Yes, review is likely required if your project is being funded by a grant awarded by our office; you are using or intend to use rehabilitation tax credits; or you are receiving funding, licensing or need a permit from another federal or state agency. Email the Indiana DNR Division of Historic Preservation & Archaeology at dhpa@dnr.IN.gov for guidance.
If you are using private funds, you DO NOT need approval from the DHPA, even if the property is listed in the National Register of Historic Places.
Additionally, it is always a good idea to check at your city/town level in case there are local historic districts/commissions that require approval before alterations can be made to historic properties.
