Does Clearfield, UT need an earthquake retrofit?

Under the seismic model IBC and ASCE 7 use for new construction, Clearfield is Category D. High seismic hazard - this is the category most of coastal California, the Pacific Northwest, and other active fault regions fall into. Code mandates significant seismic detailing and restricts irregular structural configurations. This is the category the Brace + Bolt scope (cripple-wall bracing, foundation bolting) is built for. Rank it against the rest of the country and Clearfield sits at the 92th percentile for seismic hazard among 4,875 US cities.

How Clearfield compares

USGS's underlying values for Clearfield: 0.558g peak ground acceleration, 1.25g at short period, 0.439g at 1 second. Within Utah alone, Clearfield ranks 51 of 95 cities by seismic hazard - the 47th percentile in-state. Clearfield has a population of about 34,778.

What a retrofit costs in Clearfield

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 Utah 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 Utah.

Earthquake insurance for a Clearfield home

A Clearfield 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.
