Langdon House
Why it's listed
Built in 1855 in the old village of Columbia, the Langdon House at 3626 Eastern Avenue in Cincinnati is a frame building with vertical board and batten siding. Its style is described as "American" or "Steamboat" Gothic, though the ornate gingerbread trim that once decorated it has been removed. The house was listed largely for this architecture, since it is one of a very few Steamboat Gothic buildings remaining in a large Ohio city. It also carries a personal history. Its owner, Henry Archer Langdon, served with the 79th Regiment, Ohio Volunteer Infantry, from April 1862 to May 1865 and was with General Sherman in the campaign through Georgia. After the war he returned to Columbia and practiced medicine at this address until his death in 1876. At the time of the nomination the building was in fair condition, was owned by a preservation association, and was slated for restoration.
Significance in brief: The house is noteworthy for its "American" or "Steamboat" Gothic style and is described as one of a very few of that style remaining in a large Ohio city. It is also associated with Dr. Henry Archer Langdon, a Civil War surgeon who later practiced medicine at this address until his death in 1876.

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.
