Fast, Reliable General Contractor Across San Antonio Heights
Finding a General Contractor who understands the unincorporated side of San Bernardino County is not as simple as picking the first name on a search. San Antonio Heights runs on county permits, slope reviews, and wildfire code, not a city hall counter. Stallion Contractors has worked through that process enough times to know where the plan-check snags happen and how to avoid them. If you’re planning a kitchen remodel, a full home addition, or an ADU on a foothill lot in 91784, call us at (855) 600-3192 and we’ll tell you exactly what your project needs before the first inspection.
Why Stallion Contractors Is San Antonio Heights’s Preferred General Contractor Company
We’ve pulled permits through County of San Bernardino for projects across San Antonio Heights, and that experience matters. A homeowner near Euclid Avenue who needs an addition on a sloped parcel requires different engineering than a flat-lot remodel in Upland. Our team has handled both. We know what triggers a geotechnical review and what doesn’t, and we build that step into the schedule from day one so you’re not surprised by a plan-check hold three weeks in.
San Antonio Heights homeowners call us because we carry full-scope capability under one contract. You don’t manage a separate roofer, a separate window company, and a separate hardscape crew. We run the whole job, from footings to fascia. Our customers here tell us the same thing: the single point of accountability is what keeps a hillside remodel from turning into a blame game between trades. Ruben Montoya leads every project with that expectation set from the start.
Our response time to San Antonio Heights is same-week for estimates and often sooner. We schedule detailed site walks so we can see the slope, the soil, and the access path before we put a number in front of you. That’s the difference between a quote that holds and one that falls apart at the first inspector visit.
Styles & brands we work with
Construction Company in San Antonio Heights
A construction company in San Antonio Heights does more than frame walls and hang drywall. Here, the work starts with county permitting, geotechnical review for sloped parcels, and wildfire-mitigation compliance baked into the plans. Homeowners call us when they want a home addition that won’t stall in plan check because the civil drawings didn’t include drainage. They call us when an aging mid-century ranch needs structural upgrades before new finishes go in. A typical home addition in San Antonio Heights runs $45,000 – $130,000, driven largely by foundation work on hillside lots and the engineering reports that go with it.
County Permitting and Slope Work
Building in an unincorporated area means the County of San Bernardino reviews every structural detail. Sloped parcels along the foothills often require a geotechnical letter before footings can be approved. We bring the geotech in early so the foundation design matches the soils report, not the other way around. That sequencing saves weeks.
Structural Upgrades for Older Homes
Many San Antonio Heights homes are mid-century ranch builds, and a good number of them have beams and foundations that were never designed for today’s loads. Before we remodel a kitchen or add square footage, we check what’s underneath. Replacing a failing beam as part of the scope is common here, especially on hillside lots where movement has been happening for decades.
Remodeling Contractor in San Antonio Heights
A remodeling contractor in San Antonio Heights has to think beyond tile selection and cabinet layouts. Wildfire code affects exterior assemblies, roof vents, decking, and even window choices on remodel projects here. Homeowners call us when they want a kitchen remodel that triggers a roof or vent upgrade and they need one contractor who can handle both without subbing out the critical parts. A kitchen remodel in San Antonio Heights typically runs $14,000 – $45,000, and a bathroom remodel runs $9,000 – $28,000, depending on structural work and the materials you choose from our brand partners.
Interior Remodels with Exterior Consequences
A kitchen remodel that opens up a wall can change a home’s lateral load path. That’s a county review item in a fire-hazard zone. Our Remodeling Contractor team plans for those triggers so the scope includes any required shear wall or vent upgrade from the start, not as a change order after tear-out.
Bathroom and Kitchen Work
We handle full bathroom and kitchen scopes with professional-grade materials: Cambria, Silestone, and Caesarstone countertops; KraftMaid and Wellborn cabinetry; Kohler and Toto fixtures. Our brand partnerships mean we recommend materials matched to the actual demands of your San Antonio Heights home, not whatever is on display at a showroom.
Trusted Brands We Service in San Antonio Heights
Our material partnerships matter more in San Antonio Heights than in most places. Class A roofing from GAF, CertainTeed, or Owens Corning is a wildfire-code requirement on many remodels here, not an upsell. James Hardie siding and ember-resistant vent assemblies need to meet county review standards. We also work with prefab and ADU partners including Abodu, Dvele, and Cover, which gives San Antonio Heights homeowners access to factory-built accessory units that often clear county plan check faster than stick-built designs. Pro-grade materials, professionally installed.

AfterCommon General Contractor Problems We See in San Antonio Heights Homes
- Plans submitted without a geotechnical report. On sloped parcels, county plan check will not move forward without soils and drainage review. We see homeowners lose four to six weeks when a cheap quote skipped this step.
- Standard roof vents instead of ember-resistant assemblies. San Antonio Heights sits in a high fire-hazard severity zone on the wildland-urban interface. Standard vents fail wildfire code review and can put your insurance renewal at risk.
- Retaining wall failures on older hillside lots. Many of these walls were built forty or fifty years ago without engineered drainage. When a remodel increases the load above them, they need to be brought up to current county standards.
- Change-order disputes on structural and wildfire upgrades. When wildfire-mitigation work is not written into the original scope and contract, the homeowner is exposed. We put every required upgrade in writing before the first draw.

FAQs About General Contractor in San Antonio Heights
San Antonio Heights sits in a high fire-hazard severity zone on the wildland-urban interface, so the county requires ember-resistant vents and Class A roof assemblies on remodels that touch the roof or exterior envelope. A compliant quote includes those items explicitly. Call (855) 600-3192 to review your specific scope.
Because San Antonio Heights is in unincorporated San Bernardino County on sloped foothill terrain, the county requires a geotechnical report for most additions, ADUs, and structural remodels on hillside parcels. The report confirms soil stability and drainage before footings are approved. We bring the geotech in early so your plan check does not stall.
The fix is a written contract that includes every structural and wildfire-mitigation upgrade the county will require, priced before work starts. We document the geotech letter, the ember-resistant assemblies, the retaining wall repairs, and the drainage plan in the original scope. Call (855) 600-3192 for a written quote that does exactly that.
Yes. Documented Class A roof assemblies, ember-resistant vents, and defensible-space compliance give your insurer hard evidence your home meets current wildfire code. That can directly affect renewal terms in a high fire-hazard zone like San Antonio Heights. We provide documentation after every inspection sign-off.
A compliant quote for San Antonio Heights includes the geotechnical report for slope work, ember-resistant vents, Class A roofing materials, defensible-space plan updates, and county inspection fees. A cheap quote leaves those out and hits you with change orders after tear-out. Call (855) 600-3192 and we’ll line-item the difference for your project.
On a hillside remodel off Ridge Line Drive, our crew replaced a failing load-bearing beam in a mid-century ranch, then added ember-resistant vents and a Class A roof assembly to satisfy the county’s high fire-hazard review. The inspection sign-off came only after we provided a geotech letter for the new footing and a defensible-space plan. That’s the standard we build to here.
From the kitchen to the roofline, one contractor handles every trade. Your project managed start to finish, built to the standard your home deserves. Call (855) 600-3192 to schedule your free estimate in San Antonio Heights.
