§ San Francisco fast facts

QUICK ANSWERS.

Do foundation contractors need a separate license to do seismic retrofit work in San Francisco?

No separate license is required beyond a California C-61/D-04 (Concrete) or C-8 (Concrete) contractor's license, or a Class B General Building contractor license. However, all foundation and structural work in San Francisco requires a permit pulled through DBI, and soft-story retrofit work must be designed or reviewed by a licensed structural engineer before permit issuance.

What soil conditions should a foundation contractor account for when bidding jobs near the San Francisco Bay waterfront or in the Marina District?

Much of the Marina District and waterfront areas are built on artificial fill and Bay Mud, which can liquefy in a seismic event. Bids for these areas should include allowances for deep pier systems, potential contaminated soil disposal (especially near former industrial sites), and dewatering. Unit costs for excavation in these zones run materially higher than hillside bedrock sites in the same city.

§ Why foundations pros in San Francisco use Estimate.Pro

THE BID ENGINE.

## Foundation Estimating in San Francisco Is Not Like Anywhere Else San Francisco sits on some of the most geologically complex ground in the country. You are bidding jobs that involve soft Bay Mud, serpentinite bedrock, expansive clays, and the Uniform Building Code legacy layer that still shapes how the City interprets the 2022 California Building Code. A flat-rate estimating template built for a subdivision contractor in the Central Valley does not cover you here. Estimate.Pro is built for the trades, and foundation work in SF carries conditions that have to show up in the numbers before you send a bid. --- ## What Drives Foundation Costs in San Francisco **Seismic requirements add scope.** The City and County of San Francisco enforces Chapter 4 of the 2022 California Building Code with local amendments. Soft-story retrofit work under the mandatory program (Ordinance 66-13 and its successors), cripple-wall bracing, moment frames, and anchor bolts to sill plates are line items you have to price individually. If your estimate lumps them into a single "seismic upgrade" number, you are either leaving money on the table or bidding yourself out of the job. **Hillside and fill lots demand soil-specific unit costs.** Noe Valley, Twin Peaks, Bernal Heights, and the Sunset all present different excavation conditions. Import fill, export of contaminated material from former industrial parcels in SoMa or Dogpatch, and dewatering on lots near the water table each carry their own cost codes. Your workspace in Estimate.Pro lets you save material and subcontractor unit costs by condition type so you stop re-entering them from memory. **Permit fees in San Francisco are among the highest in the state.** A foundation replacement or underpinning permit runs through the Department of Building Inspection (DBI). Plan check fees scale with valuation; for a mid-range foundation repair valued at $80,000, the combined permit and plan check fee typically lands between $2,800 and $4,200 before any state surcharges. That is a real line item in your bid, not a footnote. **Labor rates reflect the market.** Prevailing wage on public work in San Francisco County for operating engineers and laborers in excavation and foundation work runs $95–$115/hr fully burdened as of recent DIR determinations. Private residential work trades closer to $75–$95/hr depending on crew composition. Estimate.Pro lets you set and save your own labor rates in your cost workspace so the math is yours, not a national average that does not reflect your actual payroll. --- ## How the 8-Minute Bid Works for Foundation Contractors Walk the site. Use Estimate.Pro's AR measurement tools on supported devices to capture dimensions of the foundation perimeter, crawl space access points, and affected wall sections. On older devices or photo-based captures, measurements are flagged as estimates so you know what to verify before the bid is final. The AI scope-of-work engine turns your walkthrough notes into a line-item draft. For foundation work in San Francisco, that means it prompts for: - Soil classification and bearing capacity notes - Pier type (drilled concrete, helical, push pier) and count - Cripple wall framing linear footage - Anchor bolt spacing per CBC Table 2305.3 - Sheathing and hold-down hardware - Dewatering and shoring allowances - DBI permit fee estimate based on your entered job valuation You review, adjust your saved unit costs, and send a professional bid. The median time from walkthrough to sendable estimate across Estimate.Pro users is 8 minutes. --- ## Payments and Invoicing If you take deposits or progress payments, Estimate.Pro connects to Stripe Connect. On the Pro plan ($39/seat/month) the platform fee is 3%. On Elite ($79/seat/month) the platform fee is $0, and you get invoice export workflows. If you run a crew, the flat $399/month Crew plan covers the whole team. There is a free tier with no credit card required. Start there, build a real estimate for a San Francisco job, and decide if the paid plans fit your volume. --- ## Built for 25 Trades, Including Foundation Contractors Estimate.Pro supports 25 trades. Foundation contractors share the platform with structural, concrete, waterproofing, and excavation specialists, which matters when you are subbing out shotcrete or hiring a waterproofing crew and need to fold their numbers into your master bid. If you are pricing foundation work in San Francisco — retrofits on wood-frame Victorians in the Richmond, underpinning on soft-story apartment buildings in the Mission, or new-construction piers on a steep lot in Twin Peaks — Estimate.Pro gives you a field tool that matches the complexity of the work.
