Fast, Reliable General Contractor Across San Francisco
A general contractor in San Francisco has to understand that the city builds differently than anywhere else. Tight lots, steep hills, historic row houses, and a building code written for density and seismic survival shape every remodel, addition, and roof replacement we take on. Iron Beam Contractors runs projects across the city with one accountable team, from the first structural question to the final inspection sign-off. If you’re planning a kitchen remodel in the Mission, a garage conversion in Noe Valley, or a full home addition on a Bernal Heights hillside, call us at (833) 756-5936 for a free estimate. We know where San Francisco projects stall, and we plan around it before you commit.
Why Iron Beam Contractors Is San Francisco’s Preferred General Contractor Company
San Francisco homeowners bring us in because the job requires more than a rotating cast of subs. General Contractor work here means coordinating structural, plumbing, electrical, and finish trades on a site where the staging area might be a single parking space. Our crews have run jobs in the Inner Mission, the Outer Sunset, and up the steep blocks of Noe Valley, and we know how the San Francisco Department of Building Inspection and Planning Department review process actually moves. Nolan Driscoll leads our team with a focus on sequencing work so inspections don’t stall behind a missed party-wall notice or a forgotten 72-hour demolition filing. Homeowners tell us the difference is that we quote constraints honestly: staging, access, review timelines, and real material costs, not a rosy number that bloats later. That’s why San Francisco repeat clients call us when the second project comes.

General Contractor Services in San Francisco
General Contractor Services in San Francisco cover the full scope of residential remodeling, from interior gut renovations to exterior envelope work and outdoor hardscape. A typical San Francisco project runs $16,520 to $53,100 for a kitchen remodel, $10,620 to $33,040 for a bathroom remodel, and $53,100 to $153,400 for a home addition. The ranges reflect what actually happens on a dense, historic lot: plaster removal, soft-story seismic upgrades, electrical service upgrades, and the staging constraints that come with a crew working off a shared driveway. Iron Beam runs one contract and one point of contact through all of it.
Interior Remodeling and ADUs
Interior work in San Francisco changes fast once the walls open. Knob-and-tube wiring, failing original brick chimneys, and soft-story garage levels are common in pre-1950 row houses across the Mission and Bernal Heights. We sequence a prescriptive seismic upgrade around the load-bearing walls, then build the new kitchen or bath on a structure that actually meets current code. For ADU construction, budget $106,200 to $259,600 on a typical hillside lot, and expect engineering review for shoring and slope stability.
Exterior and Structural Work
Roof replacement in San Francisco runs $9,440 to $23,600, and window replacement $5,310 to $17,700. Moisture is the constant threat here: the marine layer sits on exterior paint and siding for months, and winter rain finds every flashing seam. We pull permits, file the neighbor notices, and use systems like James Hardie siding where exterior durability matters most.

Construction Company in San Francisco
Construction Company work in San Francisco is a different animal from suburban building. Every project contends with the San Francisco Building Code’s shadow and historic-resource provisions, the 72-hour notification rule before demolition or foundation work, and the practical reality of staging on a street with no curb space. A paver patio installation runs $4,130 to $12,980, a paver driveway $8,260 to $21,240, and a full home addition $53,100 to $153,400. Iron Beam Contractors manages the scope, the trade schedule, and the discretionary review process as one integrated job, not a list of separate headaches.
Hillside Excavation and Shoring
Any excavation deeper than 5 feet on a San Francisco hillside lot triggers a strict shoring plan and slope-stability review. We handle the geotechnical referral, the shoring design, and the sequencing so the foundation work doesn’t put lateral pressure on the neighbor’s retaining wall. On steep blocks like 20th Street in Bernal Heights, that’s the difference between a clean pour and a red-tagged site.
Outdoor and Hardscape Construction
Outdoor living in San Francisco usually means a small yard, a steep grade, and a drainage problem. We build paver patios, driveways, and retaining structures specified for longevity, using vendors like Belgard and Unilock for paver systems. A paver patio in a Noe Valley rear yard has to handle winter rain without pushing water into the garage level below, so we detail the base and drainage from day one.
Trusted Brands We Service in San Francisco
Iron Beam Contractors is authorized to work with over 50 named material and product brands across cabinetry, countertops, roofing, windows, hardscaping, plumbing fixtures, and ADU systems. We specify KraftMaid cabinetry for San Francisco kitchens where cabinet dimensions have to fit a tight, out-of-square row house wall. For prefab and ADU installations, our partnerships with Plant Prefab and Tuff Shed let us offer options most remodelers can’t. James Hardie siding and Schluter waterproofing are our defaults for exterior and wet-area work. Because we source directly through these manufacturer relationships, San Francisco clients aren’t stuck waiting on a supply house across the bridge or paying a markup for materials we could have specified in-house.

AfterCommon General Contractor Problems We See in San Francisco Homes
- Soft-story garages and raised foundations. Pre-1950 row houses in the Mission and Noe Valley often have a garage level with a living space above, and the lateral system is a single unreinforced wall. The mandatory retrofit changes the whole remodel scope.
- Original brick chimneys that crack free of the roofline. Seismic movement and decades of moisture cycles leave many chimneys unsafe. We see this on nearly every full home remodel in the Outer Sunset.
- Knob-and-tube wiring hidden inside plaster walls. Opening a wall for a kitchen remodel in a 1920s Victorian frequently reveals wiring that hasn’t been touched in a century. The upgrade has to be scoped before the rough-in schedule locks.
- Staging and access conflicts on shared driveways. A tight Bernal Heights lot with one shared stair and no street parking changes the entire logistics plan. Material drops, debris boxes, and crew parking all have to be part of the quote, not an afterthought.

FAQs About General Contractor in San Francisco
A tight lot changes the quote because staging, parking, and material access become line items. On a row house lot with no curb space and a shared driveway, we have to schedule material drops, debris removal, and crew parking precisely, and that costs real money. Call (833) 756-5936 and we’ll walk the site and show you the constraints in our line-item quote.
The 72-hour rule is a city requirement to notify neighbors and the Department of Building Inspection at least 72 hours before any demolition or foundation work starts. We file it for you, and we time it so adjacent owners know exactly when the concrete pour and hammer work will land.
Yes, and it’s a common project here, but hillside ADUs and garage conversions trigger shoring and slope-stability review once excavation goes past 5 feet. Budget $106,200 to $259,600 for a hillside ADU, and expect engineering for the lateral system and drainage. We handle the geotechnical referral and the permitting sequence as one scope.
The Planning Department reviews additions and remodels on overlay-district lots for shadow impacts on public parks and open space, and for any work that affects a historic resource. That review can add months if it isn’t sequenced properly. We file early, run the discretionary review in parallel with structural design, and don’t let it ambush your rough-in schedule.
A permit locks the scope to the code at the time of filing, and it protects you when the building inspector walks the job. On a walled-in San Francisco remodel, unpermitted structural or electrical work will cost you at resale and can stall a future sale. We pull every permit, pass every inspection, and close out with the city record clean.
