Fast, Reliable General Contractor Across San Martin
If you’re planning a remodel, addition, or ADU in San Martin, the first question is usually who pulls the permit, and the second is what it will cost. The answer to the first matters more than most homeowners expect: because San Martin is unincorporated, your building permit flows through Santa Clara County, not a city planning desk. A General Contractor with local experience knows that on acre-plus lots, a simple addition can trigger septic clearance, well setbacks, and agricultural grading review before the first inspection gets scheduled. We work that process every month. Call us at (833) 382-8544 and we’ll walk you through what your property actually needs.
Gold Star Contractors handles the full scope: kitchens, bathrooms, whole-home remodels, additions, garage conversions, and ADU construction, plus exterior systems like roofing, windows, fencing, and hardscaping. One contractor. Every system. No handoff gaps. We serve the 95046 zip code and the rural roads that define San Martin, from properties along Monterey Road to homes tucked behind orchard rows east of the freeway.
Why Gold Star Contractors Is San Martin’s Preferred General Contractor Company
San Martin homeowners don’t want to juggle a tile contractor, a roofer, a window crew, and a septic consultant. They want one accountable team that knows how these systems connect, and that’s exactly what we deliver. Our work here spans older ranch homes, custom builds on former farmland, and everything in between. We know which lots will need dust control, which driveways can’t handle a delivery truck without staging, and which additions will pull a county comment about well setbacks before framing starts.
Our customers in San Martin consistently point to two things: we show up when we say we will, and we keep a written scope of work with allowances and a draw schedule tied to inspection sign-off. That matters on a constrained site where the neighbor’s fence is six feet from your foundation and the county inspector wants to see the septic clearance before you pour. Noel Carranza leads the team, and the standard is simple: permit pulled, inspections passed, materials specified before we start, and no handoff gaps between trades.
We’re not the cheapest quote in South County, and we don’t try to be. We’re the contractor that keeps the schedule honest, the site clean, and the scope clear. That’s what protects a five-figure remodel on a rural lot with county oversight.
Styles & brands we work with
Remodeling Contractor in San Martin
Remodeling Contractor work in San Martin usually means working inside an existing ranch-style home while the property keeps functioning around it, or taking a dated interior down to studs on a lot with real constraints. We handle kitchens, primary baths, whole-home renovations, and the structural surprises that come with older framing. A full kitchen remodel in San Martin typically runs $14,000 to $45,000, while a small bathroom remodel sits in the $5,000 to $12,000 range. The labor and material mix depends on how much plumbing and electrical you’re moving, and whether the county wants anything addressed while walls are open.
We’re fluent in the fixture and finish brands that hold up in a house that gets real use. Toto toilets and bidet systems, Schluter waterproofing systems in showers, Sterling tubs and surrounds, American Standard plumbing. We specify the brand, manage the install, and stand behind the result.
Kitchen and Bath Scope
A San Martin kitchen remodel often starts with removing a dated layout in a home built decades ago, then reworking an island, cabinet run, and countertop within existing walls. Cabinet installation alone runs $4,000 to $13,000, and countertop work adds $2,000 to $6,500 depending on slab selection and fabrication. We coordinate electrical, plumbing, and tile so the job doesn’t stall between trades.
Whole-Home and Structural Remodeling
On older ranch homes and custom builds, whole-home work frequently includes moving walls, updating electrical panels, and correcting drainage that was never engineered for today’s rainfall expectations. This is where the San Martin context bites: open a wall on an old rural home and you may find framing or plumbing that triggers a county requirement. We scope for that up front, which is why our estimates reflect reality instead of a hopeful guess.
Licensed General Contractor in San Martin
A Licensed General Contractor in San Martin does more than coordinate subs. On unincorporated county land, that license carries the responsibility of pulling the right permits through Santa Clara County and scheduling inspections on the county’s timeline. Home additions in San Martin typically run $45,000 to $130,000, and garage conversions fall between $30,000 and $80,000. Those ranges assume access works, the septic or well clearance doesn’t add scope, and the grading plan is straightforward. When access is tight or the county flags a setback, we line-item the change before it becomes a surprise.
