Fast, Reliable General Contractor Across Highgrove
Hiring a General Contractor in Highgrove means dealing with something most homeowners don’t expect: Riverside County building rules, not city ones. That changes how permits get pulled, how septic and well work gets approved, and how long your project takes. We know the county process because we work it constantly. If you’re planning a kitchen remodel, home addition, or detached ADU on your Highgrove property, call Ruben Montoya and the Stallion Contractors team at (855) 600-3192. We’ll walk your specific lot through the county requirements before you spend a dollar.
Why Stallion Contractors Is Highgrove’s Preferred General Contractor Company
Highgrove sits in unincorporated Riverside County, which means every permit runs through the county’s Building & Safety office in Riverside, not a city hall counter. A lot of contractors who work San Bernardino or Riverside don’t realize that until they’re three weeks into a job. We do. We’ve pulled permits for projects off Center Street, worked around septic setbacks on citrus-era lots, and dealt with county Environmental Health sign-off on well tie-ins. That’s the stuff that separates a smooth Highgrove project from one that stalls at inspection.
Ruben Montoya built this company around one contract and one accountable team. From the kitchen to the roofline, one contractor covers every trade. Homeowners in Highgrove don’t need to chase down a framing crew, a plumber who understands county code, and a roofer who’ll actually show up. We manage it start to finish, with pro-grade materials from manufacturers like Cambria, GAF, and James Hardie.
Our Highgrove customers tell us the same thing: the county process felt overwhelming until someone who actually knew it took over. That’s the job. Call (855) 600-3192 and we’ll scope your project against the actual Highgrove conditions: your lot, your well, your septic, your drainage.
Styles & brands we work with
Remodeling Contractor in Highgrove
A Remodeling Contractor in Highgrove handles interior and exterior renovations ranging from kitchen and bath overhauls to whole-home reconfigurations. Highgrove’s housing stock leans mid-century single-family homes on large rural lots, many with private wells and septic systems. That means a remodel here frequently involves more than cabinets and tile: you may be tying new plumbing into a well line, upgrading electrical on a 1960s panel, or reinforcing floor framing that’s seen fifty years of Inland Empire heat. A kitchen remodel in Highgrove typically runs $14,000 – $45,000. A bathroom remodel lands between $9,000 and $28,000.
Kitchen Remodeling on Older Highgrove Homes
Most kitchens we open up in Highgrove need more than new countertops. We regularly find undersized joists, outdated supply lines, and venting that doesn’t meet current county code. We quote for the work behind the walls, not just what you see. Cabinet installation runs $4,000 – $13,000. Countertop installation, including Cambria, Silestone, or Caesarstone, runs $2,000 – $6,500.
Bathroom Updates With Well and Septic In Mind
Adding a bathroom or expanding one in Highgrove often triggers a county Environmental Health review if it changes your water usage or waste load. We handle that sign-off as part of the job. Walk-in shower installation runs $4,500 – $12,000, and a tub-to-shower conversion runs $3,500 – $10,000. We’ll tell you before you sign whether your septic system can absorb the change.
Licensed General Contractor in Highgrove
A Licensed General Contractor in Highgrove carries the liability insurance, worker’s comp coverage, and county-recognized license required to pull permits and manage subcontractors legally on unincorporated county land. Doing major work here without that license puts the homeowner at risk: county inspectors won’t sign off, financing gets complicated, and unpermitted work complicates any future sale. We’re licensed and insured, and every Highgrove project gets permitted properly through Riverside County Building & Safety. Home additions run $45,000 – $130,000 in Highgrove. Detached ADU construction runs $90,000 – $220,000.
Detached ADUs and Outbuildings on Acreage
Highgrove’s larger rural lots are ideal for detached ADUs, shops, and guest houses. But county setbacks for wells and leach fields often dictate exactly where you can build. We scope those setbacks before you commit to a design, through partnerships with Abodu, Dvele, and Boxabl for prefab ADU construction. A garage conversion runs $30,000 – $80,000, depending on whether it’s a straight finish-out or a full structural upgrade with new foundation work.
Whole-Home and Exterior Scope
Since we’re not a single-trade remodeler, your Highgrove addition can include roofing, windows, siding, fencing, and hardscaping under the same contract. That means the grading plan, the roof tie-in, and the paver driveway all get coordinated as one build. It also means one team answers for the whole thing. Built to the standard your home deserves.

AfterCommon General Contractor Problems We See in Highgrove Homes
- Septic and well setbacks killing the building pad: On many Highgrove lots, the leach field and well head dictate where you can legally build. We survey those lines before design, not after.
- County Environmental Health review adding weeks: Any project touching water or waste lines needs separate county sign-off beyond the building permit. Contractors who don’t plan for this blow schedules.
- Floodplain and drainage requirements on open acreage: Highgrove’s wash areas and seasonal flash-flood risk mean grading and drainage plans must pass county review. We engineer for it up front.
- Wildfire-defensible detailing on edge lots: Homes on Highgrove’s periphery are in high-risk fire zones. The county requires defensible space and ignition-resistant materials that city contractors often overlook.

FAQs About General Contractor in Highgrove
Yes. Every ADU in Highgrove requires a Riverside County Building & Safety permit, plus county Environmental Health sign-off for any well or septic work. We handle both, including the dual-agency review that city-only contractors often miss. Call (855) 600-3192 and we’ll check your lot before you start designing.
Setbacks from your well head and leach field determine where you can legally place a foundation on a Highgrove lot. If either is too close, we re-engineer the pad location or foundation design, as we did on a recent ADU off Center Street. We identify these constraints before you pay for plans.
Sitework and utility work. Grading, drainage, septic and well tie-ins, and bringing materials and equipment across a large rural lot all add cost that city projects never carry. We scope these exact items in your written estimate, not after the fact. Call (855) 600-3192 for a line-item quote.
We pull every permit through Riverside County Building & Safety, schedule all inspections, and stand for the inspector on your behalf. If your project touches well or septic systems, we also handle the separate county Environmental Health review. You get one accountable team through the whole process.
Yes. We spec ignition-resistant siding, decking, and ventilation details that meet county requirements for high-risk zones on Highgrove’s edge lots. We’ll walk your property and tell you exactly what needs to change and what it costs. Call (855) 600-3192 for a free assessment.
