Rent increase limits generally apply per space regardless of who lives there, but many members report large resets when a home resells — this is a frequent source of confusion and worth a dedicated FAQ.
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.
Withholding rent is only legally protected in narrow habitability situations, requires written notice first, and is risky without legal help — OSTA consistently advises members not to do this without an attorney.
Mandatory mediation covers habitability, safety, and conduct disputes, but by law excludes rent amount, rent increases, and nonpayment-of-rent terminations — those can still be discussed outside formal mediation.
