Grantville's housing reflects its small-town, historic character. The stock includes older homes near the downtown historic district, many dating from the late 19th and early 20th centuries, along with mid-century houses and newer construction on the town's edges. Homes tend to be modest in scale and affordable by metro Atlanta standards, and the surrounding rural areas of Coweta County offer larger lots and acreage. The city's growth, driven by proximity to Atlanta, has brought some new development while the historic core retains its character. Buyers are typically families and residents seeking an affordable small-town setting with historic charm and convenient access to Newnan and Atlanta.

Grantville is organized around its historic downtown, a designated National Register district of more than 200 contributing buildings centered along the railroad corridor. The downtown's one- and two-story brick commercial structures and adjacent homes preserve the scale of the late-19th and early-20th-century town. Residential streets radiate from the center, mixing older historic houses with mid-century and newer homes, and transition quickly into the surrounding farmland and rural subdivisions of Coweta County. The city does not have large master-planned developments; instead, its neighborhoods reflect generations of growth around the railroad and the U.S. Highway 29 corridor, giving the community a cohesive, rooted feel.

Grantville offers a quiet, small-town Southern lifestyle with a strong sense of history. The city's preserved downtown — with its brick storefronts and railroad-era architecture — is a point of community pride and a reminder of the town's cotton and rail heritage. Daily life centers on local schools, churches, and community events, with a pace that remains unhurried despite the town's growth. The historic setting has made Grantville a favored filming location, adding a touch of regional renown. Newnan, the Coweta County seat, provides larger shopping, dining, and services a short drive away, while Atlanta and its amenities are within commuting range along the Interstate 85 corridor.

Public education in Grantville is provided by the Coweta County School System, which operates Glanton Elementary School within the city. Students attend other schools in the district for middle and high school, with assignments varying by attendance zone, and families commonly confirm placements through the district. The district's schools are a central part of community life, and its reputation is a factor in the area's family appeal. In addition to the public system, the broader Coweta County and metro Atlanta region offer a range of private and charter options, and higher-education institutions in the area include the University of West Georgia and Atlanta-area colleges.

Grantville is situated along U.S. Highway 29, the historic corridor connecting it to Newnan and points southwest, and lies within reach of Interstate 85, the principal highway linking Atlanta with the Alabama border and the broader Southeast. This positioning makes commuting to Newnan, LaGrange, and the Atlanta metropolitan area practical, while the city itself remains quiet and small-scale. Personal vehicles are the primary means of travel, consistent with the rural-suburban character of west Georgia. Regional air travel is available through Hartsfield-Jackson Atlanta International Airport, roughly an hour's drive to the northeast along the interstate corridor.

Recreation in Grantville is centered on its historic downtown and the surrounding west Georgia landscape. The Grantville Historic District offers a walkable setting for exploring the town's railroad-era architecture, and the city's place on the West Georgia Textile Heritage Trail connects it to the region's industrial history. Community parks, ball fields, and school facilities provide local recreation, while the rural roads and countryside of Coweta County support outdoor activities. The nearby Chattahoochee River and the parks and trails of the broader west Georgia region extend the options, and Newnan and Atlanta provide larger recreational and cultural amenities within a short drive.
