71. Chimneys of brick, stone, or other incombustible material, may be corbelled out in the upper storeys of build- ings, provided that the work so corbelled out does not project from the wall more than the thickness of such wall, but all chimneys built in the ground storeys of buildings shall, unless with the consent of the Building Authority, rest upon solid foundations and upon footings similar in every respect to the foundations of the walls against which such chimneys are built.

72. The back of every chimney-opening, from the hearth up to the height of four feet above the level of the fire-grate, shall be at least nine inches thick if in a party wall, or at least four and a half inches thick if not in a party wall.

Windows, Storeys and Rooms.

(2) Provided always that the provisions of this section shall not apply in any case in which the Crown lease has specially provided for the erection of buildings of a greater depth than thirty-five feet; and provided further that the Governor in Council may in any other case in his discretion grant exemption from or modification of the provisions of this section.
