ADU Company in Fontana, CA

Kitchen remodeling in Fontana usually means reworking a 1950s stucco tract home or a 1990s subdivision house to handle how families actually live now, while adding enough insulation and cooling capacity for summers that sit above 100°F. Fullerton ADU Builders has served Fontana since 2017, and we keep our scope tight: ADU construction, kitchen remodeling, and bathroom remodeling. If you are weighing a kitchen remodel against an ADU rental unit or multigenerational suite, call (877) 801-4497 and we will help you sort the numbers first.

Why Fontana Homes Are Different

Fontana’s housing stock was built in two distinct waves, and each one shapes kitchen and ADU work differently. The older southern neighborhoods and pockets of 92335 hold 1950s and 1960s single-story stucco homes on 6,000 to 7,000 square foot lots. Those houses often still run on shallow slabs and single-panel electrical services, which means a kitchen remodel that adds an induction cooktop, double oven, or dedicated appliance circuits usually requires a panel upgrade before the first cabinet comes out. The newer 92336 subdivisions from the 1980s through the 2000s are two-story and framed differently, but they were built for a cooler climate than the one Fontana actually has now.

Summer heat is the single biggest design consideration here. Temperatures routinely pass 100°F for stretches of July and August, and Santa Ana winds push dry air through the city every fall. That combination punishes cheap insulation, undersized range hoods, and west-facing windows without proper glazing. We specify insulation and HVAC sizing for Fontana’s actual peak loads, not a generic Southern California baseline. Homes in 92334, 92335, 92336, and 92337 all deal with the same heat, though older slabs and tighter lot lines near the southern edge of town add their own constraints.

Our Main Fontana Services

Fontana homeowners call us most often about two projects: building an ADU on an existing lot and remodeling a bathroom in an aging home. Here is how each one works here.

ADU Builders in Fontana

Detached garage conversions dominate Fontana’s ADU pipeline because so many 1950s and 1960s lots have a garage sitting on the rear property line with a cinderblock wall that slopes into the neighbor’s yard. That shared-wall condition often triggers a lot-line adjustment or a parapet-to-shared-wall redesign before the city signs off. We are brand-agnostic on ADU delivery: the lot, setbacks, and budget dictate whether a prefab unit or a site-built conversion makes sense. ADU Builders in Fontana covers the full breakdown.

Bathroom Remodeling in Fontana

Bathroom remodels in Fontana’s older tract homes usually mean working inside a 5-by-8 footprint with cast iron drain lines that have been in the ground for sixty years. We routinely replace failing tub surrounds, re-set toilets on new flanges, and add exhaust fans sized for a bathroom that has never had proper ventilation. The goal is a bathroom that survives Fontana’s hard water and summer humidity without needing attention again in five years. Bathroom Remodeling in Fontana has the full scope and pricing detail.

Kitchen Remodeling in Fontana

Kitchen remodeling in Fontana is mostly about fixing two things at once: layouts that were designed for a 1960s family’s cooking habits and climate performance that was never adequate for the Inland Empire heat. Homes in 92335 and 92337 often have galley kitchens with a single oven, no hood, and cabinets that have baked in dry heat for decades. We open those walls, upgrade the electrical and ventilation, and rebuild the kitchen to handle daily cooking plus the occasional big family gathering. If you are planning a kitchen remodel alongside an ADU, our Kitchen Remodeling team handles both scopes so you are not coordinating two contractors.

Full Gut Kitchen Remodel

Signs you need it

Your kitchen has original 1960s cabinets, the floor plan traps two people in a narrow galley, and the electrical panel cannot support a modern range or refrigerator without tripping breakers.

What it costs in Fontana

A full gut kitchen remodel in Fontana typically runs $45,000 to $75,000 depending on layout changes, cabinet grade, and how much electrical and plumbing work the old house needs.

How we do it

We demo to the studs, replace or upgrade the subfloor, rerun electrical and plumbing to current code, install new insulation and drywall, then set cabinets, counters, appliances, and finishes in sequence.

Cabinet Refacing and Countertop Replacement

Signs you need it

Your cabinet boxes are structurally sound but the doors are dated, the hinges are failing, and the laminate counters are chipped or burned.

What it costs in Fontana

Refacing cabinets and replacing counters in a Fontana kitchen typically costs $15,000 to $30,000, depending on door style, veneer quality, and the counter material you choose.

How we do it

We remove existing doors and drawer fronts, prep and veneer the cabinet boxes, install new doors and hardware, then template and set the new countertops in one pass.

Kitchen Island Addition and Layout Reconfiguration

Signs you need it

You have dead floor space in the middle of the kitchen, no landing zone next to the range, and the current layout forces traffic through the cooking area to reach the back door.

What it costs in Fontana

Adding an island and reconfiguring a Fontana kitchen layout typically costs $20,000 to $40,000, since it usually involves moving plumbing, gas, or electrical lines.

How we do it

We map the new traffic flow, relocate the rough-in utilities, frame the island, run power and plumbing to it, then finish the surrounding flooring and cabinetry so the change looks original.

What Kitchen Remodeling Costs in Fontana

Item Typical range in Fontana
Full gut kitchen remodel $45,000 – $75,000
Cabinet refacing and counter replacement $15,000 – $30,000
Kitchen island addition and layout reconfiguration $20,000 – $40,000

These ranges reflect Fontana’s older housing stock, where electrical panel upgrades and slab plumbing tweaks are common enough that we build them into the estimate up front. You will get a written line-item quote before work starts, and the price does not change unless you change the scope.

How long does a kitchen remodel take in Fontana?

Most Fontana kitchen remodels take five to nine weeks, depending on whether we are moving plumbing, upgrading the electrical service, or waiting on city inspections for structural changes. A straight cabinet and counter swap can finish in two to three weeks.

Do I need a permit for a kitchen remodel in Fontana?

Yes, any Fontana kitchen remodel that moves electrical, plumbing, or walls needs a city permit. We pull the permits, schedule the inspections, and do not close up any wall until the inspector has signed off. Call (877) 801-4497 for an exact quote on your kitchen.

Brands We Service in Fontana

We work with James Hardie fiber cement cladding, Abodu, Cover, and Dvele prefab ADU systems, and we stock common replacement parts locally so a cabinet or panel issue does not stall your project. Our our brands page lists the full roster and what each system handles best.

Pricing for ADU Company in Fontana, CA

Service Typical range in Fontana
Full gut kitchen remodel $45,000 – $75,000
Cabinet refacing and countertop replacement $15,000 – $30,000
Kitchen island addition and layout reconfiguration $20,000 – $40,000

Fontana pricing runs higher than coastal Orange County on some items because older 1950s and 1960s homes here often need electrical panel upgrades and slab plumbing work before the cosmetic work can start. Every quote is line-itemed in writing, and the price you approve is the price you pay unless you add scope mid-project.

Neighborhoods We Serve in Fontana

We work across Fontana’s full span, from the older single-story tract streets in the south through the 92335 and 92336 subdivisions up toward the newer 92337 developments. Our crews know which eras of construction are common in each area and what that means for slab access, wall framing, and electrical service.

  • Older southern tract neighborhoods near downtown
  • Subdivisions in 92335
  • Subdivisions in 92336

What Fontana Customers Say

★★★★★ 4.8 from 4+ reviews

"The kitchenette layout he suggested made better use of the space than the one on our original sketch."

— Marisol Guzman

"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."

— Greg Reed

"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."

— Erin Ziegler
