Engineered Seismic Protection You Can Rely On
Many older California homes were never properly anchored or braced, leaving them vulnerable during earthquakes. Our licensed engineers inspect your crawl space, assess structural weaknesses, and design retrofit solutions that meet current seismic codes, qualify for insurance discounts, and help safeguard your property.
All featured projects are real, city-approved plans.
Why You Need This
Why California Homes Need Seismic Retrofitting
Most pre-1980 homes were built before modern seismic codes—leaving them structurally vulnerable when the next big earthquake hits.
Risks of an Un-Retrofitted Home
- Cripple wall collapseUnbraced short wood walls between the foundation and first floor are the most common failure point in Bay Area earthquakes.
- Foundation sliding off mudsillWithout anchor bolts, the house can shift laterally off its foundation—causing major structural and utility damage.
- Soft story failure in multi-unit buildingsOpen-front ground floors (parking, retail) are highly vulnerable to pancake collapse under seismic loading.
What Seismic Retrofitting Achieves
- Reduced earthquake damage and displacement riskFEMA studies show properly retrofitted homes are significantly more likely to remain habitable after a major quake.
- Insurance premium discountsCEA and many private insurers offer verified discounts for homes with certified seismic retrofits.
- EBB grant eligibility (up to ,000)The state-funded Earthquake Brace + Bolt program offsets retrofit costs for qualifying homeowners.

Our Retrofit Services
What We Do for Your Home
From crawl space assessment to permit-ready plans, Cecilia Home handles every step of the seismic retrofit process.
Cripple Wall Bracing
We design and document structural plywood shear panels to brace unprotected cripple walls—the most critical retrofit for pre-1980 wood-frame homes.
Foundation Anchor Bolting
Anchor bolts secure the mudsill to the concrete foundation, preventing lateral sliding during seismic events. We specify bolt size, spacing, and hardware per current codes.
Soft Story Retrofit
Required by ordinance in many California cities, we engineer moment frames and shear walls to strengthen open ground-floor buildings under seismic ordinance compliance.
EBB Grant Documentation
We prepare the licensed engineering reports and stamped drawings required to qualify for the California Earthquake Brace + Bolt grant program—up to ,000 in rebates.

Very knowledgeable about the EBB program requirements. The stamped plans were accepted by the city on the first submission.
I felt a lot safer after seeing the engineer crawl under the house and document everything properly. Worth every dollar.

FAQ
Seismic Safety Questions
Essential information about earthquake retrofitting for California homeowners.
Haven't found what you're looking for?
If your home was built before 1980, it likely needs a retrofit. Many older homes lack proper foundation bolting and cripple wall bracing—making them at higher risk of sliding or collapse during an earthquake.
The Earthquake Brace + Bolt (EBB) program provides state-funded grants of up to $3,000 to help homeowners pay for seismic retrofit work. We assist with the engineering documentation required for program eligibility.
Yes. The California Earthquake Authority (CEA) and many insurance providers offer premium discounts for homes that receive a certified seismic retrofit.
Most single-family retrofits take 1–3 days of construction. Work is typically done in the crawl space with minimal disruption to daily life.
Yes. Seismic retrofitting is a structural upgrade and requires a building permit. We prepare the engineering plans and handle city submission for you.
A cripple wall is the short wood wall sitting between the foundation and the first floor. If unbraced, it is one of the weakest parts of older homes and can collapse during lateral earthquake forces.
