I live in Pennsylvania. We entered into a multi year lease two years ago. The original lease has a 'no pet' clause. Shortly before the start of our third year (this year) of the original lease, the landlord approved the addition of a pet with a pet addendum with the stipulation we paid an additional $1,000 'pet' security deposit. We had already paid a security deposit prior to moving in that was equal to one months rent. We were also required to pay both first and last months rent in advance. We are in the third year of a multi year lease and in the state of PA there are legal limits to security deposits designed to protect both tenant and landlord. In the second and subsequent years of a lease, the landlord cannot retain more than a single months worth of security deposit and this includes charging any additional deposits exceeding the statutory maximum. Both parties were unaware of this at the time the agreement was made for the pet addendum and additional deposit. We became aware of our legal rights and attempted to negotiate the deposit down rather than cite the law. The landlord allowed us to purchase and house our small animal prior to the deposit being paid while they drafted the addendum. We still have not paid deposit attempting to negotiate and now citing our legal rights regarding security deposits and landlord is threatening to evict if unpaid or we dont get rid of the pet now because original clause is no pet. Addendum was created without knowledge of security deposit laws and pet purchase approved prior to landlord receiving deposit (it took them 4 weeks to draft addendum). What are our legal options? On one hand they're violating our rights by requesting an additional deposit that now exceeds pa statutory second year maximum but are telling us the dog has to now go despite approval for it on a now illegal deposit addendum. Finally, the aninal is in process of being certified emotional support for my kid and this all seems to run afoul of Ada, fha, and security deposit law. Can they now force us to get rid of the dog or evict if we fail to pay now knowing our rights?
