Do I Need an Engineer Stamp for My Project in San Francisco?

DBI requires sealed drawings for commercial building permits across the structural, mechanical, electrical, plumbing, and civil disciplines, plus Title 24 energy documentation. The PE stamp must show the licensee's name exactly as licensed, the California license number, and the expiration date; the SE seal applies to structural work on significant structures. California licenses by discipline, so the stamping engineer must hold the discipline covering the work. The city's administrative bulletins layer requirements onto the base code — submittal formats, detailing standards, and review procedures that differ from Los Angeles or San Diego practice. An engineer who stamps San Francisco work from the state code alone, without the bulletins, produces a submittal DBI will correct heavily. Apex Grid Engineering assigns California-licensed engineers familiar with the San Francisco amendments as engineers of record on every SF project.

The seismic program is the city's defining feature. New construction in the highest seismic design categories needs special moment frames, special shear walls, or equivalent lateral systems with the full special detailing — the drawings show the category, the system, and the detailing, and DBI checks all three. For existing buildings, the mandatory soft-story retrofit ordinance and the concrete building evaluations create engineer-led compliance tracks with city deadlines. Soils in the eastern city — Bay Mud and liquefiable fills — push foundations to deep piers or piles per the geotechnical report, and the structural drawings must implement the report. Title 24 compliance forms must match the drawings. The Planning Department's separate track — historic review, neighborhood notification, conditional use — runs alongside DBI review, and the project team coordinates both from the start.

Use this checklist before your San Francisco permit set is sealed: • Engineer of record holds an active California license in the correct discipline, verifiable on the BPELSG roster • SE seal applied where significant-structure rules require it • Seal shows name exactly as licensed, license number, and expiration date • Seismic design category, lateral system, and special detailing shown on the drawings • Administrative bulletins applied — not just the state building code • Geotechnical report addresses Bay Mud, liquefaction, or fill where present • Title 24 compliance forms match the drawings • Planning Department track (historic, notification, conditional use) coordinated with DBI review
