Canton, GA: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Canton is Category C. 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 Canton sits at the 74th percentile for seismic hazard among 4,875 US cities.

How Canton compares

The raw figures: peak ground acceleration 0.148g, short-period spectral response 0.265g, 1-second spectral response 0.095g. Among 148 Georgia cities in this dataset, Canton ranks 16 for seismic hazard, the 90th percentile within the state. About 38,049 people live in Canton, Georgia.

What a retrofit costs in Canton

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

Insuring against this, not just retrofitting

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 Canton address.
