Fast, Reliable General Contractor Across Sunnyvale
Sunnyvale homeowners planning a kitchen remodel, a detached ADU, a two-story addition, or a whole-home renovation need one contractor who can handle the entitlement process, the construction, and the hardscape without farming pieces out to strangers. Our General Contractor team manages every phase under a single contract, from demolition through final inspection. That matters in Sunnyvale, where a post-war ranch on a 6,000-square-foot lot in 94087 can sit three blocks from a teardown going up as a 3,200-square-foot new build in 94086. Call (833) 400-1314 to schedule a free estimate.
Why Silver Line Contractors Is Sunnyvale’s Preferred General Contractor Company
We work throughout the 94085, 94086, 94087, and 94088 ZIP codes, and we know which projects hit city review and which fall under county jurisdiction. Homeowners in the Orchard Gardens and Cherry Orchard tracts near El Camino Real deal with tree-preservation rules that affect setback clearances. Properties pressing against the Sunnyvale-Saratoga corridor often carry county well and septic requirements that a city-tract contractor never sees. That local knowledge changes how we quote, what we pull permits for, and how we sequence work.
Noel Carvalho runs our projects with a simple rule: scope it right before the first check clears. Our Sunnyvale customers tell us the same thing, that the estimate phase is what separates a clean build from a permit fight. We write line-item quotes using the exact material allowances we’ll use on site, whether that’s Silestone counters in a new ADU kitchen or GAF shingles on a reroof. You deserve to know what you’re paying for before we cut anything open.
We’re General Contractor specialists, not a handyman crew with a bigger truck. That means a project in Sunnyvale gets a dedicated lead, a written schedule, and a point of contact who answers the phone. You won’t chase down a drywall sub who disappeared for a week. You’ll call us, and we’ll know where your project stands.
Styles & brands we work with
Construction Company in Sunnyvale
As a Construction Company working Sunnyvale’s older acreage and tract-home parcels, we handle the structural side of a project before the finishes get picked. That includes foundation work on slab-on-grade ranches, post-and-beam roof modifications on Eichler-influenced homes, and detached structures that need their own pad, grading, and drainage design. On a no-city-utilities lot off the Sunnyvale-Saratoga edge, a shop or detached ADU is not a standard build. It’s a county review project.
Slab-On-Grade Ranch Additions
Most 1950s-era Sunnyvale homes sit on slabs, not raised foundations. Cutting into one for a bathroom addition or a kitchen island relocation means saw-cutting concrete, rerouting plumbing under the slab, and sometimes adding a thickened edge where a new beam lands. We quote this work line by line, with the exact linear feet of saw cut and the plumbing rough-in broken out.
Detached ADU and Shop Pads
An acreage outbuilding in Sunnyvale means one thing first: where can the pad legally sit? Santa Clara County well and septic setback rules often dictate the answer, not the client’s preferred location. We pull the county health review, site the pad around approved setbacks, and only then do we draw grading and drainage plans. Ordering concrete before that sign-off is how five-figure mistakes happen.
Remodeling Contractor in Sunnyvale
As a Remodeling Contractor in Sunnyvale, we take an existing ranch or two-story and reshape it around how you actually live. A full kitchen remodel in the 94087 ZIP code runs $14,000 to $45,000 depending on cabinet line, counter material, and whether we’re moving gas and water. A bathroom remodel runs $9,000 to $28,000. A whole-home renovation that opens up a post-and-beam interior can hit six figures, but the line items stay clear.
Kitchen and Bath Overhaul
We pull kitchens out of the 1960s and bring them current, often working around the original slab plumbing which we don’t move unless you want the cost of saw-cutting. Cambria or Caesarstone counters, KraftMaid or Wellborn cabinets, and Delta or Kohler fixtures sit at different budget tiers, and we show you the real price spread before you commit.
Whole-Home Remodel with Exterior Scope
Sunnyvale homeowners frequently ask us to reroof, replace single-pane windows, and re-side with James Hardie in the same contract as an interior remodel. That’s our normal scope, not a stretch. One contract, one schedule, one set of inspections. From the roof down to the driveway, as we say.
Trusted Brands We Service in Sunnyvale
We build with brands that have real manufacturer backing, and we stock and order for Sunnyvale projects the same way. For ADUs and detached structures, we work with Plant Prefab, Dvele, and Boxabl systems when the lot and county approvals support that path. For cabinets, KraftMaid and Wellborn. For counters, Cambria, Caesarstone, and Silestone. Roofing carries GAF, CertainTeed, and Owens Corning warranties when we install those shingle lines. The point is choice backed by a manufacturer who stands behind the product. If you’re in Sunnyvale and want a specific brand, tell us at estimate time. We’ll price it honestly.

