Rent by the Room and Occupancy Limits

[Joseph Ayoub]

Hi All - I am wondering if anyone who does rent by the room in the Atlanta metro area has advice on how to do a rent by the room rental? Specifically, how to go about managing unrelated persons living together per county or city ordinance and lease structure. 

I am considering two properties: 

1) A home DeKalb County (Decatur) that is zone R75 for single family zoning. The zoning record says it is in an unincorporated tax district. 

2) A home in Kennesaw that is also zoned for single family.

I see online that there is conflicting info, where in DeKalb county, 3 unrelated people can live together, but Decatur shows 2 unrelated people. Additionally, the house in Kennesaw is close to KSU and currently used as a student rental, but Cobb county shows 2 unrelated people who can live with each other. 

My questions are:

1) How are leases structured? Do you create a separate lease for each individual?

2) Do you need a rental license or any registration with the county/city?

3) Is rent by the room a feasible strategy with these county/city living restrictions?

Thanks for any insight!
