General Contractor in San Francisco — Licensed & Insured, Written Fixed-Price Quotes

Fast, Reliable General Contractor Across San Francisco

Hiring a general contractor in San Francisco means hiring someone who understands that salt air, fog, and pre-1940 wood framing decide more about your remodel than any design magazine does. Copperleaf Contractors has built our reputation across 94111, 94112, 94114, and 94115 on exactly that: specifying materials that survive the marine layer, managing the permit-heavy culture at the Department of Building Inspection, and running interior and exterior scopes under one crew so you don’t juggle five vendors. Call (833) 589-8173 for a free estimate, and we’ll walk your property with the same eye we bring to every Victorian, Edwardian, and mid-century build in the city.

Why Copperleaf Contractors Is San Francisco’s Preferred General Contractor Company

Noel Cavanaugh leads our team with a simple rule: the material decides the outcome, not the labor line. That’s why we stock local parts for San Francisco customers through 50-plus vetted manufacturer brands, including Dvele and Plant Prefab for ADU and prefab work. When a homeowner in the Mission asks about a kitchen remodel, we talk Cambria and Silestone before we talk demo dates. When a Noe Valley client wants new windows, we spec PGT or CGI frames with marine-grade fasteners, because standard electro-galvanized hardware fails early in the fog belt. That specificity is why San Francisco homeowners keep calling us back for the next phase.

Our response time to San Francisco neighborhoods runs tight because our base in Pacifica sits minutes from the city. A project walk in Visitacion Valley or the Haight happens on your schedule, not some corporate dispatch board. We pull permits, write line-item allowances in writing, and manage every trade from foundation to roofline. One contractor, every trade, and a paper trail that survives resale.

Residential General Contractor in San Francisco

Residential General Contractor work in San Francisco almost always starts with the building envelope: roof, siding, windows, and the structural bones holding them. In a city where marine fog and steady onshore moisture keep exterior surfaces damp for months, the roofing fasteners, window frames, and joint sealants you choose matter more than the paint color. A roof replacement in San Francisco runs $9,440 – $23,600. Window replacement runs $5,310 – $17,700. Those are coastal-spec numbers, and they include hardware that won’t rust through before the next decade ends.

Full-Envelope Scope, Single Contract

We run roofing, James Hardie siding, PGT and Therma-Tru windows, and hardscape under one project team. No coordinating three separate bids or finger-pointing when the flashing meets the siding. Your remodel, your material choices, and one point of accountability through the final inspection.

Interior Work Built to the Brand Standard

A partial bath remodel in a 1912 Edwardian is not a quick weekend job. We open walls and find lath-and-plaster, balloon framing, and sometimes decades of un-permitted patchwork. Our Schluter-system tile prep and Kohler, Moen, or Toto fixture installs are built to the manufacturer’s specification, because the warranty only matters if the substrate is done right first.

Hire a General Contractor in San Francisco

Hire a General Contractor in San Francisco when the scope touches structure, envelope, or any system the city will inspect. That includes soft-story retrofit triggers, ground-floor garage conversions, and any project where the Department of Building Inspection wants stamped drawings. A garage conversion in 94112 or 94114 typically runs $35,400 – $94,400. A home addition runs $53,100 – $153,400. The range reflects seismic scope, foundation work, and finish level, not markup games.

Seismic Compliance Without Schedule Blowup

Our team knows the Soft Story Retrofit Ordinance inside out. When a ground-floor permit pull drags the whole building into mandatory shear upgrade scope, we scope it clearly, price it in writing, and sequence inspections so your draw schedule stays honest.

Prefab and ADU Capability

Through partnerships with Dvele, Plant Prefab, Abodu, and Mighty Buildings, we can deliver an ADU on a San Francisco lot where site access, setback rules, and soil conditions make stick-built construction slow. ADU construction in San Francisco runs $106,200 – $259,600, depending on system, foundation, and utility work.

Trusted Brands We Service in San Francisco

We don’t push a single house brand. Homeowners in San Francisco choose from competing manufacturers per category: Cambria, Silestone, or Caesarstone for countertops; Kohler, Moen, Toto, or Grohe for fixtures; GAF, CertainTeed, or Owens Corning for roofing; Belgard, Unilock, or Techo-Bloc for hardscape. Our team stocks common replacement parts and hardware for these brands locally, which means faster turnaround when an inspection correction or material swap pops up mid-project. For ADU and prefab builds, we bring Dvele, Plant Prefab, and Mighty Buildings to the table. Choose the material, not the markup.

Common General Contractor Problems We See in San Francisco Homes

• Rusted electro-galvanized fasteners on exterior work. San Francisco’s bay salt air eats standard hardware in under a decade. We spec hot-dip galvanized or stainless fasteners on every exterior envelope scope, which typically adds a small percentage to the bid but avoids a full refasten within ten years.
• Balloon framing with no shear panels. On a Victorian in the Mission, our crew opened a ground-floor garage wall and found original redwood balloon framing with no shear panels and a row of rusted-through galvanized nails where the salt air had been working for decades. We scoped the soft-story retrofit with a load-bearing shear upgrade, switched the exterior hardware to stainless and hot-dip fasteners, and wrote every allowance and change order in writing before the rough-in inspection sign-off.
• Untreated fence posts and unsealed paver joints on fog-belt lots. The damp never really leaves. We specify treated posts and sealed joints on every exterior build west of Twin Peaks and bay-adjacent block, because the inland-spec version fails early.
• Hidden un-permitted remodel layers. We routinely find previous work with no permit record when opening walls in the Mission, Chinatown, and Visitacion Valley. That’s not a reason to panic; it’s a reason to budget for a correction line and pull the right permits before we touch anything structural.
