(3) The department shall maintain publicly available information on its website about the maximum annual rent increase percentages for the previous calendar year and for the current calendar year and, on or after September 30th of each year, for the following calendar year.

ORS § 90.324 establishes the annual process by which Oregon's maximum allowable rent increase percentage is determined and disclosed. Each year by September 30th, the Oregon Department of Administrative Services calculates the cap—either a flat six percent for larger manufactured dwelling facilities, or the lesser of ten percent or seven percent plus the West Region CPI for smaller facilities and standard residential tenancies. The department is then required to publish that figure in a press release and keep current and prior-year figures accessible on its public website.

Under ORS § 90.324, property owners and managers should monitor the Oregon Department of Administrative Services' annual September 30th publication to confirm the maximum rent increase percentage applicable to their tenancy type before issuing any rent increase notice. Operators of manufactured dwelling facilities with more than 30 spaces work with a fixed six-percent ceiling, while those with 30 or fewer spaces—and landlords of standard residential tenancies under ORS 90.323—apply the lower of ten percent or seven percent plus the published CPI figure. Compliant operators typically verify the current year's published cap on the department's website and ensure any rent increase notice reflects a percentage at or below that threshold.

ORS § 90.324 gives tenants a publicly accessible benchmark to check whether a rent increase they receive falls within the legally permitted annual maximum. The Oregon Department of Administrative Services is required to publish the applicable cap each year by September 30th and to maintain that information on its website, making it straightforward to look up the limit for the current and prior calendar years. Tenants who believe a proposed increase exceeds the ceiling calculated under this section may consider raising that as a defense in any eviction or dispute proceeding, contacting a local tenant-rights organization, or reaching out to the Oregon Department of Administrative Services for clarification on the published figures.
