Based on your post I’m assuming that you are implying that the “roommate” is the acting landlord due to her name being on the deed? If that is true, then yes, you should have several ways to get out of your lease based on any of the following:
Breach of Quiet Enjoyment
Breach of Unauthorized Pet
Breach due to unsafe or illegal activity
Violation of Implied Agreement
Normally, if a roommate violates the agreement it would not allow for the other roommate to claim a breach of contract, since the contract is with the renter and landlord and not with the roommate. Your daughter should be able to get out of the lease IF she is acting as more than just a lousy roommate.
