Does Bartlett, TN need an earthquake retrofit?

Bartlett carries Seismic Design Category D under USGS's ASCE 7-16 model. High seismic hazard - this is the category most of coastal California, the Pacific Northwest, and other active fault regions fall into. Code mandates significant seismic detailing and restricts irregular structural configurations. This is the category the Brace + Bolt scope (cripple-wall bracing, foundation bolting) is built for. Rank it against the rest of the country and Bartlett sits at the 92th percentile for seismic hazard among 4,875 US cities.

Where Bartlett sits in Tennessee

USGS's underlying values for Bartlett: 0.564g peak ground acceleration, 0.948g at short period, 0.322g at 1 second. Within Tennessee alone, Bartlett ranks 9 of 104 cities by seismic hazard - the 92th percentile in-state. Bartlett has a population of about 56,708.

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 Tennessee 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 Tennessee.

Earthquake insurance for a Bartlett home

A Bartlett 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 Bartlett's figures come from
