ADU Company in Fontana, CA
Kitchen remodeling in Fontana usually means working inside a 1950s to 1980s tract home where the original footprint, plumbing, and electrical panel were never designed for what today’s families need. Between summer temperatures that regularly pass 100°F and older slab-on-grade construction, the job here is as much about correcting outdated infrastructure as it is about new cabinets and countertops. Sunburst ADU Builders handles the full interior fit-out, which means your kitchen remodel and any attached ADU work stay under one contract. Call (855) 676-6807 to schedule a free estimate.
Why Fontana Homes Are Different
Fontana’s housing stock runs heavily to post-WWII and mid-century tract homes: wood-frame stucco on slab foundations, many with detached two-car garages set on lots that feel generous compared to what you find closer to Los Angeles. That matters for two reasons. First, the typical home in 92335 and 92336 was wired for a 60-amp or 100-amp panel, which kitchen remodel permits now flag for upgrade when you add cooktops, double ovens, or dedicated circuits. Second, slab-on-grade construction means moving a sink or adding a gas line means cutting concrete, not crawling under a raised floor. The cost and timeline shift accordingly.
The climate shapes material choices more than most homeowners expect. Fontana sits in the hot, dry Inland Empire, with Santa Ana winds pushing through the foothills on the north side. We specify finishes that hold up to heat and low humidity without warping or fading, and we pay close attention to ventilation and cooling load when a kitchen opens into a new ADU space. On older north-side streets near the foothills, fire-resistant materials and proper clearance matter when we run exterior venting or add a range hood. These are not abstract concerns; they show in the quote and the permit package.
Our Main Fontana Services
Two services account for most of the calls we take in Fontana: full ADU construction and bathroom remodeling. Both tie back to the same local reality: older homes with a lot of potential but outdated mechanical and structural pieces that need attention before finish work begins.
ADU Builders in Fontana
Fontana’s ADU market is family-driven. Across 92335 and 92336, we see detached garages converted into casitas for aging parents and adult children far more often than investor spec rentals. Many of those garages had informal, unpermitted conversions done years ago, which means the real work is legalizing, upgrading, or replacing what is already there. Seismic bracing, utility trenching, and panel upgrades carry the weight. As a manufacturer-agnostic builder, we compare prefab, modular, and custom approaches against your lot, budget, and the city’s expedited plan-check process. ADU Builders in Fontana covers that service in depth.
Bathroom Remodeling in Fontana
Bathroom remodels in Fontana frequently run into the same 1950s to 1970s bathroom footprint: small, single-sink layouts with cast-iron or galvanized drain lines that have been in the ground for half a century. When we open a wall, we often find the sewer lateral and venting need work before the new tile goes in. Add the Inland Empire heat and hard water, and we lean toward finishes and fixtures that stand up to mineral buildup and temperature swings. Bathroom Remodeling in Fontana has the full scope for that service.

Kitchen Remodeling in Fontana
A Fontana kitchen remodel is usually not a cosmetic refresh. It is a rework of a 50-to-70-year-old room whose plumbing, wiring, and layout predate dishwashers, vented ranges, and islands. In 92334 through 92337, the typical scope opens with panel capacity and slab cutting, then moves into cabinetry, counters, ventilation, and finish plumbing. Our full-scope approach means the kitchen is finished by the same crew that would handle a connected ADU interior, under one contract. For a broader look at how we approach this service, see our Kitchen Remodeling hub.
Cabinet Replacement and Layout Rework
Signs you need it
Doors that no longer close square, shelving that bows under normal dish loads, or a layout that traps two cooks in a single 36-inch aisle are the usual signals.
What it costs in Fontana
Cabinet replacement and moderate layout rework in Fontana typically runs $18,000 to $38,000 depending on cabinet line, layout changes, and whether the slab must be cut to move plumbing.
How we do it
We measure the existing footprint, map the plumbing and electrical changes, order cabinets to the revised layout, then install and align everything after the rough-in work passes inspection.
Countertop, Backsplash, and Appliance Upgrade
Signs you need it
Chipped laminate edges, stained grout lines, a cooktop or oven that no longer holds temperature, or a dishwasher so loud it ends conversation are the practical triggers.
What it costs in Fontana
This scope in Fontana usually lands between $6,000 and $15,000, with stone or engineered stone counters and a tile backsplash representing the bulk of the material cost.
How we do it
We template the counters after the base cabinets are set, cut and install the stone, run the backsplash, then connect and test each appliance with the upgraded circuits and venting in place.
What Kitchen Remodeling Costs in Fontana
| Item | Typical range in Fontana |
|---|---|
| Cabinet replacement and layout rework | $18,000 – $38,000 |
| Countertop, backsplash, and appliance upgrade | $6,000 – $15,000 |
| Full kitchen remodel with panel and mechanical upgrades | $35,000 – $70,000 |
What pushes the number up in Fontana is not usually the finishes. It is the hidden infrastructure: a 60-amp panel that needs replacing, a cast-iron drain line under the slab that has failed, or moving a gas line across a concrete floor. We price the known conditions up front and walk you through what we find before any change order becomes a conversation.
How long does a kitchen remodel take in Fontana?
Most Fontana kitchen remodels run 4 to 8 weeks from demo to final cleaning. Homes needing panel replacement, slab cutting for plumbing moves, or asbestos abatement on older flooring run longer, and the city’s inspection schedule can add a week in peak season. Call (855) 676-6807 for a timeline tied to your specific scope.
Will the price change once work starts?
Only if we uncover a condition we could not see during the site walk, such as a cracked sewer lateral or a buried junction box. We document everything before we start and write change orders in plain language with line-item pricing, so you approve the number before we proceed.
Brands We Service in Fontana
Because we are manufacturer-agnostic, the brand decision follows the lot and the budget, not the other way around. In Fontana we regularly work with Mighty Buildings, Plant Prefab, and Tuff Shed conversions, and we stock common trim, flashing, and James Hardie siding components locally to keep lead times from drifting.

FAQs About ADU Company in Fontana
Yes. Every job we take goes through the city’s permit process, and we handle the drawings, submittals, and inspections ourselves. That matters especially for garage conversions, where Fontana’s expedited plan-check is built around legalizing or replacing older unpermitted work, not hiding it. Call (855) 676-6807 to talk through your specific property.
Most projects move from signed contract to permit submittal within two to three weeks, and the city’s review timeline then sets the start date. Kitchen remodels and garage conversions tend to permit faster than new detached ADUs. We schedule estimates across Fontana the same week you call.

What Fontana Customers Say
"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Hector Torres"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."
— Jodi Reed"He was honest that our lot had a slope problem that would add real cost, before we signed anything."
— Katie Parker
