Does Easley, SC need an earthquake retrofit?

Easley carries Seismic Design Category C under USGS's ASCE 7-16 model. Moderate seismic hazard. Code adds irregular-building restrictions and requires bracing of some nonstructural components (e.g. tall shelving, water heaters) in addition to structural detailing. Rank it against the rest of the country and Easley sits at the 78th percentile for seismic hazard among 4,875 US cities.

Easley by the numbers

The raw figures: peak ground acceleration 0.221g, short-period spectral response 0.359g, 1-second spectral response 0.1g. Among 66 South Carolina cities in this dataset, Easley ranks 22 for seismic hazard, the 68th percentile within the state. About 27,001 people live in Easley, South Carolina.

Bracing and bolting: the actual cost

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for South Carolina. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.

Earthquake insurance for a Easley home

Outside California, earthquake coverage is typically sold as an endorsement added to a standard homeowners policy, not a separate product - worth asking about directly when getting a home-insurance quote for a Easley address.
