Restored historic and old buildings, particularly in cities like San Francisco, contribute to the distinctive character that lure tourists and thereby creates jobs. Two relatively recent changes affect those buildings and the potential for their continued revitalization. First, changes to the Historic Tax Credit may alter the capital stack used to finance the rehabilitation of historic projects, as well as the overall return on investment for such projects. Second, changes to the Standards for the Treatment of Historic Properties with Guidelines for Preserving, Rehabilitating, Restoring and Reconstructing Historic Buildings may alter how historic resources are treated and the mitigation measures required under the California Environmental Quality Act.
