ADU Company in Ontario, CA
Kitchen remodeling in Ontario usually costs between $28,000 and $65,000 for a full renovation, and the real variable is how far you go with layout changes in homes built between the 1980s and early 2000s. Ontario’s stucco-clad tract houses have predictable framing and utility runs, but that era also produced kitchens cut off from living space, with shallow pantries and dated lighting. Orchard ADU Builders has served Ontario since 2013, and we plan remodels that hold up to hot inland summers and the realities of a home where the kitchen carries daily family traffic. Call (844) 386-2399 for a free estimate on your Ontario kitchen.
Why Ontario Homes Are Different
Ontario’s housing stock is dominated by stucco and wood-frame single-family homes, mostly built from the 1980s through the early 2000s. These are tile-roofed, attached two-car-garage layouts on flat lots that drain toward the street, which works until winter rains pool against a slab edge that was never waterproofed at the kitchen door. The hot inland summers and occasional Santa Ana winds mean any remodel that adds glass without high-performance glazing will push the AC bill up, so we specify reflective roofing, deep overhangs where possible, and windows that actually block solar gain. In the 91762 and 91764 ZIP codes, many homes back up to shared block walls, and that changes how we route kitchen exhaust vents and where we can place a range hood. Ontario’s permit process is straightforward by Inland Empire standards, but HOA-governed tracts can add review time, so we verify CC&Rs before any drawings go to the city.
Our Main Ontario Services
Ontario homeowners call us about two things more than anything else: adding an ADU to a tract lot, and renovating a bathroom in a home that has not been touched since it was built. Each one has its own Ontario-specific realities, from HOA setback conflicts to shower waterproofing in stucco-era bathrooms.
ADU Builders in Ontario
Ontario’s wide side yards and deep backyards look ready for an ADU, but the late-1990s and early-2000s subdivisions often carry HOA CC&Rs that conflict with the city’s 4-foot setback minimums. We perform a pre-design feasibility audit before any plans are drawn, so you know exactly what your lot can support and what the HOA will actually approve. Garage conversions are the most common route here because the slab and utility stubs are already in place, though shallow footings from that building era usually need an engineering review before a habitable conversion can move forward.

Bathroom Remodeling in Ontario
Bathrooms in Ontario’s 1980s-to-early-2000s homes were built fast, with fiberglass tub surrounds, single vanities, and exhaust fans that vent into the attic instead of outside. That matters in a climate that swings from dry heat to winter rain, because trapped moisture is what turns a cosmetic refresh into a mold remediation project. We open walls, correct venting, waterproof properly, and bring these bathrooms up to current code while keeping the footprint workable for the average Ontario lot. Bathroom Remodeling in Ontario

Kitchen Remodeling in Ontario
A kitchen remodel in Ontario typically runs $28,000 to $65,000, and the spread comes down to whether you’re refreshing finishes in place or moving walls to open the kitchen to the living room. Homes here were framed with the kitchen as a separate room, so the most valuable change we make is usually removing a non-load-bearing wall or widening a pass-through to connect the space. Ontario’s hot summers also mean a remodel is the right time to upgrade ventilation and add glazing that cuts solar gain instead of amplifying it. We handle the full job, from the first layout conversation through cabinet installation and final inspection. It’s the same careful, brand-agnostic approach we bring to ADU builds, and it’s detailed on our Kitchen Remodeling page.
Cabinet Refacing and Replacement
Signs you need it
Your cabinet boxes are sound but the doors are delaminating, the hinges sag, and the layout no longer fits how your family cooks.
What it costs in Ontario
Cabinet refacing in Ontario typically runs $8,000 to $15,000, while full replacement runs $12,000 to $30,000 depending on linear feet and door style.
How we do it
We measure, order doors and hardware to match the existing boxes or the new layout, then install, align, and adjust every door and drawer for clean reveals.
Countertop and Backsplash Installation
Signs you need it
Laminate counters are burned at the edges, tile grout is failing, or you want a surface that handles daily use in a busy Ontario kitchen.
What it costs in Ontario
Quartz or granite countertops with a tile backsplash run $4,000 to $9,000 on a typical Ontario kitchen footprint.
How we do it
We template the existing cabinets, fabricate the stone off-site, then install and seal countertops and set the backsplash in one continuous pass.
What Kitchen Remodeling Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Full kitchen remodel (mid-range, 1980s-2000s home) | $28,000 – $45,000 |
| High-end kitchen remodel with layout change | $45,000 – $65,000 |
| Cabinet refacing | $8,000 – $15,000 |
What pushes the number up in Ontario is almost always structural: moving a load-bearing wall, relocating plumbing for a sink or gas line for a range, or rebuilding a kitchen floor that was never leveled correctly in the original build. We give fixed, line-item quotes before work starts, and the number on the quote is the number on the final invoice unless you ask us to change scope.
How long does a kitchen remodel take in Ontario?
A typical Ontario kitchen remodel takes 4 to 8 weeks, depending on whether we’re changing the layout or just replacing finishes. Custom cabinet lead times and countertop fabrication add the most schedule risk, so we order early. Call (844) 386-2399 for a timeline on your specific kitchen.
Do you pull permits for kitchen remodels in Ontario?
Yes. We pull permits whenever the scope requires them, and in Ontario any electrical, plumbing, or structural change will. We handle the drawings, the submittal, and the inspections so you’re not chasing the city. Call (844) 386-2399 and we’ll tell you what your project actually needs.
Brands We Service in Ontario
We work across the major prefab ADU platforms Ontario homeowners already research, including Abodu and Cover, plus traditional site-built construction. For exterior cladding on ADUs and additions, we specify James Hardie fiber-cement products because they handle Ontario’s heat and sun without the repainting cycle stucco requires. See our brands for the full platform list.

What pushes ADU costs up in Ontario specifically is HOA-driven setback revisions, engineering fixes for shallow garage footings, and soil conditions that occasionally demand deeper foundation work than the original tract build required. We price every project with a written, line-item quote before any work begins, so you know the full number up front.

FAQs About ADU Company in Ontario
Most Ontario projects start within 2 to 4 weeks of a signed estimate, depending on the city’s permit queue and HOA review timelines. Design-heavy ADU projects take longer because we run the feasibility audit first. Call (844) 386-2399 and we’ll give you a straight answer for your specific neighborhood.
Some do, and that’s exactly why we run a pre-design audit on every ADU in HOA-governed tracts. Ontario’s municipal code often allows a 4-foot setback, but an HOA’s CC&Rs can require more, and that gap is where projects stall. We resolve the conflict before plans are drawn, not after.

What Ontario Customers Say
"The kitchenette layout he suggested made better use of the space than the one on our original sketch."
— Christine Park"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."
— Diego Delgado"Knew the local setback and parking rules cold, which saved us from designing something that would never have been approved."
