Buying a home with unpermitted work (bathrooms etc)

[Roberto Rohann]

Hello all. So I’m looking at houses in the westchester and just outside of NYC area. A lot of homes have had bathroom and kitchen modifications without permits. Things such as added showers to half baths and bathrooms in basements etc. 

How will this affect me in the home buying process. Will I be stuck with a home in which I will need to obtain permits for this past work ? And possibly having to modify the work to actual code and standards. 

Also which party in the home buying process would be looking for these things ? Is it the inspector? The appraiser. 

Any help  appreciated as most of the homes in my area have had bathrooms and kitchens added in places they originally weren’t.
