16. Site Formation.—The ground on which any new building is erected, and the ground immediately adjoining any such new building, shall be so formed and graded that no water can lodge thereon or under such building, or run under such building, and no person shall commence the erection of any building upon any site having matter thereon which in the opinion of the Inspector might prove deleterious to the health of the occupants of such building until such matter has been removed to the satisfaction of such Inspector.

17. Air-spaces.—No person shall erect a new dwellinghouse in the district unless he provides at the side or in the rear thereof an open space exclusively belonging to such house, and of an aggregate area of not less than six hundred square feet: Provided that such open space shall extend throughout the entire width, or in the alternative throughout the entire depth, of the site, and shall be free from any erection thereon above the level of the ground, and shall be so maintained while the site is occupied by the house: Provided also that the minimum distance across such open space from every part of any dwellinghouse, or from every part of any washhouse, shed, convenience, or other erection belonging thereto, shall be as follows:—

(b.) If the height exceeds fifteen feet, but does not exceed twenty-five feet: Twenty feet.

(c.) If the height exceeds twenty-five feet, but does not exceed thirty-five feet: Twenty-five feet.

(d.) If the height exceeds thirty-five feet: Thirty feet.

(e.) The provisions of this clause shall be deemed to be complied with if the open space at the rear and side of any dwellinghouse is equal to one and one-half the area that would be required to be left at the side or at the rear if the provisions of this clause were complied with, even though the various subsections hereof have not been strictly complied with: Provided that the minimum distance across the open space so provided shall be clear of all obstructions for not less than fifteen feet from every part of the dwellinghouse.

For the purpose of these by-laws, where the side boundaries of any site are not of the same length, the mean length of such side boundaries shall be taken as the depth of the site for the purpose of defining the distance across such open space, and the height of a dwellinghouse shall for the purposes of these by-laws be measured from the average level of the ground immediately adjoining the side or rear of such dwellinghouse, as the case may be, to the level of half the vertical height of the roof or to the top of the parapet, whichever is the higher.

18. Preventing Reduction of Space.—No person shall make any alteration or addition to any dwellinghouse (whether erected before the coming into operation of these by-laws or not) whereby the open space attached to such dwellinghouse shall be diminished by such alteration or addition so as to leave a less open space than is required by these by-laws to be provided.