We also build ADUs in San Martin, working with modern prefab and modular manufacturers most general contractors can’t touch. An ADU on a San Martin lot typically runs $90,000 to $220,000 depending on utility connections, site work, and whether your lot can support the structure without major grading. Because many properties here are on private wells and septic, the utility piece is its own scope of work, and we don’t bury that cost.
Additions and ADU Work
A room addition in San Martin often means tying into an existing ranch footprint while keeping the rest of the house livable. We plan the sequencing around county inspections, not just trade availability. That’s the difference between a schedule that holds and one that slips after framing starts.
Garage and Accessory Conversions
Garage conversions are popular on San Martin acreage because the existing slab and roofline are already there. But when the conversion touches a bathroom or kitchen, county code changes the game: plumbing, septic load, and egress all come under review. We handle that paperwork and the build, so the conversion is legal and the inspection passes the first time.
Trusted Brands We Service in San Martin
Our San Martin customers expect materials that last through hot summers and winter rain without failing at year five. We work with more than 50 manufacturer brands across cabinetry, countertops, roofing, windows, doors, fencing, hardscaping, and plumbing fixtures, and we also handle Mr-Glass repair in San Martin. On the finish side, that includes Toto and American Standard plumbing, Schluter waterproofing, and Sterling bath systems, brands we install to manufacturer specification. Because we stock and source local parts for San Martin projects, we don’t wait on uncertain lead times when a fixture or component needs replacing mid-job. That keeps your remodel moving and your draw schedule aligned with actual progress.

AfterCommon General Contractor Problems We See in San Martin Homes
- County permit path surprises. A project that would sail through in Gilroy or Morgan Hill hits Santa Clara County review here, and any addition touching bedrooms, baths, or a kitchen can pull a septic or well setback question. If your contractor didn’t file for that clearance, the schedule stalls after framing starts.
- Rural access costs get underbid. Long private drives, orchard rows, and single-lane rural roads mean delivery trucks and equipment need staging space, not just a street address. A quote that ignores access doesn’t survive the first week of the job.
- Dust and drainage complaints. Graded lots throw dust in summer and runoff in winter. On unincorporated land, a county inspector will flag failed erosion control. Contractors who skip dust control and swale work create problems with the county and with neighbors.
- Constrained-site staging. Tight setbacks and shared drives mean materials can’t pile up wherever the truck drops them. If your contractor doesn’t plan material staging around the lot and the neighbor’s access, the site turns into a hazard and a liability.

FAQs About General Contractor in San Martin
Santa Clara County issues the building permit for any addition in San Martin, because the community is unincorporated and has no city building department. That means your contractor files through county planning and building, and any addition that touches bedrooms, baths, or a kitchen can trigger a septic clearance or well setback review before the permit gets approved. Call (833) 382-8544 and we’ll explain exactly what your specific scope will require from the county.
Site access changes your quote because delivery trucks, dumpsters, and equipment all need to reach the work area, and on a rural San Martin lot that isn’t automatic. A long private drive, a narrow orchard road, or a shared driveway can force material staging costs, smaller truck loads, and extra labor hours. We walk the access path before quoting, so the number we give you already accounts for how material actually arrives.
We keep the site clean with planned material staging on a gravel or hard surface, daily sweeping, and dust control on graded areas. We also respect county work hours and give notice before any work that touches a shared drive or property line. On a tight lot, being a good neighbor isn’t optional, it’s part of keeping the project on schedule.
A written scope lists every phase: demolition, rough-in, inspection points, insulation, drywall, finishes, and final walk. The draw schedule ties each payment to a specific milestone with inspection sign-off, so you release the next check when the county confirms the work is right. On a San Martin remodel with county oversight, that structure protects you from paying ahead of completed work. Call (833) 382-8544 and we’ll put a scope together for your project.
Yes. When a San Martin addition touches a bathroom, kitchen, or bedroom, the county typically requires septic clearance and well setback verification before the permit is final. We coordinate that directly with Santa Clara County and the septic and well professionals, so the clearance is documented before framing starts. That’s the difference between a permit that moves and one that stalls for months.
