ADU Company in San Antonio Heights, CA
Kitchen remodeling in San Antonio Heights usually means working inside a mid-century ranch or 1980s Mediterranean on a multi-acre parcel, where the existing layout was built for a different era of cooking and gathering. We’re Sapphire ADU Builders, and while ADU construction is our core, we deliver complete kitchen remodels as part of full ADU builds or as standalone projects – no second contractor needed for the interior finish. San Antonio Heights homes have real quirks: well water pressure, septic-conscious plumbing runs, and older framing that doesn’t always match modern cabinet dimensions. We’ve worked on enough kitchens here to know what’s behind those walls before we open them. Call (855) 594-0655 for a free kitchen remodeling estimate in San Antonio Heights.
Why San Antonio Heights Homes Are Different
San Antonio Heights is an unincorporated island of equestrian-zoned lots above the San Gabriel Valley, and that changes how every interior project works. Most homes in 91784 sit on well and septic, not city water and sewer. That means a kitchen remodel isn’t just swapping cabinets – it’s checking whether the new island sink drain ties into a septic line with enough fall, whether the well pump delivers the pressure a pot filler expects, and whether the county’s plumbing permit path applies rather than a city’s. The housing stock runs heavily to custom ranch and Mediterranean builds from the 1950s through the 1980s, with framing and subfloor conditions that vary house to house. We see original galvanized supply lines, undersized vent stacks, and load-bearing walls that a previous owner opened up without a permit. Elevation also matters. Hotter, drier summers and Santa Ana wind events make ventilation, range hood ducting, and window selection practical choices here, not style points. A kitchen that traps heat in August in San Antonio Heights is a kitchen you’ll hate by September.
Our Main San Antonio Heights Services
Two services generate most of our calls from San Antonio Heights homeowners: full ADU builds on those generous lots, and bathroom remodels that often get paired with a kitchen project. Here’s what each involves locally.
ADU Builders in San Antonio Heights
San Antonio Heights is one of the few places in the Inland Empire where an ADU usually means new ground-up construction or a barn conversion on a multi-acre parcel, not a garage makeover. Septic capacity and well setbacks drive the whole conversation – the county, not a city planning desk, reviews your leach field before any square footage gets approved. We match you to the right prefab or site-built ADU for your specific lot, and we’ve handled enough San Antonio Heights ADU permits to know which questions the county asks first.

Bathroom Remodeling in San Antonio Heights
Bathrooms in 1960s and 1970s San Antonio Heights ranches were built small, with cast iron plumbing that has outlived its useful life and tile set on mortar beds that slope in surprising directions. We gut and rebuild bathrooms as part of ADU interiors or as standalone remodels, handling the water pressure realities of well systems and the drainage constraints of septic lines. No second contractor for the finish work – one team owns the whole thing. Bathroom Remodeling in San Antonio Heights

Kitchen Remodeling in San Antonio Heights
Kitchen remodeling in San Antonio Heights costs roughly $28,000 to $75,000 depending on scope, and most projects here take 6 to 10 weeks once permits are issued. The biggest local variable is what we find when walls open up: 40-year-old plumbing, wiring that doesn’t meet current code, or a load-bearing situation a previous remodel ignored. We handle the full scope – cabinets, counters, appliances, plumbing, electrical, and flooring – so you’re not coordinating a general contractor, a plumber, and an electrician yourself. Our Kitchen Remodeling process starts with a fixed, line-item quote before any work begins.
Full kitchen gut and rebuild
Signs you need it
Your San Antonio Heights kitchen has original 1960s-1980s cabinets, a layout that isolates the cook from everyone else, and flooring that predates your appliances.
What it costs in San Antonio Heights
A full kitchen gut and rebuild in San Antonio Heights typically runs $38,000 to $75,000 depending on cabinet grade, countertop material, and how much electrical and plumbing gets reworked.
How we do it
We demo to the studs, address any framing or subfloor issues, run new plumbing and electrical, then rebuild with new drywall, cabinetry, counters, flooring, and appliances.
Cabinet replacement and countertop upgrade
Signs you need it
Your cabinet boxes are still structurally sound but the doors are delaminating, hinges are failing, and your counters are chipped laminate or dated tile.
What it costs in San Antonio Heights
Cabinet replacement and countertop upgrades in San Antonio Heights typically run $15,000 to $30,000 depending on whether we’re refacing, replacing, and what surface you choose.
How we do it
We measure, order, remove existing cabinets and counters, install new boxes or refaced doors, fit the countertops, and reconnect the sink and fixtures.
Island and layout reconfiguration
Signs you need it
Your current kitchen has dead corners, a peninsula that blocks traffic, or no island at all and you want a functional cooking triangle.
What it costs in San Antonio Heights
Layout changes with an island in San Antonio Heights run $18,000 to $40,000 because they almost always involve moving plumbing, electrical, and sometimes opening a load-bearing wall.
How we do it
We assess the framing, plan the new traffic flow, move the rough plumbing and electrical, build the island, and install the surfaces and fixtures around it.

Will my kitchen remodel hold up to San Antonio Heights heat and wind?
