In 2010, the Philadelphia Historic Preservation Ordinance was amended to allow for the designation of significant public interior spaces to the Philadelphia Register.
Since that time, two such nominations have been approved by the Historical Commission: City Hall Council Chambers and the Family Court Building. Changes to the architectural fabric of these interiors are now regulated by the Philadelphia Historical Commission to ensure the preservation of their significant character.
Historic interiors eligible for nomination include any space originally designed to be publicly accessible, including municipal, commercial, and institutional properties. Residential properties are not eligible. The interior does not have to be publicly accessible at the time of designation and designation does not mandate public access.
