At Austell's City Hall, residents can attend city council meetings, which are held on the first Monday of every month at 7pm. At this location, residents can pay their city taxes, city water and sewer bills and utilize the city police department services. The finance department, notary public and sanitation department can be found here as well. All other Austell government departments and services will be found at the Threadmill Complex at 5000 Austell-Powder Springs Road.
The city clerk, the municipal court, the community affairs and public works departments can all be found at Austell's historic Threadmill complex. The facility, once a thread mill, was renovated in 2001 for government offices and private businesses.
Austell city mayor's office, the sheriff's office and the office of the Cobb County commissioner for Austell's district are also located at the complex. The North Georgia Law Enforcement Academy also is a tenant at the complex, which is owned by the city of Austell.
The Sweetwater Valley branch of the Cobb County Public Library System has a long history. It began in 1913 when the Austell Women's Club made a circulating library one of its first priorites. In 2003, the library branch moved to a new location in the Austell City Threadmill Complex after having been in a log cabin and then a 1950s building on Front St. The 3,000-square-foot space houses a large collection of books as well as 15 computers for public access.
