Seismic Retrofits

We help homeowners make their homes more earthquake safe by evaluating the existing building and discussing what retrofits would most benefit their structure.

A seismic retrofit is any modification of an existing structure that would make it more resistant to an earthquake. Some examples of a retrofit include:

  • Bolting of mudsills to foundation (see pictures)
  • Installing plywood shearwalls on particularly weak walls of the house
  • Adding seismic hardware to critical connections
  • Replacement/Repair of foundation
  • Bracing of basement cripple walls

Some cities have incentives in place for homeowners to retrofit their home. These incentives include reduced permit fees and even refunds. For more information about seismic retrofits and some of the municipal incentives, see the article on retrofits.
