ADU Company in Fontana, CA

Kitchen remodeling in Fontana means working with 1950s – 1970s tract homes where original layouts feel tight, cabinets have seen decades of Inland Empire heat, and families want more function without adding square footage they don’t have. Orchard ADU Builders handles these remodels alongside ADU construction, so homeowners can upgrade the main house and add a rental or in-law unit under one contract. Call (844) 386-2399 to talk through your Fontana project.

Why Fontana Homes Are Different

Fontana’s core neighborhoods, especially in 92335 and parts of 92336, are dominated by single-story stucco tract homes and ranch-style houses built between the 1950s and 1970s. Many came with detached or attached two-car garages and alley access. That housing stock shapes what’s possible. The newer subdivisions north of the 210 in 92336 and 92337 sit on zero-lot-line parcels with narrow side yards, which pushes any ADU into a rear-yard footprint or a garage conversion rather than a side addition.

The climate is the other constant. Summer highs routinely pass 100°F, and Santa Ana winds push dust and grit across south Fontana’s open lots and freeway corridors. Any ADU or remodel here needs serious insulation, correctly sized mini-split HVAC, and exterior details that hold up to wind-blown debris. We account for all of that before we quote, because a code-minimum build that works in Orange County will bake and underperform in a Fontana July.

Our Main Fontana Services

Homeowners in Fontana call us most often about two things: building an ADU on an existing lot, or remodeling a bathroom in a house that hasn’t been updated in decades. Both require working with older stucco construction and the city’s permit process.

ADU Builders in Fontana

Fontana is a working-class Inland Empire city where ADU demand comes from multi-generational families and renters priced out of LA. The signature local constraint is that much of Fontana’s post-war housing sits on lots already built out with detached garages and RV pads, so garage conversions and junior ADU conversions of existing square footage are the dominant play, not new backyard construction. We work with prefab platforms including Abodu, Cover, and Mighty Buildings, and we also handle Tuff Shed-based conversions for budget-conscious homeowners. ADU Builders in Fontana covers the full scope, from foundation to finished kitchen.

Bathroom Remodeling in Fontana

Original bathrooms in Fontana’s 1950s and 1960s tract homes are small, often with a single vanity and a tub-shower combo that no longer works for a growing household. We open up layouts where the framing allows, replace cast-iron drain lines that have corroded over six decades, and add ventilation that handles Fontana’s dry heat. Bathroom Remodeling in Fontana walks through what a full remodel looks like in these older stucco homes.

Kitchen Remodeling in Fontana

Kitchen remodeling in Fontana usually starts with a 1950s – 1970s galley or L-shaped kitchen that was fine when the house was built but now feels closed off and underbuilt. The heat is part of the problem too: poor attic insulation and single-pane windows can make a Fontana kitchen uncomfortably warm by mid-afternoon, and old exhaust fans don’t move enough air during summer cooking. A remodel here should address the layout, the cooling, and the cabinetry at the same time. We bundle kitchen work with ADU construction or handle it as a standalone project, and we specify materials that hold up to a dry, hot climate. For a broader look at our approach, see Kitchen Remodeling.

Full Kitchen Remodels

Signs you need it

You have original cabinets with failing hinges, a layout that traps whoever is cooking away from everyone else, or a kitchen that can’t keep up with the way your Fontana household actually lives.

What it costs in Fontana

A full kitchen remodel in Fontana typically runs $40,000 to $70,000 depending on cabinet grade, countertop selection, and whether the scope includes structural or HVAC changes.

How we do it

We start with a site visit to measure existing conditions, confirm which walls can move, and check what insulation and electrical upgrades the house needs, then we produce a fixed quote and build the project in clear phases.

Kitchen Cabinet Refresh

Signs you need it

Boxes are still square but doors and drawer fronts are worn, or you need more accessible storage without redoing the entire kitchen footprint.

What it costs in Fontana

Expect $12,000 to $25,000 in Fontana for new doors, drawer fronts, hardware, and a refresh of exposed cabinet boxes.

How we do it

We inspect the existing boxes, order replacement fronts and hardware sized to your current cabinets, and install everything in a sequence that keeps your kitchen usable as long as possible.

Countertop and Backsplash Replacement

Signs you need it

You have cracked tile, dated laminate, or a countertop material that stains and burns too easily for the way you cook.

What it costs in Fontana

Replacing countertops and a basic backsplash in a Fontana kitchen typically runs $6,000 to $12,000 depending on material and linear footage.

How we do it

We template the exact dimensions after the old surface is out, cut and install the new material, and set the backsplash with proper seam placement and edge finishing.

How long does a kitchen remodel take in Fontana?

Do Fontana kitchen remodels need a permit?

Yes when we’re moving walls, changing plumbing or electrical, or altering the gas line. We handle permit drawings and inspections as part of the project. Call (844) 386-2399 for a free estimate on your Fontana kitchen.

What Fontana Customers Say

★★★★★ 5.0 from 4+ reviews

"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."

— Diego Delgado

"Knew the local setback and parking rules cold, which saved us from designing something that would never have been approved."

— Ebony Grant

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

— Sarah Kowalski
