Is a lease valid if the apartment was not ready on the date of the move in date of the lease?

Possession on the date contracted, CAN BE grounds to terminate, depending on the circumstances. However, since you are in the apartment now, your options are likely limited to damages you can show for the 2 day delay. You'd wnat to send a demand letter documenting your damages to the LL before trying to file in small claims.

I am an attorney in SF it is grounds for eviction here. You should consult with your local Reading PA attorney for a free consultation. Breach of contract is a just reason for termination. But if you already moved in then the rent should be rebated. Instead of paying full rent deduct those 2-3 days from the total rent due. It looks like PA have three reasons for eviction: nonpayment of rent, breach of lease contact and end of the lease term (example month to month, lease ends at end of the month).
