ADU Company in Claremont — Design, Permits and Build Under One Contract

ADU Company in Claremont, CA

Kitchen remodeling in Claremont is shaped by the city’s older housing stock: 1920s bungalows and mid-century ranch homes where original layouts were built for a different era. Most Claremont kitchens we see in the Village, the college neighborhoods, and Claremont Hills were designed before open-concept living, island seating, or modern appliance footprints existed. That means the work often involves removing load-bearing walls, upgrading electrical panels from 100-amp to 200-amp service, and replacing galvanized plumbing that has been in the ground since the Eisenhower administration. We handle the full renovation in-house, from layout to finishes, so you never coordinate multiple contractors. Call (866) 538-0916 to talk through your Claremont kitchen.

Why Claremont Homes Are Different

Claremont sits at the base of the San Gabriel Mountains in the Inland Empire, which means real summer heat and regular Santa Ana wind events that coastal cities never feel. A kitchen remodel here needs serious ventilation design: range hoods sized for actual airflow, not just code minimums, and window placements that don’t turn the room into a solar oven by 2 p.m. The housing stock runs heavily toward pre-war California bungalows, Spanish and Mediterranean revival cottages, and ranch homes from the 1950s and 1960s. Those homes have real character, but they also carry old service panels, undersized gas lines, and floor joists that don’t always meet current deflection standards for stone or tile.

Claremont’s design review culture matters too. The Village and several historic districts around the colleges enforce standards that fall well beyond state minimums for ADUs and major remodels. If your home is in a historic district or near a designated landmark, expect a level of architectural scrutiny you won’t find in neighboring Upland or Montclair. We plan for that from the first site visit, not after the permit is submitted. The large lots that make Claremont so livable also mean kitchens often connect directly to backyard spaces, which changes how we think about sightlines, door swings, and indoor-outdoor flow. It’s a different design conversation than a tract home in Rancho Cucamonga, and we treat it that way.

Our Main Claremont Services

Claremont homeowners reach out to us for two projects more than any others, and both draw on the same core strength: we build the structure and finish the interior without handing you off to a second contractor.

ADU Builders in Claremont

Detached backyard ADUs are the dominant model in Claremont, because the older single-story homes sit on generous lots that can absorb a new unit without disturbing the main house. Most of our Claremont clients are planning for a returning graduate student, a live-in grandparent, or a professor on sabbatical rather than a short-term rental, which shifts the design toward kitchens with real storage, quiet HVAC, and materials that age well. We match you across prefab manufacturers like Abodu, Dvele, and Boxabl, or we go site-built where the lot, setbacks, or historic-district review call for it.

Bathroom Remodeling in Claremont

Older Claremont homes often have a single bathroom with the original cast-iron tub, a 60-amp-era wall heater, and tile set in mud that has cracked over decades. We rebuild these spaces with modern waterproofing, ventilation that handles the Inland Empire heat, and layouts that work for multigenerational living, a common need when an ADU goes into the backyard and the main house bath becomes the guest bath. We handle the full scope in-house so the plumbing, tile, and fixtures are one coordinated package. See how we approach Bathroom Remodeling in Claremont.

Kitchen Remodeling in Claremont

Kitchen remodeling in Claremont usually means working inside a home built between the 1920s and the 1960s, where the original kitchen was designed as a closed-off utility room, not the social center of the house. We open those walls, correct decades of deferred electrical and plumbing work, and rebuild the room to handle the Inland Empire heat: ventilation that moves real air, refrigeration placement away from west-facing windows, and finishes that hold up to dry heat and Santa Ana dust. Our kitchen work pairs directly with our ADU builds, because every detached unit needs a full kitchen, and we finish that interior through Kitchen Remodeling in-house rather than sending you to a separate contractor.

Full Kitchen Renovation

Signs you need it

Your Claremont kitchen has original 1950s wiring that trips when the toaster and microwave run together, the layout traps two people in a dead-end corner, or the cabinet boxes have water damage from a leak that predates your ownership.

What it costs in Claremont

A full kitchen renovation in Claremont typically runs $45,000 to $85,000 depending on structural changes, panel upgrades, and finish selection.

How we do it

We start with a site visit to map load paths and existing utilities, then produce a fixed-price line-item scope, pull permits, complete the rough electrical and plumbing, install cabinets and counters, and finish with backsplash, fixtures, and final inspection.

Kitchen Island Addition

Signs you need it

Your family gathers in the kitchen during holidays but everyone stands around the perimeter because there is no central work surface or seating zone.

What it costs in Claremont

Adding an island with seating and power to a Claremont kitchen typically costs $8,000 to $18,000, more if plumbing for a sink or cooktop is required.

How we do it

We confirm floor-joist capacity below the island location, run new electrical through the crawlspace or slab, frame and finish the island, and match the countertop and cabinet style to your existing kitchen.

Cabinet Refacing and Countertop Replacement

Signs you need it

Your cabinet boxes are structurally sound but the doors are delaminating, the hinges sag, and the tile countertop has grout that no longer seals or cleans properly.

What it costs in Claremont

Cabinet refacing with new doors, hardware, and a quartz or stone countertop in Claremont typically runs $12,000 to $28,000.

How we do it

We refinish or replace door and drawer fronts, install soft-close hardware, set the new countertop slab, and reconnect the sink and fixtures with new shutoff valves and supply lines.

What Kitchen Remodeling Costs in Claremont

Panels, gas-line relocation, and structural work push kitchen remodels toward the upper end in Claremont, especially in pre-war homes with knob-and-tube remnants and cast-iron drain lines. Our quotes are fixed and line-itemed before work starts, so the number we show you is the number you pay unless you change scope mid-project.

How long does a kitchen remodel take in Claremont?

Most full kitchen remodels in Claremont take 6 to 10 weeks from demo to final inspection, with cabinet refacing running 1 to 2 weeks. Permit review in Claremont can add time, especially in historic districts, and we factor that into the schedule before we start.

Will my Claremont kitchen remodel require a panel upgrade?

Many 1920s to 1960s Claremont homes have 100-amp panels that cannot support modern appliance loads plus a new ADU on the property. We identify whether a 200-amp upgrade is required during the estimate visit, not after demo starts. Call (866) 538-0916 for a fixed, line-itemed quote.
