The Lithonia Historic District consists of a commercial core surrounded by residential areas, with a period of significance spanning from 1845 to 1964. Stylistic influences in the district include Second Empire, Queen Anne, Folk Victorian, Neoclassical Revival, English Vernacular Revival, Craftsman, and Colonial Revival. The district is bisected by the Georgia/CSX Railroad, which runs perpendicular to the historic commercial core's primary thoroughfare, Main Street. The commercial area extends south from the intersection of Main Street and the railroad, covering a two-block area. The commercial buildings are primarily brick and local granite masonry, with little decorative detailing. Commercial styles include single retail, multiple retail, and retail and office types. Within the historic district, there is some non-historic infill construction such as the 1968 Lithonia Plaza shopping center. The residential areas contain architecture typical of late 19th- to mid 20th-century types and styles. Residential neighborhoods also feature locally quarried granite and gneiss. House types and styles include the central hall Georgian cottage, gabled-wing cottage, Queen Anne cottage, New South cottage,
pyramidal cottage, bungalow, Ranch house, I-House and Queen Anne house. Landmark properties include the Masonic Lodge (1916), The Lithonia Women's Club (1928), the Lithonia First United Methodist Church (1910), Antioch Baptist Church (1911), Lithonia Presbyterian Church, The Union Missionary Church (1911), the Bruce Street equalization school (c.1953), and
The Seminary (1895). Contributing sites in the district include two cemeteries, two parks, the former Georgia Railroad Quarry, and the ruins of the Bruce Street School for African-Americans (1938). The district is significant under
National Register criterion A (association with historic events) and C (architecture), with areas of significance in Architecture, Black and European Ethnic Heritage, Community Planning and Development, Industry, and Transportation. ==Demographics==
