Best New Resident Guides in Marietta, GA (2026)
Last updated: May 2026
Marietta is Cobb County's largest city and one of North Atlanta's most historically rich communities — a vibrant downtown square, excellent schools, and a range of neighborhoods from newer subdivisions to historic homes. Utility setup here has one major difference from the rest of our market: Marietta has its own municipal electric and water utility, Marietta Power and Water. You don't set up Georgia Power for electricity or Cobb County Water for water — you set up Marietta Power for both. For gas, Atlanta Gas Light handles delivery. Internet is still your first booking priority.
