The Office of Archaeology and Historic Preservation offers a variety of data access services, as well as permitting and curation services. Services are offered at cost to qualified researchers. If you are a homeowner or an academic researcher, you may be eligible for a fee reduction. See our Billing Policies & Fee Structure for more information.
Please note: As of July 1, 2024, all data access service requests must be submitted via the online Data Access Request Form (DARF). Previous PDF and hard copy versions of request forms, as well as requests made via phone, fax, or email will not be accepted. Please direct questions to hc_filesearch@state.co.us.
