ADU Company in Los Serranos, CA
Kitchen remodeling in Los Serranos means working on 1980s – 2000s Chino Valley tract homes where the original layouts are still in place: boxed-in galley kitchens, fluorescent soffits, laminate counters, and peninsula walls that cut the room off from the family space. Homeowners here typically want the wall opened up, the footprint expanded into a wide side yard, and cooling built into the plan because July and August regularly hit 95 – 100°F. We handle the full job, from wall removal and structural work to cabinets, counters, and finish, with one contractor from permit to punch-list. Call (844) 934-0236 for a free estimate.
Why Los Serranos Homes Are Different
Los Serranos sits on unincorporated San Bernardino County land, not inside Chino Hills city limits, which changes the permitting path on every project. Plans go through county Building and Safety instead of a city counter, and county zoning on these parcels carries its own setback and lot-coverage requirements. Homeowners frequently assume they need city approval, and they don’t. That county process affects kitchen remodels too, especially on the older ranch parcels along the Los Serranos corridor where original floor plans are simpler but foundations and framing may be less predictable than the newer two-story tract stock.
The housing inventory is dominated by 1980s – 2000s tract homes on generous lots. Those wide side yards and rear setbacks are real advantages: they give us room to expand a kitchen outward without touching the second story, and they make detached builds easier to place. The summer heat shapes material decisions. Inland San Bernardino County’s dry, hot climate means kitchens with poor ventilation turn into heat sinks, so window placement, range-hood ducting, and even cabinet finish take on more weight here than they would in a coastal city.
Our Main Los Serranos Services
Los Serranos homeowners call us most often about two things: adding an ADU to a lot that’s permitted through the county, and updating bathrooms in homes that haven’t been touched since the original build. Both jobs share the same local conditions, from county plan-check paths to heat-conscious material choices.
ADU Builders in Los Serranos
Building an ADU on unincorporated county land means a plan-check process that’s different from neighboring Chino Hills, and that’s where most Los Serranos homeowners get tripped up. We work across eight manufacturers, including Abodu, Cover, and Tuff Shed, so the unit we recommend depends on your lot’s setbacks, your budget, and whether the county’s lot-coverage rules leave room for a detached build or push you toward a conversion. We handle the county submittal, the foundation or slab work, the unit delivery or framing, and the interior finish. ADU Builders in Los Serranos covers the full scope.
Bathroom Remodeling in Los Serranos
Most tract bathrooms in 91709 were built with fiberglass tub-shower combos, single vanities, and tile that’s now dated or cracked at the grout lines. The conversion from tub to walk-in shower is the most requested change, especially in homes where an aging family member lives. We also fix the ventilation problems that show up as peeling paint and mildew in the dry-heat climate, because a bathroom that can’t move air stays damp even when it’s hot outside. Bathroom Remodeling in Los Serranos has the full breakdown.

Kitchen Remodeling in Los Serranos
Kitchen remodeling in Los Serranos usually starts with one of two frustrations: a galley kitchen that isolates the cook from family and guests, or a layout that’s been patched for 20 years with mismatched appliances and failing cabinet boxes. The 1980s – 2000s tract homes here have a predictable set of problems: fluorescent soffits, thin cabinet doors with worn hinges, laminate counters that scorch and chip, and a single oven-and-cooktop setup that can’t keep up with a household that’s grown. The wide side yards on most lots give us room to expand the kitchen footprint without a second-story addition, which keeps most remodels attached-to-structure rather than a bump-out into the rear setback. County permitting applies, and we pull those permits for you. For a deeper look at how we approach the work, visit our Kitchen Remodeling hub.
Full Gut Kitchen Remodel
Signs you need it
The cabinet frames are pulling away from the wall, the floor dips near the sink, and patching another section of drywall won’t fix the layout.
What it costs in Los Serranos
In Los Serranos, a full gut kitchen remodel typically runs from $38,000 to $75,000 depending on appliance grade, cabinet construction, and whether we’re moving plumbing or gas lines.
How we do it
We strip the room to studs, replace any water-damaged framing, move plumbing and electrical per the new layout, then rebuild with new cabinets, counters, flooring, and finish.
Open-Concept Kitchen Expansion
Signs you need it
You can’t see the kids or the TV from the sink, and every gathering ends up with people crammed into the family room while the cook works in isolation.

Removing a load-bearing wall and opening the kitchen to the living space runs $18,000 to $35,000 in Los Serranos when we’re keeping the existing footprint and adding a flush beam.
How we do it
We shore the ceiling, install a structural beam sized for the span, reroute any electrical or plumbing in the wall, then patch and finish the opening so the two rooms read as one.
Cabinet and Countertop Replacement
Signs you need it
Doors are delaminating or won’t close square, and the laminate counters have burns, chips, or water damage at the seams.
What it costs in Los Serranos
Cabinet and countertop replacement in Los Serranos typically falls between $12,000 and $28,000 for a mid-size kitchen, depending on whether you choose stock, semi-custom, or fully custom cabinetry and quartz versus stone slab.
How we do it
We measure and order cabinets and templated counters, remove the old boxes and tops, install new cabinets level and anchored to studs, then set the counters and reconnect plumbing.

What Los Serranos Customers Say
"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."
— Heather Ackerman"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 Castillo"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."
