ADU Company in Claremont, CA

Kitchen remodeling in Claremont means working with homes built mostly between 1950 and 1980, where original layouts have small, closed-off kitchens and plumbing that hasn’t moved in fifty years. The hot, dry eastern San Gabriel Valley summers make ventilation and cooling choices matter more here than in coastal cities. Casita ADU Builders handles full kitchen remodels with the same ADU-only focus we bring to every project, from removing a load-bearing wall to matching the mid-century character of a Claremont ranch. Call (877) 658-7475 to schedule a free estimate for your kitchen remodel.

Why Claremont Homes Are Different

Claremont’s housing stock is dominated by post-WWII tract and custom ranch homes from the 1950s through the 1970s. Many of these houses in the 91711 ZIP still have their original floor plans, which means narrow galley kitchens, disconnected dining rooms, and wiring that predates modern appliance loads. That’s a very different starting point than a newer home in a master-planned community fifteen miles east.

The city’s identity as a college town adds another layer. Homes near the Claremont Colleges, especially around the Village area, fall under historic preservation and design-review guidelines that don’t apply in neighboring cities. A kitchen remodel that opens a wall or changes a window line can trigger extra design review to keep the exterior compatible with neighborhood character. We plan for that from the first site visit, so permit timing doesn’t surprise you mid-project.

And the climate is real. Claremont sits far enough inland that summer heat waves routinely push temperatures into the high 90s and beyond. Kitchens here need range hoods that actually move hot air out, insulation that holds up through August, and window treatments that don’t turn the room into a greenhouse by 3 p.m. Those aren’t afterthoughts for us. They’re part of how we spec every Claremont job.

Our Main Claremont Services

Claremont homeowners call us most often about two things: building an ADU on a deep backyard lot, and bringing a 1950s or 1960s bathroom up to modern standard. Both jobs require knowing how this city’s design-review process works and how to work with the existing mid-century bones of the house rather than against them.

ADU Builders in Claremont

Claremont’s large inventory of mid-century ranch homes on generous lots makes it one of the more ADU-friendly cities in the eastern San Gabriel Valley. Detached ADUs can often be tucked behind an existing house without touching the street-facing character the city’s design guidelines protect. Garage conversions are also common, since many Claremont homes still have detached garages that sit unused or underused. We work across prefab manufacturers like Abodu and Cover, plus Tuff Shed conversions, and finish interiors with our own kitchen and bath teams. Learn more about ADU Builders in Claremont.

Bathroom Remodeling in Claremont

Most Claremont bathrooms were built when a single vanity and a tub-shower combo were the standard, and they show it. Tight door clearances, cast-iron plumbing nearing the end of its service life, and a lack of ventilation are common across the 91711 ZIP. Our in-house bathroom team handles everything from a straightforward tub-to-walk-in-shower conversion to a full gut remodel with new subfloor and plumbing. We handle the permit path through Claremont’s building department, which keeps the job moving. See Bathroom Remodeling in Claremont for specifics on what a Claremont bathroom job involves.

Kitchen Remodeling in Claremont

Kitchen remodeling in Claremont is usually about fixing a layout that made sense in 1962 and doesn’t anymore. The houses in this city were built when kitchens were closed-off service areas, not the open, connected hub that buyers and families now expect. You get a galley kitchen with one window, a wall separating it from the dining room, and not enough counter space for two people to work at once. On top of that, Claremont’s hot summers mean a poorly ventilated kitchen becomes the hottest room in the house from June through September. Our job is to open the space, modernize the mechanicals, and build something that respects the home’s mid-century character while functioning like a new build. We finish every detail in-house, so there’s no handoff to a second contractor for counters, fixtures, or cabinetry. If you’re comparing options, our Kitchen Remodeling overview page walks through the full scope of what we do.

Wall Removal and Open-Concept Layouts

Signs you need it

The kitchen is isolated from the dining or living area, and the only way to seat more than two people is in another room entirely.

What it costs in Claremont

Wall removal with structural work in a mid-century Claremont ranch typically runs $3,500 to $8,500 depending on whether the wall is load-bearing and how much mechanical rerouting is involved.

How we do it

We assess the wall’s structural role, size the beam or header, handle the permit plans, remove the wall, and patch floors and ceilings so the transition is clean.

Full Kitchen Renovation with Modern Finishes

Signs you need it

Cabinets are original or worn, countertops are cracked or dated, and appliances are reaching the end of their life.

What it costs in Claremont

A full kitchen renovation in Claremont with new cabinetry, counters, and flooring typically ranges from $25,000 to $50,000 depending on size and material choices.

How we do it

We demo the old kitchen, update plumbing and electrical to current code, install new cabinets, counters, flooring, and fixtures, then handle finish carpentry and paint.

What Kitchen Remodeling Costs in Claremont

Item Typical range in Claremont
Wall removal (structural) $3,500 – $8,500
Full kitchen renovation $25,000 – $50,000
Cabinet refacing or replacement $8,000 – $18,000

Will a kitchen remodel in Claremont require design review?

If your home is in the Village area or a historic district near the Claremont Colleges, exterior changes like window size or placement can trigger design review. Interior-only remodels typically don’t. Call (877) 658-7475 for an exact quote, estimates are free.

How long does a kitchen remodel take in Claremont?

Most Claremont kitchen remodels run four to eight weeks from demo to final walkthrough, depending on structural work and whether permit review adds time. We give you a written schedule before work starts and stick to it. Call (877) 658-7475 to ask about timing for your specific home.

What Claremont Customers Say

★★★★★ 4.8 from 4+ reviews

"Knew the local setback and parking rules cold, which saved us from designing something that would never have been approved."

— Maria Martinez

"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."

— Arjun Singh

"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."

— Robert Gallagher
