San Francisco is a structural engineer's city: dense blocks of Victorian and Edwardian flats, soft-story buildings with garages tucked under living space, homes on steep hills, and neighborhoods built on everything from bedrock to bay fill. The city's mandatory soft-story retrofit program and demanding plan-check make experienced engineering essential. We serve clients across San Francisco with retrofits, foundation upgrades, remodels, and additions, engineered for the specific soil, slope, and code conditions of each neighborhood.

Engineered for San Francisco's conditions
Mandatory Soft-Story Retrofits
San Francisco requires many wood-frame, multi-unit soft-story buildings to be retrofitted. We design the steel moment frames and reinforced walls needed to comply, with documentation formatted for SF's program.
Victorian & Edwardian Flats
SF's iconic flats were built with balloon framing and minimal lateral bracing. Opening floor plans, adding units, or excavating for a garage all require careful structural engineering to keep these tall, narrow buildings stable.
Varied Soils: From Bedrock to Bay Fill
Neighborhoods like the Marina sit on fill vulnerable to liquefaction, while others sit on rock or sand. We match foundation design to the actual ground conditions in your part of the city.
Permitting
We prepare stamped structural documents for the San Francisco Department of Building Inspection (SFDBI), including the calculations and details their reviewers require.
San Francisco structural engineering FAQs
Do you handle San Francisco soft-story retrofits?
Yes. We design compliant soft-story retrofits (steel moment frames and reinforced walls) with the documentation SF's mandatory program requires.
Can you engineer opening up a Victorian floor plan?
We do this regularly. Removing bearing walls in SF flats requires engineered beams, posts, and load-path detailing, which we provide as stamped plans.
I'm buying a multi-unit building in SF. How do I know if its soft-story retrofit was done?
Most buildings covered by San Francisco's Mandatory Soft Story Program have completed their retrofits by now, and compliance status is public record through SFDBI. Before you buy a wood-frame building with tuck-under parking or ground-floor commercial space, verify that any required retrofit was completed and finaled. An open notice of violation can complicate financing and the sale. We review retrofit documentation, evaluate buildings that fell outside the program, and design upgrades where work is still needed.
