Kennesaw, GA: what USGS's seismic model says
Kennesaw 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 Kennesaw sits at the 72th percentile for seismic hazard among 4,875 US cities.
Where Kennesaw sits in Georgia
USGS's underlying values for Kennesaw: 0.126g peak ground acceleration, 0.233g at short period, 0.091g at 1 second. Within Georgia alone, Kennesaw ranks 29 of 148 cities by seismic hazard - the 81th percentile in-state. Kennesaw has a population of about 37,740.
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.
Earthquake insurance for a Kennesaw home
A Kennesaw 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 Kennesaw's figures come from
Kennesaw'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 Kennesaw.
