Remodeling Company in Highgrove, CA
Home renovation in Highgrove means working with Riverside County permitting, septic and well systems, larger irregular lots, and homes that were built across six or seven different decades. Square One Builders has served Highgrove since 2014, managing full-scope remodels and additions under one contract so homeowners never juggle separate trades. Call (877) 688-9930 to talk through your project and get a free estimate.
Why Highgrove Homes Are Different
Highgrove sits in the unincorporated foothills between Riverside and San Bernardino, and that unincorporated status changes how every project is permitted and built. There is no city building department here. Plan checks, inspections, and approvals all run through Riverside County, which means setbacks, grading, and utility connections get scrutinized lot by lot. A kitchen remodel on one street might need a septic capacity review, while a bathroom addition three blocks away needs a well-flow test before the county signs off. Nothing about Highgrove construction is cookie-cutter.
The housing stock reflects that. You will find 1950s ranch homes, 1970s single-story builds, and scattered parcels with outbuildings, detached garages, and older additions that were never permitted. Many lots are larger than typical Inland Empire subdivisions, and quite a few still operate on private septic and well systems that were never connected to municipal infrastructure. Summer heat routinely pushes past 100°F, and Santa Ana winds stress roofing, exterior coatings, and any curing concrete. When we start a renovation in Highgrove, the site conditions drive the plan as much as the floor plan does.
That county-controlled, site-specific reality is exactly why homeowners here benefit from a general contractor who manages the entire scope. Permits, site work, structural changes, and finish trades all have to coordinate around constraints that a tract-home remodeler never sees. We handle that from the ground up.
Styles & brands we work with
Our Main Highgrove Services
Most Highgrove homeowners reach out for one of two things: a full general-contract scope that spans multiple systems, or a complete home remodel that touches kitchens, bathrooms, and living space at once. Both start with the same conversation about your lot, your permits, and your budget.
General Contractor in Highgrove
Highgrove projects rarely fit a standard playbook. A general-contract scope here often includes structural work on an older ranch home, a detached shop or garage conversion, site grading around an irregular lot, and finish trades that all need to work around county inspections. When multiple systems are involved, one accountable contractor is what keeps the job moving. We coordinate every trade, every permit, and every material order under one contract. If you are planning an addition, a major structural change, or a whole-home project, start with our General Contractor in Highgrove page to see how we scope and manage that work.
Home Remodeling in Highgrove
Remodeling a Highgrove home often means working inside an older structure where plumbing, electrical, and framing were installed under codes that no longer apply. Kitchens and bathrooms in these homes frequently hide surprises behind the drywall: galvanized supply lines, undersized circuits, or framing that needs correction before new cabinets and tile go in. We plan for that before demo starts. A single remodel in Highgrove can involve county permit revisions, structural fixes, and modern fixture and finish selections all at once. Read more about how we approach that on our Home Remodeling in Highgrove page.

Home Renovation in Highgrove
Home renovation in Highgrove is rarely a simple cosmetic update. Older ranch homes and semi-rural properties here often need septic and well coordination, structural corrections, and exterior systems work before interior finishes make sense. That is why we scope renovation as a full home project, not a single room. As a Home Renovation contractor serving the 92313 ZIP code since 2014, we sequence the work so county inspections, site constraints, and material lead times never stall the project.
Home Renovation Contractors
Signs you need it
Multiple rooms are outdated, the home has unpermitted additions that need correction, or the layout no longer fits how your family lives.
What it costs in Highgrove
A whole-home renovation in Highgrove typically runs $45,000 to $130,000 depending on square footage, structural work, and the condition of existing systems.
How we do it

Home Renovators
Signs you need it
You are planning a kitchen plus a bathroom plus flooring all at once, or you have multiple permits that need to be pulled and coordinated together.

Most full-home renovation packages in the 92313 ZIP code land between $45,000 and $130,000, with kitchens and bathrooms driving the largest share.

What Home Renovation Costs in Highgrove
| Item | Typical range in Highgrove |
|---|---|
| Kitchen remodel | $14,000 – $45,000 |
| Bathroom remodel | $9,000 – $28,000 |
| Home addition | $45,000 – $130,000 |
How long does a whole-home renovation take in Highgrove?
Most whole-home renovations in Highgrove take four to eight months. County inspections and septic or well reviews can add time, so we build those waits into the schedule before demo begins. Call (877) 688-9930 for a realistic timeline for your lot.
Does the county permit review change a renovation budget?
Yes. Highgrove is unincorporated, so Riverside County reviews grading, septic, and setbacks lot by lot. Required corrections can shift budget. We scope those costs upfront and pull permits before work starts. Call (877) 688-9930 for a line-item estimate.

What Highgrove Customers Say
"He caught an error in the engineer's drawings before it got framed, which would have been an expensive thing to discover later."
— Lucia Martinez"Allowances in the contract were realistic rather than artificially low to make the bid look good."
— Colleen Bennett"The foundation survey came back dead on. Everything downstream of that being square is the reason the rest of the build went smoothly."
