House had in law suite but not zoned for it

[Greg Behan]

Hi all, I am under contract and trying to figure out my layout for my next flip.  It's a late 70's bilevel and the top floor is 4 bedroom with a kitchen and bathroom and the downstairs is a 1 bedroom kitchen and bathroom in law suite.  The house was built this way but never had the zoning for it.  The township said they normally approve them for hardships which clearly isn't our case.  Is there a way to market it as an in law suite even though its not zoned for it?  Should I just turn it into a wet bar or bigger laundry room or something?  Should I try to get the zoning changed?
