Fast, Reliable General Contractor Across Sunnyvale
Hiring a general contractor in Sunnyvale usually means one of two things: you own an original 1950s rancher that needs a major addition or full remodel, or you bought a newer townhome near downtown and want interior work done without disturbing the neighbors. Either way, San Mateo Construction has handled it. We know the permit process at Sunnyvale City Hall, we’ve worked through the tree-survey requirements in 94087, and we’ve staged materials on streets where parking is tighter than most homeowners expect. Call (855) 901-7266 for a free estimate from a contractor who already knows the road you live on.
Why San Mateo Construction Is Sunnyvale’s Preferred General Contractor Company
Homeowners in Sunnyvale keep calling us for projects that other contractors won’t touch, or ones they’ve quoted badly, or ones that stalled in permitting. The single-story-to-two-story setback transition rules catch a lot of people off guard. We’ve walked enough Sunnyvale additions through the city’s engineered foundation retrofit reviews to know what gets flagged before we ever start drawing plans. That’s the difference between a permit that takes three weeks and one that takes five months.
Our team, led by Noel Carrington, runs a true single-source operation: one contract covers roof, foundation, framing, electrical, plumbing, tile, cabinetry, windows, hardscaping. Our Sunnyvale customers like that there’s no finger-pointing between trades mid-project. If something moves on the schedule, you hear it from us, not from a sub you’ve never met. Reviews from Sunnyvale neighborhoods consistently mention how we keep the site clean and the neighbors informed.
For tight-lot projects off El Camino Real or in the Cherry Chase area, we plan staging before we plan demolition. A full dumpster, a material drop, and two trucks don’t fit in every driveway. We map it out first, then quote. That’s why people in 94086 and 94087 call us when they’re weighing a General Contractor for a major remodel rather than juggling five separate vendors.
Styles & brands we work with
Hire a General Contractor in Sunnyvale
Hire a General Contractor when your Sunnyvale project crosses more than two trades, or when the building department requires stamped engineering. A kitchen remodel that moves plumbing and load-bearing walls, a room addition on a clay-heavy lot, a garage conversion that triggers a foundation retrofit. That’s where our scope fits: we handle the structural work, the trade coordination, and the permit paperwork under one accountable contract. Typical Sunnyvale projects start around $45,000 for a modest addition and run up to $220,000 for a full prefab ADU. The range depends on access, foundation work, and what the city requires on your specific parcel.
Whole-Site Planning and Site Management
Before you sign a contract, we walk the site with materials in mind. Where does the Roof Replacement dump load go? Do we run the paver pallets through the side gate or the garage? On a 5,000-square-foot Sunnyvale lot, the answer usually involves coordinating deliveries in sequence, not everything at once. We keep the street passable and the neighbors able to back out of their driveways.
Permit Pulling and Inspection Coordination
Sunnyvale Building and Safety handles the permits, but we handle the conversation. We prepare the plans, coordinate the engineers, schedule the tree survey if ordinance triggers it, and sit through the inspections. For second-story additions in 94087, that often means a foundation retrofit review before anything gets built. We plan for it in week one, not week ten.
General Contractor Services in Sunnyvale
General Contractor Services in Sunnyvale cover everything from roofline to foundation. We’re the single accountable builder on full home remodels, additions, ADU construction, kitchen and bath work, window and door replacement, siding, deck construction, paver driveways, and fencing. One contract. A mid-range kitchen remodel in Sunnyvale typically runs $14,000 to $45,000, while a full bathroom remodel lands between $9,000 and $28,000. Those prices reflect the market here: teardown-heavy demand, clay-soil foundation work on older slabs, and tight-lot logistics around downtown and Peery Park.
Whole Home Remodel and Addition
This is the work Sunnyvale calls us for most. A 1950s stucco rancher gets a second story, or a ground-floor addition off the back. We coordinate the engineer, the foundation retrofit, the framing, the re-roof, the windows, the siding, the interior finishes. Material selection runs from James Hardie siding and GAF or Owens Corning roofing on the exterior to KraftMaid or Wellborn cabinetry inside.
ADU and Garage Conversion
Sunnyvale’s ADU-friendly zoning pushed a lot of homeowners to convert a garage or build a backyard unit. We work with prefab manufacturers like Abodu and Dvele, and we also do traditional stick-built ADUs. Garage conversions in Sunnyvale commonly trigger a foundation retrofit when original redwood posts and pier foundations from the orchard era are exposed. We plan for that cost and that timeline up front.

AfterCommon General Contractor Problems We See in Sunnyvale Homes
- Original orchard-era foundations. Homes built in the 1950s and early 1960s on former cherry and apricot orchards often sit on redwood posts and pier foundations. Clay-heavy soils expand and contract through wet winters and dry summers, and after 60 years the piers shift. Any major addition needs an engineered retrofit before the city will sign off.
- Tight-lot access and parking. Many Sunnyvale lots are 5,000 to 6,000 square feet with narrow driveways. Dumpsters, material deliveries, and trade vehicles compete for the same space. Without a staged delivery plan, the street gets blocked, neighbors complain, and the project stalls on a code enforcement complaint.
- Second-story setback transitions. Converting a single-story rancher to two stories is not a simple vertical extension in Sunnyvale. The city’s setback transition requirements can force design revisions, and homeowners who didn’t plan for that find their permit months behind schedule before demo ever starts.
- Tree-preservation ordinance conflicts. Sunnyvale’s tree ordinance protects certain mature trees, and a tree survey may be required before grading or foundation work. If the survey finds a protected root zone in your addition footprint, the design changes or the tree report goes to a hearing. That adds time and cost most quotes don’t include.

FAQs About General Contractor in Sunnyvale
We sequence material deliveries based on what phase we’re in, not what’s easiest for the supplier. Framing lumber arrives first, roofing materials after, interior finishes in smaller loads. On tight lots in 94086 and 94087, we stage in your driveway or garage and keep the street clear unless the city has approved a temporary encroachment permit. Call (855) 901-7266 if you’ve got a specific lot constraint, and we’ll tell you how we’d handle access before you’re under contract.
A second-story addition requires building permits, structural engineering, and often a tree survey plus an engineered foundation retrofit if the original piers don’t meet current code. Sunnyvale’s setback transition rules may also trigger design review. We handle the full permit package for you and plan the timeline around city review times.
We work within Sunnyvale’s posted construction hours and schedule loud phases like demolition, jackhammering, and framing cuts inside legal windows. For dense townhome developments near downtown, we post advance notice for neighbors and keep subcontractors on the same schedule. If there’s a complaint, we fix it before it becomes a work stoppage.
Party-wall work, where your wall is also your neighbor’s wall, requires written notice and sometimes a signed agreement before demolition starts. We handle the notice and coordination, and we bring in an engineer if the structural wall needs openings. Skipping this step creates disputes and potential legal exposure in dense developments.
Access drives labor hours. If a dumpster can sit in the driveway and trades can park within a block, the job costs less. If materials have to be hand-carried through a side yard or we need an encroachment permit for the street, that adds labor and time to the quote. We’ll tell you exactly which scenario applies to your property when we walk it.
Ready for a real number? Call (855) 901-7266 and ask for a free estimate. We’ll walk your Sunnyvale property, talk through the scope, and give you a fixed, line-item quote with no change orders unless you change the scope. From roofline to foundation, one contractor, one contract.
