Who handles building permits in Marietta?

It depends on where the home is. Cities such as Powder Springs and Acworth run their own building departments. For unincorporated Cobb County, Cobb County's Residential Permitting office handles residential permits at (770) 528-2060, and finish work like painting, tiling, cabinets and countertops doesn't need one. Check with your city or county before work starts.
