We have lived in our house for about four years. Previous owner had made modifications and extensions to the original house. Plans for these modifications had been authorized by our county's permit services, so we thought all was okay. But now as we look to make some of our own changes, we are finding what looks like code violations in the work they did. We looked into the matter and it appears there is no record of final inspection of work done by the previous owner. Is the previous owner liable for these code violations or am I on my own now? thanks.......
