3rd Floor Unit in 2F Zoning in Albany

[Jonathan Golon]

I am looking to purchase a property that has a 3rd unit that doesn't appear to have been used in several years, but everything is there to make it legal (from what I can see). It is zoned as a 2 family (along with the rest of the neighborhood). From what I understand, its almost impossible to get a 3rd unit legalized in 2F zoning areas, but considering this has had the 3rd unit there for many years (appliances look 30+ years old), is there any chance it would be allowed?

If not, what are the thoughts on using it as a 3rd unit, but only renting to family and friends?
