Fast, Reliable General Contractor Across Tiburon
Hiring a General Contractor in Tiburon means finding someone who understands that almost every job here involves a steep slope, a protected view, or a foundation that’s been holding a hillside together since the 1920s. We’re Milpitas Construction, and we’ve worked on enough Tiburon Peninsula homes to know the drill before we open the first wall. Our crews respond to Tiburon projects across 94920 with a plan for material access, permitting, and the surprises older homes tend to hide. If you’re planning a remodel, addition, or ADU in Tiburon, call us at (877) 752-4194 for a free estimate.
Why Milpitas Construction Is Tiburon’s Preferred General Contractor Company
Homeowners in Tiburon don’t hire a contractor to manage a spreadsheet of subcontractors. They hire someone who can walk a hillside lot in Old Tiburon and already know what the town’s design review board will ask about before the drawings are even submitted. That’s the kind of local knowledge we bring to every Tiburon project. Our reputation in Tiburon and Belvedere comes from finishing remodels and additions on lots where other contractors stumble, specifically on material access and entitlement timelines. We quote inspection-first because we know what’s behind the walls of a 1930s waterfront cottage or a 1960s view home that’s been expanded twice already. You’ll talk to one accountable team from rough framing to final paint, and you’ll get a written line-item quote rather than a handshake and a guess. Call (877) 752-4194 and we’ll take a look at your Tiburon project without obligation.
Styles & brands we work with







General Contractor Services in Tiburon
General Contractor Services in Tiburon start with a simple question that most firms skip: what will we find once the walls come down? Opening an older peninsula home typically turns up cloth wiring, undersized or sistered framing, failed waterproofing at deck transitions, and the code upgrades a permit triggers once work is exposed. We handle it by doing a framing and rough-in inspection early, writing allowances into the contract for exactly these discoveries, and pricing any surprise as a written change order before another board comes out. You’ll never get a quote that assumes the inside of your walls looks like new construction.
Remodels and Additions on Tiburon Slopes
Remodels and additions dominate Tiburon work because the peninsula is nearly fully built out. A kitchen remodel in Tiburon runs $14,000 to $45,000 depending on whether we’re doing a cabinet and counter refresh or moving walls and upgrading electrical. Home additions run $45,000 to $130,000, and on hillside lots that number almost always includes pier or grade-beam work and some kind of retaining structure. We spec materials by name so you know exactly what’s going into your home.

ADU and Prefab Construction in 94920
Tiburon homeowners looking at ADU construction face tighter lot constraints than almost any Marin town. ADU Construction in Tiburon runs $90,000 to $220,000, with prefab options from manufacturers like Abodu and Dvele shifting the cost and timeline in ways a traditional build can’t. That range accounts for foundation work on slopes, utility connections, and the Town of Tiburon’s accessory structure review. We manage the ADU from entitlement through final inspection under one contract, one point of contact.

Construction Company in Tiburon
As a Construction Company serving Tiburon, we’ve learned that the job doesn’t start with a hammer. It starts with an honest walk-through of what the lot will demand. Tiburon and Belvedere hillside streets routinely have no driveway access, so materials get walked in by hand or craned over the house. That access line item can rival the framing budget on a steep lot, and we plan it from day one instead of discovering it at the first delivery.
Full Exterior and Structural Scope
Roof replacement in Tiburon runs $8,000 to $20,000, and the salt air off Richardson Bay means we pay close attention to fastener and flashing spec. Window replacement runs $4,500 to $15,000, and on view-facing elevations, the glass package matters for both the building envelope and the view-protection discussion that comes with any exterior change. Siding, deck construction, fencing, and hardscaping all fall under our single contract, so the same team managing your roof knows what the kitchen remodel underneath it will need.
One Team From Permits to Punch List
The Town of Tiburon’s design review and coastal-adjacent review processes can stretch timelines before framing starts, and Belvedere’s hillside and waterfront oversight is even stricter. We handle that entitlement phase as part of the build, not as a separate headache for you to chase. Permits get pulled, inspections get scheduled, and the draw schedule gets built around the actual review timeline. You get one accountable partner from the first drawing to the final written punch list.
Trusted Brands We Service in Tiburon
We’re one of the few general contractors with active access to more than 50 brand-name product lines across every major trade, and Tiburon homeowners can touch and choose from proven contractor-grade tiers rather than navigating a big-box aisle alone. For windows and doors on view-facing elevations, we work with ECO Window Systems, ES Windows, and CWS to get the glazing, air infiltration, and corrosion resistance that coastal exposure demands. For cabinetry, we specify KraftMaid and Wellborn; for countertops, Cambria, Silestone, and Caesarstone; for roofing, GAF and CertainTeed. We keep material leads tight for Tiburon customers so nobody waits two weeks on a glass package that was ordered wrong the first time.

