ADU Company in Claremont, CA
Kitchen remodeling in Claremont usually means working inside a 1920s Craftsman or a 1960s ranch that has never been structurally touched since the day it was built. The cabinets are original, the electrical is a 100-amp panel that was never sized for modern appliances, and the floor plan fights the way families actually cook today. We’re Fullerton ADU Builders, and our kitchen work in Claremont is shaped by that reality: older homes on generous lots, where most of our clients are also weighing an ADU in the back yard and want one contractor who can handle both. Call (877) 801-4497 to talk through your kitchen and your lot.
Why Claremont Homes Are Different
Claremont’s housing stock is dominated by single-story ranch and Craftsman-influenced homes built between the 1920s and 1960s. Many of those homes sit on lots that are deeper than they are wide, with detached garages at the rear of the property. That layout quietly shapes almost every project we take on here: a kitchen remodel often happens in a house where the service panel is decades old and the sewer lateral has never been replaced, and the back yard is being considered for an ADU at the same time. We plan kitchen electrical and plumbing around a future back-lot unit rather than having to tear into the wall twice.
The climate is the second big variable. Claremont sits in the inland San Gabriel Valley, where summer temperatures routinely reach 95 to 100°F and winter brings dry Santa Ana winds off the foothills. That matters for kitchen work in two ways: ventilation and cooling have to be sized for real heat loads, and exterior-adjacent kitchen walls benefit from materials that hold up to intense sun exposure and dry conditions. We also see older homes here with galvanized supply lines that have corroded from decades of hard water, which changes the plumbing scope the moment we open a wall. None of this is exotic; it is just the difference between a bid built for Claremont and a bid built for anywhere.
Our Main Claremont Services
Claremont homeowners most often call us about two things: building an ADU on a back lot, and remodeling a bathroom in a house that predates modern plumbing expectations. Both are covered below.
ADU Builders in Claremont
Claremont’s ADU market is shaped by the Claremont Colleges and the steady demand for student and faculty rental housing in the Village-adjacent neighborhoods. Most projects here are detached units tucked behind existing single-story homes, and the city’s Heritage Tree and street-tree ordinances often dictate exactly where a unit can sit, what it can shade, and how the foundation must avoid root zones. We have worked with seven prefab manufacturers including Abodu, Cover, and Dvele, and we match the unit to the lot rather than pushing one product on every property. For the complete Claremont-specific breakdown, see ADU Builders in Claremont.

Bathroom Remodeling in Claremont
Bathrooms in Claremont’s older homes are often the original 5-by-8 alcoves with cast-iron drain stacks that have been doing their job since the Eisenhower administration. We regularly find floor framing that has been compromised by decades of slow leaks around the tub, and tile set on mortar beds that have cracked through. A bathroom project here usually turns into a subfloor repair plus a rough-in replacement, not a cosmetic swap. Our Bathroom Remodeling in Claremont page covers the full scope, timelines, and local cost picture.

Kitchen Remodeling in Claremont
Kitchen remodeling in Claremont tends to be a floor-plan correction more than a finish update. The original kitchens in these 1920s-to-1960s homes were built for a different era: single-wall or galley layouts, no island, no vented range hood, and no space for two people to work at once. Homeowners here are also dealing with the local reality that a kitchen remodel is often step one of a larger property strategy, because the same electrical panel and sewer lateral that limit a kitchen also limit a future ADU in the back. For a full look at how we approach the trade, see Kitchen Remodeling.
Full Kitchen Renovation
Signs you need it
The layout no longer works for the way you cook, the cabinets are failing at the hinges or shelves, and the plumbing and electrical are original to the home.
What it costs in Claremont
A full kitchen renovation in Claremont typically runs $45,000 to $75,000 depending on cabinet grade, appliance selection, and the condition of the rough framing and subfloor we uncover.
How we do it
We start with load-bearing wall verification and a mechanical and plumbing audit, then rebuild the space in sequence: demolition, rough electrical and plumbing, drywall, flooring, cabinet installation, countertops, backsplash, appliance hookup.
Kitchen Facelift
Signs you need it
The layout works, but the doors, drawer fronts, countertops, sink, fixtures, and lighting are worn, dated, or failing.
What it costs in Claremont
A kitchen facelift in Claremont typically runs $18,000 to $35,000 and includes refacing or replacing cabinet fronts, new counters, a new sink and faucet, updated lighting, and a tile backsplash.
How we do it
We keep the cabinet boxes in place where they are structurally sound, swap the visible surfaces and hardware, and replace only the plumbing and lighting fixtures that need it.
What Kitchen Remodeling Costs in Claremont
| Item | Typical range in Claremont |
|---|---|
| Full kitchen renovation | $45,000 – $75,000 |
| Kitchen facelift | $18,000 – $35,000 |
| Cabinet refacing | $8,000 – $15,000 |
What pushes a Claremont kitchen remodel toward the higher end is usually the age of what is behind the walls: galvanized supply lines that need replacing, an undersized 100-amp panel that cannot support an induction range, or a cast-iron drain line under the slab that has to be sleeved. We write a fixed, line-item quote before work starts so the number does not drift once demolition begins.
How long does a kitchen remodel take in Claremont?
Most full kitchen renovations in Claremont take 6 to 10 weeks from demolition to final walkthrough. A facelift is typically 2 to 4 weeks. Permitting with the City of Claremont usually adds 2 to 4 weeks before we can start. Call (877) 801-4497 to schedule your free estimate.
Do I need a permit to remodel my kitchen in Claremont?
Yes, if you are moving plumbing, altering electrical, or removing a wall, the City of Claremont requires a permit. We pull all permits and schedule inspections for you. Cosmetic work like painting and replacing a faucet typically does not require one. Call (877) 801-4497 for specifics on your project.
Brands We Service in Claremont
Our Claremont kitchen and ADU projects routinely include products from James Hardie for exterior cladding and weather-resistant detailing, and prefab structures from Abodu and Cover. Parts for these brands are available on standard Southern California lead times, and we field-measure before ordering so there is no wait on a back-ordered panel or trim piece.

FAQs About ADU Company in Claremont
Yes. We have served Claremont since 2017, with kitchen remodels, bathroom remodels, and ADU construction across the 91711 ZIP code. Our full-time crews are based in Fullerton, about 25 miles southwest, and Claremont is a routine service area rather than an outlier we squeeze in. Call (877) 801-4497 for a free estimate.
For an ADU, yes, and it is the first thing we check. Claremont’s Heritage Tree and street-tree ordinances can restrict where a unit sits and where a foundation trench runs, especially around mature oaks and camphor trees. A kitchen remodel inside the existing home footprint is rarely affected, but we flag any tree issue early so your permit is not held up. Call (877) 801-4497 and we will review your lot.
Yes, and for Claremont homeowners it is often the most cost-efficient path. We plan the house’s electrical panel, sewer lateral, and plumbing capacity once, for both projects, so you are not paying to open the same ground twice. That single-coordination approach is the main reason homeowners here bundle the work. Call (877) 801-4497 to schedule a walkthrough.

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."
— 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
