Georgia Power and Atlanta Gas Light — separate utilities for Sandy Springs
Georgia Power (electricity) and Atlanta Gas Light (AGL, natural gas) serve Sandy Springs as two separate regulated utilities, both subsidiaries of Southern Company, both regulated by the Georgia Public Service Commission. Georgia Power is one of the largest electric utilities in the Southeast, serving approximately 2.7 million customers across much of Georgia. For electrical service changes, panel upgrades, meter installations, and solar net metering interconnection: contact Georgia Power through georgipower.com. Atlanta Gas Light is Georgia's largest natural gas distribution company, serving approximately 1.7 million customers including all of metro Atlanta. For new gas service, gas line modifications, and gas service changes: contact AGL through atlantagaslight.com alongside the Sandy Springs Building Division permit.
Unlike some markets in this guide where a single utility provides both electric and gas (Eversource in Waterbury CT, WPS in Green Bay WI), Sandy Springs requires homeowners to coordinate with two separate companies for energy service changes. Call 811 before any excavation to locate both Georgia Power electric infrastructure and AGL natural gas infrastructure, plus City of Sandy Springs water and sewer lines.

Sandy Springs in metro Atlanta — understanding this city’s residential character
Sandy Springs, incorporated in 2005, has grown into one of metro Atlanta's premier residential and corporate communities. The city's approximately 110,000 residents live in a mix of housing types that directly affects renovation planning: older single-family neighborhoods in Sandy Springs' eastern areas (many built in the 1960s through 1980s) often have crawl space foundations reflecting traditional Southeast construction practices. These homes may also have older mechanical systems, galvanized plumbing (in the oldest homes), and classic Atlanta-area ranch and Colonial architectural styles. Newer developments from the 1990s onward, particularly in the northern and western parts of Sandy Springs, were predominantly built on slab-on-grade foundations following a shift in builder practices toward slab construction in the Atlanta market.
Sandy Springs' terrain differs significantly from most other cities in this guide. The rolling wooded hills of the Piedmont region create sloped lots that affect deck design, foundation costs for additions, drainage considerations, and solar panel shading. The Chattahoochee River's proximity in Sandy Springs' northwest section creates both environmental amenity and regulatory overlay requiring special consideration for projects near the river corridor. Contact Sandy Springs Community Development at (770) 730-5600 for questions about how your specific property's characteristics affect permit requirements.
