Peachtree Corners' housing stock reflects its evolution from a quiet riverside crossroads into an established Atlanta suburb. The city contains a mix of single-family homes built primarily from the 1970s onward, as neighborhoods were developed to serve the growing Technology Park workforce and expanding families. Subdivisions span a range of styles, from traditional two-story homes to larger estate properties in communities such as the Country Club of the South, a golf-and-country-club neighborhood. The Town Center adds attached townhomes and mixed-use living, offering lower-maintenance options within walking distance of shops and restaurants. Because the city was incorporated relatively recently, its neighborhoods were largely built out under Gwinnett County's planning, resulting in mature, tree-lined streets and well-established community infrastructure. Buyers drawn to Peachtree Corners tend to value the combination of larger homes, strong school clusters, and proximity to both the river and major employment centers.

Peachtree Corners is made up of several well-known residential neighborhoods that give the city its distinct character. The Country Club of the South is among the most prominent, a gated golf community with estate homes and its own country-club amenities. Neely Farm and Rivermont are established swim-and-tennis communities popular with families, while Winters Chapel and North Doraville reflect the city's more accessible, long-settled corridors. The Town Center district adds a denser, more walkable layer, with townhomes and residences clustered around the Town Green and its shops and restaurants. Riverfront areas near Jones Bridge Park and the Chattahoochee offer a quieter, nature-oriented setting. Together, these neighborhoods give buyers a broad range — from golf and tennis communities to mixed-use urban living — while remaining within a single, well-regarded school district.

Peachtree Corners combines suburban living with a genuine downtown gathering place. The 21-acre Town Center is the community's social heart, with more than a dozen restaurants, retail shops, a co-working space, and a two-acre Town Green that hosts a summer concert series and other events throughout the year. This gives residents a walkable destination that many Atlanta suburbs lack. The Chattahoochee River shapes the city's recreational culture, offering kayaking, fly fishing, and tubing along its quiet stretches. The annual Art on the Chattahoochee event, held at Jones Bridge Park, celebrates the riverfront setting and draws visitors from across the region. The city's technology-oriented heritage also lends a forward-looking, professional character, with corporate campuses and innovation activity woven into the local identity.

Peachtree Corners is served by Gwinnett County Public Schools, one of Georgia's largest school districts. The city is notable for its STEM education footprint: Paul Duke STEM High School, located within Technology Park, opened in 2018 as a dedicated science, technology, engineering, and math campus. Other district options in the area include the Gwinnett School of Mathematics, Science, and Technology and McClure Health Science High School. Private and parochial options are also present, including Wesleyan School, a well-established K-12 institution, and Cornerstone Christian Academy, a K-8 school. The combination of strong public clusters, specialized STEM academies, and private schools gives families in Peachtree Corners a wide range of educational choices, a key factor in the city's appeal to relocating families.

Peachtree Corners sits along major transportation corridors in the northern Atlanta suburbs. Interstate 85 runs nearby, providing the primary highway route toward downtown Atlanta and the wider metro, while State Route 141 (Peachtree Industrial Boulevard and Peachtree Parkway) threads through the city and connects it to Dunwoody, Norcross, and surrounding Gwinnett communities. The city's position in Gwinnett County places it within reach of several of metro Atlanta's employment hubs, and commuters use a network of interstates and state highways for daily travel. For air travel, Hartsfield-Jackson Atlanta International Airport is accessible by highway. While the city is primarily car-oriented, Gwinnett County Transit provides local and commuter bus service connecting the area to the region.

The Chattahoochee River is Peachtree Corners' defining recreational asset. Jones Bridge Park provides river access for fishing, picnicking, and launching kayaks or tubes, while the Chattahoochee River National Recreation Area offers hiking and biking trails with views of the river and surrounding forest. Trout fishing and quiet paddling are popular along the city's riverfront stretches. Within the city, the Town Green hosts concerts and community gatherings, and the annual Art on the Chattahoochee festival celebrates the riverfront setting. Parks across the city provide playgrounds, sports fields, and green space, and residents benefit from Gwinnett County's extensive park system. The blend of river recreation, community events, and well-maintained parks gives Peachtree Corners an active, outdoors-oriented lifestyle within the metro area.
