We know those differences because we’ve worked them. Milpitas Construction serves all of the 94965 zip code with full-scope remodeling, renovation, and ADU construction. If you’re planning a kitchen remodel, bathroom renovation, or home addition in Marin City, call (877) 752-4194 for a free estimate.

Why Milpitas Construction Is Marin City’s Preferred General Contractor Company
Marin City homeowners call us because we show up knowing what we’re looking at. The housing stock here is not like Mill Valley or Corte Madera. It’s mid-century war-worker housing, small stucco and wood-frame homes on sloping lots, with the original framing and wiring still behind the walls in many cases. We quote accordingly, which means our numbers hold. Nothing dissolves trust faster than a contractor who quotes a generic number, then acts surprised when the wall comes open.
Our General Contractor team has managed remodels throughout Marin City, from the flats near Drake Avenue up into the hillside parcels off Cole Drive. We’re familiar with the Marin County permitting path and the jurisdictional quirks that come with being an unincorporated island surrounded by Sausalito. That familiarity keeps your project moving.
Response time to Marin City is straightforward: we schedule a site visit within a few days of your call, walk the property with you, and deliver a written line-item quote. No vague ballparks. Ken Stafford personally reviews every estimate before it goes out.
Styles & brands we work with







Construction Company in Marin City
Construction Company work in Marin City typically means opening up walls, repairing or replacing what’s failing, and bringing the structure up to current code before any finish work begins. A typical budget for this scope runs $14,000 to $45,000 for a kitchen remodel, $9,000 to $28,000 for a bathroom, and $45,000 to $130,000 for a home addition, depending on what the demo reveals. Because most homes here were built in the 1940s and 1950s, the first week of construction is often the most important.
Opening Walls and What We Find
Older Marin City homes hide things: cloth-wrapped wiring, undersized headers, rot from decades of fog-driven moisture. We inspect first, document everything with photos, and price any required upgrades as written change orders before we touch them. You approve the number, we do the work. No surprises because the surprise is already in the estimate.
Permitting Reality for Unincorporated Properties
Marin City is an unincorporated county island surrounded by Sausalito. That means a job on the flats often falls under Marin County, while hillside parcels off Cole Drive and Drake Avenue can trigger Sausalito-adjacent review. Misreading that line stalls a project before demolition even starts. We confirm jurisdiction before filing anything.
Remodeling Contractor in Marin City
Remodeling Contractor work in Marin City means managing the full scope from demo to final inspection under one contract, with one point of contact. Kitchen and bathroom remodels are the two most common projects we handle here, along with room additions and garage conversions. A kitchen remodel runs $14,000 to $45,000. A bathroom remodel runs $9,000 to $28,000. A garage conversion runs $30,000 to $80,000.
The Allowance Approach
We write allowances into every Marin City remodel contract for the things we can’t see until walls are open: wiring, framing, subfloor repair. That’s not a way to inflate the price. It’s how an honest contractor quotes a mid-century home without guessing. When we open the wall and find cloth-wrapped wiring or a notched header, the allowance covers it, and we price it in writing before proceeding.
Moisture-Resistant Detailing
The foggy, marine-influenced microclimate off Richardson Bay keeps exterior walls damp for much of the year. On a remodel, that means we specify moisture-resistant drywall in kitchens and baths, check subfloor condition around sinks and tubs, and verify that exterior flashing and drainage are actually doing their job. Skipping this step is how rot callbacks happen after the punch list is signed.
Trusted Brands We Service in Marin City
We spec materials by name, so you know exactly what’s going into your home. For Marin City remodels, that means options like Cambria and Caesarstone countertops, KraftMaid and Wellborn cabinetry, Kohler and Grohe fixtures, and James Hardie siding. We also work with premium window lines including ECO Window Systems, CWS, and ES Windows when a project calls for new or replacement glazing. Our access to 50+ brand-name product lines means we’re not limited to whatever the local big-box store stocks. We order what your project actually needs, and we handle lead times and delivery.

AfterCommon General Contractor Problems We See in Marin City Homes
- Wrong-jurisdiction filings. Homeowners and even some contractors assume a Marin City address means Sausalito permits. It often doesn’t. We verify county versus Sausalito-adjacent jurisdiction before paying any filing fee, because a rejected permit can add weeks to a project.
- Hidden wiring and framing behind original plaster. Mid-century war-worker housing here almost always hides outdated wiring and undersized framing. A quote without allowances for these discoveries will move once the wall comes open. Ours doesn’t.
- Moisture and rot from the Richardson Bay microclimate. The fog keeps exterior wood damp. Exterior walls, window sills, and subfloors near plumbing all need inspection for rot before finish work begins.
- Storm runoff on hillside lots. Parcels off Cole Drive and Drake Avenue collect runoff that funnels down toward the flats during winter rains. Drainage and erosion control need to be part of the scope on hillside projects, not an afterthought.

FAQs About General Contractor in Marin City
We stop, document it, and price the fix as a written change order with a fixed number and a revised draw schedule before we touch anything. On a 1940s stucco home off Cole Drive, our crew opened a kitchen wall to find cloth-wrapped wiring and a load-bearing header that had been notched down to bare minimum. The county inspector flagged both during rough-in. We wrote the wiring upgrade and a sistered header as a change order, got your approval in writing, then used moisture-resistant drywall and a Kohler rough-in valve to address the marine damp that had already rotted the subfloor near the sink. That’s how we handle discoveries in Marin City: inspection first, written approval second, work third. Call (877) 752-4194 to talk through your project.
We confirm jurisdiction before filing anything. Marin City is an unincorporated county island, which means jobs on the flats often fall under Marin County while hillside parcels off Cole Drive and Drake Avenue can trigger Sausalito-adjacent review. We’ve seen projects stall for weeks because someone filed with the wrong agency. Our process: verify the parcel’s jurisdiction, file with the correct authority, and track the review through sign-off. That’s not a formality. It’s the difference between demolition and a dead-stop delay.
Because mid-century war-worker housing here almost always hides outdated wiring, undersized framing, or rot behind original plaster, and no contractor can see those conditions before the wall is open. A fixed price without allowances is a guess. Our allowances cover what we expect to find, based on the housing stock in Marin City and properties we’ve already worked on in the 94965 zip code. When we open the wall, the allowance is there. If we don’t use it, it comes off the contract. Call (877) 752-4194 for a quote that includes these allowances up front.
We plan for year-round damp from the Richardson Bay fog, which keeps exterior wood wet for months at a time. That means specifying moisture-resistant materials, checking flashing and drainage on every penetration, and inspecting subfloor and sill plate condition before we commit to finish work. On hillside lots, we also account for winter storm runoff that funnels down toward the flats. Skipping moisture detailing is how you get rot callbacks after the job is signed off. We build the detailing into the scope from day one.
Frequently, yes. Once walls are open, county inspectors require current-code wiring, plumbing, and structural standards, which means a 1940s home with original electrical will often need at least partial rewiring and possibly framing corrections before rough-in can pass. We budget for those upgrades in the allowances we write into your contract, so they don’t blind-side you mid-project. A kitchen remodel in Marin City runs $14,000 to $45,000, and part of that range reflects the code-upgrade reality of the local housing stock. Call (877) 752-4194 for an estimate that accounts for all of it.
