ADU Company in Fontana, CA
Kitchen remodeling in Fontana means working with homes built between the 1950s and 1990s, where original layouts were designed for a different era. Most kitchens in Fontana’s stucco tract homes are closed off from living spaces, built around dated peninsula counters, and lack the ventilation needed for summers that routinely cross 100°F. Add in aging electrical panels and sewer lines in older 92335 stock, and a kitchen remodel here is rarely just about cabinets and countertops. That’s exactly the kind of job Costa Mesa ADU Builders takes on: full-scope kitchen work, tied into the same contract as your ADU or bathroom remodel, with no second contractor handoff.

Why Fontana Homes Are Different
Fontana is one of the strongest ADU markets in San Bernardino County because its vast inventory of post-WWII and 1960s-80s single-story stucco homes on large lots across ZIPs 92335, 92336, and 92337 sit on flat, wide parcels where a detached ADU or garage conversion usually fits without a variance. But the city’s prevailing lot widths and the many homes with rear alley access mean the design conversation is almost always about where to place the unit and which driveway or alley serves it, not whether it’s allowed.
The housing stock also shapes interior work. Homes here are largely one-story with attached two-car garages and generous backyards. Older stock in 92335 often has detached or substandard garages, lightly built additions, and aging sewer laterals and electrical panels that must be addressed before any ADU or major interior remodel can be permitted. A kitchen remodel in a 1960s Fontana home frequently uncovers aluminum wiring or a 60-amp panel that cannot support modern appliances without an upgrade. These are not surprises to us; they are the first things we check.
Climate is the other constant. Fontana sits in the hot, dry Inland Empire east of the Cajon Pass. Summer highs regularly exceed 100°F, Santa Ana winds put real stress on roof and patio connections, and low-slope roofs on older homes collect heat in ways that make unconditioned additions miserable. Any ADU, kitchen, or bathroom project here must account for cooling capacity, window placement, and insulation choices. We design for that reality from day one.
Our Main Fontana Services
Two services account for most of the calls we get from Fontana homeowners: ADU construction and bathroom remodeling. Both benefit from the same full-scope approach, which keeps structural work and interior finishes under one contract.
ADU Builders in Fontana
Fontana’s large lots and rear-alley access make it a natural fit for detached ADUs, and the math usually works whether your goal is rental income or a multigenerational suite. We bring the multi-brand prefab advantage to the conversation: comparing Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, and Tuff Shed against site-built options, so the recommendation fits your actual lot and budget. Older 92335 garages being converted often need framing or slab corrections before permits clear; we handle that scope. ADU Builders in Fontana has the full breakdown.
Bathroom Remodeling in Fontana
Fontana bathroom remodels in 1950s-1980s homes often start with cast-iron drain lines that have reached the end of their service life, and older 92335 properties sometimes have slab leaks or failing subfloors behind the tile. We replace what needs replacing, then build the bathroom you actually want: walk-in showers, freestanding tubs, dual vanities, and ventilation rated for Inland Empire heat. Since we also build ADUs, we can tie a primary-bath remodel into the same project phase as a new unit. Bathroom Remodeling in Fontana covers the details.

Kitchen Remodeling in Fontana
Kitchen remodeling in Fontana usually starts with a house built before open-concept living existed. The original kitchen is walled off, under-ventilated, and wired for appliances that draw a fraction of what today’s induction ranges, double ovens, and beverage fridges demand. The payoff is real, especially for homeowners also adding an ADU: a remodeled kitchen in the primary house raises the property’s long-term value while the ADU generates income. Our in-house kitchen team handles everything from layout and cabinetry to countertop fabrication and appliance installation, so your new ADU and refreshed home stay under a single contract.

What pushes a Fontana ADU or remodel toward the top of these ranges is usually site correction: an older 92335 garage that needs slab replacement, a 60-amp panel that must be swapped for 200-amp service, or sewer lateral work before any interior plumbing moves. We quote those items as fixed line items before work starts, and we do not issue change orders for conditions we should have caught in planning.

FAQs About ADU Company in Fontana
Most Fontana projects start within 2 to 4 weeks for interior remodels and 4 to 8 weeks for ADUs that need design and permitting. Timing depends on permit queue at the City of Fontana and whether your home needs panel, sewer, or slab corrections first.
Some Fontana neighborhoods, especially newer 92336 and 92337 tracts, have HOAs with architectural review requirements. State ADU law limits what HOAs can prohibit, but design approval and placement rules still matter. We handle HOA submittals as part of our scope.
We manage the entire project under one contract. Structural work, utilities, flooring, cabinetry, tile, and finish carpentry are coordinated by one project lead. For prefab ADUs, we handle site prep, utility connection, and all interior finishes after the unit is set.

— Ryan Padgett"He gave us a realistic rental number for the finished unit rather than the optimistic one, and it's renting for about what he said."
— Andres Rodriguez"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."
