Cowen, Stephen D., House

Why it's listed
Built around 1854 on Cowan Road in Acworth, this two-story frame house was the home of Stephen D. Cowen, a yeoman farmer who moved from Jackson County, Georgia, and eventually held a farm of nearly 600 acres. It follows the plantation plain form, a variation of the I-house, with a two-story main block, a central hall, four principal rooms, and a shed-roofed rear ell. Classical Revival details include corner boards, a wide entablature and a double-leaf entrance with sidelights and transom. A one-story rear ell with kitchen and dining room was added about 1900. The house retains its hewn, braced frame, weatherboard siding and plain interior finishes. Such houses were built in Georgia mostly between 1820 and 1850, and few survive near Atlanta. The surrounding farmland and outbuildings have been lost to development, leaving 2.62 acres. The house is being rehabilitated as a welcome center and museum.
Significance in brief: The nomination argues the house is an excellent example of a pre-Civil War plantation plain-type house that retains its historic design, craftsmanship and materials. Few antebellum plantation plains survive in the growing metropolitan Atlanta region, and this one has a high level of integrity. Significance is local and rests on architecture alone.

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.
