Berlin, MD: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Berlin in Seismic Design Category A: Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. Nationally, Berlin ranks above 14% of the 4,875 cities in this dataset for seismic hazard - the 14th percentile.

Where Berlin sits in Maryland

The raw figures: peak ground acceleration 0.042g, short-period spectral response 0.089g, 1-second spectral response 0.036g. Among 46 Maryland cities in this dataset, Berlin ranks 46 for seismic hazard, the 0th percentile within the state. About 5,349 people live in Berlin, Maryland.

What a retrofit costs in Berlin

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

Insuring against this, not just retrofitting

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 Berlin address.
