Seismic retrofitting in LA runs $5,000-$70,000 over 3-7 days for most homes, depending on foundation type and retrofit scope. California Earthquake Authority's Brace + Bolt program offers up to $3,000 in rebates for qualifying retrofits on homes built before 1980 with raised foundations and cripple walls.
Our structural specialists inspect your home's foundation, cripple walls, and connection points to identify earthquake vulnerabilities. We assess your home against current California seismic standards.
Outcome:
A detailed report of your home's seismic weaknesses and recommended retrofit measures.
Based on the assessment, we develop an engineered retrofit plan specific to your home's construction. You'll receive a comprehensive quote detailing all work, materials, and compliance with California's Earthquake Brace + Bolt standards.
Outcome:
A professionally engineered retrofit plan with clear scope and transparent pricing.
Buildda handles all permit applications and, if eligible, enrolls your project in California's Earthquake Brace + Bolt (EBB) program for potential rebates up to $3,000. We ensure compliance with local building codes.
Outcome:
All permits secured and available rebate programs identified for your retrofit.
Our crews install new foundation anchor bolts, securing your home's mudsill to the concrete foundation. We use epoxy-set or expansion bolts spaced according to engineering specifications.
Outcome:
A securely bolted connection between your home and its foundation.
We reinforce cripple walls (short stud walls in crawl spaces) with structural plywood sheathing. This prevents the most common earthquake failure mode in older California homes.
Outcome:
Strengthened cripple walls that resist lateral earthquake forces.
We install framing anchors, hold-downs, and metal connectors at critical points. Water heater strapping and gas line flexible connectors are added for additional safety.
Outcome:
Complete structural connections and utility safety measures throughout your home.
After completing the retrofit, we schedule the required city inspection. Upon approval, your home receives official certification of seismic retrofit compliance.
Outcome:
Official certification documenting your home meets current seismic safety standards.
Buildda provides complete documentation of your retrofit for insurance purposes. Many insurers offer earthquake insurance discounts for retrofitted homes. We assist with any required paperwork.
Outcome:
full documentation for insurance benefits for your family.

Protect Your Home from Earthquake Damage
Seismic retrofitting in LA runs $5,000-$12,000 for basic cripple-wall bracing and bolt-down (typical for pre-1960 homes), $12,000-$28,000 for full foundation-perimeter bolt-down with shear-wall plywood, and $28,000-$70,000 for hillside homes with caissons or major foundation work. Insurance discounts of 5-25% on earthquake coverage are common after a documented retrofit. Some California cities require seismic evaluation when a home is sold; check your local ordinance.
California Earthquake Authority's Brace + Bolt program offers up to $3,000 in rebates for qualifying retrofits on homes built before 1980 with raised foundations and cripple walls. The retrofit itself is a high-value safety investment for older California homes, since the cost is small relative to typical earthquake damage. Most permits issue in 2-4 weeks; install takes 1-2 weeks. Cost variance comes from foundation type (raised wood-frame foundations are the standard target; slab-on-grade homes typically don't need this work), home size (a 1,200 sq ft bungalow needs fewer anchor bolts and shorter cripple-wall plywood runs than a 3,500 sq ft Spanish revival), Earthquake Brace + Bolt program eligibility (we check the eligibility map at the assessment stage), engineering scope (most retrofits use a pre-approved Standard Plan A; complex foundations may need a custom-engineered solution at $1,500-$4,000), and any soft-story concerns where the cripple wall is taller than 4 feet and may need additional reinforcement. We engineer to IEBC Appendix A4 (CA-amended), with the engineer's stamp on the plans and Buildda holding license #1131088 on the permit. 2-year workmanship warranty on the install.
