Where plans of a building are, in accordance with building byelaws, deposited with a local authority, and the plans show that it is proposed to construct a building of materials to which this section applies, or to place or assemble on the site a building constructed of such materials, the authority may, notwithstanding that the plans conform with the byelaws—
If a building in respect of which plans ought under the building byelaws to have been deposited, but have not been deposited, appears to the authority to be constructed of such materials as aforesaid, the authority, without prejudice to their right to take proceedings in respect of any contravention of the byelaws, may fix a period on the expiration of which the building must be removed and, if they think fit, impose such conditions with respect to the use of the building as might have been imposed under the last preceding subsection upon the passing of plans for the building and, where they fix such a period, shall forthwith give notice thereof, and of any conditions imposed, to the owner of the building.
Any person aggrieved by the action of a local authority under this section in rejecting plans, or in fixing or refusing to extend any period, or in imposing or refusing to vary any conditions, may appeal to a court of summary jurisdiction.
The owner of any building in respect of which a period has been fixed under this section shall, on the expiration of that period or, as the case may be, of that period as extended, remove the building, and, if he fails to do so, the local authority shall remove it and may recover from him the expenses reasonably incurred by them in so doing, and, without prejudice to the right of the authority to exercise that power, he shall be liable to a fine not exceeding ten pounds and to a further fine not exceeding five pounds for each day during which the building is allowed to remain after the conviction.
A person who uses a building in contravention of any condition imposed under this section, or who permits a building to be so used, shall be liable to a fine not exceeding ten pounds and to a further fine not exceeding five pounds for each day on which the offence continues after conviction therefor.
A local authority may by their building byelaws provide that the provisions of this section shall apply to any materials specified in the byelaws as being materials which are, in the absence of special care, liable to rapid deterioration, or are otherwise unsuitable for use in the construction of permanent buildings.
The provisions of this section shall apply in relation to any extension of an existing building as they apply in relation to a new building.
