Remodeling those spaces means working around load-bearing posts, cast-iron drain lines that may date to the Eisenhower administration, and floor joists that weren’t designed for modern appliance weights.
The climate helps. Westminster sits in Orange County’s coastal-inland band, so homes don’t carry heavy heating or cooling loads, but the strong afternoon sun and occasional Santa Ana heat events push homeowners toward cross-ventilation, lighter finishes, and window placement that keeps the kitchen usable without cranking AC. Because so much of the city falls within the 92683 core of Little Saigon, kitchen work frequently includes culturally specific requests: higher-BTU gas ranges, dedicated prep zones, ventilation strong enough for long-simmered broths, and layouts that let two or three generations cook side by side. Those aren’t afterthoughts here; they’re standard scope on a Westminster remodel.
The other big variable is lot coverage. Most Westminster parcels are already near maxed-out coverage, so any kitchen addition or bump-out needs careful setback math. When we pair a kitchen remodel with an ADU, we sequence the site work so one permit package covers both where the city allows it. That sequencing saves clients real time and avoids redoing trenching or utility drops.
Our Main Westminster Services
Most Westminster homeowners call us first about one of two projects: building an ADU or remodeling an existing bathroom. Both jobs run into the same local conditions, but the scopes are different enough that each gets its own page.
ADU Builders in Westminster
Westminster’s lot pattern, with those rear alleys and detached garages, makes it one of the more ADU-friendly cities in Orange County. We handle the full build path here: garage conversions, rear-detached units, and prefab or modular placements where the alley access allows a clean crane or panel drop. Because many of these lots sit near max lot coverage, we spend real time on siting and setback strategy before any deposit changes hands. For homeowners still deciding between a site-built ADU, a prefab unit, or a Tuff Shed conversion, we walk through the trade-offs in plain language. Full detail is on our ADU Builders in Westminster page.
Bathroom Remodeling in Westminster
Bathrooms in Westminster’s older tract homes are typically 5 feet by 8 feet, sitting on slab foundations with copper supply lines and cast-iron drains. Remodeling them well usually means moving or replacing the drain, waterproofing the wet wall correctly, and solving ventilation problems in bathrooms that were originally built with a single small window. We also finish ADU bathrooms, which means our team can carry the same waterproofing standards from a main-house remodel into a new rear unit without a second contractor.

Kitchen Remodeling in Westminster
Kitchen remodeling in Westminster runs about $35,000 to $85,000 for a full-gut job in these 1950s – 1970s tract homes, with simpler refreshes starting lower and larger reconfigurations exceeding that range when walls move. Most of the kitchens we see in the 92683 core are original or near-original: cramped galleys, laminate counters, and cooktops wedged against the garage wall with no ventilation to speak of. The real cost drivers here are foundation work when drains need relocating, load-bearing wall alterations, and the state of the electrical panel, which on many Westminster homes is a 100-amp unit that predates modern appliance loads. We’ve written a full Kitchen Remodeling guide for the broader service, but the specifics below apply to Westminster homes.
Full Galley Remodel
The single most common Westminster kitchen job: opening a narrow galley and rebuilding it without moving exterior walls.
Signs you need it
The kitchen is under 100 square feet, has one usable counter, and forces two cooks to pass sideways.
What it costs in Westminster
Expect $38,000 to $55,000 depending on cabinet grade, countertop material, and whether the plumbing stays in its current wall.
How we do it
We demo to studs, reframe any rotted areas, replace the drain and supply lines, then rebuild with new cabinets, counters, backsplash, and a properly vented range hood.
Kitchen Bump-Out Addition
For homeowners willing to trade yard space for a larger kitchen, this job extends the footprint into the rear or side yard.
Signs you need it
The lot has usable side or rear yard space and the existing kitchen cannot be reconfigured into a functional triangle without new square footage.
What it costs in Westminster
Plan on $65,000 to $85,000 once foundation, framing, roofing, and the kitchen itself are combined, with permits pulled through the City of Westminster.
How we do it
We check lot coverage and setback limits first, then pour a matched foundation, frame the addition, tie the roof into the existing plane, and finish the interior as one continuous kitchen.
What Kitchen Remodeling Costs in Westminster
| Item | Typical range in Westminster |
|---|---|
| Cabinet replacement (full kitchen) | $12,000 – $24,000 |
| Countertop replacement | $4,000 – $9,000 |
| Full galley remodel | $38,000 – $55,000 |

Prices in Westminster bump upward when we find cast-iron drains that need full replacement, when a load-bearing wall comes out and a beam goes in, or when the electrical panel needs an upgrade to support induction cooktops and double ovens. Our written quotes are fixed once we’ve opened the walls or completed a thorough site inspection, so the number doesn’t drift on you mid-job.
Can you remodel a Westminster kitchen without moving the plumbing?
Yes, and that’s the most cost-effective path. Keeping the sink, dishwasher, and range in their current positions saves $3,000 to $7,000 in drain and supply line relocation. Call (855) 617-6356 for an exact figure on your layout.
How long does a full kitchen remodel take in Westminster?
Most full-gut Westminster kitchens run six to ten weeks from demo to final inspection, depending on whether cabinets are in stock and whether the city inspector’s schedule holds. A bump-out adds two to three weeks for foundation and framing.

We work with a range of ADU and material brands across Westminster projects, including our brands like Abodu, Cover, and Dvele for prefab and modular units, plus James Hardie fiber cement exteriors for weather-resistant cladding.

FAQs About ADU Company in Westminster
Yes. We pull permits through the City of Westminster for kitchen remodels, bath remodels, and ADU builds. That includes all plan submittals, inspection scheduling, and any required lot coverage or parking documentation. Call (855) 617-6356 if you want to understand what your specific project requires.
For kitchen and bath remodels, we typically start within two to four weeks of a signed contract, depending on material lead times and the city’s current plan review queue. ADU projects usually take longer because of the design and permitting stage, so we tell clients to expect a six to twelve week pre-construction window on most Westminster lots.
Some Westminster neighborhoods have HOAs, especially newer subdivisions in the 92684 and 92685 ZIP codes, and those associations may require design review before construction starts. We prepare the documentation HOAs typically request, including elevation drawings and material specifications, and we coordinate submission alongside the city permit process.

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."
— Heather Reed"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
