ADU Company in Highland, CA

Kitchen remodeling in Highland means working with homes built mostly between the 1960s and 1990s, where original cabinetry has outlived its usefulness and floor plans weren’t designed for how families cook now. We see a lot of galley kitchens and closed-off layouts in the ranch and tract homes across 92346 that need to open up without compromising the structure’s mid-century bones. Highland’s hot, dry summers also shape material choices: solid wood doors that would warp in humidity do fine here, but laminate countertops from the 1980s have usually faded and chipped past saving. Call Cottage ADU Builders at (866) 808-7312 and we’ll walk the space with you before you commit to anything.

Why Highland Homes Are Different

Highland sits in the Inland Empire’s foothill zone, and that changes how we approach every project here. Lots are typically larger than in San Bernardino or Redlands, and many slope toward the San Bernardino Mountains, which means grading and drainage aren’t afterthoughts, they’re often the first conversation. A kitchen remodel in a flat-lot tract home is a different job than one in a hillside ranch where the original slab has settled and the floor isn’t level anymore.

The housing stock is the other big factor. Highland has a high share of owner-occupied single-family homes from the mid-century era through the 1990s. Many still have their original kitchens. That means we’re frequently removing load-bearing walls between kitchen and living room, relocating plumbing that was roughed in for a different appliance layout, and dealing with electrical panels that predate modern code requirements for dedicated appliance circuits.

Santa Ana winds matter too. When we open up an exterior wall for a range hood, a window, or a pass-through, the sheathing and flashing need to be done right the first time. Wind-driven rain in the winter months will find any gap. Highland’s occasional heavy rain events, paired with sloped lots, also mean we pay close attention to how any exterior kitchen work ties into the surrounding roofline and gutter system.

Our Main Highland Services

Highland homeowners call us most often about two things: adding a detached or converted ADU on their larger lot, and refreshing a bathroom in a home that hasn’t seen an update in thirty or forty years. Both jobs benefit from a contractor who already knows the local stock.

ADU Builders in Highland

Highland’s larger, often sloped lots make detached ADUs a realistic option where a city like Redlands or Loma Linda might push you toward a garage conversion. We handle the full scope, from grading and drainage design to the finished unit, and we work fluently with prefab and modular systems like Abodu, Cover, and Plant Prefab when a factory build suits your timeline better than stick-frame. See ADU Builders in Highland for the full breakdown.

Bathroom Remodeling in Highland

Most Highland bathrooms we see are original to 1970s and 1980s tract construction: small footprints, single vanity, fiberglass tub-shower combo, and a fan that vents into the attic rather than outside. We correct the ventilation, open the layout where the floor plan allows, and bring the finishes up to something that lasts under Highland’s hard water. Read more at Bathroom Remodeling in Highland.

Kitchen Remodeling in Highland

A kitchen remodel in Highland starts with an honest look at the home’s era. Most of the kitchens we work on in 92346 were built between 1965 and 1995, which means one of two things: either the original layout is still there and needs a full gut, or a previous owner did a surface-level refresh in the early 2000s and the cabinets are starting to fail at the hinges and drawer slides. Highland’s dry heat and hard water accelerate wear on faucets, disposals, and any laminate surface, so material selection matters more here than in coastal cities. We offer full Kitchen Remodeling services, from demolition through finished trim, and we’ll help you sort out what’s worth saving in an older Highland home before you spend money replacing it.

Cabinet Replacement and Refacing

Signs you need it

Drawers stick, doors won’t close square, or the boxes themselves have water damage around the sink base, common in Highland homes with original 1980s particleboard cabinets.

What it costs in Highland

Cabinet refacing in Highland typically runs $7,000 to $15,000, while full custom cabinet replacement lands between $20,000 and $45,000 depending on layout and materials.

How we do it

We measure the full run, check for square and level (critical in older Highland homes where slabs have settled), remove boxes or skins accordingly, and install new doors, hardware, and drawer systems on a properly reinforced base.

Countertop and Backsplash Replacement

Signs you need it

Laminate edges are peeling, grout lines in the backsplash are cracking, or the current counters are cut for a cooktop that’s long gone.

What it costs in Highland

Countertop and backsplash replacement in Highland typically ranges from $4,500 to $11,000, with quartz and solid-surface options at the upper end of that.

How we do it

We template the existing cabinets after leveling, fabricate the slab off-site, and install with a focus on the seam placement and overhang details that fail first in Highland’s dry, expanding/clay soil conditions.

What Kitchen Remodeling Costs in Highland

Item Typical range in Highland
Cabinet refacing $7,000 – $15,000
Full cabinet replacement $20,000 – $45,000
Countertop and backsplash replacement $4,500 – $11,000

Can you remodel a Highland kitchen without moving the plumbing?

Usually yes, if the sink and dishwasher are staying on the same wall and the slab is in good shape. Moving plumbing in a Highland slab foundation adds cost and time, but it opens up the layout. Call (866) 808-7312 for a site visit.

Do Highland kitchen remodels require permits?

Yes, anything touching electrical, plumbing, or load-bearing walls needs a city permit, and Highland enforces that. We pull permits and schedule inspections as part of the job, so you’re not left guessing at the end.

Brands We Service in Highland

We work regularly with Boxabl, Plant Prefab, Tuff Shed, and James Hardie on Highland projects, and our crew knows the delivery and install requirements for each system. Materials are sourced through our supply network, so Highland jobs don’t wait on the same backorders that stall big-box remodels. See our brands for the full list.

What Highland Customers Say

★★★★★ 4.8 from 4+ reviews

"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."

— Shane Miller

"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."

— Amanda Walsh

"The kitchenette layout he suggested made better use of the space than the one on our original sketch."

— Lucia Flores
