IS YOUR HOME AT RISK?

STANDARD RETROFIT

In 1999, the city of Seattle and surrounding jurisdictions created a standard plan for retrofitting conventionally constructed houses.

 

This collaborative effort was intended to allow contractors and homeowners to retrofit home without expensive engineering costs. The plan uses the basic "ABCs of retrofit" to secure qualifying homes:

  • Anchor the house to its foundation with bolts or foundation plates

  • Brace pony walls with plywood

  • Connect the "sill plate," or top plate of the pony wall, to the rim joist of the flooring system with metal clips

​

About 25% of the homes that A-FFIX inspects qualify to use the standard retrofit plan, meaning that no special engineering is required.
