Buying a Property with Unpermitted Work

[Juan Carlos Castillo]

This will be my first property, it was listed in the MLS as a duplex and zoned in multifamily. The issue is when the bank went to the an appraisal, there is only one water meter in the property and they are saying it is technically has a use code for single family, most likely meaning that the efficiency addition to the home was done unpermitted.

My realtor is talking about telling the home owner to open what is currently a permanent door and removing items from the kitchen and having them redo the appraisal/application as a SFH. What are some precautions I should take moving forward? I really like the home and want to continue, but don't want to be hit later with some random building inspection that may find faulty/out of code work.
