01 / Who it’s for

Who it’s for.

  • Multi-family property owners under LA’s mandatory soft-story program
  • Commercial property owners pursuing voluntary retrofits
  • Investors performing seismic due diligence on at-risk inventory
  • Property managers coordinating compliance across a portfolio
02 / What’s included

What’s included.

  • Existing-condition evaluation and as-built documentation
  • Lateral force analysis per current ordinance and code
  • Retrofit design — steel moment frames, shear walls, FRP wrapping, hold-downs
  • Stamped drawings and supporting calculations
  • LADBS submittal and plan-check response
  • Coordination with the contractor and inspector through completion
03 / Project types

Common project types.

  • Duplexes through 50-unit apartment buildings
  • Mixed-use buildings with ground-floor retail or parking
  • Tuck-under parking conditions — the classic soft-story failure mode
  • Pre-1978 wood-frame and concrete tilt-up buildings
  • Voluntary retrofits ahead of refinance, sale, or insurance requirements
04 / Approach

How we approach it.

Soft-story retrofit work is one of the cleanest engineering problems in California — the failure mode is well understood, the code path is established, and the solutions are well-proven. The difference between firms isn’t whether they know how to design a moment frame. It’s how cleanly they document it, how quickly plan check goes, and how few RFIs the contractor sends during construction.

That’s what we optimize for. Our retrofit packages clear LADBS without three rounds of corrections. The contractor knows where every connection lands. Tenants get back to normal sooner. The job is supposed to make the building safer — not turn the property owner’s year upside down.

06 / FAQ

Frequently asked.

If your building is on LADBS’s mandatory soft-story list, yes — you’ve received notice and there’s a compliance deadline. Voluntary retrofits are optional but increasingly required by lenders and insurance carriers.

Engineering is typically a small fraction of total project cost. Pricing depends on building size, number of stories, complexity, and whether construction documents already exist. We provide a fixed-fee proposal after a site visit.

4–8 weeks from kickoff to permit-ready plans for a typical 4–20 unit building. We share a realistic timeline at proposal and stick to it.

Usually no. Most retrofit work happens in accessible areas — garages, ground-floor parking — and we design with construction sequencing in mind to minimize disruption.

You bid the work to licensed retrofit contractors. We stay available during construction for RFIs, field changes, and inspector coordination — no extra fee for reasonable construction-phase support.
