Red tagged-urgent help please

[Jimmy P.]

This is an absolute nightmare. The property in question was sold on a land contract this Friday. When the new owners went to the house there was a red tagged uninhabitable notice on the door dated the day before.  

I need some fast advice on how to clear this up as fast as possible. The house had some minor repairs done after it was bought and months later a notice from the inspection department was on the door saying some unpermitted work may have been done.

I asked for some advice and was told to play ball so I gave the inspector the code to get in and said call me if there were any problems and told him it was gonna be sold on Friday. This was Tuesday. The house had been inspected already by a FHA inspector and passed.

How could this happen? Any and all advice is greatly appreciated.  I need to get this cleared up asap and get the new owners in the house fast!!!
