ADU Company in Highland, CA
Kitchen remodeling in Highland usually means working inside a 1950s or 1960s ranch home where the original layout, wiring, and plumbing are still doing the job they were built for, long past when they should have retired. We’re Newport Beach ADU Builders, and we’ve served Highland since 2016. That matters because Highland kitchens come with specific problems: older electrical panels that can’t support modern appliance loads, cast-iron drain lines that have corroded under decades of hard water, and wall layouts that predate the way families actually cook now. Call (844) 934-0236 and we’ll tell you honestly what your kitchen needs and what it doesn’t.
Why Highland Homes Are Different
Highland’s housing stock runs heavily to single-story ranch homes built between the 1950s and 1970s, most of them on larger lots than you’ll find in San Bernardino or Redlands. That’s good news for anyone adding an ADU or remodeling a kitchen: there’s room to work. But those same homes come with original electrical panels, often 100-amp or less, that were sized for an era of incandescent bulbs and a single window air conditioner. Adding a second dwelling or a modern kitchen with double ovens, induction cooktops, and dedicated circuits means a panel upgrade, and sometimes a service line upgrade from the pole. Older septic systems on some Highland properties add another layer: a second dwelling may require a septic system evaluation and possible upsizing before the city will sign off. Highland sits in a CAL FIRE wildfire hazard zone, so any construction that touches roofing, vents, or exterior walls has to meet ember-resistant standards that don’t apply in neighboring flatland cities. The city has also signaled a legitimate interest in converting unpermitted outbuildings into legal ADUs, which means homeowners with a converted garage or shed that was never permitted may have a path to bring it into compliance rather than tear it down. Every one of these factors changes the scope, the timeline, and the budget.
Our Main Highland Services
Highland homeowners call us most often about two projects: building new ADUs and remodeling bathrooms in older ranch homes. Both involve the same local realities: aging infrastructure, wildfire-zone code requirements, and the need to pull permits through the City of Highland without surprises.
ADU Builders in Highland
Building an ADU in Highland starts with questions most single-brand dealers won’t ask: Is your lot on septic or sewer? What’s your current electrical service? Is there an existing outbuilding the city considers legal nonconforming? We work across multiple manufacturers, so we can match the build method to your lot, your budget, and your schedule rather than selling you whatever one factory happens to produce. Highland’s wildfire-zone requirements affect exterior materials, vent types, and roofing choices, and we handle that as part of the permit package. For full details on the process in Highland, see ADU Builders in Highland.
Bathroom Remodeling in Highland
Highland’s 1950s and 1960s bathrooms often hide problems behind the tile: galvanized supply lines that have narrowed to a fraction of their original diameter, original cast-iron drain stacks, and subfloor rot from decades of slow leaks around tub surrounds. A bathroom remodel here is rarely cosmetic once the walls come open. We plan for what we’ll find, not just what we can see, and we quote accordingly. Bathroom Remodeling in Highland covers the specific scope of work, timeline, and local permit path for these projects.

Kitchen Remodeling in Highland
Kitchen remodeling in Highland is as much about bringing the home’s infrastructure current as it is about cabinets and countertops. The average 1960s ranch kitchen in 92346 was built with a 40-amp stove circuit, two countertop outlets, and no exhaust ventilation to the outside, and none of that meets today’s code or today’s cooking habits. Our Kitchen Remodeling work here typically includes panel and wiring upgrades, appliance circuit additions, proper range hood venting, and correcting original drainage and supply lines before the finish materials ever go in. Highland’s hot inland summers also make a real case for adding air conditioning vents or a mini-split in a remodeled kitchen, because a room with a 12,000-BTU range and no cooling is unusable for a third of the year.
Panel and electrical upgrades
Signs you need it
Your breakers trip when the microwave and toaster run at the same time, your panel is full, or it’s a Federal Pacific or Zinsco brand that insurers flag for replacement.
What it costs in Highland
Upgrading from a 100-amp panel to a 200-amp panel in a Highland ranch home typically runs $2,800 to $4,500, with the higher end applying when the service mast or meter base also has to move.
How we do it
We verify the existing service size, file the electrical permit through the City of Highland, coordinate with Southern California Edison for the disconnect/reconnect, install the new panel, and run dedicated circuits for the planned kitchen appliances.
Full kitchen replacement
Signs you need it
Cabinet face frames are separating, drawers no longer close square, the layout blocks the stove from the sink from the refrigerator, or you’re past the point where refacing would ever be worth the money.
What it costs in Highland
Full kitchen replacement in a Highland ranch, with mid-range cabinetry, quartz countertops, tile backsplash, and new plumbing fixtures, runs $22,000 to $45,000 depending on square footage and appliance selection.
How we do it
We demo to the studs, rough in electrical and plumbing to the new layout, patch and level the wallboard, install cabinetry and counters, then trim out with fixtures and finishes.

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."
— 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."
— Malik Nash
