The Washington Association of Building Officials (WABO) is passionate about building and life safety. Protecting homes against earthquake damage is one area that WABO has dedicated resources to.   The application process for Earthquake Home Retrofit Permits (also known as Project Impact) can greatly increases the speed by which a permit can be issued. Jurisdications will provide suggestions, called prescriptive plan sets, on how to retrofit homes. These plan sets help you obtain the Earthquake Home Retrofit Permit quickly and easily. They also eliminate the need to hire a design professional to develop drawings. If projects do not meet the requirements of the prescriptive plan set, a voluntary seismic retrofit designed by an engineer can be submitted.

Home retrofit plans address common locations of earthquake damage to single-family homes by following the ABC of home earthquake retrofits:  Anchor the home to a foundation;  Brace the wall between the foundation and the first floor; and Connect that wall to first floor framing.

*WABO is in the final stages of updating the Standard Earthquake Home Retrofit Planset and anticipate a release date in mid November 2020.
