Conversion from 2 fam to 3 fam in Newark NJ

[Eric Panecki]

Looking at buying a legal 2 family in North Newark NJ. The property is 3 stories, top 2 are one unit and bottom is a separate. It is set up in a way it could easily be converted to a 3 family. I know by converting it becomes a density issue and will need to get the zoning board involved. The street has multiple 3-4 fam dwellings.  Has anyone done this and how difficult is it to get approvals?
