A grantor may deduct from a security deposit paid under an occupancy agreement—
(a) the reasonable cost of repairs to, or the restoration of, the premises or any facilities, furniture or goods provided with the premises as a result of damage (other than fair wear and tear) caused by the occupant; and
(b) the reasonable cost of securing the premises if the occupant fails to return the keys for the premises to the grantor at the end of the agreement; and
(c) any occupancy fee or other amount owing and payable under the occupancy agreement at the time the agreement ends.
