ADU Company in Claremont, CA
Kitchen remodeling in Claremont means working with the 1950s-to-1970s ranch and postwar tract homes that dominate the city, plus a pocket of century-old Craftsman bungalows near the Village. Those kitchens run small, the wiring is original, and the flat lots allow for expansion if you plan the footprint carefully. Holloway ADU Builders has served Claremont since 2016, handling everything from cabinet refacing in a graduate-student rental to full gut renovations in the historic district. If you’re weighing a kitchen project alongside an ADU, we’ll help you sequence both so you’re not paying for the same prep work twice. Call (855) 617-6356 to talk through your lot and your budget.
Why Claremont Homes Are Different
Claremont sits at the foot of the San Gabriel Mountains in the Pomona Valley, and the climate shapes every kitchen decision here. Summer afternoons hit triple digits with intense UV, while winter nights dip into the 30s. That swing means kitchens need ventilation that actually pulls heat out, insulation that holds whatever your HVAC produces, and finishes that won’t warp when the Santa Anas push dry wind through in the fall. For older Claremont homes, the classic original kitchen is a closed-off galley running along the back wall, usually 80 to 120 square feet, with a single window over the sink. The housing stock around the Claremont Colleges and the Village includes 1900s and 1920s Craftsman bungalows where any kitchen change can trigger historic-district review, so we plan around those limitations rather than finding out at the permit counter.
The flat lots north of Foothill Boulevard and south of the 210 generally make rear and side additions straightforward. But the four-set submittal reality applies: site, architectural, structural, and energy drawings all need to be signed and consistent before the City will take a single review round. That’s true whether the project is a kitchen bump-out, a full ADU, or both under one permit. We keep our drawings tight so your plan check doesn’t stall.
Our Main Claremont Services
Most Claremont homeowners call us about one of two things: building an ADU from scratch or remodeling a bathroom that’s past its useful life, often in the same phone call as a kitchen question. Here’s what each involves here.
ADU Builders in Claremont
Claremont’s AB 1033 condo-ization pathway is unusually active, and that changes how we approach ADU design here. Because buyers can now purchase a detached unit separately, homeowners near the nationally ranked Claremont Unified School District often want the ADU to function as a standalone family-sized home rather than a rental afterthought. That means full kitchens, proper bedrooms, and exterior character that matches the existing ranch or Craftsman roof lines. We’re brand-agnostic, working with manufacturers including Cover and Dvele, plus site-built and Tuff Shed conversion options, so the method matches the lot rather than the other way around. ADU Builders in Claremont covers the full scope.
Bathroom Remodeling in Claremont
The classic Claremont postwar bathroom is a 5-by-8 three-piece with original cast-iron plumbing and a single exhaust fan that has never once cleared the steam. In a rental-heavy college town, that means mold, warped door frames, and tenants who complain. We open up these bathrooms with curbless showers where we can, add real ventilation rated for the square footage, and spec finishes that survive the dry-summer heat without cracking. When an ADU is part of the plan, we sequence the plumbing rough-in so both structures share the work efficiently. Bathroom Remodeling in Claremont walks through pricing and scope.

Kitchen Remodeling in Claremont
A Claremont kitchen remodel usually means opening a closed-off galley in a 1,400-to-2,400-square-foot ranch, rerouting plumbing that dates to the Eisenhower administration, and adding real ventilation that handles triple-digit summer afternoons. The goal is almost always the same: a kitchen that stays cool while cooking, holds up to dry Santa Ana air, and fits the architectural character of the neighborhood, whether that’s a modest postwar tract or a Craftsman near the Village. We handle the full scope, from structural work through tile and cabinetry, so you’re not hiring a second contractor for the finish. Holloway ADU Builders is an Kitchen Remodeling specialist first, and an ADU company second, because the kitchen is usually the most-used room in the house and the hardest to get right.
Galley Kitchen Expansion
Signs you need it
The kitchen is a single narrow corridor, usually under 100 square feet, where two people cannot pass and there is no space for a table.
What it costs in Claremont
Galley expansions in Claremont typically run $45,000 to $80,000 depending on how far the exterior wall moves and whether the existing slab needs work.
How we do it
We open the back wall, pour or extend the foundation to match the flat Claremont lot grade, reframe the roof to keep the original eave line, then run new electrical, plumbing, and insulation before drywall and finishes.
Full Kitchen Renovation
Signs you need it
Cabinets are delaminating, the layout wastes a third of the floor space, and the single window over the sink leaves the rest of the room dark through most of the afternoon.
What it costs in Claremont
Full kitchen renovations in Claremont, including new cabinetry, countertops, flooring, and appliances, range from $65,000 to $120,000 for the typical ranch home.
How we do it
We start with measured drawings, then demo to studs, update all rough utilities, insulate to exceed Claremont’s Title 24 baseline, install low-E windows where the opening allows, and finish with casework and tile that suit the home’s era.
What Kitchen Remodeling Costs in Claremont
These ranges reflect what we see across the 91711 zip code, from modest postwar tracts to Craftsman restorations near the colleges.
| Item | Typical range in Claremont |
|---|---|
| Galley kitchen expansion | $45,000 – $80,000 |
| Full kitchen renovation | $65,000 – $120,000 |
| Cabinet refacing and countertop replacement | $18,000 – $35,000 |
Two things push Claremont kitchen costs higher than neighboring cities. First, the older Craftsman and ranch homes near the Village often have original electrical panels that need replacement before any kitchen permits will clear. Second, historic-district review adds design time when the home falls within the protected zone.
How long does a kitchen remodel take in Claremont?
Most Claremont kitchen remodels run 8 to 14 weeks from the first day of demo to final inspection. Permit review alone can take 4 to 6 weeks if the home is in a historic district, so we encourage homeowners to start the drawings early.
Will you handle the permits for a Claremont kitchen remodel?
Yes. We prepare the full plan set and pull permits with the City of Claremont, which requires site, architectural, structural, and energy drawings to be signed and consistent before the single review round begins. Call (855) 617-6356 for a free estimate on your project.
Brands We Service in Claremont
We work with leading prefab and modular ADU brands including Cover, Dvele, and Mighty Buildings, and we spec James Hardie fiber cement exteriors on many Claremont projects because the material handles Pomona Valley heat and UV without the maintenance that wood demands. Cabinetry, fixtures, and finish materials are ordered through our local supplier network in the Inland Empire, which keeps lead times predictable. For details on the full line card, see our brands.

In Claremont, the historic-district homes near the Village tend to land at the higher end of every range because design review and character-matching materials add cost. Steep hillside lots on the north edge of town near the foothills also push costs up when fire-hardened materials and longer foundation runs are required. We price everything with a written line-item quote before work starts, and the number we agree on is the number you pay.

What Claremont 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
