Why it's listed
Orange Hall is a gray frame house at 311 Osborne Street in St. Marys, Georgia, built in the Greek Revival style as a Doric temple. Two stories and five bays wide, it rises from a stuccoed brick daylight basement. A portico with four widely spaced fluted Doric columns and a low pedimented gable marks the front, and a central stair leads up to a pilaster-framed entrance with transom and sidelights. Inside, a four-room central hall plan includes doors and windows with carved corner medallions showing magnolia-like flowers. Oral tradition dates the house to the 1820s and links it to the Horace Pratt family, but deed and tax records point to James M. Smith building it between 1846 and 1853, possibly incorporating an earlier structure. The name comes from the hedges and avenues of sour orange trees that once surrounded the lot. Privately owned until 1960, it was then deeded to the city and now serves as a library and civic center.
Significance in brief: The nomination presents it as a fine example of raised Greek Revival architecture, with a Doric prostyle temple form and sophisticated proportion and scale. It also examines deed and tax records to date the house, which oral tradition places in the 1820s. The records suggest James M. Smith built the present structure, perhaps incorporating an earlier Pratt-era building.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
