What other factors might affect project eligibility?

Answer
Certain factors and conditions can determine whether a potential project is eligible for the 20% tax credit.

Physical Integrity
The 20% tax credit for historic preservation is meant to preserve historic buildings, and not to create buildings that look old, but that are in effect new buildings. Thus, the Preservation Tax Incentives are not available where there is insufficient historic material to preserve at the outset of the rehabilitation. Once the integrity of a building has been lost due to deterioration, damage, or previous alterations, it can never be regained. While new material can exactly copy significant features, material integrity itself can never be re-created. It is important to select a building for rehabilitation that retains its basic physical integrity before rehabilitation.

Non-historic Surface Coverings
Some historic buildings have been covered with non-historic surface coverings that obscure the building underneath. In these cases, it may be necessary to remove the covering to make sure that there is enough historic building material remaining that the building still qualifies as historic.

Multiple Buildings
Farms, mills, and other historic properties often have more than one building. For properties with multiple buildings that were functionally related historically, the rehabilitation certification decision will be based on the effect of the overall rehabilitation on the entire property, and not on each structure or individual component.

Moved Buildings
Moving a historic building can jeopardize its listing in the National Register of Historic Places, and special procedures must be followed to ensure its continued listing. Likewise, moving a building into or within a historic district may jeopardize its ability to contribute to the significance of the district. If a building will be moved as part of the rehabilitation project, consult with the SHPO as soon as possible.

Demolition
Projects that involve demolition require careful planning to ensure approval. This is true whether whole buildings will be demolished or only parts of a structure.
