Does Stallings, NC need an earthquake retrofit?

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Stallings 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. Nationally, Stallings ranks above 70% of the 4,875 cities in this dataset for seismic hazard - the 70th percentile.

How Stallings compares

USGS's underlying values for Stallings: 0.105g peak ground acceleration, 0.205g at short period, 0.084g at 1 second. Within North Carolina alone, Stallings ranks 29 of 147 cities by seismic hazard - the 81th percentile in-state. Stallings has a population of about 17,617.

Retrofit economics for Stallings

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 North Carolina 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 North Carolina.

Insuring against this, not just retrofitting

A Stallings 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 Stallings's figures come from

Stallings'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 Stallings.
