Pennsylvania state law does not specify how much notice landlords or tenants must provide to end a month-to-month rental agreement, but 30 days is typical. Your rental agreement should provide this information. Landlords may not terminate a tenancy for a discriminatory or retaliatory reason, and different rules apply if you have not paid rent or violated other terms of your rental agreement, or if you have signed a fixed-term lease.
