ADU Company in Rialto, CA
Kitchen remodeling in Rialto almost always means working inside a 1950s or 1960s tract home where the original layout was built for a different era of cooking and gathering. Homeowners here call us when the galley kitchen feels too tight, the cabinets are original, and the summer heat makes an under-insulated kitchen unbearable by 4 p.m. Sunstone ADU Builders handles the full kitchen scope, from structural changes to finishes, so you’re not coordinating a separate cabinet crew and countertop installer. Call (855) 949-1913 to talk through what your Rialto kitchen could become.
Why Rialto Homes Are Different
Rialto’s housing stock is dominated by post-war tract homes built between the 1950s and 1970s. Most are single-story stucco with detached garages set far back on generous lots. That layout matters when you’re planning kitchen work: the original kitchens were often compact, closed-off rooms with poor sightlines to the backyard, and the plumbing and electrical were sized for appliances that drew far less power than today’s induction ranges and double ovens. Many Rialto homes still run on panels that need upgrading before a serious kitchen remodel can pass inspection.
The climate shapes decisions too. Rialto sits in the hot, dry Inland Empire with summer highs routinely over 100°F. A kitchen remodel here isn’t just about countertops; it’s about ventilation, insulation in exterior walls, and window placement that doesn’t turn the afternoon sun into an oven. Homes west of Riverside Avenue often sit on flat, clay-heavy soil that expands and contracts with moisture, which means we pay attention to how slab movement might affect a new island with plumbing. Those are exactly the conditions we plan for on every Rialto job.
Our Main Rialto Services
Rialto homeowners reach out to us most often for two big projects: building an ADU on their large lot, and bringing a dated bathroom up to something the family actually wants to use. Both start with a free site visit and an honest conversation about what the property can support.
ADU Builders in Rialto
Rialto’s large lots and detached garages make it one of the most practical cities in San Bernardino County for adding an accessory dwelling unit. Many of the garages we look at were built in the 1960s and need slab and header work before conversion makes sense. We build both prefab units from brands like Abodu and Cover and traditional stick-built ADUs, and we handle the permits, utility connections, and interior finishes under one contract. See what’s possible on your lot: ADU Builders in Rialto.

Bathroom Remodeling in Rialto
Bathrooms in Rialto’s original tract homes were built small, with a single vanity and a tub-shower combo that hasn’t aged well. Owners ask us to open up the footprint, add ventilation that actually moves humid air, and finish with materials that hold up to heat and hard water. We scope bathroom work to ADU interiors and companion remodels on the primary residence, so the same crew that frames your ADU can also finish its bathroom. Details are on our Bathroom Remodeling in Rialto page.

Kitchen Remodeling in Rialto

In Rialto, most kitchen remodels are about undoing sixty years of decisions that made sense at the time but don’t anymore. The closed-off galley layout, the single overhead light, the lack of a vent hood that actually vents outside – these are all standard in 1950s-1970s tract homes here, and all of them make a kitchen feel smaller and hotter than it is. Our kitchen work runs from partial updates to full layout changes, with the same crew handling structure, plumbing, electrical, cabinetry, and finishes. If you’re comparing approaches, our Kitchen Remodeling overview covers scope and options in detail.

We demo to the studs, upgrade electrical and plumbing as needed, reframe for the new layout, then install insulation, drywall, cabinetry, countertops, appliances, and finish with paint and trim.
Kitchen Cabinet Refacing
Signs you need it
Your cabinet boxes are solid but the doors and drawer fronts are worn, dated, or the finish is peeling from years of Inland Empire heat.
