Earthquake Brace + Bolt: California’s Seismic Retrofit Incentive Program
Up to $10,000 toward the exact seismic upgrade so many pre-1980 Peninsula homes still need

$3,000 Base Grant Amount |
+$7,000 Additional Grant, Income-Eligible |
Pre-1980 Home Age Requirement |
Up to 25% CEA Insurance Discount After Retrofit |
Given how much of the Peninsula’s housing stock predates 1980, including large stretches of San Carlos’s Oak Park and White Oaks neighborhoods and South San Francisco’s postwar tracts, a real state grant program exists specifically to fund the exact seismic upgrade these homes commonly need.
The Problem This Program Actually Targets
Many older California homes were built with a raised foundation and a short “cripple wall,” a wood-framed wall between the foundation and the first floor, that was never bolted to the foundation or properly braced. This cripple wall carries the full weight of the house, and during an earthquake, an unbraced one can allow the entire structure to slide off its foundation. California Earthquake Brace + Bolt, known as EBB, exists specifically to fund the fix for this one, genuinely common vulnerability.
What Qualifies a Home
| Built before 1980 |
| Has a raised foundation with wood-framed cripple walls or a crawl space beneath the living area |
| Hasn’t already completed a code-compliant brace and bolt retrofit |
| Falls within an eligible ZIP code, determined by seismic risk mapping covering most of the Bay Area |
Homes built on a concrete slab-on-grade foundation generally don’t qualify, since they lack the raised-foundation cripple wall structure the program specifically addresses. Rental and other non-owner-occupied properties are also eligible now, up to five properties per owner.
What the Grant Actually Covers
Up to $10,000 Combined for Qualifying Households
The base EBB grant provides up to $3,000 toward a standard brace-and-bolt retrofit, while income-eligible households can qualify for an additional supplemental grant of up to $7,000 on top of that base award. A typical full retrofit runs $3,000 to $7,000, meaning many eligible homeowners can have the entire project covered, or close to it, between the two grant tiers.
The Real Work Involved
A code-compliant brace and bolt retrofit has two core components: bolting the house frame to its foundation, and bracing any cripple walls with plywood sheathing to California Building Code standards. For cripple walls four feet or shorter, a local building department can approve the retrofit without requiring plans from a registered architect or engineer, which keeps the process genuinely streamlined for most standard Peninsula homes.
The Insurance Benefit Afterward
Beyond the grant itself, completing a qualifying retrofit can earn California Earthquake Authority policyholders a premium discount of up to 25% on their earthquake insurance going forward. Given how much insurance costs have risen across California generally, this ongoing savings genuinely compounds year over year, well beyond the one-time grant value.
How to Actually Apply

| Submit documentation to receive the grant, and apply for the supplemental income-based grant separately if you qualify |
Key Takeaway
Given how many pre-1980 Peninsula homes genuinely have the exact cripple wall vulnerability this program addresses, EBB can fund some or all of a real, meaningful seismic upgrade, plus deliver a lasting insurance discount afterward.
Frequently Asked Questions
Does my home automatically qualify if it’s old enough?
Age alone isn’t enough; it also needs a raised foundation with cripple walls, be in an eligible ZIP code, and not already have a completed retrofit.
How much can the grant actually cover?
Up to $3,000 base, plus up to an additional $7,000 for income-eligible households, against a typical $3,000 to $7,000 project cost.
Does a retrofit actually lower my insurance costs?
Yes, qualifying California Earthquake Authority policyholders can receive up to a 25% premium discount after completing the retrofit.
Can I use this program for a rental property I own?
Yes, non-owner-occupied properties are eligible, up to five properties per owner.
