Welcome to Marietta. The first thing to know is whether your new home is inside the city limits. A Marietta mailing address does not settle it, and the answer decides your power company, your trash service, your school district and your tax bills. Look up the address on the city’s property search tool, or on Cobb County’s qPublic site, where a tax district of “(4) MARIETTA” means the city.

Power, water and sewer
Marietta Power and Water, the city’s utility, provides electricity and water and sewer service. Start or stop service in person at 675 N. Marietta Parkway, by phone at 770-794-5150, or with the city’s online stop-service form. The city asks for at least 24 business hours’ notice and may require a deposit. Details are on the Start or Stop Your Service page.
Some Marietta-area addresses get electricity from Georgia Power or Cobb EMC instead; the seller or landlord can tell you which. See our power outages guide for each utility’s outage line.
Natural gas: Georgia’s marketer system
Georgia opened natural gas sales to competition under a 1997 state law, the Public Service Commission explains. In the Atlanta Gas Light area, two companies are involved:
- Atlanta Gas Light owns the pipes, reads the meter and delivers the gas to certified marketers, its website says. Call it about leaks, odors and emergencies: 877-427-4321.
- A certified marketer sells you the gas and sends your bill. Pick one from the commission’s list of approved natural gas marketers and compare them with its marketers’ price index and scorecard.
Atlanta Gas Light has a start, transfer or stop service page for new customers.
Internet
Two providers publish home internet service pages for Marietta:
- Xfinity (Comcast): Xfinity in Marietta
- AT&T: AT&T Home Internet in Marietta
Availability depends on the exact address. The FCC’s National Broadband Map lists every provider that reports service at your address, including wireless and satellite options.
Car tag, title and driver’s license
From the Cobb County Tax Commissioner’s new resident page:
- Within 30 days of moving: change your vehicle’s title, registration, plate and insurance to Georgia. Bring your Georgia driver’s license, Georgia insurance, a Georgia emissions inspection if required, and your out-of-state title (or a signed lienholder form T-17 with your out-of-state registration).
- Emissions: in Cobb County, gas-powered vehicles 3 to 24 years old under 8,500 pounds need an emissions inspection every year.
- Within 60 days of moving: transfer your driver’s license through the Georgia Department of Driver Services; see how to apply for a Georgia license. Moving within Georgia? Update your address within 60 days; the online address change is free once per license term.
The Tax Commissioner’s Motor Vehicle Division is at 770-528-8600.
Taxes and the homestead exemption
You will get two property tax bills: Cobb County’s, due Oct. 15, and the city’s, due Oct. 31. If you live in the home you bought, apply for the city’s homestead exemption and the county’s separately, by April 1. Our property tax guide has the forms, rates and the appeal window.
