Received a 90-day notice of rent increases of 14.5%, is this legal?

Related: ORS 90.323; ORS 90.324

Oregon caps rent increases once per year, and the maximum percentage is recalculated annually (it was 14.5% in some past years and near 10% for 2025). A park cannot raise a household’s rent more than the current statutory cap or more than once a year.

It does not apply to apartment or other standard ORS 90.100–90.465 rentals. It is not legal advice. Talk with an attorney about your situation.
