Kill Devil Hills, NC: what USGS's seismic model says

Kill Devil Hills carries Seismic Design Category A under USGS's ASCE 7-16 model. Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. Rank it against the rest of the country and Kill Devil Hills sits at the 10th percentile for seismic hazard among 4,875 US cities.

Where Kill Devil Hills sits in North Carolina

The raw figures: peak ground acceleration 0.03g, short-period spectral response 0.065g, 1-second spectral response 0.037g. Among 147 North Carolina cities in this dataset, Kill Devil Hills ranks 147 for seismic hazard, the 0th percentile within the state. About 7,742 people live in Kill Devil Hills, North Carolina.

Bracing and bolting: the actual cost

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for North Carolina. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.

What this means for insurance

Outside California, earthquake coverage is typically sold as an endorsement added to a standard homeowners policy, not a separate product - worth asking about directly when getting a home-insurance quote for a Kill Devil Hills address.
