N.Y. Lab. Law § 471
The board of standards and appeals shall make rules to carry out the provisions of this article. Such rules shall be the minimum standard required and shall supersede any special law or local ordinance inconsistent therewith, and no local ordinance inconsistent therewith shall be adopted, but nothing herein contained shall prevent the enactment by local ordinance of additional requirements and restrictions. Such rules of the board of standards and appeals for the construction, equipment and maintenance of places of public assembly, shall be subject to the procedure set forth in sections twenty-nine and thirty of this chapter, may be limited in their application to certain classes of buildings or to the conditions under which they are operated, and some or all of them may apply only to those buildings or places to be constructed, maintained or conducted in the future. Such rules shall have the force and effect of law and be enforced in the same manner as the provisions of this chapter.
