Enrollment on the National Register by itself does not impose any restriction on a property. However some restrictions may apply if a property received federal funds. Tax credits claimed may be refundable if the property is not maintained as historic for a number of years after the credit was received.
Federal Tax law support historic preservation in two important ways.
Second, for certain historically significant property that also can be depreciated, a tax credit in the amount of 20% of the costs of rehabilitation is available. This tax credit is generally not available to homeowners because of the requirement that the property can be depreciated, however, owners with rental property in the historic district may be able to claim the tax credit for rehabilitation projects. It is not enough that the property simply be in the Westmoreland Historic District, however presence in the district could go a long way towards demonstrating the historic significance of the property. More information on this 20% tax credit program can be found on the National Park Service website.