AfterCommon General Contractor Problems We See in Tiburon Homes
- Cloth wiring and undersized load-bearing framing hidden behind finished walls. A 1920s waterfront cottage in Old Tiburon looks clean until the drywall comes off. We price inspection-first so the quote reflects what’s actually behind the wall, not what the last remodel left covered.
- Failed waterproofing at deck transitions and window rough openings. Salt air and wind off Richardson Bay rot deck flashing and window sills faster than inland Marin. We reflash and reseal every exterior opening we touch, not just the one that leaked.
- Pier-and-grade foundations on clay slopes that move with seasonal rain. The foggy marine layer and winter rains saturate Tiburon’s clay soils and create drainage and slope-stability issues. Foundation and retaining work is often the first real cost on a hillside addition.
- No driveway access on steep Belvedere and Tiburon streets. Materials get walked up or craned over the roof, and that haul is a budget line item, not a surprise. On a hillside cottage in Old Tiburon, our crew opened the subfloor during a kitchen addition and found joists sistered to undersized, salt-corroded framing over a pier-and-grade foundation, plus cloth wiring and no waterproofing at the old deck transition. We paused, brought in the town inspector for a rough-in and framing inspection sign-off, and priced the reframing, rewiring, and flashing as a written change order with allowance adjustments before touching another board. Materials came up the slope by hand and crane because there was no street access, and the project closed out on a written punch list.
Pricing for General Contractor in Tiburon, CA
Tiburon pricing reflects the lot, the age of the house, and what’s behind the walls, not just the visible finishes. A kitchen remodel in Tiburon runs $14,000 to $45,000.

A home addition runs $45,000 to $130,000, and an ADU runs $90,000 to $220,000. These are honest ranges, and the biggest variable is hidden framing, wiring, and waterproofing that a fixed price off the visible finishes won’t catch. We quote inspection-first, write allowances into the contract, and price every surprise as a written change order so you approve it before we touch it. Call (877) 752-4194 for a free estimate with a line-item scope for your Tiburon project.

FAQs About General Contractor in Tiburon
We expect to find it, especially in the early-1900s waterfront cottages and mid-century view homes common across 94920. Our contract includes written allowances for cloth wiring, undersized or sistered framing, failed waterproofing, and the code upgrades a permit triggers once walls are open. We bring in the town inspector for a rough-in and framing sign-off before any hidden condition gets torn out, and every surprise is priced as a written change order with allowance adjustments. You approve the number before another board comes down. Call (877) 752-4194 to walk through what your Tiburon home is likely to turn up.
Because nearly every buildable lot on the Tiburon Peninsula sits on a slope with clay soils, a pier-and-grade foundation, and neighbors’ protected coastal views below you. Drainage and slope stability are governed by the Town of Tiburon’s design review and Belvedere’s even stricter hillside and waterfront oversight. A second-story addition on a steep lot commonly triggers a geotechnical report and some kind of retaining structure before framing can start. That entitlement and engineering work is as central to the estimate as the framing itself.
We plan the haul as a line item from the first walk-through. On Tiburon and Belvedere hillside streets, materials often get walked in by hand or craned over the house because there’s no driveway. That access work can be a bigger number than the framing budget, and it affects the schedule and the neighbors’ views. We schedule the crane or the walk-up crew before demo starts, not after the subfloor is open. This is one reason our Tiburon quotes always include an access plan.
Yes, it can, and we treat that review as part of the project rather than a surprise. The Town of Tiburon’s design review and coastal-adjacent processes protect neighbors’ and coastal views, and a second-story addition on a hillside lot is exactly the kind of change that draws attention before framing begins. We work with the town and your neighbors early, adjust the massing and glass placement to respect the view corridor, and build the entitlement timeline into the draw schedule. That keeps the project moving instead of stalling mid-design. Call (877) 752-4194 to talk through your addition’s review risk.
An allowance is a written dollar amount in the contract set aside for conditions we can’t see until walls are open, such as deteriorated framing, cloth wiring, or failed flashing at a deck transition. When we open up that area, we show you what we found, get a price from the trade, and issue a written change order that adds or subtracts against the allowance. You approve it before we proceed. No allowance means the contractor either eats the cost, skips the fix, or hands you a surprise bill. We don’t play any of those games on Tiburon jobs. Call (877) 752-4194 for a quote with allowances written in from the start.
