Do I need a permit for a kitchen renovation in Marietta?

You do for anything structural, electrical or plumbing, which covers almost every full kitchen renovation. Replacing cabinets and countertops with no change to services usually does not require one. Moving a wall, adding circuits, relocating plumbing or changing the gas line all do. Budget two to four weeks for review in Cobb County and expect inspections at rough-in and at completion. Work done without a permit surfaces when you sell, and correcting it then costs more than the permit ever would have.
