How do I find out whether a Marietta basement apartment is legal before I buy?

Confirming a Marietta basement apartment's legal status starts with checking permit records at the county or city building department, since a space built or converted without permits may not be legally rentable or counted toward square footage regardless of how it looks or is marketed. A buyer's agent or attorney can pull that permit history before an offer is finalized. Joel Boss checks permit status on any Marietta property with a basement unit before a buyer counts on that space.
