Basement conversion in Providence possible?

[Anthony Britto]

Hello I’m looking for information regarding turning an unfinished basement to a legal apartment in a current 2 family. I am in an R3 zone so I am under the impression I have the ability to do so. My issue is not knowing who to talk to to make sure everything is legal or making a plan to apply for new zoning. I do have 2 exits as it a walkout basement and the ceiling is 7 ft high. I guess my other understanding is that I have to provide it is water proof and it is correctly zone for fire. I am also confused about the general laws on the windows. Is this type of work even possible to the point it’s worth looking into? I know the city probably isn’t a fan of basement apartments. 
thanks
