Construction without Permits and then some!?

Don't let him scare you into silence. He can't do anything, and by the way they are not public record. If you call and wish to remain unknown they will keep that way. Call your cities building and safety, and also try the health department, make sure you have a police officer write a report on all that has happened so far, and don't worry when the lease is up he can't raise the rent anymore than the legal limit, if he is trying to find an excuse to evict you have a report of that as well. Later on, you will need all doentation. When you walk into court you need facts...
