Halsey Valley Grand Army of the Republic Meeting Hall
Also known as: Hagadorn G.A.R. Post--Sons of Union Veterans of the; Civil War Meeting Hall
Why it's listed
Built in 1894 in the rural hamlet of Halsey Valley, this two-and-one-half-story frame building served as the meeting hall of Hagadorn Post #505 of the Grand Army of the Republic, a Civil War veterans' organization, and the Sons of Veterans camp that helped build it. The post, formed in 1884, had previously rented rooms in local hotels. The hall keeps its original clapboard siding, two-over-two windows and main entrance doors, and electricity was the main addition, in 1937. Downstairs hangs a lithograph of Andersonville Prison. The second-floor auditorium retains beaded-board walls, a star-decorated ceiling, an altar table, officers' chairs, perimeter benches, and wall displays of portraits, maps, flags and photographs. Heated by stoves, it is still used by the Sons of Union Veterans and their Auxiliary. It is listed for its social history role and as a rare, highly intact example of a fraternal meeting hall.
Significance in brief: The hall is significant under Criterion A for its long association with the Grand Army of the Republic post and the Sons of Union Veterans camp that succeeded it. It is significant under Criterion C as an intact example of a fraternal hall building type. It is now a rare survivor of its kind, noted for an unusually high degree of architectural integrity, including a second-floor meeting room that remains as it was in 1894.

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.
