Does Peachtree Corners, GA need an earthquake retrofit?

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Peachtree Corners in Seismic Design 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 Peachtree Corners sits at the 70th percentile for seismic hazard among 4,875 US cities.

Peachtree Corners by the numbers

USGS's underlying values for Peachtree Corners: 0.101g peak ground acceleration, 0.198g at short period, 0.087g at 1 second. Within Georgia alone, Peachtree Corners ranks 61 of 148 cities by seismic hazard - the 59th percentile in-state. Peachtree Corners has a population of about 42,638.

What a retrofit costs in Peachtree Corners

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 Peachtree Corners 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.
