Adairsville's Seismic Design Category, explained

Adairsville 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. That puts Adairsville in the 78th percentile nationally for seismic hazard - higher than 78% of the 4,875 US cities USGS was checked against here.

Where Adairsville sits in Georgia

USGS's underlying values for Adairsville: 0.234g peak ground acceleration, 0.377g at short period, 0.105g at 1 second. Within Georgia alone, Adairsville ranks 5 of 148 cities by seismic hazard - the 97th percentile in-state. Adairsville has a population of about 5,029.

What a retrofit costs in Adairsville

A full earthquake retrofit typically runs $5,000-$10,000 nationally (around $7,000 typical), driven mainly by house size and foundation type, not by Georgia specifically. California's Earthquake Brace + Bolt grant, which covers a large share of this cost, is a California-only program and does not apply in Georgia.

Insuring against this, not just retrofitting

A Adairsville homeowner cannot buy a standalone earthquake policy in most cases - it is added to an existing homeowners policy as an endorsement, so the place to start is a regular home-insurance quote.

Where Adairsville's figures come from

Adairsville's Category C and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. See the category explainer for what Category C does and doesn't tell you about Adairsville.
