Can a Pennsylvania landlord raise rent at any time?
No. A Pennsylvania landlord cannot raise rent during a fixed-term lease (unless the lease itself provides for it). On a month-to-month tenancy or after a fixed term expires, the landlord may raise rent with the required advance written notice. Pennsylvania uses 68 P.S. 250.501 tenure-based notice: 15 days for tenancies under 1 year, 30 days for 1 year or more. No state rent cap. Rent changes on month-to-month tenancies follow the same notice ladder. Any increase served without the correct notice period, or that exceeds the applicable cap, is void.

This is an informational answer based on 68 P.S. 250.501 (Pennsylvania Landlord and Tenant Act 1951) as of early 2026. It is not legal advice. Housing law changes year to year and local ordinances (especially in rent-controlled or rent-stabilized cities) can override or add to state law. For contested cases, consult a Pennsylvania-licensed attorney.
