There is a reason for pulling building permits, and say answer no and move is wrong. We teach our children to answer the right way, we as adults should do the same. I would pull the permit and pay any and all fees. Their are companys that can help in pulling permits. I should know I own one Affective Permit Processing in Portland Oregon, www.ezpermits.com. If you do any work check with your local government for whats called Home owner night, they will walk you through the process. As for Mr X if he or she is contractor, I would think twice before hiring they to do any work without a permit.
