Can PM Company legally charge tenant monthly administrative Fees

[Stan Mend]

I have a general question about Management Agreement :-

Can Property Management Company legally charge tenant MONTHLY administrative Fees for Pets.   There is a one-time non refundable deposit (administrative fee) per pet that goes to the Property Management company and then a MONTHLY administrative fee charged per pet for a MAX OF 3 PETS.   This ADMINISTRATIVE FEE goes directly to the Property Managers.  Owner/landlord doesn't get a distribution, but a clause in the management agreement states "Broker provides a $750 Pet Damage Guarantee to Owner and collects Pet Administrative Fees from tenants in order to cover the cost of this guarantee." with a condition that Owner should use PM's contractor for rent ready repairs. 

Is this valid/legal given that landlord is ultimately responsible for all repairs/fixes to the property.  Please let me know your thoughts on this.
