Legal Question in Landlord & Tenant Law in Pennsylvania

I guess you didn't keep a copy for yourself? The lease may have referenced it which would indicate that it was incorporated into the lease and made a part of it. If it doesn't and you can't produce one it will be up to a DJ to figure it out. Not having one would not work to your advantage if the Landlord claims you destroyed things that were destroyed when you moved in. They would then not give you back your deposit and you would not be able to prove those conditions existed when you moved in. Best of luck....
