A Landlord cannot collect damages from you for lost rents during a period that the Landlord is likewise collecting rent from another Tenant (or double recovering). In any breach situation, Landlords are entitled to recover lost rents for the period of time for which the premises is otherwise unrented (plus any reduced rents which are received in mitigation of the damages). However Landlords have a duty to mitigate their damages.
With that being said, and with the caveat of not reading your Lease, there is a strong possibility that the "Inadequate Notice Fee" is characterized in your Lease as liquidated damages. Liquidated damages are a set sum which a party to a contract agrees to pay if he/she breaks some promise and which, having been arrived at by a good faith effort to estimate the actual damages that will probably ensue from breach, is recoverable as agreed-upon damages if breach occurs. In other words, rather than waiting for a breach to figure out what the actual damages are, the parties agree ahead of time to set a flat amount of damages. A liquidated damages clause is assumed to be valid unless the challenging party proves its application amounts to an unenforceable penalty, meaning that the liquidated damages are disproportionate to the actual damages sustained by the injured party.
