ADU Company in Fontana, CA
Kitchen remodeling in Fontana usually means working inside a 1950s to 1980s stucco tract home, where the original galley kitchen still has its first set of cabinets and a layout that never anticipated how families cook today. We handle that work from first measurements to final walkthrough, and we also build ADUs and remodel bathrooms across Fontana’s 92334, 92335, 92336, and 92337 ZIP codes. Call (866) 808-7312 to talk through your project.
Why Fontana Homes Are Different
Fontana’s housing stock is heavy on single-story stucco tract homes built between the 1950s and 1980s, most sitting on slab foundations with deep lots that run wider than what you’ll find closer to Los Angeles. That lot depth matters for ADU work, but it also shapes kitchen and bath remodels, because many of these homes still carry their original floor plans. A galley kitchen in a 1960s Fontana tract home is often closed off from the living space, which means the remodel is as much about removing a wall as it is about new cabinets.
The climate here is genuinely punishing on interiors in ways coastal contractors don’t always plan for. Summer heat in the Inland Empire pushes attic temperatures high enough that cabinet finishes and laminate surfaces degrade faster, and Santa Ana winds drive fine dust into every gap. That affects material selection: we steer Fontana clients toward cabinet boxes and door finishes that hold up under heat and low humidity, and we pay close attention to range hood ventilation, because a poorly vented kitchen in Fontana fights the cooling system all summer.
Permit realities vary by tract and block. Fontana’s planning department applies its own development standards on top of California’s state ADU preemptions, and what worked for a neighbor two streets over may not match your lot’s setback or access path. We confirm that up front, before design work starts, so you’re not paying for drawings that won’t clear plan check. That dual-layer reality, state rules meeting Fontana’s local zoning approach, is the single biggest reason to work with a contractor who has done this in Fontana specifically rather than one who treats every Inland Empire city as the same job.
Our Main Fontana Services
Most Fontana homeowners call us about one of two projects: adding a detached or garage-conversion ADU on their oversized lot, or bringing a dated bathroom up to modern standards. Here’s how each works here.
ADU Builders in Fontana
Fontana’s deep lots and detached rear garages make this city one of the strongest ADU markets in the Inland Empire. In the older 92335 tract blocks especially, a rear garage set against the property line is often a faster, cleaner conversion than starting from bare dirt, but the actual setback and utility routing have to be verified lot by lot. We work with prefab and modular systems including Abodu, Plant Prefab, and Tuff Shed so you’re choosing the right delivery method and foundation approach for your specific site.

Bathroom Remodeling in Fontana
Fontana’s 1960s and 1970s tract bathrooms were built with compact footprints and original cast-iron plumbing that is now reaching the end of its service life. A typical remodel here involves replacing the tub or shower surround, updating the vanity and floor, and often reworking the layout enough to gain a few usable inches. Because these homes sit on slab foundations, moving a drain line means cutting concrete, which changes the scope and price compared to a raised-foundation home near the coast. Bathroom Remodeling in Fontana has the full breakdown.

Kitchen Remodeling in Fontana
A kitchen remodel in Fontana rarely stops at new cabinet faces. Most of the homes we work in were built between the 1950s and 1980s, so the original kitchen is a closed-off galley with one work triangle, minimal counter space, and cabinetry that has been through four decades of Inland Empire heat. The work usually involves opening the space, replacing all surfaces, upgrading the ventilation, and correcting decades of deferred maintenance under the sink and behind the appliances. For a broader look at how we approach this service, see our Kitchen Remodeling overview.
Full Galley Kitchen Remodel
Signs you need it
Your Fontana kitchen is still a closed-off galley with original cabinets, one narrow walkway, and no room for two people to cook at once.
What it costs in Fontana
A full galley kitchen remodel in Fontana typically runs $35,000 to $75,000 depending on layout changes and finish level.
How we do it
We confirm the load-bearing points, remove the dividing wall where feasible, reroute plumbing and electrical to the new layout, then install cabinets, counters, flooring, and appliances in sequence.
Cabinet Replacement and Refacing
Signs you need it
The cabinet boxes are sound but the doors are delaminating, the hinges are failing, or the finish has gone chalky from Fontana’s dry heat.
What it costs in Fontana
Cabinet replacement in Fontana generally falls between $12,000 and $28,000 depending on linear footage and door style.
How we do it
We measure every run, order the new doors and boxes to fit the existing footprint, remove the old units, and install the new cabinetry with soft-close hardware and adjusted reveals.
Countertop and Backsplash Upgrade
Signs you need it
Your countertops are original laminate with burned edges near the range, and the backsplash is cracked or dated tile that no longer seals against moisture.
What it costs in Fontana
Countertop and backsplash replacement in Fontana typically costs $4,000 to $12,000 depending on material and square footage.
How we do it
We template the existing runs, remove the old surfaces without damaging the cabinet boxes, and install the new counter and backsplash with proper sealing at every joint.

How long does a kitchen remodel take in Fontana?
Most full kitchen remodels in Fontana take 6 to 10 weeks from demo to final walkthrough. Cabinet-only jobs run 2 to 4 weeks, and countertop upgrades often finish in under 2 weeks. Permit review time varies and is confirmed before we start. Call (866) 808-7312 for a schedule based on your scope.
Will my Fontana kitchen remodel require a permit?
Yes, if you’re moving plumbing, electrical, or any wall. Fontana’s building department requires permits for those changes, and we pull them as part of the job. Cosmetic-only work like cabinet refacing typically does not need one. Call (866) 808-7312 and we’ll tell you exactly what your scope triggers.
Brands We Service in Fontana
We work with the prefab and modular systems Fontana homeowners are already researching, including Abodu, Plant Prefab, and Tuff Shed, and we use James Hardie fiber-cement siding on applicable exterior applications. That means you get straight guidance on which system fits your lot, budget, and timeline rather than a pitch for one product. See our brands for the full list.

What Fontana Customers Say
"The kitchenette layout he suggested made better use of the space than the one on our original sketch."
— Lucia Flores"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Ernesto Hernandez"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
