Fred, we have no idea where you are, but I would think it’s up to the local authorities. Howver, if the house is not secured, why not just have them access it descretely. That would be in terms of looking at it for bids. You wouldn’t want to do any work on it until you close and own it.
I have just put a contract on a red tagged house. It needs foundation,roof,electrical,and structual work. Do I need code inforcements permmission before I can bring in these contractors?
