ADU Company in Rancho Cucamonga, CA

Kitchen remodeling in Rancho Cucamonga runs $25,000 to $65,000 for a full gut renovation in a 1960s-80s ranch or Spanish-style home, and most projects take 6 to 10 weeks from demo to final walkthrough. We’re Cottage ADU Builders, and we’ve been remodeling kitchens and building ADUs in this city since 2012. The homes here, especially in Alta Loma and the foothill ZIPs of 91701, 91737, and 91739, bring dated electrical panels, older slab conditions, and floor plans that weren’t designed for how families cook and gather today.

Why Rancho Cucamonga Homes Are Different

Rancho Cucamonga is not a one-house-type city. The west side, through Alta Loma, Deer Creek, and Hermosa, holds a large share of half-acre-plus horse-zoned lots with ranch homes built from the 1960s through the 1980s. Those houses have detached garages, deep rear yards, and generous setbacks, and their kitchens often sit in the original footprint with original electrical service. The east side and the 91730 ZIP hold newer 1990s-2000s tract subdivisions with tighter lots and more standard floor plans, but those homes are now hitting the age where builder-grade cabinets and appliances are failing together.

Climate shapes the work too. Rancho Cucamonga summers routinely push past 100°F, and Santa Ana winds hit foothill lots hard. That means ventilation, range hood ducting, and HVAC tie-ins have to be planned for real heat loads, not just code minimums. Homes at the base of the Cucamonga foothills also deal with wind-driven dust and stronger sun exposure, so window placement and exterior wall details matter in a kitchen remodel here more than they would in a coastal city. When we price a Rancho Cucamonga kitchen, we’re looking at the panel, the slab, the duct run, and the wind exposure, not just cabinet boxes.

Our Main Rancho Cucamonga Services

Most homeowners in Rancho Cucamonga call us about one of two things: adding a detached ADU at the back of a deep lot, or remodeling a bathroom in an older ranch home. Both jobs share a common thread here, which is working with 40-to-60-year-old structures and the grading, setback, and utility realities that come with them.

ADU Builders in Rancho Cucamonga

On the horse-zoned and foothill lots of Alta Loma and Deer Creek, an ADU is usually a detached second unit or a garage conversion set well back from the street. That changes everything: utility trenching distances, fire-defensible space requirements, hillside grading rules, and sewer or septic lateral runs. We’ve been building ADUs in Rancho Cucamonga since 2012, and we’re fluent in prefab systems like Abodu, Plant Prefab, and Tuff Shed, so you get an honest read on which delivery method fits your lot and budget rather than a one-system pitch.

Bathroom Remodeling in Rancho Cucamonga

Rancho Cucamonga ranch homes often have small, compartmentalized bathrooms with original cast-iron drain lines and dated electrical. A bathroom remodel here frequently involves moving a wall, updating the shower pan to a curbless or low-threshold design, and bringing the vent fan up to code for a house that may never have had proper moisture management. We handle the full scope, from demo to tile to fixtures, and we know which permit questions the city will ask before we open the first wall. Bathroom Remodeling in Rancho Cucamonga

Kitchen Remodeling in Rancho Cucamonga

Kitchen remodeling in Rancho Cucamonga means something specific: taking a 1960s-80s ranch or Spanish-style kitchen with its original footprint, original panel, and original slab, and turning it into a room that works for how the household actually lives. The heat matters too. A kitchen in this city needs a real ventilation plan, proper cooling load consideration, and insulation details that a milder-climate remodel can skip.

We’re a Kitchen Remodeling contractor who also builds ADUs, which means we understand how a kitchen in the main house and a kitchenette in a back-lot unit need to share or split utility capacity. That coordination is the part most generalist remodelers miss in Rancho Cucamonga.

Outdated Layout Changes

Signs you need it

The kitchen is walled off from the dining room, the peninsula cuts the room in half, or the cook can’t work without blocking the sink or the fridge.

What it costs in Rancho Cucamonga

Opening walls and reconfiguring the footprint typically runs $35,000 to $65,000 depending on whether you’re moving plumbing, adding a beam, or reworking the electrical.

How we do it

We start with load-bearing and panel assessments, then demo the non-structural walls, reframe the new opening, reroute plumbing and electrical, and finish with flooring, cabinetry, and countertops.

Cabinet and Counter Replacement

Signs you need it

The cabinet boxes are swollen, the drawer slides fail, or the laminate counters are peeling at the edges and you want a full replacement without moving walls.

What it costs in Rancho Cucamonga

A full cabinet and counter replacement in Rancho Cucamonga usually lands between $25,000 and $45,000, with cost driven by cabinet line and countertop material.

How we do it

We remove the old cabinets and counters, inspect the wall framing and plumbing stub-outs, install the new boxes and doors, template and set the new counters, and finish with backsplash and appliance reconnection.

What Kitchen Remodeling Costs in Rancho Cucamonga

Item Typical range in Rancho Cucamonga
Layout change / wall removal $35,000 – $65,000
Cabinet and counter replacement $25,000 – $45,000
Minor kitchen refresh $10,000 – $25,000

How long does a kitchen remodel take in Rancho Cucamonga?

A full kitchen remodel typically takes 6 to 10 weeks from demo to final walkthrough. Cabinet lead times and any hidden framing or slab work are the two biggest schedule variables. Call (866) 808-7312 for a timeline specific to your project.

Will my Rancho Cucamonga kitchen need a panel upgrade?

Homes built in the 1960s through the 1980s in Rancho Cucamonga often have 100-amp panels, and a modern kitchen with induction, double ovens, and dedicated appliance circuits can exceed that. We assess the panel during the estimate, not after the walls are open. Call (866) 808-7312 to schedule a free estimate.

What Rancho Cucamonga Customers Say

★★★★★ 4.8 from 4+ reviews

"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."

— Shane Miller

"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."

— Amanda Walsh

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

— Lucia Flores
