ADU Company in San Antonio Heights, CA
Kitchen remodeling in San Antonio Heights follows a different playbook than the tract homes down the hill in Upland or Rancho Cucamonga. The housing stock here skews mid-century and custom, which means wide lot lines, angled rooflines, and layouts that were framed before open-concept was even a phrase. Add foothill heat, Santa Ana wind exposure, and San Bernardino County permitting, and you need a contractor who understands this specific terrain. Camden ADU Builders has served San Antonio Heights since 2017, and our kitchen work runs from cabinet replacement to full gut remodels, always tied to what your house actually needs. Call (844) 747-5499 when you’re ready to talk through your project.
Why San Antonio Heights Homes Are Different
San Antonio Heights is an unincorporated San Bernardino County island perched in the foothills above Upland and Rancho Cucamonga. That single fact changes nearly every part of a kitchen remodel. The homes here were largely built as custom and semi-custom projects from the 1950s through the 1980s, sitting on acre-plus lots with generous setbacks and floor plans that don’t follow a single developer’s template. You’ll see split-levels, ranch ramblers, and the occasional contemporary that climbs the slope, all of which means kitchen layouts vary wildly from house to house. What works as a standard U-shaped galley in a 1970s rancher won’t translate to a mid-century split-level with exposed beams.
The elevation also matters more than people expect. San Antonio Heights sits high enough that summer afternoons run noticeably hotter than the valley floor, and Santa Ana winds push through with real force in the fall. Kitchens here accumulate heat fast, especially west-facing ones with original single-pane windows. Remodels in this community routinely include better ventilation, higher-capacity HVAC runs, and window upgrades that would be optional in Claremont or Montclair. And because this is wildland-interface terrain, any structural change triggers fire-safety requirements under County Plan Check, from ignition-resistant materials to clearance rules around the home’s exterior. We plan for those constraints from the first conversation.
Our Main San Antonio Heights Services
San Antonio Heights homeowners call us most often about two projects: adding an ADU to a large foothill lot, and remodeling bathrooms in homes that haven’t been touched since the original build. Here’s what each involves in this community.
ADU Builders in San Antonio Heights
Detached ADUs are the dominant conversation in San Antonio Heights because the lots are actually big enough to support them. Many properties have existing detached garages, shops, or outbuildings that can be converted or replaced, which opens options that tract neighborhoods simply don’t have. The catch is County jurisdiction: San Antonio Heights projects go through San Bernardino County Plan Check, not a city building department, and the WUI (Wildland-Urban Interface) overlay adds fire-hardening requirements that shape materials, setbacks, and even where the ADU can sit on the lot. We coordinate that entire process, from manufacturer selection through permitted construction. ADU Builders in San Antonio Heights
Bathroom Remodeling in San Antonio Heights
Bathrooms in San Antonio Heights tend to be original to the home, which means cast-iron tubs, dated tile, and layouts that don’t handle foothill summer humidity well. We frequently open up compartmentalized bathrooms from the 1960s and 1970s into more usable footprints, addressing ventilation and water-damage issues common in older foothill construction. But any bathroom that shares a wall with an exterior surface or involves plumbing under a slab faces stricter County inspection and possible WUI exterior requirements. We handle the full scope, from permits to tile and fixtures, in-house. Bathroom Remodeling in San Antonio Heights

Kitchen Remodeling in San Antonio Heights
Kitchen remodeling in San Antonio Heights is rarely a cosmetic refresh. The homes were built between the 1950s and 1980s, and most kitchens are still running original cabinets, dated electrical, and layouts that fight against how people actually cook now. Foothill heat makes ventilation and window performance a functional issue, not an aesthetic one. We approach every kitchen here as a full-scope project: layout, cabinetry, countertops, ventilation, lighting, and flooring, with County Plan Check and any WUI exterior implications handled from the start. Whether you’re comparing prefab versus custom approaches anywhere in the house, our Kitchen Remodeling team delivers the same level of option transparency for interiors.
Cabinet Replacement
Signs you need it
Drawer faces are delaminating, hinges sag, and the existing cabinet boxes are particleboard that’s absorbed decades of foothill dry heat and now crumble at the screw points.
What it costs in San Antonio Heights
Cabinet replacement in San Antonio Heights typically runs $9,500 to $22,000 depending on the cabinet grade, count of boxes, and whether you’re staying with stock sizes or going semi-custom to fit mid-century dimensions.
How we do it
We pull the old boxes, check and reframe any walls that never had proper blocking, then install new cabinets with leveling that accounts for the slab settling common in older foothill foundations.
Countertop Installation
Signs you need it
Original laminate or tile counters have burn marks, cracked grout, or seams that have lifted from years of high-heat cooking and dry-air exposure.
What it costs in San Antonio Heights
Countertop replacement here typically falls between $3,000 and $8,500 for quartz or quartzite, with the higher end reflecting larger mid-century kitchens and custom edge profiles.
How we do it
We template after cabinets are set, fabricate off-site to keep dust out of your home, then install with a full-height backsplash if you want to eliminate grout lines entirely.

Prices climb in San Antonio Heights when walls move, when slab plumbing needs relocation on an older foundation, or when WUI requirements demand upgraded exterior penetrations around a new range hood vent. We write fixed line-item quotes before work starts, so the number you approve is the number you pay, no change orders mid-job.
How long does a kitchen remodel take in San Antonio Heights?
Most full kitchen remodels in San Antonio Heights run 6 to 10 weeks, with cabinet replacement alone typically 2 to 3 weeks. County Plan Check can add 2 to 4 weeks at the front end depending on current review volume.
Do I need permits for a kitchen remodel in San Antonio Heights?
Yes. As an unincorporated San Bernardino County community, any kitchen work that touches electrical, plumbing, or structural walls requires County permits and inspections. We pull permits, schedule inspections, and close everything out before final walkthrough.
Brands We Service in San Antonio Heights
Camden ADU Builders works hands-on with six prefab ADU manufacturers: Abodu, Cover, Dvele, Mighty Buildings, Boxabl, and Plant Prefab. For San Antonio Heights specifically, we most often compare Dvele and Mighty Buildings for premium foothill-ready units, and Boxabl or Plant Prefab when the goal is a tighter budget or faster County approval. Because we aren’t tied to one manufacturer, we recommend based on your lot, your slope, and your WUI obligations, not a dealer margin. See our brands for the full line and what each manufacturer does best.
