SEATTLE — Hundreds of hospitals, homes, offices, and schools across the Sound are vulnerable to collapse in an earthquake.

Some of the older buildings have been retrofitted, but there is no state law requiring it, and the process can be expensive.

“A small building -- a couple hundred thousand dollars -- a 4 or 5-story apartment building -- definitely over $1 million,” said Seattle Seismic owner Ryan Vytlacil.
