Statement of Basis and Purpose 

The Department of Buildings (DOB) is amending section 105-02 of Title 1 of the Rules of the City of New York relating to tax abatements for solar electric generating systems.  These amendments modify the prohibition of ballast for grade-level installations and clarify requirements of the New York City Building Code which apply to ballast systems.


The rule currently prohibits ballast at grade level, which is permitted by the Building Code.  The Code also prohibits the use of aggregate as ballast on roofs because New York City is in a hurricane zone.  The proposed amendments clarify the usage of ballast and aggregate.


DOB’s authority for this rule is found in Section 643 and 1043(a) of the New York City Charter and Title 4-C of Article 4 of the Real Property Tax Law of New York State.
