San Francisco's Integrated Design-Build General Contractor
Terrapin Construction Group serves the Bay Area from 2181 Greenwich St, San Francisco, CA 94123 as an integrated commercial general contractor operating across 38 states. We bring national-scale resources to every Bay Area project — from SoMa, the Mission, and Dogpatch to the Financial District, Silicon Valley (Palo Alto, Mountain View, Sunnyvale, San Jose), the East Bay (Oakland, Berkeley, Fremont), and South San Francisco's Biotech Bay.
We provide in-house architectural design, structural engineering, MEP engineering, preconstruction, and construction management under one design-build contract. We self-perform IMP installation, PEMB erection, commercial roofing, commercial flooring, and equipment procurement.
We know the Bay Area's challenges: the strongest union and prevailing wage market on the West Coast, San Andreas and Hayward Fault seismic requirements (SDC D/E adding 8–18% to structural), California Title 24 (the most aggressive energy code in the nation), SF DBI permitting (10–26 weeks), CEQA environmental review, the global tech capital (Apple, Google, Meta, Nvidia competing for trade capacity), and Biotech Bay in South San Francisco (Genentech, Gilead, and hundreds of biotechs driving specialized lab demand).

How Much Does Commercial Construction Cost in San Francisco?
San Francisco carries a regional cost multiplier of approximately 1.20–1.45x versus the national average — the second most expensive market in the country after New York. Costs are driven by union labor (highest on the West Coast), seismic requirements (SDC D/E adding 8–18% to structural), Title 24 energy code (3–8% to overall), CEQA, and intense tech/biotech demand competing for limited trades. SF is more expensive than Los Angeles (1.15–1.40x) and Seattle (1.12–1.28x).
SF construction costs by type: Warehouses $120–$240/SF. Offices $220–$520/SF. Restaurants $260–$550/SF. Medical $280–$650/SF. Data centers $400–$1,650/SF. Manufacturing $140–$650/SF. Cold storage $170–$400/SF. Biotech lab TI $380–$800/SF.
Key SF factors: seismic SDC D/E (8–18% structural), union labor, Title 24 + SF green building, CEQA, SF DBI permitting (10–26 weeks), tech/biotech labor competition, marine climate moisture. Use our AI estimator or schedule a meeting.
