Ohio Historic Site Preservation Advisory Board

The 17-member State Historic Site Preservation Advisory Board is appointed by the governor to advise the State Historic Preservation Officer and the Ohio History Connection Board of Trustees on historic preservation issues. ​

​The Advisory Board holds four meetings each year to recommend Ohio properties for nomination to the National Register of Historic Places.​

​Board recommendations can include approval with no additional recommendations or changes, approval with additional recommendations, not approved or tabled. Expectations for the outcome of the board's decisions can be seen in the nomination flow chart.

Listing in the National Register of Historic Places

Following the advisory board meeting, the State Historic Preservation Office staff will work with nomination authors to make any necessary edits before it is transmitted to the National Park Service in Washington D.C. final approval. ​

​Upon receipt, the National Park Service will begin its 45-day review period. If the National Register of Historic Places staff approves the nomination, the property is officially listed in the National Register of Historic Places. ​

​SHPO is notified of weekly listings and then notifies, by letter, property owners and interested parties of the listing.
