ADU Company in Claremont, CA
Kitchen remodeling in Claremont usually means working inside a 1920s Spanish cottage or a mid-century ranch with mature landscaping right outside the window. Sunstone ADU Builders handles the full scope, from reconfiguring a galley kitchen in the Village-adjacent Historic Core to finishing a brand-new ADU kitchen that matches the main house. We’ve served Claremont since 2011, and the work here consistently comes down to respecting older bones while delivering a kitchen that handles real heat, daily use, and resale expectations. Call (855) 949-1913 for a free estimate.
Why Claremont Homes Are Different
Claremont’s core is small-lot bungalows and Spanish cottages from the 1920s through the 1950s, mixed with mid-century ranch tracts and larger foothill lots. That means tight rear and side setbacks, mature tree root zones, and architectural detailing that a preservation-minded city reviews carefully, especially near the Historic Core and tree-lined Village streets. The Claremont Colleges keep ZIP 91711 unusually design-conscious: homeowners here know what an ADU should look like, and they expect it to read as an architect’s cottage, not a boxy add-on. Hot, dry inland summers with 100°F-plus days, strong afternoon sun, Santa Ana winds, and occasional winter chill mean ADUs and kitchens need real shading, correctly sized A/C, and drainage planned for rare but heavy rain. Mature street trees and old citrus remnants from Claremont’s orchard past frequently sit exactly where an owner wants to build, so arborist clearance and root-protection plans are a normal front-end step before any excavator shows up.
Our Main Claremont Services
Claremont homeowners most often call us about two projects: adding a detached ADU behind an older home, and remodeling a bathroom inside that same older home. Here’s how each works in this city.
ADU Builders in Claremont
Building an ADU in Claremont means navigating the city’s design review while fitting a new unit into a tight rear setback, often beside a mature tree. We plan around the Historic Core’s village aesthetic and foothill drainage patterns, then build with James Hardie fiber cement siding, prefab or stick-built, whichever suits your lot and timeline. ADU Builders in Claremont covers the full process, from permit package to move-in-ready interior.
Bathroom Remodeling in Claremont
Bathroom remodels in Claremont’s older homes frequently mean correcting decades of deferred maintenance inside a small footprint, often with original plumbing that needs careful updating rather than gut replacement. We plan for hot, dry summers and occasional cold snaps, specifying ventilation and moisture-resistant materials that hold up inland. Bathroom Remodeling in Claremont details our in-house approach to ADU and primary-home bathrooms.

Kitchen Remodeling in Claremont
A kitchen remodel in Claremont is rarely about blowing out walls. It’s about making a 1940s galley or a mid-century ranch kitchen function for how people actually cook now, while respecting the home’s original character and surviving the city’s design review without friction. We handle the full kitchen, from layout and plumbing to Kitchen Remodeling finishes, and we do it as the same contractor building your ADU, so one scope, one contract, one accountable team.
Galley Kitchen Reconfiguration
Signs you need it
You’re cooking sideways in a narrow galley with no landing space, appliance doors that collide, and a refrigerator blocking the only natural light.
What it costs in Claremont
Structural work, rerouted plumbing, and cabinetry in a Claremont galley typically run $24,000 to $52,000 depending on whether walls move and how much electrical needs updating.
How we do it
We survey the existing footprint, design a work-triangle layout that fits the room’s original dimensions, reroute plumbing and electrical as needed, then install cabinetry, countertops, and appliances in sequence so the kitchen stays usable for as long as possible.
ADU Kitchen Build-Out
Signs you need it
The ADU shell is up but the interior is an empty room with stub-outs, and you need a code-compliant, rental-ready kitchen that doesn’t require hiring a second contractor.
What it costs in Claremont
A compact ADU kitchen with cabinets, counters, a sink, and a range typically costs $15,000 to $28,000 in Claremont, with appliance selection moving the number.
How we do it
Our in-house team runs the rough-in, sets the cabinets and countertops, installs the sink and appliances, and finishes with trim and lighting, all under the same contract as the ADU structure.
Countertop and Cabinet Refresh
Signs you need it
The cabinets are solid but the doors are worn, the counters are laminate from the 1980s, and the kitchen feels dated even though the layout works.
What it costs in Claremont
Refacing or refreshing cabinets and replacing countertops in a standard Claremont kitchen runs $8,000 to $18,000 depending on surface material and whether you replace drawers and hardware.
How we do it
We assess the cabinet boxes, advise whether refacing or replacement makes sense for your budget, install the chosen countertop material, and update hardware and lighting so the space feels current without a full gut.

FAQs About ADU Company in Claremont
Yes, we handle the full permit package, including design review and any arborist or root-protection submittals the city requires. Claremont’s preservationist review means having a builder who knows the process is the difference between a smooth approval and a stalled one. Call (855) 949-1913 to discuss your lot.
We recommend based on your site, budget, and timeline, not on what we happen to sell. A tight Historic Core lot might favor a compact prefab unit from Abodu or Cover, while a larger foothill parcel might suit a custom stick-built ADU. You get one builder fluent in both.
Yes, that’s our standard scope. The ADU structure, the kitchen, and the bathroom are all finished in-house under one contract, so you’re not coordinating a second contractor after the shell is up. Call (855) 949-1913 to schedule a free estimate.
