ADU Company in Fontana, CA
Kitchen remodeling in Fontana usually runs between $35,000 and $85,000 for a full renovation, with smaller refreshes landing closer to $15,000 to $25,000. The city’s housing stock spans 1950s stucco tract homes in the southern core and larger 1980s-2000s tile-roof subdivisions up north, which means we’re often working with aging slab foundations, outdated electrical panels, and floor plans that need rethinking rather than just resurfacing. Home Base ADU Builders has served Fontana since 2016, and we’ve learned that every job here starts with the house telling us what it can and can’t do. Call (866) 403-9834 to talk through your kitchen.
Why Fontana Homes Are Different
Fontana sits in the hot, dry Inland Empire, where summer highs routinely run past 100°F and Santa Ana wind events roll through from the canyons. That climate shapes the work. Kitchens in Fontana need ventilation that actually moves hot air out, flooring that doesn’t buckle when the house cools down at night, and cabinetry built to handle dry heat without warping. We spec materials accordingly: tile and engineered stone over soft woods, range hoods with real CFM, and paint and finishes rated for UV exposure.
The older southern core, mostly 1950s-60s stucco tract homes, brings a different set of challenges. These lots are generous and often have room to expand, but the plumbing is cast iron, the slabs have settled, and the electrical service usually topped out decades ago. In the northern ZIPs like 92336 and 92337, the houses are newer but often sit inside HOAs with architectural review requirements for anything visible from the street. We pull permits for every job, coordinate with HOA boards when needed, and make sure the work passes inspection the first time.
Our Main Fontana Services
Most Fontana homeowners call us for one of two things: an ADU in the backyard or a bathroom that’s finally getting the attention it deserves. Both play into how families actually live in this city, and both come with their own set of local realities.
ADU Builders in Fontana
Fontana’s ADU market is driven by large lots, multi-generational families, and a long local tradition of garage conversions. Homeowners in ZIPs 92335, 92336, and 92337 build detached casitas for parents, adult children, or extended relatives, more often than for rental income. That means the ADU has to fit around existing pools, block walls, and RV parking pads, and it has to feel like part of the family compound, not an afterthought. We walk every lot before recommending a build path, whether that’s a Tuff Shed conversion for a tight budget or a Plant Prefab unit for something more finished. ADU Builders in Fontana is the page to start with.

Bathroom Remodeling in Fontana
Bathrooms in Fontana’s older homes are small, often original to the 1950s or 60s, and usually not keeping up with how families live now. We rebuild them around walk-in showers, dual vanities, and proper ventilation so the drywall stops collecting moisture during those hot shower-and-dry-air cycles. Working with one contractor for the bathroom and the ADU means the plumbing and electrical work gets coordinated instead of patched together by separate crews. See Bathroom Remodeling in Fontana for what’s involved.

Kitchen Remodeling in Fontana
Kitchen remodeling in Fontana is about fixing what the original builders got wrong: galley kitchens with no flow, thin slab counters that stain, and electrical panels that can’t handle a modern appliance lineup. The city’s older southern homes, especially in 92335, were built when one cook and a four-burner range was the norm. Now there are multi-generational households where three people might be in the kitchen at once. We open up floor plans where the slab and roofline allow, move plumbing for new island sinks, and upgrade panels so a double oven and a range hood can run at the same time without tripping a breaker. In the northern subdivisions, we’re more likely to be swapping out builder-grade everything for materials that hold up to high-heat summers and busy family use. The full scope of what we do lives on our Kitchen Remodeling page, but here’s how it usually goes in Fontana.
Full Kitchen Renovation
Signs you need it
If your Fontana kitchen still has its original 1950s-60s layout with a wall oven blocking traffic and cabinets falling apart at the hinges, it’s time.
What it costs in Fontana
A full kitchen renovation in Fontana typically runs $35,000 to $85,000 depending on cabinet grade, appliance package, and whether we move plumbing or walls.
How we do it
We demo to the studs, upgrade plumbing and electrical, rebuild the layout around how your family cooks, and finish with cabinets, counters, and appliances specified for local heat and humidity conditions.
Kitchen Refresh
Signs you need it
Your cabinets are solid but the doors are dated, the countertops show every stain, and the cooktop struggles to boil water for pasta night.
What it costs in Fontana
A kitchen refresh in Fontana, focused on cabinet refacing, new counters, and a better hood, usually lands between $15,000 and $25,000.
How we do it
We reface or replace cabinet doors, install new counter surfaces, swap the faucet and fixtures, and add ventilation that actually keeps the kitchen comfortable in July.
What Kitchen Remodeling Costs in Fontana
| Item | Typical range in Fontana |
|---|---|
| Cabinet refacing | $7,000 – $15,000 |
| Countertop replacement | $4,000 – $12,000 |
| Full kitchen renovation | $35,000 – $85,000 |
Prices move most on two things: whether we’re moving plumbing, and what the electrical panel can handle without an upgrade. Older Fontana homes with 100-amp service often need a panel swap before the new appliances go in, and that’s a real line item we’ll show you up front.
Do you pull the permits?
Yes. We pull all required city and county permits for kitchen remodels in Fontana, including electrical and plumbing, and we schedule the inspections. Call (866) 403-9834 for specifics on your project.
Will the price change once work starts?
Our quotes are fixed-price with no change orders unless you change the scope. If we open the wall and find something the original contractors buried, we’ll show it to you and re-quote before proceeding. Call (866) 403-9834 to get a written estimate.

What Fontana Customers Say
"Knew the local setback and parking rules cold, which saved us from designing something that would never have been approved."
— Priya Mehta"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."
— Luis Garcia"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."
— Robert Hayes
