How do I legalize my basement apartment in Marietta?

Legalizing a Marietta basement apartment means bringing the space up to code for a legal living unit, which typically includes proper egress, adequate ceiling height and separated electrical and plumbing systems, then pulling the permits the city or Cobb County requires for that use. Start by contacting the local building department to confirm what your specific basement currently lacks. A licensed contractor familiar with Marietta's permitting process can then scope the actual work and cost involved.
