ADU Company in Fontana, CA
Kitchen remodeling in Fontana usually means working inside a 1950s-to-1980s stucco ranch home where the original footprint was built for a different era of cooking, and the real challenge isn’t just new cabinets. It’s electrical service that never anticipated today’s appliances, plumbing that’s been in the slab since Nixon was in office, and a layout that walls the kitchen off from the rest of the house. Casita ADU Builders has served Fontana since 2013, and our ADU-only focus means when we open up a Fontana kitchen, we’re already thinking about the same structural realities that shape every accessory dwelling unit we build across the 92335 and 92336 ZIP codes.

Why Fontana Homes Are Different
Fontana’s housing stock is dominated by single-story stucco tract homes built from the 1950s through the 1980s, and those decades show up in the walls the moment a remodel starts. We regularly find original electrical panels rated for 60 or 100 amps when the homeowner’s new kitchen plan calls for induction cooktops, double ovens, and a dedicated circuit for a microwave that wasn’t in the 1962 spec. The slab foundations are real too: much of Fontana’s older plumbing runs through concrete, which means moving a sink or adding an island with a prep sink isn’t a simple pipe extension, it’s a core cut and a re-route. The hot inland summers shape design decisions – heavy attic insulation, high-efficiency range hoods that don’t fight the AC, and finishes that won’t warp when the Santa Anas push dry, dusty air through every window seal. And because so many Fontana lots trace back to the citrus-era land division of the 1940s and 50s, the lots are genuinely generous: wide side yards, detached garages off the alley, and enough setback room that homeowners here get to make choices – add on, convert, or build a casita out back. That housing reality is why Fontana leans so heavily toward detached ADUs and garage conversions rather than the tight interior remodels that dominate older LA County cities to the west.
Our Main Fontana Services
Fontana homeowners call us most about two things: adding a detached or garage-conversion ADU to a mid-century lot, and remodeling the bathrooms inside those same aging ranch homes. Here’s what each looks like in Fontana.
ADU Builders in Fontana
Fontana’s post-WWII and 1960s-70s tract homes sit on lots with real room, which means the typical job here is a detached backyard unit or a converted garage off the alley – not a cramped interior carve-out. That changes the permitting conversation: we’re usually dealing with San Bernardino County setback requirements, mature citrus-era lot lines, and original garage slabs that sometimes need structural evaluation before a conversion can be signed off. We work across leading prefab and modular brands, and we also handle Tuff Shed conversions for homeowners who want a faster, lower-cost path to rentable square footage. ADU Builders in Fontana is where you’ll find the full scope of what’s possible on your specific lot.
Bathroom Remodeling in Fontana
Fontana bathrooms from the 1960s and 70s are small, tiled to the ceiling, and often still running on original galvanized supply lines that are corroding from the inside out. When we remodel a bathroom in the 92336 or 92337 ZIP codes, the work frequently includes a full repipe of the wet wall, new waterproofing behind the tile, and ventilation upgrades that matter in a climate where summer heat pushes moisture into attics fast. We do the full interior under one contract, which means your bathroom and your ADU kitchen don’t get handed off to a second crew. Bathroom Remodeling in Fontana covers the details.

Kitchen Remodeling in Fontana
Kitchen remodeling in Fontana is about more than countertops. The homes here – mostly 1950s through 1980s tract builds with slab foundations and original electrical – require a remodel approach that starts with the bones, not the backsplash. Before we touch a cabinet face, we’re checking whether the panel can carry the new load, whether the slab plumbing will cooperate with the island you want, and whether the existing ventilation can actually move air in a Fontana August. This is the same discipline we bring to our ADU builds: fix the infrastructure first, then make it beautiful. Our Kitchen Remodeling work is always done by one team under one contract, which matters when your remodel scope touches electrical, plumbing, and finishes that most general contractors would sub out three different ways.
Full Kitchen Remodel
Signs you need it
You’re working around a layout that walls the kitchen off from the dining area, the cabinet boxes are delaminating, and the appliances trip a breaker when the toaster and microwave run at the same time.
What it costs in Fontana
A full kitchen remodel in Fontana typically runs $45,000 to $90,000 depending on layout changes, cabinet grade, and how much slab plumbing or electrical rework the original footprint requires.
How we do it
We start with electrical and plumbing scope verification, demo to the studs, re-route slab plumbing if the layout moves, install new panel capacity as needed, then build back with new cabinetry, counters, plumbing fixtures, and finishes – all permitted and inspected through San Bernardino County or the City of Fontana.
Countertop and Cabinet Refresh
Signs you need it
The cabinet frames are solid but the doors are shot, and the laminate counters are peeling at the seams or showing water damage around the sink.
What it costs in Fontana
A countertop and cabinet refresh in Fontana typically runs $8,000 to $25,000 depending on square footage, quartz versus natural stone, and whether we’re replacing boxes or just doors and drawer fronts.
How we do it
We template for new stone, demo the old tops, reface or replace cabinet doors and hardware, reset the sink and cooktop, and rework the backsplash – usually a two-to-three-week job if the plumbing stays put.

What pushes a Fontana kitchen or ADU price up is the stuff hiding inside the original construction: an old 100-amp panel that can’t take the new load, slab plumbing that has to move, a garage slab with a crack running through the footprint, or dry rot in a 1960s exterior wall that only shows up after demo.

What Fontana Customers Say
"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."
— Aisha Prince"Knew the local setback and parking rules cold, which saved us from designing something that would never have been approved."
— Maria Martinez"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."
