Bay Area Seismic Retrofit Contractor. before the next quake, not after.

The Bay Area's seismic risk is well known — and the City of San Francisco's Mandatory Soft-Story Program has already put thousands of buildings under retrofit deadline. Berkeley and Oakland have parallel programs. We design and install seismic retrofits across the Bay: cripple-wall bracing, foundation bolting, soft-story moment frames and steel cantilever columns, and shear wall upgrades.

Bay Area · Seismic Retrofit FAQ

Questions Bay Area homeowners ask first.

Start a Bay Area seismic retrofit brief. We'll review the notice (if any), engineer the upgrade, and write a fixed-scope contract.

  1. Does my SF building need a soft-story retrofit?
    If DBI sent you a notice — yes. Generally: pre-1978 wood-frame multifamily with parking or commercial ground floor. We can verify your address.
  2. What does a soft-story retrofit cost?
    Most SF soft-story retrofits $90K–$300K depending on size, frame, and restoration.
  3. Single-family cripple wall + bolting?
    $6K–$20K typically. CEA Brace + Bolt grant often available.
  4. How long does a Bay soft-story retrofit take?
    Most multifamily soft-story projects run 10–18 weeks on site after permit. Single-family cripple-wall and foundation bolting is typically 1–2 weeks.
  5. Can tenants stay during a Bay Area soft-story retrofit?
    Yes — we phase the work so tenants remain in place. Most retrofit work is at the parking level or perimeter cripple walls, not inside occupied units.
