Foundation work in San Francisco
San Francisco's Department of Building Inspection (DBI) issues permits for all construction in the city through the PermitSF portal. Its 2025 plumbing and mechanical fee table (April 30, 2026 version) lists $276 for a single residential unit job such as a water service or sewer replacement, with up to two inspections. Ask DBI if that's still current, because a later fee ordinance, No. 112-26, was in the legislative file. On most new structures and many additions, an engineer holding a license must submit a geotechnical report under Building Code Sections 1803 and J104.3.
It includes foundation and retaining wall design requirements. It's uploaded with the permit application and a signed and sealed letter saying the engineer approved the final structural plans. Some projects also get third-party engineering review, where DBI selects the engineer and the owner pays, or Structural Advisory Committee review. The mandatory Soft Story program for wood-frame, multi-family buildings set September 15, 2021 as its finish deadline. Most soft story retrofit permits are reviewed over the counter, with plans brought in 2 sets.
Selling or remodeling brings in the water conservation ordinance (Housing Code Chapter 12A): owners must repair plumbing leaks and replace inefficient fixtures first, with an inspection by a DBI-certified private Residential Energy and Water Inspector. Skipping it can bring a citation. The city must use the state's liquefaction and landslide zone maps in permitting, and health questions go to Public Health's Environmental Health Branch at 415-252-3800. To see whether a building falls under the soft story mandate, search DBI's Soft Stories property list.
