ADU Company in Fontana, CA
Kitchen remodeling in Fontana is our most-requested service, and it looks different here than it does closer to the coast. The dominant housing stock is 1970s-to-2000s stucco tract homes with tile roofs and attached two-car garages, and kitchens in these houses were built for a different era: small islands or none, builder-grade oak cabinets, fluorescent soffits, and layouts that cut off the cook from the rest of the house. Fontana summers routinely push past 100°F, so ventilation, heat-tolerant finishes, and HVAC-aware design matter more than they would in a milder climate. If you’re weighing an ADU, a kitchen remodel, or a bathroom refresh, call Camden ADU Builders at (844) 747-5499 and we’ll give you an honest read on scope and cost.
Why Fontana Homes Are Different
Fontana is a working-class Inland Empire city where most of the housing stock was built between the 1970s and early 2000s. The lots are generous – commonly 6,000 to 8,000 square feet – but the homes themselves were framed to a production-tract standard: stucco exteriors, tile roofs, long side-yard setbacks, and rear yards that have historically been ornamental rather than functional. That flat, open rear yard is the single biggest opportunity for a detached ADU, but it comes with site realities that a contractor from outside the area won’t anticipate. Block walls are the default boundary between properties in the 92335, 92336, and 92337 ZIP codes, and those walls often define rear-alley or side-yard access routes that become the real bottleneck during construction, not the unit design itself.
The climate shapes the work too. Summer heat regularly exceeds 100°F, and the Santa Ana winds that sweep through the Cajon Pass bring strong afternoon sun and dry air that punishes cheap materials. Flat and low-slope roofs on detached units need assemblies that handle intense UV exposure and occasional heavy winter rain. Fontana’s HOA and CC&R landscape sits on top of San Bernardino County and city permitting, which means ADU projects behind existing tract homes almost always require a careful read of the governing documents before the first plan is drawn. This is second-generation infill work, and the homes that rise to the top of the rental market here are the ones designed for the heat, the wind, and the block-wall lot lines.
Our Main Fontana Services
Fontana homeowners call us about two projects more than anything else: building an ADU in the rear yard or above the garage, and remodeling a bathroom in an aging tract home. Both require the same eye for local permitting and climate realities.
ADU Builders in Fontana
Detached ADUs and garage conversions are the dominant format in Fontana because the lots are deep and flat, and the block walls already define the buildable envelope. We walk each property with the rear-access question in mind, because that dictates equipment access and material staging more than the unit footprint does. From Tuff Shed conversions at the budget end to Mighty Buildings and Plant Prefab at the premium modular end, we match the build path to your lot, your budget, and your timeline.

Bathroom Remodeling in Fontana
Bathrooms in Fontana’s 1980s and 1990s tract homes are small, often windowless, and built with materials that struggle in a semi-arid climate. We open up shower footprints, replace fiberglass surrounds with tile systems that handle temperature swings, and add ventilation that actually moves air. For homeowners adding an ADU, we also finish the ADU bathroom under the same roof, so the shell and the interior never get passed between two contractors. Bathroom Remodeling in Fontana.

Kitchen Remodeling in Fontana
Kitchen remodeling in Fontana means working inside a specific housing era. Most kitchens we open up are in 1970s-to-2000s stucco tract homes with original layouts: a peninsula or no island at all, a soffit box above the cabinets, and a floor plan that walls the cook off from the living space. Removing those soffits, reworking the footprint to add a proper island, and upgrading ventilation for a kitchen that has to survive 100°F summers is the core of the work. We also finish ADU kitchens under the same contractor relationship, so if you’re building a unit in the rear yard and remodeling the main house, one crew handles both. For a deeper look at how we approach the work, see Kitchen Remodeling.
Full Kitchen Gut and Reconfiguration
Signs you need it
The layout fights you every day – no landing space next to the range, a peninsula that blocks traffic, cabinets that don’t hold modern cookware, and original 1980s or 1990s appliances that are failing one by one.
What it costs in Fontana
A full kitchen remodel in Fontana typically falls between $45,000 and $85,000 depending on cabinet grade, countertop material, and whether we move plumbing or electrical.
How we do it
We demo to the studs, reroute plumbing and electrical for the new layout, frame any structural changes, then install cabinets, counters, tile, lighting, and appliances in sequence with inspections at each required stage.
ADU Kitchen Finish-Out
Signs you need it
The ADU shell is up or the prefab unit is delivered, but the interior kitchen is an open question – no cabinets, no counters, no appliances, and no clear plan for making it livable.
What it costs in Fontana
ADU kitchen finish-outs in Fontana run $18,000 to $38,000 for a compact, efficient kitchen with mid-range cabinets, quartz counters, a cooktop, and a refrigerator line.
How we do it
We take measurements off the delivered or framed unit, order cabinets and counters to fit, install the full kitchen, and handle the appliance hookups so the unit passes final inspection.

Will my kitchen remodel work with a Fontana HOA?

Brands We Service in Fontana
We work with Mighty Buildings, Boxabl, and Plant Prefab among our prefab partners, and Tuff Shed structures as a cost-accessible conversion path.
