ADU Company in Highland, CA
Adding an ADU in Highland, CA means working with a city where large-lot 1950s – 1980s parcels, foothill-adjacent terrain, and strict wildfire-safety codes all shape the project from the first site visit. Casita ADU Builders handles ADU construction plus the kitchen and bathroom remodeling that finish the interior under one contract, so you’re not hiring a second contractor to complete the space. Call (877) 658-7475 to schedule a free estimate on your Highland property.
Why Highland Homes Are Different
Highland’s housing stock runs from mid-century single-story stucco tract homes to newer east-side subdivisions, and most parcels are generous enough that a detached ADU doesn’t feel like a squeeze. Block-wall rear yards, detached garages, and undeveloped back-lot space are common here, which makes standalone casitas and garage conversions both realistic. But the older parcels carry quirks: aging block walls, flat or low-pitch rear patios, and sewer and water laterals that predate any idea of a second dwelling. Extending those utility runs is often the first real cost surprise on a Highland ADU project.
Highland sits at the base of the San Bernardino foothills, and the northern edges of the city carry elevated wildfire exposure. That means Class A roofing, ember-resistant vents, and defensible-space setbacks show up on more Highland ADU plans than you’d see in Redlands or San Bernardino. Summers run hot, with 100°F-plus stretches that make efficient HVAC and solar part of the conversation early. And the region’s hard, mineral-heavy water means plumbing for a new ADU should plan for softening or treatment from day one, not as a retrofit after the first six months of scale buildup.
Our Main Highland Services
Two services come up most when Highland homeowners call us: full ADU construction and bathroom remodeling that brings the interior up to the same standard as the rest of the house. Each has its own Highland-specific page, but here’s the short version of what each job involves here.
ADU Builders in Highland
Highland’s ADU activity centers on siting a standalone casita on a half-lot with room to spare, not cramming a JADU into a garage. Foothill-adjacent parcels often trigger defensible-space and fire-access review, and SB 9 lot splits are a recurring conversation on larger parcels. We match the build type to your lot, budget, and timeline, and we handle the full interior finish through our in-house remodeling team. ADU Builders in Highland covers the full scope of what we do here.
Bathroom Remodeling in Highland
Many Highland ADU projects start with a bathroom that’s dated, cramped, or poorly laid out against a block wall that limits window and venting options. The hard water in this region also takes a toll on fixtures and valves faster than homeowners expect. We plan bathroom remodels around Highland’s specific plumbing realities, including water softening, venting against older stucco walls, and layouts that work within existing slab and footing constraints. Bathroom Remodeling in Highland explains the full process.

Kitchen Remodeling in Highland
Kitchen remodeling in Highland typically runs $18,000 – $75,000 depending on whether you’re refreshing a mid-century galley layout or reconfiguring a larger open-plan space in a newer east-side home. Highland’s older stucco tract kitchens often have load-bearing walls that complicate any thought of opening the room up, and the mineral-heavy water here means fixture and faucet choices need more thought than they would in a softer-water city. We work with these conditions daily, and our team prepares every Highland kitchen plan around the specific plumbing, venting, and structural realities of your house’s era. If you’re weighing a kitchen remodel alongside an ADU project, our Kitchen Remodeling team handles the full interior scope under the same contract.
Full Kitchen Renovation
Signs you need it
A Highland kitchen with original mid-century cabinetry, a single wall of counter space, and no ventilation to the outside is working against how your family actually lives.
What it costs in Highland
A full kitchen renovation in Highland generally runs $35,000 – $75,000, with the upper range common when load-bearing walls come out or plumbing gets relocated.
How we do it
We pull permits, handle the structural work, reroute plumbing and electrical, then install cabinetry, countertops, ventilation, and fixtures to a finished room.
Cabinet Refacing and Countertops
Signs you need it
If your cabinet boxes are solid but the faces, hinges, and counters look worn, refacing gives you a new kitchen without tearing out everything.
What it costs in Highland
Cabinet refacing with new countertops in Highland typically runs $8,000 – $18,000, depending on linear feet and stone selection.
How we do it
We replace doors, drawer fronts, and hardware, then template and install new countertops with a fit matched to your existing cabinet layout.

How long does a kitchen remodel take in Highland?
A full Highland kitchen remodel usually runs 6 – 10 weeks from demolition to final walkthrough, with permits adding about two weeks at the front end. Refacing jobs run faster, often 2 – 3 weeks. Call (877) 658-7475 for a timeline specific to your project.
Do I need water softening in my Highland kitchen remodel?
Highland’s mineral-heavy water means new kitchen fixtures and faucets last noticeably longer when the supply runs through a softener or treatment system. We plan for this at rough-in, not after the countertops go in.

What Highland 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."
— Arjun Singh"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Robert Gallagher"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."
— Aisha Prince
