Structural Engineering
Structural Engineering Services
From new construction to additions, ADUs to remodels — we deliver code-compliant, contractor-ready plans backed by a licensed P.E. stamp. East Bay, Los Angeles County and Sacramento Region homeowners, architects, and builders have trusted KSF since 1988.

Why KSF
Plans that build the way they read.
Most projects stall because the plans don’t survive contact with a real site. We engineer for the build that actually happens — with the contingencies, callouts, and conversations your contractor will need on day one.
A drawing set that gets pulled
Stamped plans with clear load paths, member sizes, and connections — so your contractor knows what to build and plan check has fewer questions. If the city sends comments, we answer them.
So your project moves forward instead of sitting in plan check.An engineering team that answers the phone
Mid-project questions don’t hold up a slab pour. We respond the same day, walk the framer through a tricky beam, and reissue revisions same-week when something needs to change.
So a phone call solves the problem — not a two-week delay.A team that has done this before
Four decades of East Bay practice — now brought to Los Angeles County and the Sacramento Region — means we’ve already seen your foundation type, your jurisdiction’s plan reviewer, and the seismic detail your engineer thirty years ago left undocumented.
So your project gets engineered, not experimented on.A pragmatic path to permit
We coordinate with architects, designers, contractors, and city plan checkers so the engineering integrates with the build — not against it. Less back-and-forth, fewer revisions, lower total cost.
So you spend money on the project, not the paperwork.
What we engineer
Eight services. One licensed engineering team.
Residential and commercial. New builds, retrofits, additions, and everything in between. If it carries load, we can stamp it.
New construction structural design
Full structural design for single-family homes, multi-unit residential, and commercial buildings — from foundation to roof framing.
So you break ground with a plan that actually fits the lot.ADUs and home additions
Engineering for accessory dwelling units, second stories, in-law suites, garage conversions, and additions. We size new framing, tie it into existing structure, and detail the connections for your framer and the city inspector.
So your addition feels like part of the original home, not a bolt-on.Remodel and renovation engineering
Whole-house remodels, kitchen openings, structural reconfigurations. We assess what’s there before we redesign what’s next.
So your remodel doesn’t inherit a problem.Structural calculations and plans
Stamped engineering calculations and drawings prepared for plan check in Oakland, Berkeley, Alameda, San Francisco, and Los Angeles County jurisdictions.
So your permit application goes in complete.Load-bearing wall modifications
Open up the kitchen. Take down the wall between two rooms. We engineer the beam, the posts, and the foundation reaction — with clear notes for your contractor.
So your open floor plan stays open and safe.Permit and construction support
We respond to plan-check comments, redraw details for the contractor, and answer field questions during construction. Engineering doesn’t end when the plans get stamped.
So you have an engineer on call — not a stranger on a drawing.Residential and commercial projects
From a single ADU to a multi-tenant tilt-up. The principles don’t change with the building type; the experience does. We bring both.
So your project gets matched to the right engineer, regardless of scale.Architect and contractor coordination
We work alongside your existing design team — reviewing schematic drawings, attending coordination calls, and providing structural input early enough to influence the design.
So engineering joins the project before it becomes a problem.
