Adel, GA: what USGS's seismic model says
Adel carries Seismic Design Category B under USGS's ASCE 7-16 model. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Adel ranks above 26% of the 4,875 cities in this dataset for seismic hazard - the 26th percentile.
Where Adel sits in Georgia
USGS's underlying values for Adel: 0.046g peak ground acceleration, 0.097g at short period, 0.058g at 1 second. Within Georgia alone, Adel ranks 140 of 148 cities by seismic hazard - the 5th percentile in-state. Adel has a population of about 5,752.
Bracing and bolting: the actual cost
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.
What this means for insurance
A Adel 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 Adel's figures come from
Adel's Category B 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 B does and doesn't tell you about Adel.
