Structural Engineer in San Francisco, CA
From Victorian flats in the Mission to homes on the sandy slopes of the Sunset, Oaktown Engineers brings licensed structural expertise to San Francisco's uniquely challenging building conditions.
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.
Permit-ready for San Francisco
We prepare stamped structural documents for the San Francisco Department of Building Inspection (SFDBI), including the calculations and details their reviewers require.

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.
