Why would you let these people into your home? Code enforcement or the Fire marshall. Is there some law that states that they can search/inspect your home without a court order? Even more violating is because it is on the word of a third party. That is scary buisness if they can come in when ever they so choose. They would have been turned away at the door at my house.
Anyone ever heard of just not responding to public officials? I had a building inspector with a complaint about one of my outbuildings leave notices at my front gate for six months once, I just ignored him and he moved on to greener pastures. As far as letting any of those tax payer funded lackies in my home...never happen unless they have two SWAT units backing them up, even then I could take em if need be.
