How much do general contractors charge in San Francisco?

General contractors in San Francisco typically charge 15–25% overhead and profit on top of subcontractor costs, or hourly rates of $95–$160 for hands-on work. Total project costs run 20–40% above national averages due to prevailing wages, permit fees, and the cost of operating in the Bay Area.

Do I need a permit for a kitchen remodel in San Francisco?

Almost certainly yes. San Francisco requires permits for nearly all work that involves electrical, plumbing, structural changes, or changes to a building's footprint or use. Even cosmetic kitchen remodels that involve relocating outlets or adding recessed lighting require an electrical permit. The San Francisco Department of Building Inspection (DBI) enforces this actively.

What is a Type I contract and why does it matter in San Francisco?

California contractor license law classifies licenses by type—Class A for general engineering, Class B for general building, and Class C for specialty trades. A Class B general building contractor can handle most residential renovation work. Confirm your GC holds a current Class B license with the California Contractors State License Board (CSLB) before signing.

How long does it take to get a permit in San Francisco?

Over-the-counter permits for simple projects can be issued same-day, but permits requiring plan check typically take 4–16 weeks in 2026, depending on project scope and the current DBI backlog. For large remodels or new ADU construction, factor at least 3–6 months of permit lead time into your project schedule.

What should I expect for seismic work requirements in San Francisco?

Many San Francisco homes—particularly wood-frame houses built before 1940—require seismic retrofitting under city ordinance (Mandatory Soft-Story Program) or as a condition of building permits on adjacent work. A competent San Francisco GC will flag seismic requirements during the bid phase, not after permits are pulled.

Best General Contractors in San Francisco, CA (2026)

August 24, 2026 · City Spotlight · 5 min read

Finding a qualified general contractor in San Francisco means navigating the most permit-intensive residential market in California, labor costs that run 25–40% above national averages, and seismic requirements that add scope to almost any structural project. Based on our directory of contractors operating in the San Francisco metro, here is what separates competent firms from those who will cost you time, money, and city violations.

Why San Francisco contracting is harder than most markets

San Francisco has three compounding factors that make GC selection unusually consequential:

Permit complexity: The San Francisco Department of Building Inspection (DBI) requires permits for work that many other cities treat as exempt—window replacements in historic districts, adding a bathroom to an existing plan-checked space, converting a garage to living space. A contractor unfamiliar with DBI procedures will estimate permit timelines wrong and cost you months.

Seismic requirements: The city's Mandatory Soft-Story Retrofit Program requires wood-frame apartment buildings with five or more units and soft-story conditions to be seismically strengthened. Even single-family projects in certain neighborhoods trigger seismic reviews when permits are pulled for adjacent structural work. This is not optional, and a GC who treats it as a surprise has not worked much in the city.

Labor costs: San Francisco's prevailing wage rules apply to work on city-funded projects, but union scale sets the floor for skilled trades across the entire market. Expect to pay $95–$130/hour for licensed electricians and plumbers, $80–$110/hour for finish carpenters, and $70–$95/hour for general laborers. These are 2026 figures; costs have risen roughly 8% since 2024.

What to look for in a San Francisco general contractor

California Class B license and CSLB verification

California requires a Class B (general building) contractor license for projects over $500. Verify current license status, expiration date, and bond amount directly on the California Contractors State License Board (CSLB) website. Do not accept a license number verbally—look it up yourself. Also confirm the license shows no pending disciplinary actions or prior suspensions.

San Francisco-specific experience

Ask contractors to name three completed projects in San Francisco's permit system within the last 24 months, and ask for the permit numbers. You can verify those permits on the DBI's online permit portal. A contractor pulling permits in San Jose or Oakland is a different animal—Bay Area experience does not automatically translate to San Francisco permit fluency.

Subcontractor relationships

In a tight labor market, general contractors without established subcontractor relationships will bid low and then scramble to find subs—resulting in delays and quality variation. Ask your GC who their licensed electrician, plumber, and HVAC sub are, and whether those relationships are exclusive or project-by-project. Stable long-term sub relationships correlate with better project execution.

Insurance in a seismic zone

Beyond standard general liability and workers' compensation, confirm your GC carries completed operations coverage. In earthquake country, structural defects can manifest years after project completion. Completed operations coverage protects you if a defect in construction work causes damage after the contractor has been paid and moved on. See our full breakdown of what contractor insurance to verify before hiring.

What projects cost in San Francisco in 2026

These figures are based on contractor profiles in our San Francisco directory and represent typical ranges for residential work:

Full kitchen remodel: $80,000–$180,000 for a typical San Francisco kitchen (80–150 sq ft). High-end custom work runs $200,000+.
Bathroom remodel: $25,000–$65,000 for a primary bath. A half-bath runs $12,000–$22,000.
Seismic soft-story retrofit: $8,000–$25,000 per unit in a multi-unit building, depending on building configuration and scope.
ADU construction (garage conversion): $180,000–$350,000 for a permitted garage-to-ADU conversion including city permit fees ($15,000–$40,000 in SF) and utility separation.
Foundation work: $15,000–$60,000+ for cripple wall bracing or foundation bolting; full foundation replacement runs $50,000–$150,000 depending on access and soil conditions.

San Francisco permit fees alone can add $8,000–$40,000 to projects that would cost $1,000–$3,000 to permit in other California cities. Build this into your budget estimate before comparing bids between markets.

Neighborhoods with specific contractor considerations

Mission District: Heavy historic preservation overlay in sections. Window, door, and facade changes often require Historic Preservation Commission sign-off in addition to standard DBI permits. Budget extra time and fees for any exterior work.

Pacific Heights and Presidio Heights: High-end residential work with strict neighborhood design standards. Projects here often involve working around occupied adjacent homes on narrow lots—noise ordinances (no work before 8 a.m. or after 8 p.m.) and neighbor relations matter more than in commercial corridors.

Sunset and Richmond Districts: Older wood-frame housing stock with greater likelihood of seismic retrofit requirements. Many properties also have un-permitted basement or garage conversions from previous decades—work that needs to be legalized before you can pull new permits on related scope.

SOMA and Potrero Hill: Mixed residential and light-industrial zoning with some properties subject to Maher Ordinance requirements around toxic materials remediation. Confirm your GC has dealt with site assessments on older industrial-adjacent properties.

How to vet candidates before signing

Before you sign any contract, run through the following checks. Our detailed guide covers how to vet a general contractor step by step, but the San Francisco-specific additions are:

Pull the contractor's permit history directly from DBI's permit portal—look for a pattern of permits closed on schedule vs. permits still open years after issuance.
Call the DBI's contractor information line to ask if there are any active complaints or stop-work orders on the contractor's license.
Ask specifically how the contractor handles plan check corrections—San Francisco plan checkers issue correction letters, and how quickly a GC responds determines how long your project stays in permit limbo.
Verify that the contract includes a specific permit responsibility section, identifying who pulls each permit, who pays the permit fees, and who is responsible for re-inspections after corrections. See what every renovation contract must include in our contract checklist.

Timing your project

San Francisco construction activity peaks in spring and fall. Scheduling work between November and February typically gives homeowners better GC availability and sometimes better pricing—though some contractors maintain full backlogs year-round due to high demand. Factor DBI permit processing times into your schedule: in 2026, plan check for projects requiring structural or mechanical review averages 10–14 weeks.
