Your application paperwork

Earthquake Brace and Bolt (EBB) gives California homeowners a grant to seismically retrofit an older house by bolting the home to its foundation and bracing the cripple walls. The base grant is up to 3,000 dollars, and income-eligible homeowners can apply for an additional grant of up to 7,000 dollars. You register during an open enrollment window, and the program is run by the California Residential Mitigation Program.

Steps to apply

  1. Check that your home qualifies: a wood-framed house built before 1980 with a raised foundation and cripple walls, in an eligible ZIP code.
  2. Sign up for notifications and register on the Earthquake Brace and Bolt site when the enrollment window opens.
  3. Answer the qualifying questions and receive your eligibility determination.
  4. Hire a contractor to do the brace-and-bolt retrofit, then submit documentation to receive the grant (apply for the supplemental income-based grant if eligible).
