Zoning Question

[Robert Fairchild]

Hi All - I have placed an offer on a home that had some questionable work completed.  The original home was a 3 br 3 bath home.  The home had 3 bedrooms and 2 baths added.  The previous owner closed in the garage and added a makeshift room with a bath and added an addition that contains the other bedrooms and baths.  

My concern is that on county tax website the original home specs are there.  If I were to have my offer accepted who I have to convert the home back to the original configuration?

thanks!
