In 1999 the City of Seattle and surrounding jurisdictions created a standard retrofit plan.  This Project Impact collaboration was put together to allow homeowners to do their own retrofits without expensive engineering costs.  The plan uses the basic ABC’s of retrofit to secure qualifying homes.  “A” for anchor the house to its foundation with bolts or foundation plates; “B” to brace the pony walls with plywood; “C” to connect the sill plate or top plate of the pony wall to the rim joist of the flooring system with metal framing clips. 

About 25% of the homes A-FFIX Retrofit inspects will qualify to use the standard plan.  The City of Seattle offers a monthly class to homeowners interested in doing their own retrofit work or who would like to know more about the retrofit process.  Bruce Schoonmaker, who began the A-FFIX Retrofit company in 1999, has been helping teach these classes for almost 20 years. Project Impact is the city program for emergency management events. Follow this link to find when the next class for homeowners will be.

Below are 8 reasons to schedule your retrofit.


Retrofit brings a home up to current safety codes and significantly reduces the damage it will sustain during an earthquake.

95% of homes that have been shaken from their foundations during an earthquake have to be demolished.

Earthquake insurance is not adequate protection against a severe quake. Insurance does nothing to keep you safe during the earthquake itself and may not provide for interim housing while your home is being repaired after the quake.

Accommodations for people who have lost their homes in an area severely impacted by an earthquake are usually limited to schools, community centers, churches, and tents. 

Homes that are not secured properly may collapse or be shaken off of their foundations during a major earthquake, making them inaccessible and uninhabitable in the aftermath of a disaster.

Potential damages to a house not up to code in an earthquake are many times more expensive than the cost of retrofit.

A homeowner whose house has been wrecked by an earthquake must continue to make mortgage payments whether the home is habitable or not


No one should risk losing their house and home to an earthquake.
