Does Baker City, OR need an earthquake retrofit?

Baker City 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. Nationally, Baker City ranks above 74% of the 4,875 cities in this dataset for seismic hazard - the 74th percentile.

Where Baker City sits in Oregon

USGS's underlying values for Baker City: 0.15g peak ground acceleration, 0.336g at short period, 0.119g at 1 second. Within Oregon alone, Baker City ranks 78 of 80 cities by seismic hazard - the 3th percentile in-state. Baker City has a population of about 10,135.

Retrofit economics for Baker 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 Oregon 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 Oregon.

Insuring against this, not just retrofitting

A Baker 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.
