What is required for historic buildings?


Note:  The key point is not the age of the building, but whether it is registered or eligible to be registered and listed.  In the following cases, historic buildings are considered exempt from provisions of the energy code (however, we recommend always confirming with the state or local jurisdiction):

  • listed in the State or National Register of Historic Places;
  • designated as a historic property under local or state designation law or survey,
  • certified as a contributing resource with the National Register listed or locally designated historic district; or
  • with an opinion or certification that the property is eligible to be listed on the National or State Registers of Historic Places either individually or as a contributing building to a historic district by the State Historic Preservation Officer or the Keeper of the National Register of Historic Places.
