ADU Company in Fontana, CA
Kitchen remodeling in Fontana usually means reworking a 1950s Kaiser Steel-era galley or a 1990s builder-grade L-shaped kitchen inside a stucco tract home that’s fighting 100-degree summers and dusty Cajon Pass winds. The houses are solid, but the original layouts, electrical panels, and ventilation weren’t built for how Fontana families cook now. Colonial ADU Builders handles the full kitchen remodel, from panel upgrades to cabinet installation, and we’re the same team Fontana homeowners call for ADU construction. Call (877) 265-9846 to talk through your kitchen or a backyard unit.
Why Fontana Homes Are Different
Fontana’s housing stock splits into two distinct eras, and each one changes how a remodel or ADU gets planned. The 92335 core is filled with single-story stucco tract homes from the Kaiser Steel buildout of the 1950s through the 1970s. These lots are generous, often quarter-acre or larger, and many have alley-loaded detached garages. The catch: original 100-amp electrical panels, galvanized supply lines, and shallow slab footings that haven’t been touched in sixty years. A kitchen remodel or ADU tie-in in these neighborhoods often starts with a panel and service upgrade before a single cabinet gets ordered.
Newer Fontana, concentrated in 92336 and 92337, is a different animal. Those 1990s and 2000s two-story stucco subdivisions have deep rear yards but narrow side yards, which tightens detached ADU placement against the 4-foot side and rear setback rules. Summer highs routinely exceed 100°F, and Fontana sits directly under the Cajon Pass wind corridor. That means insulation packages, mini-split sizing, and high-wind uplift hardware matter here in ways they never do in coastal cities. We design for heat and wind first, then square footage.
Our Main Fontana Services
Most Fontana homeowners come to us for one of two big projects: building an ADU on a lot that’s finally legal to develop under California’s relaxed ADU rules, or remodeling a bathroom that’s outlived its original 1960s tile and plumbing. Here’s what each looks like in Fontana specifically.
ADU Builders in Fontana
Fontana’s quarter-acre lots in 92335 and 92336 make detached ADUs mathematically feasible in a way that most of LA County can’t match. The older blocks with alley-loaded garages are particularly good candidates for garage conversions, though we always check the original slab and shared block walls before committing to a conversion versus a new detached unit. We work across seven prefab manufacturers plus fully site-built construction, so the recommendation is driven by your lot, budget, and timeline, not by what we happen to stock. ADU Builders in Fontana covers permit strategy, manufacturer selection, and local plan check realities in detail.
Bathroom Remodeling in Fontana
Fontana’s older homes carry a lot of original 1960s and 1970s bathrooms: cast-iron tubs, mud-set tile, and plumbing that predates modern fixture flow rates. Remodeling these rooms usually means opening walls anyway to replace galvanized supply lines, which is exactly the kind of work our in-house crews do without handing you off to subcontractors. Newer 92336 and 92337 homes tend toward oversized corner tubs and dated cultured-marble surrounds that come out cleanly. Bathroom Remodeling in Fontana explains what to expect from a full gut remodel in this city’s housing stock.

Kitchen Remodeling in Fontana
Kitchen remodeling in Fontana typically starts with electrical reality: many older 92335 homes still run 100-amp panels that can’t support a modern induction range, double ovens, and dedicated refrigerator circuits at once. We plan the panel and wiring work before we order cabinets, so the kitchen you get actually functions under load. Our in-house remodeling crews handle the whole job, and the same team builds ADU kitchens when you add a unit. For a deeper look at our approach, see Kitchen Remodeling.
Full Kitchen Gut
Signs you need it
Your 1950s-1970s Fontana kitchen has original cabinetry, a panel that trips when the microwave and toaster run together, and layout dead ends that trap traffic against the stove.
What it costs in Fontana
A full kitchen gut in Fontana runs from $45,000 to $85,000 depending on panel scope, cabinet grade, and how much plumbing relocation is needed in a slab foundation.
How we do it
We pull permits, upgrade the electrical panel if required, strip to studs, relocate plumbing and gas lines as needed, then install new cabinets, counters, appliances, flooring, and finish work with our own crews.
Cabinet Refacing and Countertop Replacement
Signs you need it
Your cabinet boxes are structurally sound but the faces are delaminating, hinges are failing, and the laminate counters are burned or swollen at the seams.
What it costs in Fontana
Refacing with new doors, drawer fronts, and veneer in Fontana runs $8,000 to $15,000, while a countertop-only replacement with mid-grade quartz runs $4,500 to $9,000 depending on square footage.
How we do it
We measure, order new faces and hardware, prep and bond veneers, then template and install new counters with a single crew so the seams and reveals line up correctly.
Kitchen Island and Layout Expansion
Signs you need it
Your kitchen has the square footage but the original layout walls it off, leaving one narrow galley path and no room for more than one cook.
What it costs in Fontana
Removing a structural wall and adding an island in Fontana runs $18,000 to $35,000 when it includes engineered beam work, flooring patch-in, and new lighting.
How we do it
We identify bearing walls, engineer the beam, pull permits, open the space, run new circuits for the island, then patch flooring and ceilings so the addition reads as original.
What Kitchen Remodeling Costs in Fontana
| Item | Typical range in Fontana |
|---|---|
| Full kitchen gut remodel | $45,000 – $85,000 |
| Cabinet refacing | $8,000 – $15,000 |
| Countertop replacement only | $4,500 – $9,000 |
Fontana’s cost pressure comes from two directions: the panel and service upgrades older homes need before any electrical load is added, and the sheer prevalence of slab-on-grade foundations that make moving a sink or range a concrete-cutting job. We price the full scope up front so the number doesn’t change once walls open.
How much does a kitchen remodel cost in Fontana?
Expect $45,000 to $85,000 for a full Fontana kitchen remodel, with cabinet refacing at $8,000 to $15,000 and counters at $4,500 to $9,000. Your final number depends on panel upgrades and whether plumbing moves. Call (877) 265-9846 for a written quote.

No. We write fixed-price quotes after we inspect the panel, slab, and existing plumbing. The only add-ons happen if you choose to expand scope after the contract is signed. Call (877) 265-9846 for an exact number.

What Fontana Customers Say
"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Todd Rhodes"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."
— Elena Torres"Every invoice was tied to a completed milestone, so I always knew what I was paying for."
— Beatriz Mendoza
