What is a CPI-linked rent increase in Pennsylvania?
A CPI-linked rent increase ties the annual rent adjustment to the federal Consumer Price Index. Pennsylvania statewide rent caps that include a CPI factor (such as California's AB 1482, which uses 5 percent plus regional CPI capped at 10 percent total) measure CPI for the relevant region in the 12 months preceding the increase. A landlord using CPI-linked rent in a non-rent-cap Pennsylvania jurisdiction can use any CPI measure (national, regional, or "all urban consumers" CPI-U), but the lease must specify which one and the calculation method. Tenants should verify the math: published CPI numbers are public on the Bureau of Labor Statistics website, and a 1 percent error in CPI calculation on a 1-year tenancy at $1,500 rent is $180 over-paid. 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.
