National Register of Historic Places

Preliminary Opinion Request

In order to assess the eligibility of properties for the National Register of Historic Places, a certain amount of information is needed. The "Preliminary Opinion on Eligibility" provides the SHPO the baseline information needed to determine whether a property meets the basic National Register criteria. These criteria involve the age of the property (at least fifty years), its historic integrity, and its demonstration of significance in our history.

This initial step is designed to save you the time and expense involved in the preparation of an actual National Register nomination, should the resource not meet the criteria.
