Financial Incentives for Historic Designation

Press Enter to show all options, press Tab go to next option

Historic buildings are tangible links with the past. They help give a community a sense of identity, stability and orientation. The Federal government encourages the preservation of historic buildings through various means. One of these is the program of Federal tax incentives to support the rehabilitation of historic and older buildings. The Federal Historic Preservation Tax Incentives program is one of the Federal government's most successful and cost-effective community revitalization programs. The Preservation Tax Incentives reward private investment in rehabilitating historic properties such as offices, rental housing and retail stores.
