New York adopted a law in July that provides for local implementation of tax exemptions for improvements to property, in excess of ten thousand dollars, that obtain LEED(R) certification or meet a similar standard, based upon adoption of a local law implementing such a provision. To be eligible the construction must commence in or after January 2013 and the Statute provides for exemption, on a sliding scale, over ten years.
Chapter 188 of the Laws of 2012, which is the new section 470 of the New York Real Property Tax Law reads:
     ยง 470. Exemption for improvements to  real  property  meeting  certif-
   ication  standards for green buildings.  1. Construction of improvements    to real property initiated on or after the first  day  of  January,  two    thousand thirteen, meeting LEED certification standards for green build-
   ings  as provided in this section, the green building initiative’s green    globes rating system, the  American  National  Standards  Institute,  or    substantially  equivalent  standards  for  certification using a similar    program for green buildings as determined by the municipal  corporation,
   shall be exempt from taxation by any municipal corporation in which such    property is located to the extent provided in this section, provided the    governing board of such municipal corporation, after conducting a public    hearing, adopts a local law, ordinance or resolution providing therefor.
     2.  Such real property, or portion thereof, which is certified under a    LEED certification standard for the  categories  of  certified,  silver,
   gold or platinum as meeting green building standards, as determined by a    LEED  accredited  professional shall be exempt as provided below for the    respective percentages provided that a copy of  the  LEED  certification    for  a  qualified  category  is  filed with the assessor’s office and is    approved by the assessor as meeting the requirements of this section and    the municipal corporation’s local law, ordinance or  resolution.    Such    exemption  shall  be  to  the  extent  of any increase in assessed value    resulting from the construction or reconstruction of a property  meeting    LEED certification.

     3. No such exemption shall be granted unless: (a) such construction of    improvements  was  commenced  on  or after the first day of January, two    thousand thirteen, or such later date as may be specified by local  law;
   (b)  the  value  of  such  construction  exceeds the sum of ten thousand    dollars;  and  (c) such construction is documented by a building permit,
   if required, for the improvements, or other appropriate documentation as    required by  the  assessor.  For  purposes  of  this  section  the  term    “construction  of  improvements”  shall not include ordinary maintenance    and repairs.
     4. If the assessor is satisfied that the applicant is entitled  to  an    exemption pursuant to this section, he or she shall approve the applica-
   tion  and such real property shall thereafter be exempt from taxation by    the municipal corporation as provided in this  section  commencing  with    the assessment roll prepared after the taxable status date. The assessed    value of any exemption granted pursuant to this section shall be entered    by  the  assessor on the assessment roll with the taxable property, with    the amount of the exemption shown in a separate column.
