Where Is Decatur in Relation to Atlanta?

If you’re standing in Downtown Atlanta, Decatur is:

  • About a 10–15 minute drive east via I-20 or Ponce de Leon Avenue

Decatur’s traditional city center is the Decatur Square, near:

  • City of Decatur City Hall – 509 N. McDonough St, Decatur, GA 30030
  • Decatur MARTA Station – directly under the square

If you think in terms of intown neighborhoods:

  • To the west of Decatur: Druid Hills, Candler Park, and Inman Park heading toward Atlanta
  • To the east and south: unincorporated DeKalb communities like Panthersville and Belvedere Park
  • To the north: neighborhoods and cities like North Decatur and North Druid Hills

For locals, Atlanta and Decatur feel like they run together, but city limits matter for things like taxes, schools, and city services.

“Decatur, GA” vs. “Atlanta, GA” on Addresses

One source of confusion: many people in the Decatur area have a “Decatur, GA” mailing address but do not actually live in the City of Decatur.

There are three main categories:

  1. City of Atlanta

    • Address will usually say Atlanta, GA
    • You’re under City of Atlanta government, police, zoning, and Atlanta Public Schools (APS), if zoned for APS.
  2. City of Decatur

    • Address will say Decatur, GA 30030 (most commonly, though not exclusively)
    • You’re under City of Decatur government, Decatur Police, City Schools of Decatur, and Decatur property taxes.
  3. Unincorporated or Other Cities in DeKalb County with “Decatur” mailing addresses

    • Address can say Decatur, GA, but you may live in unincorporated DeKalb County or another municipality.
    • You’re under DeKalb County for many services, not the City of Decatur.
    • School zoning and taxes follow DeKalb County lines, not just the ZIP.

👉 Practical tip:
If you’re unsure whether an address is in Atlanta, Decatur, or just has a Decatur mailing label, you can:

  • Check the county tax assessor:
    • Fulton County Tax Assessor (for most of Atlanta)
    • DeKalb County Tax Commissioner (for Decatur and east Atlanta areas)
  • Look at your property tax bill or utility bill for the city name.
