ADU Company in Fontana, CA

Kitchen remodeling in Fontana usually means reworking a kitchen inside a post-war tract home or a late-20th-century stucco house, where the original footprint was built for a different era of cooking and family life. We’re Newport Beach ADU Builders, and we’ve been serving Fontana since 2016, handling kitchen remodels alongside ADU construction so homeowners don’t have to coordinate two separate contractors. Our Fontana kitchen work focuses on the realities of inland heat, older electrical panels, and floor plans that need real structural thought before cabinets go in. Call (844) 934-0236 to talk through what your kitchen needs.

Why Fontana Homes Are Different

Fontana’s housing stock is dominated by post-war and late-20th-century single-family tract homes. You’ll see modest ranches and two-story stucco houses on generous lots, with older neighborhoods near the historic core and newer subdivisions pushed toward the north and east. Those older homes, many built between the 1950s and 1990s, were framed before open-concept kitchens became standard. Walls separate the kitchen from living space, ceilings sit lower, and electrical panels often max out at 100 amps, which is not enough for a modern kitchen with induction cooktops, double ovens, and dedicated appliance circuits.

Fontana sits east of the Cajon Pass, where summer temperatures routinely top 100°F and Santa Ana winds sweep through in the fall. That heat changes how we spec ventilation, range hood CFM, and even cabinet materials, because cheap laminates can delaminate in an unconditioned house during July. The flat, wide lots throughout Fontana give us room to work, but the older service panels and single water meters on those same homes are the real bottleneck. A kitchen remodel here often starts with a panel upgrade and re-piping before we ever touch a countertop.

We work in ZIP codes 92334, 92335, 92336, and 92337, and the homes we see most are in Southridge, the older blocks around City Hall, and the newer subdivisions east of Sierra Avenue. Each area has its own quirks, but the common thread is this: these houses were built well, they just were not built for the way people cook now.

Our Main Fontana Services

Fontana homeowners usually call us about two things: adding an ADU to a flat backyard, or gutting and rebuilding a bathroom inside the main house. Both jobs live under one roof with us, which means one permit path, one schedule, and one person to call when something needs attention. Here is how each one works in Fontana.

ADU Builders in Fontana

Fontana is one of the Inland Empire’s strongest ADU markets because the large lots of single-family tract homes leave room for detached backyard units where coastal LA cities have no space left. The city’s zoning and state law now make it one of the few places in Southern California where a homeowner can realistically add a rentable second home. The catch is that many Fontana homes still run on older 100-amp panels, and a detached ADU usually needs its own subpanel plus trenching for utilities across the yard. We handle that as part of the build. ADU Builders in Fontana

Bathroom Remodeling in Fontana

Older Fontana bathrooms are small, often 5 by 8 feet or less, with tile set on mud beds that have cracked over decades of hot, dry summers. We see a lot of failing shower pans and outdated plumbing stacks in homes built before the 1980s. Remodeling here means working around cast-iron drain lines that need replacing, tight stud bays that limit insulation, and the same panel constraints we see in kitchens. We pull permits, replace the old plumbing, and rebuild the room to handle inland heat and daily use. Bathroom Remodeling in Fontana

Kitchen Remodeling in Fontana

A kitchen remodel in Fontana typically costs between $35,000 and $85,000 depending on the home’s age, whether walls come down, and how much electrical work the panel needs. Older tract homes in Fontana often hide surprises behind the drywall: undersized wiring, no dedicated appliance circuits, and cast-iron drain lines that are past their service life. The heat matters here too, because an under-vented kitchen in a Fontana summer turns into a room nobody wants to cook in. We plan remodels around airflow, panel capacity, and the way these 50- to 70-year-old houses are actually framed. If you want to see the bigger picture on what we do, our Kitchen Remodeling overview covers the full approach, but the Fontana specifics are below.

Cabinet Replacement and Layout Changes

Signs you need it

Soft-close drawers that no longer close, delaminated cabinet boxes, or a layout that puts the refrigerator against the only workable counter run.

What it costs in Fontana

Cabinet replacement and layout reconfiguration in Fontana runs $20,000 to $45,000 depending on whether walls move and whether we’re replacing a galley or an L-shaped layout.

How we do it

We measure the existing footprint, check load-bearing walls and plumbing locations, then order cabinets sized for the actual room rather than forcing a standard layout into a 1960s floor plan.

Countertop and Backsplash Replacement

Signs you need it

Cracked tile, stained grout that won’t come clean, or laminate countertops that have bubbled from heat and moisture over decades of Fontana summers.

What it costs in Fontana

Countertop and backsplash replacement in Fontana runs $5,000 to $12,000, with quartz and natural stone at the higher end and solid-surface materials below that.

How we do it

We template the existing cabinets, shim and level the base, then install the new counter and backsplash with expansion gaps sized for inland temperature swings.

What Kitchen Remodeling Costs in Fontana

Item Typical range in Fontana
Full kitchen remodel $35,000 – $85,000
Cabinet replacement and layout changes $20,000 – $45,000
Countertop and backsplash replacement $5,000 – $12,000

What pushes a kitchen remodel up in Fontana is almost always the panel and plumbing. If we need a 200-amp upgrade plus trenching for a new gas or drain line, that’s added cost before a single cabinet is ordered. We price that in writing up front so the number on the estimate is the number you pay.

How long does a kitchen remodel take in Fontana?

A full kitchen remodel in Fontana typically takes 6 to 10 weeks from demolition to final inspection. Lead time on custom cabinets adds 4 to 6 weeks before demo starts, and we coordinate that ordering while permits clear. Call (844) 934-0236 for a schedule based on your exact scope.

Do you pull permits for kitchen remodels in Fontana?

Yes. We pull city permits for every kitchen remodel in Fontana, including electrical, plumbing, and structural changes. Fontana’s building department requires permits when walls move or panel capacity changes, and we handle that paperwork as part of the job. Call (844) 934-0236 for an exact quote, estimates are free.

Brands We Service in Fontana

We work with the brands Fontana homeowners have already been researching: Abodu and Cover for design-forward prefab ADUs, Tuff Shed for budget-conscious backyard conversions, and James Hardie fiber-cement siding for exteriors built to take inland sun and wind. Parts and materials are ordered direct from each manufacturer, which keeps turnaround predictable. Our brands page lays out the full roster.

Pricing for ADU Company in Fontana, CA

Service Typical range in Fontana
Full kitchen remodel $35,000 – $85,000
Cabinet replacement and layout changes $20,000 – $45,000
Countertop and backsplash replacement $5,000 – $12,000

In Fontana, two things push costs higher than they look on a coastal estimate: panel capacity and trenching distance. Older homes on big lots mean longer utility runs from the main structure to an ADU or a new kitchen addition, and digging across a 60-foot backyard in hard, dry soil costs real money. Everything we bid is a fixed price with a written line-item breakdown, and we do not issue change orders unless you ask for a scope change.

Neighborhoods We Serve in Fontana

We work across all of Fontana, from the older blocks near downtown to the newer subdivisions on the north and east edges. Here are the neighborhoods we’re in most often:

  • Southridge
  • Downtown Fontana and the historic core
  • Walnut Village
  • Summit Heights
  • Northgate and the newer tracts north of the 210

In most of Fontana we can get someone out for a site visit within a few business days of your call. Scheduling is tightest in spring and fall, when the heat is manageable and everyone wants work done before the summer spike.

What Fontana Customers Say

★★★★★ 4.8 from 4+ reviews

"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."

— Malik Nash

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

— Steven Nguyen

"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."

— Heather Ackerman
