In 1999 the City of Seattle and surrounding jurisdictions created a standard retrofit plan. This collaboration was put together to allow homeowners to do their own retrofits 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.
