Fast, Reliable General Contractor Across San Martin
Finding a general contractor in San Martin who actually understands how this unincorporated corner of Santa Clara County works is harder than it should be. We’re Milpitas Construction, led by Ken Stafford, and we’ve built a practice around exactly what San Martin homeowners and ranch owners need: a single company that handles the permit path, the long-lead materials, and every trade in between. If you’re planning a custom home, an addition, a shop, or a high-end remodel on a multi-acre parcel, call us at (877) 752-4194. We’ll walk the property with you, look at what the county will require, and give you a written scope and price before anything gets ordered.
Why Milpitas Construction Is San Martin’s Preferred General Contractor Company
San Martin projects don’t look like Silicon Valley projects. The parcels are bigger, the utilities are often private, and the building department is a county office, not a city counter. Our General Contractor team knows that reality because we work it regularly. We’ve pulled Santa Clara County permits for additions, ag buildings, shops, and custom homes throughout the 95046 ZIP code, and we know which scopes trigger a land-use review and which ones don’t.
Ken Stafford set this company up around a simple idea: one accountable partner who names the brands, fixes the price in writing, and runs the schedule on the long-lead items, not the labor. That’s why San Martin clients keep calling us back after the first project. We don’t hand you off to a rotating set of subs who’ve never seen your parcel. We run the job, and you deal with us.
Response time to San Martin is straightforward. We schedule site walks in and around San Martin every week, and we’ll typically get boots on your property within a few business days of your call. For kitchen and bathroom projects, we bring samples with us, not a vague promise to send a catalog later.
Styles & brands we work with
General Contractor Services in San Martin
General Contractor Services in San Martin cover everything from a full custom home on former orchard land to a kitchen remodel in a 1970s ranch house on a well and septic system. The work here tends to be high-end and architect- or designer-driven, which means the schedule is ruled by millwork lead times, specialty glass deliveries, and county review calendars, not by how many carpenters we can put on site. A full custom build or major remodel in San Martin typically runs well into six figures when you’re working with custom cabinetry, architectural glass, and premium finishes. We fix the scope and allowances in writing before a single cabinet or window is ordered.
Custom Homes and Additions
Building on multi-acre parcels in San Martin almost always starts with site evaluation, especially when the property is on well and septic. We coordinate the county permit path, the utility evaluation, and then the build itself, including structural work that has to be sequenced around the summer dry season when concrete pours and exterior framing go fastest.
High-End Kitchen and Bath Remodeling
San Martin kitchens lean custom, with homeowners choosing directly from brands like Wellborn cabinetry and Cambria countertops rather than big-box off-the-shelf lines. We spec materials by name, order them on a fixed allowance, and schedule rough-in and subfloor work so nothing sits idle waiting on a delivery.

Construction Company in San Martin
As a Construction Company serving San Martin, we handle the full exterior-to-interior scope that most firms split across two or three different contractors. That matters here because so many San Martin properties have ranch outbuildings, shops, barns, and light-ag structures that need the same level of coordination as the house. A home addition in San Martin runs $45,000 – $130,000 depending on scope, foundation work, and finish level. An ADU typically lands between $90,000 and $220,000, and a garage conversion runs $30,000 – $80,000.
Shops, Barns, and Agricultural Structures
San Martin has no city hall, so these scopes route through Santa Clara County’s building department and often a county land-use review. We front-load that paperwork because it is always the first calendar item, whether you’re adding a shop, replacing a barn, or building a winery outbuilding on a multi-acre parcel.
Prefab and ADU Construction
We work with modern prefab manufacturers like Abodu, Dvele, Mighty Buildings, Boxabl, and Plant Prefab. For San Martin homeowners who want an ADU without a 14-month stick-built schedule, prefab plus our site and utility work is a legitimate path, and it’s one most traditional GCs cannot credibly offer.
Trusted Brands We Service in San Martin
We don’t ask San Martin homeowners to guess which products hold up. Our active access to more than 50 brand-name product lines means you choose from proven contractor-grade tiers across every major category: cabinetry, countertops, plumbing fixtures, roofing, windows, doors, siding, fencing, hardscaping, and more. In San Martin, we regularly spec Belgard pavers for driveways and patios because they hold up through the hot, dry summers and the winter wet season that hits the south county foothills. We also work frequently with Jerith aluminum fencing for rural property lines and ActiveYards for ranch-style enclosures. Premium brands, proper installation, one accountable team.

