ADU Company in San Antonio Heights, CA
Kitchen remodeling in San Antonio Heights means working with mid-century ranch homes on oversized lots, where outdated layouts and original cabinetry are common but the room to expand usually isn’t a problem. Holloway ADU Builders has served San Antonio Heights since 2016, handling kitchen remodels in these custom homes while navigating County of San Bernardino permitting rather than City of Upland rules. If you’re weighing a kitchen update alongside an ADU project, one team can handle both. Call (855) 617-6356 to talk through your options.
Why San Antonio Heights Homes Are Different
San Antonio Heights is an unincorporated San Bernardino County island completely surrounded by the City of Upland. That jurisdictional quirk means every kitchen remodel, bathroom update, and ADU addition here answers to County building and planning rules, not Upland’s. Homeowners who assume Upland codes apply often find their plans stalled during plan review. Contractors based outside the area make the same mistake, then scramble when County fire-safe construction standards and drainage requirements come back as corrections.
The housing stock itself sets San Antonio Heights apart from neighboring cities. Lots are large and estate-like, with custom and mid-century ranch homes set back on big parcels. Many properties have detached garages, workshops, and outbuildings that simply don’t exist on the tighter lots down in Upland or Claremont. For remodeling, that means we’re often working inside homes with original 1950s and 1960s framing, wiring that predates modern kitchen loads, and floor plans that were never designed for open-concept living. The homes have character worth preserving, and the room to build almost anything a homeowner wants.
Our Main San Antonio Heights Services
Two projects dominate the phone calls we get from San Antonio Heights homeowners: building an ADU on one of the area’s large lots, and remodeling bathrooms in mid-century homes that haven’t been touched in decades. Here’s how each one works locally.
ADU Builders in San Antonio Heights
San Antonio Heights is one of the best ADU sites in the Inland Empire because the lots are big and setbacks rarely constrain a detached unit. The catch is the County process: fire-safe roof and eave assemblies matter here because the neighborhood sits in wildland-urban interface territory at the base of the San Gabriel Mountains. We help homeowners sort through prefab, modular, site-built, and Tuff Shed conversion options without pushing one brand.

Bathroom Remodeling in San Antonio Heights
Many San Antonio Heights bathrooms are original to the home, with cast-iron plumbing, small footprints, and layouts that made sense in 1962 but don’t now. Because these are custom homes rather than tract builds, there’s no standard bathroom template, so each remodel requires actual design work. We handle the full bathroom scope alongside any ADU interior finishing. For the complete picture, see Bathroom Remodeling in San Antonio Heights.

Kitchen Remodeling in San Antonio Heights
Kitchen remodeling in San Antonio Heights is our most requested service. The typical project involves a mid-century ranch or custom home built between 1950 and 1980, an original kitchen with worn cabinets and insufficient counter space, and a homeowner who wants a functional cooking space without erasing the home’s character. Because these houses sit on large parcels, we can expand into adjacent square footage, bump out a wall, or reconfigure the layout without the lot-size handcuffs that constrain remodels down in Upland. Strong Santa Ana winds and hot inland summers also shape decisions here: ventilation, window placement, and heat-generating appliance choices all respond to a climate where air conditioning runs hard from June through October. If you’re also planning an ADU with a kitchen, we can coordinate both. See how our scope fits at Kitchen Remodeling.
Full Kitchen Renovation
Signs you need it
Your kitchen has the original 1960s cabinets, the layout isolates the cook from everyone else, or you’re planning to sell and the kitchen is the one room holding back the listing price in San Antonio Heights.
What it costs in San Antonio Heights
A full kitchen renovation in San Antonio Heights runs $45,000 to $90,000 depending on footprint changes, cabinet grade, and whether walls move.
How we do it
We start with as-built measurements and a County permit check, then move through demo, framing changes, rough plumbing and electrical, drywall, cabinet and countertop install, and finish work, keeping the project sequenced so you’re not living in construction longer than needed.
Kitchen Cabinet Replacement
Signs you need it
Your existing cabinets are structurally fine but the doors are delaminating or yellowed, the hinges are failing, or you want a different layout without gutting the entire room.
What it costs in San Antonio Heights
Cabinet replacement in San Antonio Heights typically costs $12,000 to $30,000 for semi-custom or stock cabinets across a standard kitchen footprint.
How we do it
We remove existing boxes and hardware, verify the wall framing can carry the new load, and install new cabinets with level bases and soft-close hardware before the countertop template is cut.
Countertop and Backsplash Replacement
Signs you need it
Your existing laminate or tile counters are chipped, stained, heat-damaged, or simply dated, and the kitchen otherwise functions well enough to leave the layout alone.
What it costs in San Antonio Heights
Countertop and backsplash replacement in San Antonio Heights typically ranges from $6,000 to $14,000 depending on surface material and square footage.
How we do it
We remove the old surface without damaging the cabinet bases, template the new countertop on site, then fabricate and install the material with a matching or coordinating backsplash and sealed seams.

How long does a kitchen remodel take in San Antonio Heights?
A full renovation here runs 8 to 14 weeks from demo to final walkthrough, with County inspections adding one to three weeks depending on review volume. Cabinet-only or countertop-only jobs finish in 2 to 4 weeks. Call (855) 617-6356 for a realistic timeline for your scope.
Will County permitting slow down my kitchen remodel?
Yes, plan review and inspections typically add time compared to a city-run process, but the requirements aren’t a mystery to us. We prepare submittals to match County expectations the first time, which keeps corrections to a minimum. Call (855) 617-6356 and we’ll walk you through the timeline.
