1. No schoolhouse shall hereafter be erected, purchased, repaired, enlarged or remodeled nor shall the advertisement for bids for the execution of the plans and specifications for such schoolhouses be placed, in any school district except in a city school district in a city having seventy thousand inhabitants or more, at an expense which shall exceed one hundred thousand dollars, until the plans and specifications shall have been submitted to the commissioner of education and his approval endorsed thereon. Such plans and specifications shall show in detail the ventilation, heating and lighting of such buildings.
In the case of a school district in a city having seventy thousand inhabitants or more, all the provisions previously set forth in this subdivision shall apply, except that the commissioner may waive the requirement for submission of plans and specifications and substitute therefor the requirement for submission of an outline of such plans and specifications for his review. Such outline shall be in a form which he may prescribe from time to time.
In either case, the commissioner may, in his discretion, review plans and specifications for projects estimated at an expense of less than one hundred thousand dollars.
In the case of a school district in a city having a million inhabitants or more, all of the provisions previously set forth in this subdivision shall apply, except that such school district shall only be required to submit an outline of the plans and specifications to the commissioner of education for his information where a schoolhouse is to be erected in conjunction with the development of a project to be developed under the provisions of article two or five of the private housing finance law and where both the school and the project are to have rights or interests in the same land, regardless of the similarity or equality thereof, including fee interests, easements, space rights or other rights or interests.
