Dade City's Seismic Design Category, explained

Dade City 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. Nationally, Dade City ranks above 10% of the 4,875 cities in this dataset for seismic hazard - the 10th percentile.

Dade City by the numbers

USGS's underlying values for Dade City: 0.028g peak ground acceleration, 0.059g at short period, 0.032g at 1 second. Within Florida alone, Dade City ranks 85 of 228 cities by seismic hazard - the 63th percentile in-state. Dade City has a population of about 9,662.

What a retrofit costs in Dade City

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 Florida 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 Florida.

What this means for insurance

A Dade City 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 Dade City's figures come from

Dade City's Category A 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 A does and doesn't tell you about Dade City.
