Fast, Reliable General Contractor Across Fontana
Hiring a general contractor in Fontana means finding someone who understands what this city throws at a house. We’re talking about Santa Ana winds ripping through the Cajon Pass at 70 mph, summer UV that bakes stucco and roof tile for months on end, and thousands of 1980s and 1990s tract homes now entering their second or third remodeling cycle. Milpitas Construction handles all of it: roofs, additions, ADUs, garage conversions, kitchens, bathrooms, hardscaping, and exterior work under one contract and one point of contact. Call (877) 752-4194 for a free estimate.
Why Milpitas Construction Is Fontana’s Preferred General Contractor Company
Fontana homeowners call us because we plan for conditions that coastal contractors never consider. Ken Stafford has built Milpitas Construction around full-scope accountability, the kind where the same crew managing your roof replacement also runs your kitchen remodel. We don’t hand you off to a rotating cast of subcontractors and hope for the best. From the roofline to the kitchen counter, one contractor, one conversation.
Our Fontana work skews heavily toward second-generation remodels on 15 to 30-year-old tract homes, plus a steady stream of room additions and ADUs. We know that a home in Hunters Ridge (92336) built in 1998 has different framing, stucco, and roof attachment than a 2005 build in Sierra Lakes (92337). That local knowledge changes how we spec materials, what we flag during the estimate, and which permits we pull before work starts. Estimates are free, and the phone number is (877) 752-4194.

Residential General Contractor in Fontana
Residential General Contractor work in Fontana is rarely a simple trade call. The city enforces the 2022 California Building Code with a Wind Exposure C designation for most of the 92336 and 92337 tract homes, which means roof edge metal, tile attachment, patio covers, and carports must be engineered for higher uplift than standard coastal specs. A residential general contractor here has to understand what that means for your project before the first permit is pulled. We do.
Typical residential general contractor scopes we run in Fontana include whole-home remodels, kitchen and bath renovations, room additions, and exterior packages that bundle roofing, windows, siding, and hardscaping. On a tract home in Southridge (92336) or Westgate (92337), the most common trigger is a family outgrowing the original floor plan. Room additions in Fontana generally run $45,000 to $130,000 depending on square footage, foundation type, and whether you’re tying into an existing slab or pouring new. ADU construction runs $90,000 to $220,000 for prefab or site-built units.
Planning a Room Addition or ADU
Fontana’s housing stock is largely slab-on-grade stucco tract homes, so additions usually mean saw-cutting into the existing slab, matching the stucco profile, and detailing tie-ins so wind and water don’t find the seam. We pull permits, run the engineered drawings, and schedule inspections so the final sign-off is real and documented. Unpermitted additions are a recurring problem in older Fontana homes; when we open a wall, we often find work that was never inspected. We fix that before it becomes a stall point on your remodel.
Whole-Home Renovation Coordination
A whole-home remodel in Fontana means coordinating roof work, stucco repair, window replacement, and interior finish work under one schedule. Our exterior-to-interior scope keeps a single crew accountable for the entire sequence. If you replace windows before re-roofing, you’re doing it wrong. We order the trades in the right sequence and spec the materials by name: GAF or CertainTeed roofing, James Hardie siding, Therma-Tru doors, Kohler fixtures, KraftMaid cabinetry. You know exactly what’s going into your home.
Hire a General Contractor in Fontana
Hire a General Contractor who understands Fontana’s wind zone and permit process, not just someone who can swing a hammer. Fontana sits at the mouth of the Cajon Pass, and Santa Ana events routinely peel fascia, lift roof field tiles, and tear unanchored patio covers off their posts. Our General Contractor team specs projects to survive that. When you hire us, you get one contract for the entire build, one point of contact, and a project manager who knows Fontana’s inspection process well enough to sequence work without stall days between trades.
Kitchen remodels in Fontana run $14,000 to $45,000 for a full gut and rebuild. Bathrooms run $9,000 to $28,000. Paver driveways from Belgard or Unilock run $7,000 to $18,000, and concrete runs $4,500 to $12,000. Those are real ranges for this market. If someone bids far below them, ask what’s missing, usually the engineer’s wind-uplift calc or the permit itself. We don’t leave those out.
Prefab and ADU Construction
Fontana homeowners looking at ADU construction should know this is a current specialty of ours, not a future offering. We work with manufacturers including Abodu, Dvele, Mighty Buildings, Boxabl, and Plant Prefab. Prefab ADUs can reduce on-site build time significantly, but the foundation, wind anchoring, utility trenching, and final inspection still have to meet Fontana’s code. We handle all of it under one contract.
Exterior Work Built for Cajon Pass Wind
Roof replacement in Fontana should never be quoted with coastal-standard edge metal. We specify wind-rated drip edge, enhanced tile fastening, and underlayment that holds during gust events. Fencing gets deeper post setting and heavier hardware. Patio covers and carports get engineered hold-downs. Vinyl fence from ActiveYards and Bufftech, aluminum from Jerith, paver work from Belgard, all installed to stay put through a Santa Ana.
Trusted Brands We Service in Fontana
We carry material lines from 50+ brand-name manufacturers, and we keep the ones most relevant to Fontana homes moving fast. Belgard pavers and retaining wall block for hardscaping projects across the 92336 and 92337 zip codes. ActiveYards and Bufftech vinyl fencing systems that handle Inland Empire sun without fading or cracking, plus Jerith aluminum for wind-exposed fence runs. Homeowners choose from proven contractor-grade tiers instead of guessing at a big-box store. Premium brands, proper installation, one accountable team.

