Does Urbana, IL need an earthquake retrofit?

Urbana carries Seismic Design Category C under USGS's ASCE 7-16 model. 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. That puts Urbana in the 68th percentile nationally for seismic hazard - higher than 68% of the 4,875 US cities USGS was checked against here.

Where Urbana sits in Illinois

USGS's underlying values for Urbana: 0.083g peak ground acceleration, 0.172g at short period, 0.091g at 1 second. Within Illinois alone, Urbana ranks 61 of 330 cities by seismic hazard - the 82th percentile in-state. Urbana has a population of about 39,831.

What a retrofit costs in Urbana

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 Illinois 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 Illinois.

Earthquake insurance for a Urbana home

A Urbana 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.
