How do I know if a Johns Creek two-family is legal?

A Johns Creek two-family home is legal only if the second unit was permitted through the city, which you can confirm by requesting the property's permit and certificate of occupancy history before you buy or list. A separate kitchen and entrance alone do not make a unit legal, and an unpermitted second unit can affect financing, insurance, and what an appraiser will credit toward value. Fulton County and city records both keep this history on file. Joel Boss checks Johns Creek permit records before writing an offer on a two-family.
