ADU Company in Fontana, CA
Kitchen remodeling in Fontana means working with what the 1950s and 1960s gave us: compact galley layouts, original single-pane aluminum windows, and electrical panels that were never sized for a modern appliance lineup. Add in Inland Empire summers that push past 100°F and you get kitchens that need real thought around ventilation, cooling, and heat-generating appliances, not just new cabinet faces. Uptown ADU Builders has served Fontana since 2018, and we approach every kitchen here as a rework of the home’s original bones, not a surface refresh. Call (877) 752-4191 to talk through your kitchen, your lot, and what a realistic budget looks like.
Why Fontana Homes Are Different
Fontana’s housing stock was built fast, mostly between the early 1950s and late 1970s, to house steel-mill and rail workers. That means single-story stucco-over-wood-frame tract homes on modest lots, with shallow-pitch or flat composite roofs and detached or attached garages at the rear. Many of those garages open onto named alleys, a pattern you see consistently on the older south-side streets. For ADU work, that alley access changes everything: a detached unit can often face the alley with its own address, its own parking, and a utility-trenching plan that follows the rear property line instead of cutting across the front yard.
The climate is the other constant. Fontana sits in the hot, dry Inland Empire, where summer highs routinely exceed 100°F and Santa Ana winds blow through in the fall. Any structure we build or remodel here needs cooling and shading designed as a system: deep overhangs on west-facing windows, high-efficiency heat pumps, and attic or roof insulation well beyond code minimum. A detached ADU with a west-sun exposure will bake without deliberate orientation and ventilation choices. We plan for that from the first site walk, because retrofitting shade onto a hot box after the fact is expensive and never as effective.
One more thing we see on nearly every Fontana ADU project: aging electrical panels, often 100-amp, and original plumbing that predates current code. These are not optional upgrades once you add a second unit with its own kitchen and bath. The garage slabs and older backyard sheds that look like easy conversion candidates frequently need structural review before anything gets permitted. Knowing that up front keeps the budget honest.
Our Main Fontana Services
The two services Fontana homeowners call us about most are ADU construction and bathroom remodeling, both of which tie directly into how this city’s homes were originally built and how families use them today.
ADU Builders in Fontana
Most Fontana ADU conversations start with a detached garage sitting empty at the back of the lot or a rear-yard footprint that has never been used for anything but storage. The alley-access pattern on many south-side streets means a detached ADU can often be built with its own address and parking, which changes the feasibility math in your favor. We walk every lot before recommending a strategy: garage conversion, rear-yard detached build, or a Tuff Shed-based pathway when the budget and lot call for it. One build, one permit path, one accountable team. ADU Builders in Fontana

Bathroom Remodeling in Fontana
Original Fontana bathrooms are small, often 5-by-8 or smaller, with cast-iron tubs, single-sink vanities, and ventilation that was never up to the job. The dry heat hides moisture problems until they are already inside the walls. We remodel these bathrooms with the same discipline we bring to ADU builds: moisture-resistant materials, correct exhaust ventilation, and layouts that make a compact footprint actually work. If the bathroom is part of an ADU project, it is handled by the same team, not subbed out. Bathroom Remodeling in Fontana

Kitchen Remodeling in Fontana
Kitchen remodeling in Fontana is about fixing the mismatch between a 1950s or 1960s floor plan and how a family actually cooks and lives now. Those original kitchens were built for a different era: fewer appliances, smaller refrigerators, no microwave, no dishwasher in most cases, and certainly no air fryer living permanently on the counter. Add in slab-on-grade foundations that make plumbing moves more involved than a simple re-route, and you need a contractor who plans the mechanical work before the cabinet order ever goes in. We handle the full kitchen remodel, from layout and plumbing to cabinetry, countertops, and finish work, so there’s no handoff between structure and interior finish. Kitchen Remodeling gives you more detail on our process.
The heat is a real factor here too. A Fontana kitchen with original single-pane windows and no real exhaust gets uncomfortable fast in July, and a range hood that dumps hot air straight back into an attic is a mold risk waiting to happen. We size ventilation and consider cooling load as part of the remodel, not as an afterthought. Range placement, window orientation, and the location of the existing 100-amp panel all shape the plan. Many Fontana kitchens also sit on original slab foundations, so relocating a sink or adding an island with plumbing means cutting concrete, which we factor into cost and timeline from the first estimate.
Full Kitchen Renovation
Signs you need it
Your kitchen still has the original 1950s-70s layout, single-pane aluminum windows, and a 100-amp panel that cannot support a modern cooktop plus refrigerator plus dishwasher all running at once.
What it costs in Fontana
A full kitchen renovation in Fontana typically runs $55,000 to $110,000 depending on square footage, plumbing moves, and finish level.
How we do it
We begin with a site measurement and panel assessment, then plan the layout around existing slab plumbing where possible, order cabinets and counters, run new electrical and ventilation, and finish with flooring, backsplash, and trim.
Cabinet Refacing and Countertop Replacement
Signs you need it
The cabinet boxes are sound but the doors, drawer fronts, and counters are dated, worn, and no longer match how you actually use the kitchen.
What it costs in Fontana
Cabinet refacing and countertop replacement in Fontana usually lands between $18,000 and $35,000 depending on door style, counter material, and linear footage.
How we do it
We assess the existing boxes for square and stability, replace doors and drawer fronts, install new counters with proper overhang and sink fitment, and re-hang hardware to spec.
What Kitchen Remodeling Costs in Fontana
| Item | Typical range in Fontana |
|---|---|
| Full kitchen renovation | $55,000 – $110,000 |
| Cabinet refacing and countertop replacement | $18,000 – $35,000 |
| Kitchen island addition with plumbing | $12,000 – $28,000 |
Prices move up when the slab has to be cut for plumbing relocation, when the panel needs an upgrade to 200 amps, or when the existing kitchen falls short of current California energy and ventilation code. Our written estimates line-item every cost before work starts, and the price does not change mid-project without your written sign-off.
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, with slab plumbing work and panel upgrades adding one to two weeks. Cabinet and counter replacements typically run 2 to 4 weeks.
Will my Fontana kitchen remodel need a panel upgrade?
If your home still has a 100-amp panel, adding a modern cooktop, dishwasher, and ventilation often triggers an upgrade to 200 amps. We assess this during the estimate, not after demo starts. Call (877) 752-4191 for an exact quote.
