Property use requirements:
In order for a structure to be considered an historic barn eligible for this exemption, the structure must have been at least partially constructed prior to 1936, and must have been originally designed and used for storing farm equipment or agricultural products, or for housing livestock. An otherwise qualified barn may not receive this exemption if:
- it received an exemption as an agricultural building exemption (RPTL §483) within ten years of the date of the application for the exemption for an historic barn;
- it is used for residential purposes; or
- its historic appearance has been materially altered by the reconstruction and rehabilitation.
Certification by state or local government:
Required construction start date or other time requirement:
Reconstruction or rehabilitation must have commenced after the effective date of the local law or resolution adopting this exemption (see Local Option below), unless such local law or resolution provides that reconstruction or rehabilitation which commenced prior to the effective date of the enabling legislation may qualify for the exemption.
Yes. Each county, city, town, village and school district may choose whether or not to allow the exemption. The option must be exercised by a county, city, town, or village through adoption of a local law and by a school district through adoption of a resolution. In all cases, a public hearing must be held prior to adoption of the local law or resolution.

Calculation of exemption
General municipal and school district taxes:
The following percentages of the increase in assessed value attributable to the reconstruction or rehabilitation should be applied:
|Year of exemption||Percentage of exemption|
For this exemption the exempt amount for each year is to be calculated on the basis of the exemption base," defined as the increase in assessed value in the first year of the 10-year period, unless there has occurred in any year a change in level of assessment of 15% or more for a final assessment roll, in which case the exemption base must be adjusted by the fraction resulting from dividing the total assessed value of the parcel on that final roll (after accounting for any physical or quantity changes since the prior roll) by the total assessed value on the immediately preceding assessment roll. See Reporting requirements (assessor) below.
Special ad valorem levies and special assessments:
No exemption allowed.