AfterCommon General Contractor Problems We See in Sunnyvale Homes
- County setbacks kill a planned ADU or shop. We see owners pay for plans before anyone checks well-to-septic separation on Santa Clara County’s records. The lot can’t support the sited footprint, and the plans get redrawn at the client’s expense.
- Wet-season access stalls long driveways. On a big unincorporated lot, a delivery truck that can’t get down a single-lane easement in January means materials sit on the road, and your draw schedule slips. We plan deliveries around seasonal access, not just the construction calendar.
- Grading pushes water the wrong way. A stamped drainage design isn’t optional when stormwater could move toward a neighbor’s slope or under a new structure. Sunnyvale’s rainy season concentrates the risk into a few months, and a failed drainage sign-off stops inspections cold.
- Original single-pane glass and slab plumbing surprise remodels. Post-war tract homes hide cast-iron drain lines under the slab and aluminum windows in the walls. We budget for what we might find, and we show you the contingency as a line item, not a vague number.
Pricing for General Contractor in Sunnyvale, CA
Sunnyvale project pricing tracks scope and jurisdiction more than anything else. A city-tract kitchen remodel runs $14,000 to $45,000. A detached ADU on an open lot runs $90,000 to $220,000, and the county review portion is part of that, not an add-on surprise. What moves the number: which brands we’re installing, whether we’re cutting slab, how far the delivery trucks have to travel, and whether grading and drainage need stamped engineering. A paver driveway runs $7,000 to $18,000, concrete $4,500 to $12,000. A garage conversion runs $30,000 to $80,000. A home addition runs $45,000 to $130,000. Here’s how some of that breaks down:
| Project Type | Sunnyvale Price Range |
|---|---|
| ADU Construction | $90,000 – $220,000 |
| Home Addition | $45,000 – $130,000 |

FAQs About General Contractor in Sunnyvale
In most cases, both, but the county review is what most homeowners miss. Within Sunnyvale city limits, the city’s building department handles permits and plan check. On unincorporated acreage just outside the city, Santa Clara County handles the building permit, and the county health department has to sign off on well and septic setbacks before a grading or foundation plan gets approved. If your property gets water and sewer from the city, you’re likely city-permitted only. If you’re on a well and septic, expect the county review. Call (833) 400-1314 and we’ll tell you which jurisdiction applies to your parcel before you spend money on plans.
They can add $5,000 to $15,000 or more in design, review, and re-siting costs if the initial pad location doesn’t meet separation requirements. The county requires minimum distances between a well, a septic tank, and a leach field. If your preferred shop or ADU location violates one of those, the building has to move, and moving it changes grading, drainage, foundation excavation, and material quantities. That’s why we check setbacks before quoting the pad. A smart client pays for the review first and the plans second. Call (833) 400-1314 if you’re looking at an acreage parcel.
We walk the lot, check existing slope and drainage patterns, and flag any stormwater path that might need a stamped drainage design. On a flat Sunnyvale parcel, simple swales and a compacted base might be enough. On a sloped lot, or one where water drains toward a neighbor’s property or a sensitive slope, we scope the engineering time, the drainage pipe, the catch basins, and the inspection sign-off into the quote. We don’t guess. The rainy season is only a few months away every year. Call (833) 400-1314 and we’ll walk your lot together.
It hits in three ways: delivery scheduling, staging area, and weather. A single-lane easement or a long gravel drive limits which trucks can reach the pad and how close they can get. If a roof-truss delivery can’t make the turn in wet weather, that delivery date moves, and everything behind it moves too. We build a wet-weather delivery buffer into acreage project schedules and line up local staging options where the access won’t support a full semi. Your draw schedule reflects reality, not an optimistic calendar. Call (833) 400-1314 to get a real timeline.
Yes, and that’s the standard way we’d recommend it. One contract, one schedule, one point of contact for the interior remodel, the exterior work, the ADU, and the hardscape. On a lot where the main house needs a kitchen and bath gut-renovation and you also want a detached ADU, combining the scope means the grading, drainage, and utility runs can be planned once instead of twice. We scoped and built exactly that type of project on an unincorporated lot off the Sunnyvale-Saratoga corridor. The well sat closer to the proposed leach field than the county allows, so we re-sited the pad, pulled the septic review through Santa Clara County, and built the subfloor and rough-in around the approved footprint. Cambria counters in the ADU kitchen and a Kohler rough-in in the bath were held as allowances until the county sign-off cleared. That’s how the scoping protects you. Call (833) 400-1314 to schedule your free estimate, and we’ll tell you what applies to your parcel.
