Southern California homeowners have access to one of the most mature earthquake retrofit grant programs in the country. Administered by the California Residential Mitigation Program (CRMP), the combined Earthquake Brace + Bolt (EBB) and Earthquake Soft-Story (ESS) programs give qualifying owners up to $10,000 toward seismic retrofits that can dramatically reduce the odds of a home being destroyed in a major quake. For millions of Californians who bought homes in the decades before modern seismic codes took effect, the grants make a practical retrofit affordable for the first time.

Two Grant Programs, One Goal

CRMP operates two related programs, each targeting a specific type of vulnerable home.

Earthquake Brace + Bolt (EBB). This is the flagship program. It targets older, wood-framed homes with a raised foundation and a crawl space. In these homes, the house frame sits on a low perimeter wall called a cripple wall that attaches to the concrete foundation. Without bolting and bracing, the cripple wall can collapse sideways during a quake, dropping the house off its foundation.

A standard EBB retrofit does two things:

Bolts the wood frame to the concrete foundation so the house cannot slide off.
Adds plywood sheathing to the cripple walls so they resist sideways forces.

Eligible homes are generally pre-1980, one or two stories, wood-framed, and on a raised foundation.

Earthquake Soft-Story (ESS). Introduced to address a different weakness in common California housing. Soft-story homes typically have living space above a garage or open carport on the ground floor. In a strong earthquake, that ground floor can pancake. ESS grants help retrofit these homes with steel frames, shear walls, or other strengthening elements. In Southern California, ESS became active in Los Angeles and Pasadena as a pilot program, starting in 2023, for qualified owners.

Grant Amounts

CRMP offers:

Up to $3,000 for a standard EBB retrofit, available to any owner of a qualifying home regardless of income.
An additional $7,000 through the EBB Supplemental Grant, for a total of $10,000, for income-qualified households earning below specific limits tied to area median income.
Up to $13,000 for ESS retrofits in pilot cities, reflecting the higher engineering and construction costs involved.

Retrofit work for a typical EBB project often falls in the $3,000 to $7,000 range depending on house size, contractor pricing, and local conditions. That means the basic grant often covers most of the cost for smaller homes, and income-qualified households can frequently complete a full retrofit at little or no out-of-pocket expense.

Who Qualifies

Core EBB eligibility rules include:

Home is located in a participating ZIP code, with wide coverage across Southern California.
Construction is pre-1980.
Home is single-family or small multifamily, wood-framed with a raised foundation and cripple wall.
No recent retrofit has already been done.

Supplemental Grant eligibility adds income rules, typically capped at around 80% of county-level area median income.

ESS eligibility is narrower by design, since the retrofit is more complex. Owners apply during a defined registration window, and CRMP works with engineers and contractors to scope each project.

How to Apply

Homeowners apply directly through the CRMP website during open registration windows. Steps usually include:

Confirm eligibility. Use CRMP's address lookup to verify your home falls inside a participating ZIP code.
Register during an open window. Supply and demand is managed through registration periods; homeowners who miss a window wait for the next.
Select a contractor. CRMP maintains a list of contractors trained in the retrofit standards required for grant funding.
Complete the retrofit. The contractor performs the work and obtains local building department approval.
Submit for grant payment. Once the retrofit passes inspection, the grant is paid directly to the homeowner or contractor, depending on program rules.

Why Retrofits Matter

Earthquake insurance covers damage after the fact, but retrofits reduce the odds of damage ever occurring. A bolted and braced cripple wall is far less likely to collapse in a moderate to strong quake, which means the home above stays usable rather than becoming uninhabitable overnight.

Studies by FEMA and earthquake engineering researchers have repeatedly shown that seismic retrofits are among the most cost-effective uses of public safety dollars. A few thousand dollars of bracing can prevent tens or hundreds of thousands of dollars in damage and displacement. For homeowners, that translates into lower insurance deductibles, better loan terms in some cases, and much better odds of keeping their home after the next major earthquake.

Watch for Scams

Demand for retrofits has drawn opportunistic contractors. Real CRMP retrofits are performed by contractors trained in the program's standards. If a contractor approaches you unsolicited, offers a price well below market, or pressures you to sign before fully reviewing the plans, step back and verify through the CRMP website before committing.

Bottom Line

Southern California's earthquake retrofit grant programs are mature, well-funded, and proven. For owners of older, raised-foundation homes, the $3,000 EBB grant alone covers a significant share of retrofit costs, and income-qualified households can often complete the retrofit at no out-of-pocket cost through the Supplemental Grant. The ESS program pushes into more complex soft-story work. Together, they give Southern California homeowners one of the best public tools anywhere for making an older home meaningfully safer before the next quake.
