I believe it. How bad is it? There are all different degrees of seismic here so it depends how much work can be done to make a project survive for a feasible cost. If it is worth it, I mean. To fix it so it can be working takes a bit of study at the site, then it is drawn up and estimated, and bid, then if it is upgraded it is safe to live there and can be sold for a much better sum. Architects do this for people, if you call them. I would do it.
