Multiple Dwelling Law Section 62
Parapets, guard railings and wires
1.Every open area of a roof, terrace, areaway, outside stair, stair landing, retaining wall or porch and every stair window of a multiple dwelling erected after April eighteenth, nineteen hundred twenty-nine, shall be protected in a manner approved by the department by a parapet wall or a guard railing three feet six inches or more in height above the level of such area, or, in the case of a stair window, above the level of the floor adjacent thereto, unless the department shall deem that such protection is not necessary for safety. In any multiple dwelling where a bulkhead door or scuttle cover opens within four feet of the edge of the roof, that part of the roof which is immediately adjacent to such door or cover shall be adequately protected. Such protection shall consist of guard rails or parapet walls extending at least three feet six inches above the level of the roof, and shall be arranged and placed in a manner approved by the department, but shall not be required for such bulkhead door or scuttle cover when the bulkhead or scuttle on such dwelling is immediately adjacent to, and also on the same level as or on a lower level than, the roof of a contiguous building. This subdivision shall not apply to the open area of a roof of a garden-type maisonette dwelling project.
2.All radio, antennae or other wires over any roof shall, unless otherwise permitted by the department, be kept ten feet or more above such roof, and no radio, television antennae or other wires shall be attached to any fire escape or to any soil or vent line extending above the roof.
