Fast, Reliable General Contractor Across Home Gardens
Square One Builders manages full-scope remodels and additions across Home Gardens, CA, from the first county permit check to the final walk-through. We know what opening up a 1960s ranch off Ontario Avenue actually turns up, and we price for it before the first wall comes down. If you’re planning a kitchen, bath, whole-home remodel, or ADU in the 92879 ZIP, call us at (877) 688-9930 and we’ll give you a straight answer on scope and cost. One contractor, every system. That’s how a Home Gardens remodel should run.
Your remodel, fully managed. We handle structural work, roofing, cabinetry, countertops, plumbing fixtures, windows, hardscaping, and ADU additions under a single contract, so nothing falls between trades and nobody points fingers when a surprise shows up behind the drywall.
Why Square One Builders Is Home Gardens’s Preferred General Contractor Company
Home Gardens homeowners call us because we understand the county permit path that governs every project here. This is unincorporated Riverside County, not city jurisdiction, so the approval process, inspection scheduling, and as-built verification requirements are different from what a Corona or Riverside contractor might assume. We run that path weekly for Home Gardens remodels, additions, and garage conversions, and we sequence the job so the permit doesn’t stall your demo.
Our Home Gardens customers consistently tell us the same thing: they appreciated that we didn’t flinch when a surprise appeared, and that our written change orders made the cost clear before we touched anything. Brent Calloway built Square One Builders around that principle. Scoped, planned, and executed from the ground up with a single accountable team.
We carry Licensed & Insured status, we write line-item quotes, and we don’t treat allowances as fixed prices. When a Home Gardens wall opens to reveal cloth-wrapped wiring or a notched header, you’ll know exactly what the repair costs before we proceed.
Styles & brands we work with
Construction Company in Home Gardens
Square One Builders operates as a full-scope Construction Company in Home Gardens, handling everything from structural modifications and foundation repairs to full interior build-outs and exterior system replacements. Homeowners bring us in when a project is too big for a specialty trade and too interconnected to coordinate piecemeal. A typical Home Gardens kitchen remodel runs $14,000 – $45,000, a bathroom remodel $9,000 – $28,000, and a home addition $45,000 – $130,000 depending on size, finishes, and what the walls reveal once they’re open.
When your Home Gardens home was built between the 1950s and 1970s, the structure has lived through decades of Santa Ana wind cycles and DIY modifications. We approach every job expecting the unexpected, and we put that expectation into the contract so you’re never ambushed by a number you didn’t approve.
Structural and Foundation Scoping
Before finish materials are ever ordered, we verify the bones. Older Home Gardens ranch homes often have undersized headers, settled foundation sections, or framing that was modified years ago without permits. We inspect first, document what’s there, and bring the county into the loop when an as-built condition needs to be resolved.
From the Ground Up Builds
Additions and ADUs on Home Gardens lots come with a specific constraint: many parcels were never platted for the structures now sitting on them. That means set-back verification, lot-line review, and a county as-built check are routine first steps before we submit drawings. We’ve done it enough to keep the process moving without surprises.
Remodeling Contractor in Home Gardens
As a Remodeling Contractor in Home Gardens, we take interior renovation projects from selective demolition through finish carpentry, tile, cabinetry, countertops, plumbing fixtures, and paint. A small kitchen remodel here typically runs $9,000 – $20,000, a walk-in shower installation $4,500 – $12,000, and a tub-to-shower conversion $3,500 – $10,000. The range depends on whether we’re replacing finishes or opening up systems that haven’t been touched since the house was built.
What makes Home Gardens remodels different is the housing stock itself. Many homes were owner-built or heavily modified over the decades, so behind a dated kitchen you often find wiring and plumbing that don’t meet current code. When we open a wall, we know how to respond: stop, verify, price the correction in writing, and only then close it back up.
Full-Scope Kitchen and Bath Packaging
We coordinate every sub-system: cabinets, countertops, plumbing fixtures, tile, lighting, and ventilation. Because we’re theGeneral Contractor of record, you get one accountable team, not five different specialists with five different schedules. We spec the right material for your project from our catalog of 50+ vetted brands, including KraftMaid cabinetry, Cambria or Silestone countertops, and Kohler or Moen fixtures.
Whole-Home and Multi-Room Renovations
When a Home Gardens homeowner wants to update several rooms at once while keeping the house livable, we phase the work and write the draw schedule around inspection sign-offs. No mid-stream chaos, no mystery invoices. We also hold James Hardie siding, CertainTeed roofing, and PGT windows in our sourcing lineup for exterior work that often runs alongside a major interior remodel.
Trusted Brands We Service in Home Gardens
We source and install from a portfolio of 50+ nationally recognized brands, and for Home Gardens homeowners that means you’re not limited to whatever a single trade has on the truck. Roofing comes from GAF, CertainTeed, and Owens Corning. Cabinetry from KraftMaid and Wellborn. Countertops from Cambria, Silestone, and Caesarstone. Windows from PGT and Therma-Tru. Plumbing fixtures from Kohler, Moen, Toto, and Grohe. We stock common replacement parts locally for fast turnaround on Home Gardens punch-list items, and we can order any brand in the catalog without switching contractors mid-job.

