ADU Company in Highland, CA
Kitchen remodeling in Highland means working inside homes built between the 1950s and 1970s, where original layouts, dated electrical panels, and decades of inland heat have taken a toll. We’re Westminster ADU Builders, and while ADUs are our core business, we also rebuild Highland kitchens with the same team that handles our accessory dwelling unit projects. That matters because a kitchen remodel here often uncovers the same infrastructure issues we see on ADU jobs: undersized panels, aging plumbing, and slab foundations that need careful planning before any cabinet comes out. Call (833) 620-3521 to talk through your kitchen, your budget, and what’s realistic on your lot.
Why Highland Homes Are Different
Highland’s housing stock runs heavily to mid-century single-family homes on lots that would be impossible to find in denser parts of the Inland Empire. That’s the good news: space for a detached ADU, room to expand a kitchen, and enough yard left over for a garden or a pool. The less visible reality is that many of these homes were built when 60-amp electrical service was standard, galvanized plumbing was common, and insulation was an afterthought. Summer days over 100°F punish every gap in a building envelope. Santa Ana winds find every loose roof edge.
Then there’s the septic and well situation. A meaningful share of Highland properties are not connected to municipal sewer. That changes what’s possible on any project that adds a bathroom, a kitchen, or a full ADU. San Bernardino County requires site-specific septic evaluations, and hillside lots frequently need geotechnical reports before foundations can be designed. In flatter cities nearby, a contractor might never mention a geotech report. In Highland, it’s often step one. Anyone quoting work without asking whether you’re on sewer or septic is not doing the homework.
Our Main Highland Services
Highland homeowners call us about two things more than anything else: adding an ADU to a generous lot, and bringing a tired bathroom up to modern standard. Both jobs share the same Highland-specific wrinkles: older panels, septic constraints, and a county permitting process that rewards preparation.
ADU Builders in Highland
Highland is one of the strongest ADU markets in the Inland Empire, thanks to lot sizes that routinely exceed 7,000 square feet and a planning department that processes accessory dwelling unit applications steadily. We build both prefab and site-built ADUs here, and we’ll walk you through the real tradeoffs: a Plant Prefab or Abodu unit can go from permit to occupancy faster, while a stick-built ADU gives you full control over layout and finish. Septic capacity is the biggest wildcard on many Highland lots, so we assess that before recommending any path. ADU Builders in Highland is where we cover that process in detail.
Bathroom Remodeling in Highland
Bathrooms in Highland’s mid-century homes were built compact: a 5-foot tub, a single vanity, and often a window that’s failed over 60 years of inland sun. We remodel these spaces to add storage, improve ventilation for hot summers, and bring plumbing up to current code. On septic-system properties, we coordinate fixture counts with the county’s requirements so a new soaking tub doesn’t overload the leach field. Whether the bathroom is inside your main house or part of a new ADU, it’s the same crew doing the work. Bathroom Remodeling in Highland covers the full scope.

Kitchen Remodeling in Highland
Kitchen remodeling in Highland usually means opening up a closed-off galley kitchen in a home built between 1955 and 1975, then rebuilding it to handle modern appliances, more counter space, and summer temperatures that push a poorly ventilated kitchen past uncomfortable. The specific problem we solve here is infrastructure: many of these homes still run on the original 60-amp or 100-amp panel, the original cast-iron drain lines, and slab floors that make moving plumbing a planning exercise, not an afterthought. By the time we’re done, the kitchen should work as hard as the rest of the house. Kitchen Remodeling is our main hub for this service, but here’s what Highland-specific work looks like.
Full Kitchen Renovation
Signs you need it
Your kitchen layout hasn’t changed since the Carter administration, cabinet doors no longer close square, and the stove is on a circuit that dims the lights when it cycles on.
What it costs in Highland
Full kitchen renovations in Highland typically run $35,000 – $55,000 depending on layout changes, cabinet grade, and whether the electrical panel needs upgrading.
How we do it
We start with a panel and plumbing assessment, map the new layout, pull county permits, then demolish, reframe, rough in electrical and plumbing, install cabinets and counters, and finish with flooring, backsplash, and appliances.
Cabinet Refacing and Countertop Replacement
Signs you need it
Your cabinet boxes are structurally fine but the doors are delaminating, the finish is worn through, and the countertops are chipped or stained beyond repair.
What it costs in Highland
Cabinet refacing and countertop replacement in Highland generally runs $8,000 – $18,000, with natural stone pushing toward the upper end of that range.
How we do it
We measure every box, order new doors and drawer fronts, strip and prep the existing frames, install new hardware, and template and cut new countertops for a one-week turnaround.
Island Addition with Seating
Signs you need it
You have a large kitchen with no island, no place for kids to do homework while dinner cooks, and unused floor space that could be working harder.
What it costs in Highland
Adding an island with seating in Highland typically falls between $6,000 and $14,000, which includes new electrical runs to the island location.
How we do it
We locate the island to preserve the work triangle, run a dedicated circuit under the slab or through the crawl space, then build and finish the island with matching cabinetry and a countertop overhang for seating.
What Kitchen Remodeling Costs in Highland
| Item | Typical range in Highland |
|---|---|
| Full kitchen renovation | $35,000 – $55,000 |
| Cabinet refacing + countertop replacement | $8,000 – $18,000 |
| Island addition with seating | $6,000 – $14,000 |
What pushes a Highland kitchen remodel toward the top of those ranges is usually hidden: an electrical panel that needs replacing before any new circuits can be added, cast-iron drain lines that have to be cut out, or a septic system that constrains where fixtures can go without a county sign-off.
How long does a kitchen remodel take in Highland?
Most Highland kitchen remodels take 4 to 8 weeks from demo to final walkthrough. Cabinet refacing can be done in about a week. Septic or hillside conditions may add county review time before work starts.
Will the price change once work starts?
Our quotes are line-item fixed prices. If we open a wall and find something genuinely dangerous or non-compliant, we’ll stop and show you exactly what we found before any change order. Call (833) 620-3521 for a free estimate.

Pricing for ADU Company in Highland, CA
| Service | Typical range in Highland |

| Cabinet refacing + countertop replacement | $8,000 – $18,000 |
| Island addition with seating | $6,000 – $14,000 |
In Highland, the biggest price swing comes from what’s underneath the work: electrical service that’s 50 years old, septic constraints that limit fixture placement, or hillside foundations that need a geotech report before anything gets built. Every quote we write is a fixed, line-item number, so the price you approve is the price you pay unless you change the scope.

FAQs About ADU Company in Highland

We’re an ADU specialist first. Our entire business is built around accessory dwelling units and the kitchens and bathrooms inside them. That’s not a side service; it’s what we do every day in Highland and across the Inland Empire.
It depends on scope and permitting. A cabinet refacing can start within a couple of weeks. A full ADU needs design, plan check, and county review, which typically runs 3 to 6 months before groundbreak. Call (833) 620-3521 and we’ll give you a realistic timeline for your specific property.
