Earthquake Brace + Bolt supplemental grant and the flood insurance condition

By Alishahi Insurance, independent broker · CA License #4348151 · Updated October 2026 · En español

Short answer: Earthquake Brace + Bolt (EBB) pays up to $3,000 toward bracing and bolting a pre-1980, wood-frame house on a raised foundation. Households with annual income of $94,480 or less can also apply for a supplemental grant of up to $7,000, which can cover up to 100% of the retrofit cost while funds last. If your grant is $5,000 or more, funded by FEMA, and your home is in a Special Flood Hazard Area, you must keep flood insurance for the life of the structure.

Qualifying for the supplemental grant

According to EBB, you may qualify if:

  • your annual household income is $94,480 or less,
  • you said so at registration and are accepted into EBB,
  • you are selected first-come, first-served based on available funds,
  • you return the Income Verification Form within 30 days of acceptance, and
  • EBB verifies your income with the IRS.

The flood insurance condition

EBB says that if you're a supplemental grant recipient in a Special Flood Hazard Area and your grant is $5,000 or more and FEMA-funded, you must sign a notarized form before payment. It commits you to:

  • keep flood insurance for the life of the structure, even after a sale,
  • maintain the property under floodplain management rules, and
  • record a notice with the county stating that the property received federal hazard mitigation assistance. Under 42 U.S.C. §5154a, failing to keep flood insurance can bar future federal disaster assistance for a flood.

What this means for your insurance

  1. Check the FEMA Flood Map Service Center for your address before you accept a large supplemental grant.
  2. Price flood coverage first. NFIP policies generally have a 30-day wait before they take effect.
  3. Ask about the CEA retrofit discount. A qualifying retrofit can earn at least 5% off CEA earthquake premiums under Insurance Code §10089.40.
  4. Keep permits, invoices and photos of the work.
