III.PROCESS

Our Seismic Retrofit Process

1. 1

   Crawlspace and structural assessment — we inspect the foundation, sill plates, cripple walls, and existing hardware to determine retrofit scope.

2. 2

   Plan Set A determination — we confirm whether your home qualifies for the pre-engineered Plan Set A retrofit, or whether a structural engineer is needed for a custom design.

3. 3

   Written proposal — itemized scope of foundation bolting, cripple wall bracing, and any soft-story or hardware additions.

4. 4

   Permit pull — every retrofit requires a building permit. We submit the application and Plan Set A documentation.

5. 5

   Crawlspace prep — moisture barriers, debris removal, and access provisions.

6. 6

   Foundation bolting — retrofit anchors installed at code spacing, epoxy-set with structural epoxy.

7. 7

   Cripple wall shear panels — structural plywood installed with documented nail pattern, hardware connections at top and bottom plates.

8. 8

   Inspection and certificate — city inspector signs off, certificate of compliance documented for your records and resale.

VI.FAQ

Earthquake Retrofit — Frequently Asked Questions

Does my house need a seismic retrofit?

If your home was built before 1980 and has a raised foundation (crawlspace, not slab), there's a strong likelihood it needs retrofitting. Soft-story homes (with a garage or open space below living area) and hillside homes are highest risk. We do a free crawlspace assessment and tell you exactly what's there.

What's the difference between Plan Set A and a custom retrofit?

Plan Set A is a pre-engineered standard for typical wood-framed homes that meet specific criteria — generally one or two stories, on a continuous perimeter foundation, with cripple walls under 4 feet. Plan Set A is faster and less expensive because no structural engineer is required. Homes that don't meet Plan Set A criteria need a custom engineered design.

How long does a seismic retrofit take?

A typical Plan Set A retrofit on a single-family South Bay home takes 1–2 weeks of on-site work, plus 2–4 weeks for permit and inspection scheduling. The work is almost entirely in the crawlspace and does not require you to move out.

Will a retrofit lower my earthquake insurance premiums?

California Earthquake Authority (CEA) policies offer a 25% premium discount for documented brace-and-bolt retrofits on qualifying homes. We provide the documentation needed to claim the discount.
