Cost of Living Guide · Decatur, GA
The City of Decatur is small, close-in, and intensely walkable — a courthouse square ringed by restaurants, its own top-rated school system, and MARTA rail to downtown Atlanta. That combination commands premium prices in a compact footprint. Here's the verified cost picture.
Quick answer
Decatur is an expensive place to live for its size. The median household income is about $139,400 and the median home value is around $701,000 (U.S. Census/ACS) — high for a small city, because walkability, MARTA rail, and the independent city school system are in heavy demand. The combined sales tax is 8% and Georgia's flat state income tax is 4.99% for 2026.
Yes — on a per-home basis Decatur is one of the pricier places inside the Perimeter. It's a small incorporated city (not to be confused with the larger unincorporated "Decatur" DeKalb area), and buyers pay a premium for three things it does unusually well: a genuinely walkable downtown, direct MARTA rail access, and the independent City Schools of Decatur. Homes are often modest in size but command high prices for the location and lifestyle.
The Census-reported median home value is about $701,000. Housing is dominated by bungalows and older single-family homes in walkable neighborhoods like Oakhurst and Winnona Park, plus newer condos and townhomes around the square. Lot sizes and square footage tend to be smaller than in the outer suburbs, so you're paying for location and walkability rather than space.
Electricity is provided by Georgia Power; water and sewer through the City of Decatur / DeKalb County; natural gas on the Atlanta Gas Light network via competing marketers. Smaller, older homes can mean lower cooling loads than large suburban houses, though summer air-conditioning is still the main seasonal cost. Set utilities to start on your move-in date.
Decatur is one of the most transit-friendly and walkable suburbs in the region. MARTA rail serves the city on the Blue Line, with the Decatur station right beneath the downtown square plus Avondale and East Lake stations nearby — a direct ride to downtown Atlanta and connections to the airport. Many errands are walkable, and cycling is common. Main roads include Ponce de Leon Avenue, Church Street, Clairemont Avenue, and College Avenue.
Decatur runs its own independent district, City Schools of Decatur (CSD) — separate from the DeKalb County School District — centered on Decatur High School. The CSD reputation is one of the single biggest drivers of home demand and prices inside the city limits, so confirm that an address is in the City of Decatur (and CSD) rather than unincorporated DeKalb when comparing.
Narrow historic streets, on-street parking, and older homes with stairs mean truck staging and carry paths matter; condos near the square may require freight-elevator and COI arrangements. Month-end is the busiest window.
