Field notes
The homepage presents a searchable city directory alongside state listings, then maps each location to the A-to-F seismic design categories attributed to USGS and ASCE 7-16. Its cost framing separates typical bracing and bolting costs from California's Brace + Bolt grant, with the page listing $3,000–$7,000 for the former and $3,000–$10,000 for the latter. It also warns that foundation type, age, and construction can change what an individual house needs.
