ADU Company in Rancho Cucamonga, CA

Kitchen remodeling in Rancho Cucamonga usually means opening up a 1970s or 1980s tract home kitchen that was built for a different era – lower ceilings, a closed-off floor plan, and cabinetry that’s lived through four decades of Inland Empire heat. We handle the remodel as a full update: layout, cabinets, counters, lighting, and the wiring and plumbing that older Rancho Cucamonga homes frequently need brought to current code. If you’re planning an ADU at the same time, we can run both projects as one coordinated job, sharing the design review, the permitting, and the crew scheduling instead of juggling two contractors. Call (866) 730-4828 to talk through your kitchen and ADU plans.

Why Rancho Cucamonga Homes Are Different

Rancho Cucamonga is a master-planned, largely built-out suburb, and that changes how remodels and ADUs get designed here. Most of the housing stock dates from the 1970s through the 1990s, with a pocket of 2000s infill, and the typical home is slab-on-grade with stucco exteriors and tile roofs. Slab foundations matter for a kitchen remodel because moving a sink, adding a gas line, or relocating a drain means cutting into concrete rather than running pipe through a crawl space. In summer, temperatures routinely exceed 100°F, so any kitchen or ADU addition has to be planned around oversized cooling capacity, deep overhangs, and window orientation that doesn’t turn the room into a solar oven.

The other layer here is HOA and city design review. Rancho Cucamonga’s planning process is more involved than in unincorporated parts of the county, and many subdivisions have architectural committees that must sign off before a permit is even submitted. For the foothill neighborhoods, Santa Ana winds and local fire-zone maps can trigger wildfire-resistant construction requirements – exterior materials, vent screens, and eave details that tract builders never had to think about. Cul-de-sac frontage and backyard privacy are part of the city’s character, so we site projects to preserve both rather than maximizing square footage at the expense of the lot.

Our Main Rancho Cucamonga Services

Rancho Cucamonga homeowners call us most about two things: building an ADU on a lot that already has a house on it, and bringing a dated bathroom up to something worth living with. Here’s how each one works here.

ADU Builders in Rancho Cucamonga

An ADU in Rancho Cucamonga is usually a detached unit in the rear yard of a 1970s to 1990s tract lot, and the hard part is rarely the structure itself – it’s fitting a livable unit into a yard that’s already holding a pool, a patio, and mature landscaping. We walk the lot, check the HOA covenants, measure the actual usable setback area, and then match your budget to the right system, whether that’s a panelized build from Abodu or a modular line like Dvele. From foundation to finished kitchen, one team handles the whole scope instead of handing you between a shell contractor and a finish crew. See how the full process works on our ADU Builders in Rancho Cucamonga page.

Bathroom Remodeling in Rancho Cucamonga

Bathrooms in Rancho Cucamonga’s housing stock tend to be tight – typical master baths from the 80s and 90s run 40 to 60 square feet, and the guest baths are even smaller. Remodeling here usually means reconfiguring a five-foot-wide space to actually function, reworking the ventilation for Inland Empire humidity, and sometimes moving a toilet flange off a slab floor that’s been patched once already. We bring the same in-house crew that handles our ADU interiors, so the tile, the vanity, the shower glass, and the fixtures all get finished by the same people who started the job. Details are on our Bathroom Remodeling in Rancho Cucamonga page.

Kitchen Remodeling in Rancho Cucamonga

Kitchen remodeling in Rancho Cucamonga frequently means taking a 1970s or 1980s tract kitchen – closed off from the living area, built on a slab, starved for counter space – and turning it into a room that works for how families actually cook and gather now. The climate adds its own requirement: a Rancho Cucamonga kitchen needs ventilation and cooling that can keep up with 100-plus-degree summer days, not just a builder-grade range hood and a single ceiling light. We scope the full kitchen remodel as one integrated project: layout, cabinetry, counters, fixtures, lighting, and the plumbing and electrical work those older homes need brought current. If you’re pairing the kitchen with an ADU on the same property, we can coordinate both scopes under one permit package and one project manager. For a deeper look at the service, see our Kitchen Remodeling page.

Cabinet Replacement and Layout Changes

Signs you need it

Your cabinet boxes are delaminating from decades of heat, doors won’t stay aligned, or the layout walls off the kitchen from the rest of the house.

What it costs in Rancho Cucamonga

Cabinet replacement and layout changes in Rancho Cucamonga typically run $18,000 to $40,000 depending on cabinet grade, layout complexity, and whether walls come down.

How we do it

We measure the existing footprint, draw the new layout, order cabinets to fit the specific wall lengths, and handle the demo, drywall patching, and reinstallation as one scope – including relocating plumbing or electrical on the slab where the new layout calls for it.

Countertop and Backsplash Upgrades

Signs you need it

Your existing counters are chipped laminate or dated tile, and the backsplash grout has cracked or stained past the point of cleaning.

What it costs in Rancho Cucamonga

Countertop and backsplash upgrades in Rancho Cucamonga fall between $6,000 and $15,000 for typical kitchen sizes, with quartz and natural stone at the upper end.

How we do it

We template the counters after the cabinets are set, fabricate the stone off-site to avoid dust in the house, and install the backsplash with a waterproof membrane behind it so Inland Empire heat and dry air don’t crack the grout lines.

What Kitchen Remodeling Costs in Rancho Cucamonga

Item Typical range in Rancho Cucamonga
Cabinet replacement and layout changes $18,000 – $40,000
Countertop and backsplash upgrades $6,000 – $15,000
Full kitchen remodel (combined scope) $35,000 – $80,000

Will the price change once the work starts?

No – not unless you change the scope. We write fixed-price, line-item quotes in Rancho Cucamonga, and any change order is priced and approved in writing before a crew touches it. That protects you from open-ended contracts that drift upward mid-project. Call (866) 730-4828 for an exact quote on your kitchen.

How long does a kitchen remodel take in Rancho Cucamonga?

A typical Rancho Cucamonga kitchen remodel runs 4 to 8 weeks depending on cabinet lead times, slab work, and whether the city requires HOA review before permit approval. We give you a week-by-week schedule before we start, and we stick to it. Call (866) 730-4828 to get a timeline for your specific project.

Brands We Service in Rancho Cucamonga

We source from the ADU brands you’ve already researched – Abodu, Cover, Dvele, and others – so the comparison happens up front, not after you’re locked into one system. For exterior cladding, we specify our brands with James Hardie fiber-cement products where durability and fire resistance matter, especially on foothill lots. That means your ADU exterior stands up to Rancho Cucamonga’s heat and Santa Ana winds rather than baking under them.

Pricing for ADU Company in Rancho Cucamonga, CA

Service Typical range in Rancho Cucamonga
Kitchen remodel – cabinets and layout $18,000 – $40,000

Prices in Rancho Cucamonga push higher when the lot is on a slab that needs concrete cutting for plumbing moves, when an HOA design review adds a round of revision before the city permit can be submitted, or when foothill fire-zone requirements add material costs to the exterior. We quote fixed, line-item pricing up front, and we don’t file change orders without your written sign-off. Call (866) 730-4828 for a free estimate on your specific project.

What Rancho Cucamonga Customers Say

★★★★★ 4.8 from 4+ reviews

"The kitchenette layout he suggested made better use of the space than the one on our original sketch."

— Kelly Schaefer

"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."

— Wade Pruitt

"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."

— Emily Yang
