What listing means for this property

This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).

General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
