Does Swissvale, PA need an earthquake retrofit?

Swissvale carries Seismic Design Category B under USGS's ASCE 7-16 model. Low seismic hazard.

That puts Swissvale in the 22th percentile nationally for seismic hazard - higher than 22% of the 4,875 US cities USGS was checked against here.

Where Swissvale sits in Pennsylvania

USGS's underlying values for Swissvale: 0.042g peak ground acceleration, 0.089g at short period, 0.045g at 1 second. Within Pennsylvania alone, Swissvale ranks 153 of 193 cities by seismic hazard - the 21th percentile in-state. Swissvale has a population of about 8,280.

Retrofit economics for Swissvale

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 Pennsylvania 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 Pennsylvania.

Earthquake insurance for a Swissvale home

A Swissvale 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.
