Buying property from an auction, potential Lot split. how to?

[Naveen Desai]

Hello Wonderful BP folks, 

          I am buying a property off auction and in contract. The Lot has a house( plan to rehab and sell), and also an adjoining lot. The lot has access from street in the front and back. However currently it is coming as a single LOT.  I feel there is potential to split the home and this lot. How do I go about it? Will I need an attorney's help to make a proposal and talk to city or or just talking to the city- town planning would be good? Is there any other department I should get in touch with.  It is an OH property. 

Appreciate all your help. 

Regards, 

Thanks.
