Under ORS 90.323 and 90.600, an Oregon landlord cannot raise rent during the first year of a tenancy, must give at least 90 days' written notice for any later increase, and may not raise rent more than once in any 12-month period. A statewide annual cap under ORS 90.324 limits the increase amount.
ORS 90.323 bars a landlord from increasing rent 'during the first year after the tenancy begins' and, after the first year, only 'without giving the tenant written notice at least 90 days prior to the effective date of the rent increase.' Increases are limited to 'once in any 12-month period.' The amount is capped statewide under ORS 90.324(1) at 'the lesser of: (a) Ten percent; or (b) Seven percent plus the September annual 12-month average change in the Consumer Price Index for All Urban Consumers, West Region.' Exceptions exist for units less than 15 years old and certain regulated affordable housing. ORS 90.600 sets parallel rules for manufactured-dwelling and floating-home facilities.
A landlord who raises rent above the ORS 90.324 cap is liable to the tenant for an amount equal to three months' rent plus actual damages. A notice that fails to meet the 90-day or once-per-year rules is invalid and the increase is unenforceable.
