Legal Question in Landlord & Tenant Law in Pennsylvania

Re: Security Deposit

Not really statutorily illegal; i.e., the landlord-tenant act is silent on the issue. In reality, you should look at the language of your lease - it will tell you if it is permisible or not. The landlord may be able to sue you to recover the rent or if security deposit is applied to rent may be able to sue you for damage to the property that the security deposit would otherwise pay for. In general it is not a good idea to use it as your last months rent, but not illegal.
