ADU Company in Westminster, CA
Kitchen remodeling in Westminster, CA usually costs between $28,000 and $65,000 depending on whether you’re refreshing a 1950s ranch original or gutting a poorly permitted addition. Most of the kitchens we open up in this city share the same story: original cabinets, single-wall layouts, and ventilation that was never designed for the way Vietnamese-American families actually cook. Westminster ADU Builders handles the full scope, from first demolition through final cabinet install and countertop seal. Call (833) 620-3521 to schedule a walkthrough.
Why Westminster Homes Are Different
Westminster’s housing stock is overwhelmingly 1950s through 1970s tract construction. Single-story stucco ranch homes on modest lots, many with detached or attached two-car garages and alley access along the rear property line. That layout shapes nearly every kitchen project we take on here. The original kitchens in these homes were built small, often 80 to 120 square feet, with a single window over the sink and a door leading to the garage or side yard.
The climate works in your favor for scheduling. Westminster sits in the coastal-inland band of Orange County, so we rarely lose days to rain between May and October. Winters bring occasional storm systems and marine-layer humidity, which matters more for exterior work but can still affect a kitchen that backs up to a poorly flashed exterior wall. More than once we’ve opened a wall during a February remodel and found moisture staining behind the sink base cabinet from years of stucco hairline cracks.
Another Westminster-specific reality: unpermitted additions are common. Homeowners in the 1970s and 1980s enclosed patios or extended kitchens without pulling permits. When you buy one of these homes and start planning a remodel, the first question is always whether the existing square footage was ever approved. We check permit history as a standard first step, because discovering an unpermitted kitchen bump-out mid-project changes scope, schedule, and budget.
Our Main Westminster Services
Kitchen remodeling is the call we get most often, but two other services run close behind for Westminster homeowners. Here’s what each involves locally.
ADU Builders in Westminster
Westminster is one of Southern California’s densest Little Saigon communities, and ADU demand here runs through multigenerational households. Homeowners want a rear-yard unit for aging parents or adult children, which means kitchenettes built for real cooking: strong ventilation, gas lines, and surfaces that hold up to daily use. The city’s older tract parcels usually point toward garage conversions rather than ground-up builds, since alley-served rear yards and existing slabs make conversion the more practical path. We walk clients through prefab brands like Abodu and Dvele alongside traditional site-built options, then recommend based on the lot, not the catalog. See how we approach this at ADU Builders in Westminster.
Bathroom Remodeling in Westminster
Bathrooms in Westminster’s 1950s-to-1970s homes are almost universally undersized by current standards. Five-foot-by-eight-foot full baths with single-sink vanities and tub-shower combos are the norm. When we remodel one, the typical scope includes removing the tub for a curbless shower, adding a vent fan that actually exhausts to the outside, and correcting subfloor rot common in these older slabs. For homes adding an ADU, we often remodel the main bath and build the ADU bath in the same permit cycle, keeping the whole project under one contract. Details are at Bathroom Remodeling in Westminster.

Kitchen Remodeling in Westminster
Westminster kitchens in 1950s and 1960s ranch homes run small, dark, and under-ventilated, with original cabinets that have outlived their usefulness and layouts built for a different era of cooking. The moisture from coastal-inland weather and decades of stucco exposure means we routinely find wall damage behind sink bases and range backsplashes once demolition starts. Adding an ADU often pushes homeowners to reconsider the main kitchen at the same time, since the same crew can handle both scopes. For a fuller look at our process, see Kitchen Remodeling.
Galley Kitchen Renovation
Signs you need it
You have one usable counter, appliances stacked against a single wall, and two people cannot stand in the kitchen at the same time without shoulder contact.
What it costs in Westminster
Galley kitchen renovations in Westminster generally run $28,000 to $48,000 depending on cabinet quality, countertop material, and whether we’re moving plumbing or gas lines.
How we do it
We open the wall between kitchen and dining area where structurally possible, relocate the refrigerator to create a proper work triangle, and add a ventilation hood that ducts to the outside.
Full Kitchen Gut and Rebuild
Signs you need it
The layout does not work, the subfloor or wall framing has water damage, and you want to change the kitchen footprint rather than patch what’s there.
What it costs in Westminster
A full gut-and-rebuild in Westminster ranges from $48,000 to $85,000, with most projects landing in the $55,000 to $65,000 range once you factor in new plumbing, electrical, and structural work.
How we do it
We strip the kitchen to studs and slab, replace damaged framing, run new plumbing and electrical, then rebuild with a layout sized for the way your household cooks.

FAQs About ADU Company in Westminster
Most Westminster kitchen projects start within 2 to 4 weeks of the signed contract, depending on permit review time with the city. Plan the walkthrough first, then we’ll give you a written schedule with start and finish dates before you commit. Call (833) 620-3521 to set one up.
Some Westminster neighborhoods have HOAs, mostly in the newer developments rather than the older tract areas. We check your address for any HOA requirements before we start, but kitchen remodels inside the existing footprint rarely trigger HOA review. ADUs do, so we handle that paperwork early.
Yes, and it’s a pattern we see often in Westminster. The same crew handles both scopes under one contract, which means one permit set, one schedule, and no coordination gaps between trades.
