Using fully finished basement as "Duplex with separate entrance"?

[Daniel C.]

I'm looking for some input.  The property is around Cypress Hills near East NY which are supposed to an up and coming Brooklyn neighborhoods.  It is a legal 2 family with two apartments and a fully finished basement.  The basement is essentially an apartment -- two means of egress, a bathroom, kitchen cabinets and sink but minus the stove and fridge.  While I do see the potential benefit of marketing it to renters as a possible "duplex with separate entrances" or an apartment with extra rec room / storage space, I'm concerned with possible C of O issues.  

As long as a stove and fridge are not placed in the basement, is that ok?

Could a microwave and mini fridge be used in the basement without issues?

If anyone has experience with such setups - particularly NYC BPers as laws may be different in other states.  Please let me know if it's a good idea; or a potential major headache.  Does anyone have creative suggestions on how to make this work?   Please let me know.  Feel free to PM me.  Thank you.
