How much notice must be given

How much notice must be given in pa for a rent increase

If you have a written lease the landlord cannot increase the rent before the end of the lease unless the lease says they can.

If you don't have a written lease the landlord must give you one rental period of notice. That means if you have a month-to-month lease the landlord must give you one month of notice. If you have a week-to-week lease the landlord must give you one week of notice.

There is no limitation on the amount of the rent increase.
