Does Hammond, IN need an earthquake retrofit?

Hammond carries Seismic Design Category B under USGS's ASCE 7-16 model. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Hammond ranks above 37% of the 4,875 cities in this dataset for seismic hazard - the 37th percentile.

How Hammond compares

The raw figures: peak ground acceleration 0.059g, short-period spectral response 0.119g, 1-second spectral response 0.066g. Among 126 Indiana cities in this dataset, Hammond ranks 89 for seismic hazard, the 30th percentile within the state. About 76,030 people live in Hammond, Indiana.

Bracing and bolting: the actual cost

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

Earthquake insurance for a Hammond 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 Hammond address.
