Remodeling Company in Highgrove, CA
Home remodeling in Highgrove typically runs $9,000 – $130,000 depending on scope, with whole-house projects reaching the upper end and single-room updates starting well below. Because Highgrove is unincorporated Riverside County, every permit, inspection, and code check flows through the county’s Land Use Services office in Riverside rather than any local city hall. That jurisdictional reality shapes timelines, fees, and contractor expectations here in ways that don’t apply just across the border in the City of Riverside or Grand Terrace. We’re Penhallow Remodeling, and we build that county-schedule buffer into every Highgrove project from day one. Call (936) 259-2607 to talk through what you’re planning and get a written price before any work starts.
Why Highgrove Homes Are Different
Highgrove’s housing stock is largely modest, mid-20th-century working-class homes built during the 1940s through the 1960s, many on slab-on-grade foundations laid when this area supported citrus agriculture and light industry. Those original wood framing and roofing systems often predate current Riverside County seismic and energy codes, which means any substantial remodel triggers upgrade requirements that add scope and cost.
The climate here is equally demanding. Summer temperatures routinely exceed 105°F in this Inland Empire semi-arid corridor, accelerating concrete curing times and stressing roofing materials during exterior phases. Proximity to the Santa Ana River also places portions of Highgrove within FEMA-designated flood hazard zones, requiring elevation certificates and flood-resistant construction standards on affected parcels. Experienced contractors here know to sequence exterior work for cooler months and to verify flood zone status before breaking ground.
Our Main Highgrove Services
Highgrove homeowners call us most often for two types of projects: comprehensive whole-home updates that bring aging mid-century structures up to modern living standards, and targeted room renovations that address specific functional failures without full gutting. Here is how we approach each.

Bathroom Remodeling in Highgrove
Bathroom remodeling in Highgrove means working within compact 1940s – 1960s footprints where original plumbing may be galvanized steel or cast iron nearing failure.

Every bathroom project gets a written line-item price and our written guarantee before demolition begins. Bathroom Remodeling in Highgrove

Kitchen Remodeling in Highgrove
Kitchen remodeling in Highgrove often involves opening up closed-off mid-century layouts to create functional flow while addressing aging electrical service that can’t support modern appliance loads. We specify cabinetry from KraftMaid or Wellborn, countertops from Cambria, Silestone, or Caesarstone, and fixtures from Kohler and Moen that carry their own manufacturer warranties alongside our 365-Day Done Right Promise. The written price you receive covers everything from permit pulling through final county inspection. Kitchen Remodeling in Highgrove

Home Remodeling in Highgrove
Home remodeling in Highgrove means working with the specific conditions of unincorporated Riverside County: county permits, county inspectors, and county code enforcement that operates from a central office serving a vast territory rather than a local city hall down the street. The typical Highgrove home was built between the 1940s and 1960s on a slab foundation, often with original systems that don’t meet current seismic or energy standards. Our Home Remodeling process starts with a thorough assessment of what county upgrades will be triggered, builds realistic inspection buffers into the schedule, and delivers a written price that accounts for every phase before we pull the first permit.
Whole House Remodel
Signs you need it
Your home still has original knob-and-tube or early Romex wiring, a failing roof with multiple leak points, unpermitted additions from prior owners, or a floor plan that doesn’t function for how your family actually lives.
What it costs in Highgrove
A whole house remodel in Highgrove typically runs $45,000 – $130,000 for a home addition scope, with full gut renovations of larger homes reaching the upper end and phased projects spread across multiple years starting lower.
How we do it
We start with a structural assessment and Riverside County code compliance review, develop phased plans that minimize displacement, pull permits through the county’s Land Use Services office, and schedule inspections with realistic lead-time buffers built in.

How long does a whole house remodel take in Highgrove?
Most whole house remodels in Highgrove take 4 – 8 months from permit approval to final county inspection, with unincorporated status adding 2 – 4 weeks to initial permit review and inspection scheduling compared to incorporated cities nearby. We build that buffer into every written schedule we provide. Call (936) 259-2607 for a timeline specific to your project – estimates are free.
Will remodeling trigger required upgrades to old systems?
Yes, Riverside County Building & Safety typically requires seismic bracing, electrical service upgrades, and energy-efficiency improvements when remodels exceed 50% of a home’s value or involve structural modifications, which is common in Highgrove’s 1940s – 1960s housing stock. We identify these triggers during our initial assessment and include all required upgrades in your written price so nothing surprises you mid-project. Call (936) 259-2607 to schedule that assessment.

FAQs About Remodeling Company in Highgrove
We pull every required permit through Riverside County Building & Safety as part of our standard service, included in your written price. Because Highgrove is unincorporated, this means dealing with the county’s Land Use Services office in Riverside rather than any local city hall, which we handle entirely so you don’t navigate that system yourself.
Properties near the Santa Ana River in Highgrove fall within FEMA-designated flood hazard zones, requiring elevation certificates and flood-resistant construction materials for any substantial improvement. We verify flood zone status during our initial site assessment and include any required mitigation in your written scope and price.
Riverside County inspectors serve a vast unincorporated territory stretching from rural areas to suburban pockets like Highgrove, with fewer inspectors per square mile than incorporated cities maintain. We build 2 – 4 extra weeks into every Highgrove project schedule to accommodate realistic inspection windows, and we coordinate directly with the county so you don’t spend days waiting for callbacks.