AfterCommon General Contractor Problems We See in Home Gardens Homes
- Unpermitted additions that block a permit. Converted carports, detached garage second units, and rear shop buildings are common off Ontario and Magnolia. The county requires an as-built verification before any new permit can issue, and we run that first so your remodel doesn’t stall mid-demo.
- Cloth-wrapped wiring and outdated panels on 1960s ranches. Open a kitchen wall in an older Home Gardens home and you’ll usually find wiring that predates modern codes. Once the county sees it, an electrical upgrade is mandatory, and we write that allowance into the contract from day one.
- Wind-stripped roofing and fence panels from Santa Ana events. Seasonal wind gusts rip shingles and pull fence sections loose. We replace roofing with CertainTeed or Owens Corning systems and install fencing from Master Halco or Ameristar, then make sure the permits and wind-loading details are right for this exposure.
- Notched or undersized framing behind previous DIY work. A lot of Home Gardens homes were heavily modified by owners. We find load-bearing headers notched for plumbing, missing junction boxes behind drywall, and framing that doesn’t meet current span tables. We fix it with a written change order, never a surprise invoice.
Pricing for General Contractor in Home Gardens, CA
Home Gardens pricing sits slightly below what you’d pay in newer Corona developments, mostly because the county permit path is slower and the housing stock is older, which means more discovery work gets built into the estimate up front. Here’s what you can expect:

|---|---|
| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |

FAQs About General Contractor in Home Gardens
Home Gardens is an unincorporated Riverside County community, so all building permits run through the Riverside County building department, not a city hall. The review queue and inspection scheduling follow county procedures that differ from neighboring cities like Corona. Call (877) 688-9930 and we’ll walk you through the exact path for your specific project.
We stop work, document the condition, and bring the county in for an as-built sign-off if needed. Then we price the repair as a written change order and get your approval before proceeding. No surprises, no unauthorized work, and no closing the wall until the county has seen what’s behind it.
Yes. We schedule every county inspection, meet the inspector on site, and tie the draw schedule to inspection sign-offs so you’re never paying ahead of the work actually approved. Our crews handle the full process for Home Gardens remodels from rough-in through final.
Yes, and this is one of the most common projects we run in Home Gardens. The first step is an as-built verification through the county to confirm the structure’s current condition and setback compliance. Typical ADU construction here runs $90,000 – $220,000, and a garage conversion $30,000 – $80,000 depending on the existing shell.
We don’t pretend the surprises won’t come; we budget for them. Allowances are written as ranges, not fixed numbers, and every discovery gets priced in writing before we proceed. That’s the only honest way to remodel older Home Gardens housing stock without blowing the budget. Call (877) 688-9930 for a free estimate and we’ll show you exactly how it works.
