Does Kissimmee, FL need an earthquake retrofit?

Kissimmee 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 Kissimmee sits at the 10th percentile for seismic hazard among 4,875 US cities.

How Kissimmee compares

The raw figures: peak ground acceleration 0.028g, short-period spectral response 0.06g, 1-second spectral response 0.033g. Among 228 Florida cities in this dataset, Kissimmee ranks 79 for seismic hazard, the 66th percentile within the state. About 84,756 people live in Kissimmee, Florida.

Retrofit economics for Kissimmee

Earthquake insurance for a Kissimmee home

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 Kissimmee address.
