Fast, Reliable General Contractor Across Belvedere
Hiring a general contractor in Belvedere means finding someone who understands that nearly every project here is a waterfront or hillside build with a permitting process unlike anywhere else in Marin County. We’re San Bruno Construction, led by Noel Carvalho, and we coordinate every phase of your remodel, addition, or ADU from the first demolition cut to the final design review sign-off. Call (866) 472-1908 to schedule a free estimate, and we’ll walk you through what your Belvedere home actually needs before you spend a dollar.
Why San Bruno Construction Is Belvedere’s Preferred General Contractor Company
Belvedere homeowners don’t hire a general contractor the way someone in a sprawling suburb does. You need someone who’s navigated the city’s design review board, knows what the planning department will flag on a slope-side lot, and plans around narrow roads where a dumpster and a delivery truck can’t both sit at the curb. Our team has managed remodels and rebuilds across Belvedere Island, from 1920s shingle-style homes near the lagoon to mid-century ranches up the hill, providing Belvedere KraftMaid service and more. We coordinate all licensed specialty trades under one contract, so the electrician, plumber, framer, and roofer answer to us, not to you. Noel Carvalho runs every project with a straight line of communication, no phone tag between three different vendors.
What clients in Belvedere tell us they appreciate most is the inspection-first approach. Before we bid, we open access panels, check crawlspaces, and document what’s behind the walls. That’s why our quotes hold up when other contractors’ change orders start piling up. We also carry access to 50+ vetted product brands, which matters in a town where the wrong window line or siding profile can get your design review application sent back for revisions. From ES Windows and ECO Window Systems to Mr-Glass glazing details that meet coastal wind requirements, we have the sourcing relationships to get Belvedere projects approved and built.
Styles & brands we work with







Residential General Contractor in Belvedere
A residential General Contractor in Belvedere does more than schedule trades. On this island, the job starts with understanding what the city will require before a single wall is opened. Belvedere’s design review board demands 3D-modeled submissions for even minor exterior changes, so our process budgets for that review timeline from day one. We handle the modeling, the submittal, the revisions, and the resubmission, so your draw schedule doesn’t stall at the wrong moment. Typical kitchen remodels in Belvedere run $14,000 to $45,000, bathrooms $9,000 to $28,000, and a home addition $45,000 to $130,000, depending on what’s behind your walls and what the hillside requires.
Pre-Construction Assessment and Design Review
Every Belvedere project starts with a site walk where we look for the things that only show up on this island: water intrusion at the foundation line from salt air and winter storms, timber retaining walls showing distress, and older redwood framing that has moved over 80-plus years. We document it, price it, and write it into the contract as a line item or a clearly defined allowance. Then we handle the 3D modeling and design review package, which is the single biggest scheduling factor on any Belvedere exterior or structural change.
Interior Remodeling on Belvedere Homes
When we do a kitchen or bathroom remodel in Belvedere, we’re often working inside a home built between 1910 and 1950. That means plaster walls, knob-and-tube wiring in some cases, and framing that doesn’t meet current shear or load standards. We inspect first, write allowances for what we expect, and document everything with photos before and after demo. You’ll know what a code upgrade costs before the inspector asks for it.
Hire a General Contractor in Belvedere
When you hire a General Contractor in Belvedere, you’re hiring someone to manage the parts of a remodel that most homeowners never see until it’s too late. The permit counter, the design review board, the geotech report on a hillside lot, the delivery schedule on roads where a 40-foot truck has to back down San Rafael Avenue. We handle all of it. A room addition in Belvedere typically runs $45,000 to $130,000, and that range reflects the difference between a straightforward second-story pop-out and a hillside foundation requiring piers, retaining, and drainage engineering.
Code Upgrades and Hidden Damage
Belvedere homes hide things. A 1920s shingle-style house on the island might have oversized redwood beams in fine shape, right next to a subfloor that has been quietly rotting from a failed waterproofing membrane for a decade. We open it up, we find out, and we write a change order that you approve in writing before we proceed. No surprise invoices after the fact.
Single-Contract Coordination
One contract, every trade. The cement contractor pouring a new retaining wall, the electrician rewiring the kitchen, the crew installing James Hardie siding that the design review board already signed off on. We coordinate the schedule and the accountability. When the inspector shows up, the right work is done in the right order.
Trusted Brands We Service in Belvedere
Belvedere homeowners care about products that survive salt air, fog, and winter storms without failing in five years. We spec and install lines from manufacturers built for coastal conditions. Window packages from ES Windows and ECO Window Systems hold up to marine air far better than standard builder-grade frames, and Mr-Glass glazing details are a regular part of our exterior upgrade packages. Because we have relationships across 50+ vetted product brands, you choose from real options in cabinetry, roofing, windows, and siding that meet both the design review board’s standards and your budget. We don’t push one brand. We give you three that will actually last in Belvedere.

