515. Every person who carries out the demolition of an immovable or causes it to be carried out without a permit or in contravention of the conditions of the permit is liable to a fine of not less than $5 000 nor more than $25 000.
In addition, the by-law contemplated in article 496 may require that person to restore the immovable so demolished to its former condition. Where the offender fails to restore the immovable in accordance with the by-law, the council may cause the work to be carried out and recover the costs thereof from the offender, in which case article 510 applies, with the necessary modifications.
