Fast, Reliable General Contractor Across Millbrae
Finding a General Contractor in Millbrae who understands the city’s permitting culture is harder than it should be. We get it. Millbrae’s design-review process is strict for a city this size, and a second-story addition on a hillside lot off Helen Drive hits different requirements than one in Burlingame. Timberline Contractors handles the whole scope, from geotechnical reports to final inspection sign-off, so you’re not stuck coordinating three separate specialists. Call (866) 253-5808 to talk through your project and get a free estimate.
Why Timberline Contractors Is Millbrae’s Preferred General Contractor Company
Millbrae homeowners call us because we’ve already navigated the city’s plan-check sequence on dozens of projects. We know which hillside lots trigger a geotechnical report, which second-story additions need a wind-load calc, and when design review will slow a permit down. That local knowledge keeps your project moving when a contractor from outside the area would still be figuring out where to file.
Nelson Fung runs every Millbrae job personally. He’s the person who walks your lot, reviews the structural drawings, and stands next to the inspector when the shear-wall nailing gets signed off. That matters in a city where closing up a wall before inspection can mean tearing it back open.
We bring 50-plus brand partners to every Millbrae project. Cambria quartz, GAF roofing, James Hardie siding, Therma-Tru entry doors, Kohler fixtures. One contractor, every phase. From the foundation to the ridge cap.

General Contractor Services in Millbrae
General Contractor Services in Millbrae cover everything from whole-house remodels on 1940s bungalows to second-story additions on hillside lots near the western slope. A typical kitchen remodel here runs $14,000 – $45,000, a bathroom remodel $9,000 – $28,000, and a full home addition $45,000 – $130,000. Millbrae’s housing stock, mostly 1940s – 1960s single-family homes, means we’re usually working around original framing and outdated electrical rather than clean new construction.
Hillside Additions and Seismic Retrofits
Western Millbrae lots often need pier foundations and geotechnical reports before the city will even look at a structural drawing. We handle that paperwork as part of the contract. The goal is a permit that clears plan check without months of back-and-forth.
Whole-House Remodel for 1940s – 1960s Homes
Older Millbrae homes hide surprises: knob-and-tube wiring, undersized headers, foundation cracks from decades of settling. We open walls with the plan already in place for what we’ll find. The quote accounts for the age of the house, not just the finish materials.

Construction Company in Millbrae
As a Construction Company working in Millbrae, we take on scopes that most remodelers won’t touch: full exterior envelope work, foundation repair, roof replacement, and ADU construction. An ADU in Millbrae runs $90,000 – $220,000, a garage conversion $30,000 – $80,000. Those numbers include the design-review fee, structural engineering, and the inspection sequence the city requires.
Exterior Envelope and Roofing
Millbrae’s marine air and occasional heavy rain mean flashing and waterproofing have to be done right. We install GAF and CertainTeed roofing systems with the underlayment and edge details that hold up to fog moisture. A roof replacement in Millbrae runs $8,000 – $20,000.
ADU and Garage Conversion Builds
Flat-lot Millbrae homes near the BART station often hit lot-coverage limits fast. An ADU above a garage or a converted garage becomes the practical path to extra square footage. We work with prefab partners like Abodu and Dvele when the site fits, and stick-build when it doesn’t.
Trusted Brands We Service in Millbrae
We stock and install product lines that hold up to Millbrae’s fog and moisture: Blanco sinks and Delta faucets in kitchens, American Standard and Toto fixtures in baths. The showroom comes to the project. You pick finishes at your dining table, not in a catalog. For Millbrae’s 94030 zip code, we keep lead times short on the brands most homeowners here choose.

AfterCommon General Contractor Problems We See in Millbrae Homes
- Design review skipped early. A homeowner hires a contractor, drawings get submitted, and only then does anyone mention Millbrae’s design review step. The permit sits in plan check for three months while the draw schedule collapses. We file design review before structural drawings, and the sequence holds.
- Hillside quotes without geotech. A second-story addition quoted at $60,000 without a geotechnical report is a fiction on the western slope. Pier foundations and hillside anchoring add real cost. Our quotes for hillside work include those line items up front.
- Shear walls closed before inspection. Millbrae inspectors sign off on shear-wall nailing and roof sheathing at specific stages. Closing up early means destructive rework, and the missing documentation can show up later when an insurer reviews the policy. We schedule inspections before the drywall goes up, every time.
- Flat-lot additions that hit coverage limits. Homeowners on flatter Millbrae streets often plan a first-floor bump-out, then find out the lot-coverage limit blocks it. Going up is usually the answer. We run the coverage math before the design gets locked.

What moves the number? Hillside geotech and pier foundations, design-review iterations, and whether the existing structure needs seismic retrofitting before you can build up. A cheap bid that skips the geotech line item or the wind-load calc will come back to you as a change order. Ours won’t. Call (866) 253-5808 for a written, line-item estimate.

FAQs About General Contractor in Millbrae
A second-story addition on a Millbrae hillside typically needs to meet an Exposure C wind-load rating and current seismic shear requirements, which usually triggers a structural peer review. Our team runs the calc, submits it with the permit package, and documents the inspection sign-off.
Yes. Millbrae’s design review applies to most exterior changes and additions, and it’s stricter than what Burlingame or San Bruno require on similar scopes. We file design review first, before structural drawings, so the permit doesn’t stall in plan check.
When the city signs off on shear-wall nailing, roof sheathing, and final inspection, you get written documentation. That becomes the file your insurer reviews after a claim, and it can affect your premium. On a hillside rebuild off Helen Drive, the third-party inspection sign-off was the key document when the owner’s insurer re-rated the policy after completion.
A compliant quote includes the geotechnical report if the lot slopes, the design-review fee, the wind-load calc, the pier foundation line items, and scheduled inspection points. Cheap bids skip those and hit you with change orders later. Call (866) 253-5808 for an estimate that’s built like the house should be.
Flat-lot Millbrae homes near the BART station often hit lot-coverage limits quickly, which means the city won’t approve a first-floor bump-out but will approve going up. We run the coverage math before the design gets locked, so you know your options on day one. Call (866) 253-5808 and we’ll walk your lot with you.