AfterCommon General Contractor Problems We See in Belvedere Homes
- Failed waterproofing on hillside subfloors and decks. Salt air and winter rain in Belvedere corrode flashing and fasteners faster than most homeowners expect. We consistently find rot at the ledger board and under sliding doors on older lagoon-side homes.
- Knob-and-tube wiring behind original plaster. Many 1920s and 1930s Belvedere homes still have active knob-and-tube in walls that were never opened. Any remodel that exposes it triggers a full circuit upgrade, which we write into the contract as an allowance so the price doesn’t jump at inspection.
- Design review delays stalling the draw schedule. Belvedere’s 3D-modeled submittal requirement catches owners off guard. We budget the review window before we ever order materials, so you aren’t paying storage fees while a board meeting gets rescheduled.
- Failing timber retaining walls on steep lots. Heavy rains on Belvedere Island’s slopes push old timber walls to failure. We replace them with engineered block or concrete systems that the city will approve and that actually manage the water load.
Pricing for General Contractor in Belvedere, CA
Belvedere’s construction costs run higher than the Bay Area average because of the permitting process, hillside engineering, and the quality of materials the design review board expects. Here’s what we see in the current market:
| Project | Typical Range in Belvedere |
|---|---|
| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |
| Home Addition | $45,000 – $130,000 |
What moves these numbers beyond the usual factors is what we find once walls are open and what the city requires on your specific lot. A flat lagoon-adjacent property with recent electrical work will land at the lower end. A steep hillside with an aging retaining wall and a design review board that wants 3D models of every exterior change will push toward the higher end. We give line-item pricing after an inspection, and every allowance is defined in writing. Call (866) 472-1908 for a free estimate.

FAQs About General Contractor in Belvedere
We inspect before we bid, write specific allowances into the contract for the upgrades we’re likely to find, and any additional item gets priced and approved by you in writing before we do the work. On a 1920s shingle-style home on Belvedere Island, our crew opened a kitchen wall to find knob-and-tube wiring and undersized framing behind the plaster. We stopped work, wrote a change order for the electrical rough-in and a new load-bearing header, and had the owner’s written approval before the inspection sign-off. The project closed with a clean punch list and no surprise costs. Call (866) 472-1908 to talk through your specific house.
Yes, it does. Belvedere’s design review board requires 3D-modeled submissions for even minor exterior alterations, which is different from nearly every other city in Marin County. A small window replacement or siding change could sit in review for months. We prepare the 3D submittal package ourselves and coordinate the resubmission if the board requests revisions, so you aren’t stuck in limbo. Call (866) 472-1908 if you’re thinking about an exterior change and want to understand the timeline.
Expect plaster instead of drywall, redwood framing that may be undersized for current standards, and wiring or plumbing that hasn’t been touched since the Eisenhower administration in some cases. Our pre-bid inspection identifies most of it. What we can’t see until demo, we handle with clearly defined allowances and written change orders. You won’t get an invoice for something we haven’t shown you first. Call (866) 472-1908 for a free estimate that accounts for your home’s age and condition.
We plan the delivery schedule around Belvedere’s road constraints before the project starts. That means coordinating dumpster placement, material drops, and trade parking so we’re not blocking a lane or fighting a delivery truck for space on a hillside street. We’ve done it enough times on Belvedere Island to know which corners a 40-foot truck can and can’t make. Call (866) 472-1908 and we’ll walk your specific street before we ever submit a bid.
Yes. Retaining wall replacement on Belvedere’s hillsides is often part of a larger addition or remodel, and we handle it under the same contract. We bring in a geotechnical engineer when the slope requires it, design a wall that will pass city review, and coordinate the excavation and drainage. The design review board will want to see the full package before approving, and we manage that process for you. Call (866) 472-1908 for a free estimate on the whole scope, wall included.
