ADU Company in Ontario, CA
Kitchen remodeling in Ontario means working around mid-century stucco homes with original layouts, heavy summer heat that warps cheap materials, and a city where multi-generational households are the norm rather than the exception. Bungalow ADU Builders handles kitchen remodels as a core service, not a side job, and we’re familiar with the specific ways Inland Empire heat and Santa Ana dust affect cabinetry, flooring, and ventilation choices. Call (866) 730-4828 to schedule a free estimate.
Why Ontario Homes Are Different
Ontario sits directly in the path of Santa Ana winds funneling through the Cajon Pass, which means backyard structures and exterior details take a beating that coastal cities never see. Summer temperatures routinely exceed 100°F, and the combination of heat and wind-driven dust means an ADU shell, its roof edges, and its exterior cladding need to be specified for endurance, not just appearance. We see this on nearly every job in the older central neighborhoods around 91761, 91762, and 91764, where mid-century single-story homes sit on lots large enough for a detached unit but were built when insulation standards were far looser than today’s Title 24 requirements.
The housing stock here is a mix of original 1950s and 1960s stucco tract homes with generous backyards and newer infill construction near the city’s edges. Many of those older homes still run 100-amp electrical panels, and adding a detached ADU with its own kitchen and mini-split system often means upgrading the main service before the unit can pass inspection. Ontario’s zoning and setback rules are workable for detached backyard ADUs on the deep lots common in the older core, but every project still needs a careful lot-coverage calculation. We handle that math as part of our normal estimating process.
The social pattern here shapes the work too. A large share of Ontario ADU projects are casitas for aging parents or adult children, not pure rental plays. That changes the interior conversation: wider door clearances, zero-threshold showers, and kitchens sized for daily cooking rather than tenant turnover. Bungalow ADU Builders has served Ontario since 2014, and we’ve learned to plan for these family-driven layouts from the first site visit.
Our Main Ontario Services
Most Ontario homeowners call us about one of two projects: a detached ADU in the backyard, or a bathroom remodel that makes an existing home or a new unit genuinely livable.
ADU Builders in Ontario
An ADU in Ontario is a different animal than one in a coastal city. The heat, wind, and dust load on the exterior means we select cladding and roof details that hold up to Santa Ana events, and the older panel situation on many central Ontario homes means electrical scope gets priced honestly up front. We’re brand-agnostic, sourcing from manufacturers like Abodu, Dvele, and Plant Prefab so the product fits the lot and budget, not the other way around. Learn more on our dedicated ADU Builders in Ontario page.
Bathroom Remodeling in Ontario
Bathroom remodels here often run into hard water from the local supply, which shortens the life of cheap fixtures and builds scale inside shower valves. Ontario’s older homes also tend toward small original bathrooms, so we spend real time on layout changes that add usable space without moving plumbing stacks. Whether it’s a primary bath refresh or converting a half bath into a full one for an ADU, we handle it in-house. See our Bathroom Remodeling in Ontario page for the full scope.

Kitchen Remodeling in Ontario
Kitchen remodeling in Ontario often starts with a homeowner frustrated by an original 1960s layout: closed off from the dining room, short on counter space, and built with materials that have spent fifty years absorbing Inland Empire heat. The specific problem we solve here is a kitchen that works for a multi-generational household in a climate where cheap laminate and thin cabinet boxes fail early. We offer Kitchen Remodeling as a full-scope service, from demo through finished millwork, with the same team that builds ADU interiors handling the work.
Full Kitchen Renovation
Signs you need it
Your kitchen still has the original footprint from when the house was built, cabinet doors no longer close square, and the layout cuts the cook off from everyone else in the house.
What it costs in Ontario
A full kitchen renovation in Ontario typically runs from $25,000 to $60,000 depending on cabinet grade, countertop material, and whether walls or plumbing move.
How we do it
We demo to the studs, correct any framing or drywall issues, run new electrical and plumbing rough-in, hang and finish drywall, install cabinetry and countertops, then handle flooring, backsplash, and fixtures through final paint.
Cabinet Refacing and Hardware Update
Signs you need it
Your cabinet boxes are structurally sound but the doors and drawer fronts are dated, worn, or the wrong color for a home being prepared for an ADU-adjacent refresh.
What it costs in Ontario
Cabinet refacing in Ontario usually falls between $7,000 and $16,000, a fraction of full replacement because the boxes stay in place.
How we do it
We remove existing doors and drawer fronts, apply new veneer or paint to the boxes, install new doors, fronts, and soft-close hardware, then align and adjust every opening.
What Kitchen Remodeling Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Full kitchen renovation | $25,000 – $60,000 |
| Cabinet refacing and hardware | $7,000 – $16,000 |
| Countertop replacement | $4,000 – $12,000 |
Heat and hard water push prices toward the upper end of these ranges when a home needs extra plumbing work or when a panel upgrade is required to support modern appliances. We give written line-item quotes before work starts, so the number we agree on is the number you pay.
How long does a kitchen remodel take in Ontario?
A full kitchen remodel in Ontario typically takes 6 to 10 weeks from demo to final walkthrough; cabinet refacing runs 2 to 3 weeks. Call (866) 730-4828 for a schedule based on your exact scope.
Do you pull permits for kitchen work in Ontario?
Yes, we pull all required city permits for electrical, plumbing, and structural changes, and we schedule the inspections. Estimates are free, so call (866) 730-4828 to confirm what your project needs.

What Ontario Customers Say
"Garage conversion to a one bedroom unit. He handled the plans, the city submittal, and every round of corrections. Took six months from first meeting to final inspection and he never once made the permit process my problem."
— Wade Pruitt"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."
— Emily Yang"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."
— Alicia Ingram
