Through the Agricultural Structures Preservation Easement, the preservation of historic barns and other agricultural buildings over 75 years old, is encouraged by granting property tax relief within a range of a 25-75% reduction in the structure' s assessment, to owners who (a) can demonstrate the public benefit of preserving their barns or other historic farm buildings, and (b) agree to maintain their structures throughout the minimum 10-year preservation easement. Also, maintaining and repairing the building will not result in an increase of its full assessed value for property tax purposes while under this easement. This application, PA 36-A, is available on the State of NH website for Assessing Forms. The deadline is April 15.