AfterCommon General Contractor Problems We See in Fontana Homes
- Unpermitted patio covers and carports. Santa Ana winds expose these every year. A 70 mph gust tears an unanchored patio cover off its posts, and the insurance adjuster asks for the permit. If there isn’t one, the claim stalls.
- Coastal-standard roof edge metal on Cajon Pass-adjacent homes. Roofers who come up from Orange County spec standard drip edge and tile adhesive. It fails. We see repeated blow-offs on south-facing roof edges in 92336 and 92337.
- Stucco cracking on sun-exposed southern elevations. Fontana’s UV load dries stucco faster than coastal or even central LA homes. If the original build used thin base coat or skimped on control joints, the cracks open wide. Our patches match texture and install proper joint control.
- Unpermitted garage conversions stalling future remodels. The south side of Fontana (92335) has older stock with a high rate of informal garage conversions from the 1990s. When those homeowners try to sell or refinance, the unpermitted work shows up. We correct it and get final sign-off.

FAQs About General Contractor in Fontana
A new patio cover or carport in Fontana generally needs to meet the 2022 California Building Code Wind Exposure C uplift requirements for the 92336 and 92337 zip codes, which typically means an engineer’s calc and specific hold-down hardware. Coastal-standard anchoring won’t pass inspection here. We include the engineering and the hardware in every quote. Call (877) 752-4194 for a free estimate on a patio cover or carport built to Fontana’s actual wind load.
Documented compliance, meaning a permit with final inspection sign-off, gives your insurance carrier a real paper trail when you file a claim after a Santa Ana event. If the damaged structure was never permitted or the fix was never inspected, the adjuster has a reason to push back or deny. We walk every Fontana project through inspection so the compliance is documented, not just claimed. Call (877) 752-4194 if you need unpermitted work corrected before it becomes a claim problem.
Fontana’s older south-side housing stock (92335) and even some 1980s and 1990s tract homes have a high rate of unpermitted room additions and garage conversions because previous owners worked off the books. When we open those spaces for a remodel, the framing, electrical, or foundation often fails current code. We correct the work, pull the permits, and get final sign-off so your house is insurable and sellable. Call (877) 752-4194 for an assessment.
A compliant Fontana quote should include the engineer’s wind-uplift calculation where required, permit fees, inspection scheduling, wind-rated edge metal and fasteners on roofs, and hold-down hardware on any patio cover or carport. A cheap bid strips those items out and then hits you with a change order, or worse, skips them entirely and leaves you with a structure that won’t pass inspection. Our quotes are line-item and written. Call (877) 752-4194 for the real number.
Santa Ana winds out of the Cajon Pass routinely exceed 70 mph and hit south-facing roof edges and stucco walls hardest. That means Fontana roofs need wind-rated drip edge, enhanced tile fastening, and underlayment that holds during gust events, while stucco needs proper control joints and UV-stable materials so it does not crack open under heat and wind cycling. We were called to a 1998 stucco-on-wood-frame tract home in the Hunters Ridge neighborhood (92336) where a Santa Ana event had peeled back the fascia and lifted several field tiles on the south-facing roof. Our crew re-secured the underlayment, installed wind-rated drip edge and enhanced tile fastening per the engineer’s uplift calcs, then walked the homeowner through the inspection sign-off so the fix would be documented for their insurance carrier.
