Ohio Historic Inventory

The Ohio Historic Inventory was created in 1973 to provide an accurate continuing record of the historic architectural resources in the state of Ohio, with the Ohio Historic Inventory form as the tool to document the resources. The Ohio Historic Inventory form was developed to specifically gather sufficient information to reflect the architecture, historical significance, and integrity of the property.

Today Ohio Historic Inventory forms are completed electronically with an Internet-based application called I-Form. The use of I-form is expected by all professionals submitting inventory forms for compliance-related projects and all surveys funded, partially funded or initiated through the State Historic Preservation Office. Non-professionals must contact the Survey and National Register Manager at: SNROHPO@ohiohistory.org for alternative means of completing an Ohio Historic Inventory form.

I-Form: Online Inventory Data Submission App

I-Form is an Internet-based application that allows for electronic completion and submission of Ohio Archaeological Inventory forms. I-Form use is expected by professionals submitting inventory forms for most Section 106 compliance projects and surveys funded with Certified Local Government grants.
