About the Ohio Historic Inventory

What Is the Ohio Historic Inventory?
The inventory program was developed to serve as an accurate and continuing record of the architectural and historic properties currently existing in the state. The Ohio Historic Inventory is used to record basic information on historic properties in Ohio. Since 1974, over 95,000 historic properties have been entered into the records of the Ohio Historic Inventory.

Who Uses the Ohio Historic Inventory Form and What Is It Used For?
The Ohio Historic Inventory is used by the Ohio Historic Preservation Office staff, by various state, local, and federal agencies, and by the general public for making land-use planning, urban development, and road-improvement decisions. In addition, the inventory serves as an official archive and body of information for researchers and property owners.

How Is the Form Set Up?
The Ohio Historic Inventory Form consists of a single page, two-sided questionnaire that gives a complete but succinct description and history of a building, site, structure, or object. The form is divided into six basic categories: Identification, Location, Background, Architectural Data, Additional Information, and Photographic Documentation. The form is printed on archival paper.

Where Can I Get the Form?

What Does the Form Do?

  • The Ohio Historic Inventory form provides a brief description of the location, background,and architecture of a building, site, structure, or object of architectural or historical significance.
  • The Ohio Historic Inventory form is an important reference for organizing community preservation efforts and can be used as a guide for safeguarding the historical and architectural resources of Ohio.
  • The Ohio Historic Inventory form serves as an important data base for the Ohio Historic Preservation Office's computerization efforts.

What Doesn't the Form Do?

  • The Ohio Historic Inventory form does not automatically nominate or indicate acceptance of a property to the National Register of Historic Places, though it may serve to bring an eligible property to the attention of local and state governing bodies.
  • The Ohio Historic Inventory is not intended to be the complete story on a given property; it is an inventory. The pertinent information should be necessarily brief and condensed, hence the need for accurate and informative documentation.
  • The Ohio Historic Inventory is not a form of protection for a historic resource, nor does it provide property owners with a list of do's and don'ts.