AfterCommon General Contractor Problems We See in San Martin Homes
- Custom millwork ordered before the scope is locked. We see this constantly: a homeowner or a well-meaning designer orders custom cabinetry or specialty glass, then changes the ceiling height or the island layout, and the change order eats the contingency. We fix allowances in writing first.
- Treating the county permit as an afterthought. On a shop or barn addition in unincorporated San Martin, the Santa Clara County land-use review can push a start date by weeks or months. Front-loading that paperwork is not optional here.
- Skipping the well and septic evaluation. Many older San Martin structures sit on private wells and septic systems. Adding a bathroom or expanding the footprint can trigger system capacity requirements, and that discovery needs to happen before foundation design, not after.
- Summer dry-season conflicts with concrete and exterior work. San Martin gets hotter inland summer highs than the coastal Bay cities. Pouring concrete or installing roofing during peak heat windows narrows the workable hours, and scheduling around that matters for both quality and timeline.
Pricing for General Contractor in San Martin, CA
San Martin pricing is not a mystery, but it is different from Morgan Hill or Gilroy because the county permit path and the long-lead materials drive more of the cost than labor rates do. Here are our current market-calibrated ranges for the work we do most often in 95046:
| Project | San Martin Price Range |
|---|---|
| Kitchen Remodel | $14,000 – $45,000 |
| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |
| Cabinet Installation | $4,000 – $13,000 |
| Countertop Installation | $2,000 – $6,500 |
What moves the number most on a San Martin job is the finish tier and the lead time on the materials you choose. A stock door and a set of KraftMaid cabinets land on the low end of a kitchen remodel. Wellborn cabinetry and Cambria surfaces with architectural glass push you toward the upper end. We price by named product, never by a vague allowance that drifts later. Call (877) 752-4194 for a free estimate with a written line-item price before anything gets ordered.

FAQs About General Contractor in San Martin
Because San Martin is unincorporated Santa Clara County territory, there is no city hall to pull permits from. Every addition, shop, ag building, or structural change routes through Santa Clara County’s building department, and depending on the parcel and the scope, the county may also require a land-use review before the building permit is issued. We handle that path from day one because it is the first calendar item on nearly every San Martin project. Call (877) 752-4194 and we’ll tell you what your specific parcel will trigger.
Millwork lead times and specialty glass deliveries set the schedule, not labor. A Wellborn cabinetry order can run 10 to 16 weeks, and full-height architectural glass has its own manufacturing queue. We sequence rough-in, subfloor, and structural work ahead of those deliveries so crews aren’t standing idle, and we lock the scope before ordering so a late design change doesn’t restart the clock. For an exact timeline on your project, call (877) 752-4194.
Yes. On any parcel outside the municipal sewer and water districts, we evaluate the well and septic system before foundation or structural design is finalized. Adding a bathroom, expanding the footprint, or building a shop with plumbing can trigger system capacity requirements that change the rough-in plan entirely. Skipping that evaluation is how projects stall at inspection. Call (877) 752-4194 to schedule a site walk.
San Martin’s inland south county location means hotter summer highs than the coastal Bay cities and a pronounced dry season that stretches well into fall. Concrete pours cure differently in sustained heat, and exterior framing and roofing work has to be sequenced around peak afternoon temperatures. We schedule pours and exterior phases for morning windows when possible and build that expectation into the calendar up front.
We fix the scope of work and the allowances in writing before a single cabinet, window, or specialty glass panel is ordered. That means the kitchen layout, the ceiling heights, the plumbing fixture lines, and the finish tiers are named and priced up front. If you or your designer change something later, the cost of that change is a written line item, not a surprise buried in the next draw. Call (877) 752-4194 and we’ll show you what a fixed-scope bid looks like.
