About this page

Oregon rent late fee law

Oregon, ORS 90.260: a late charge needs a written rental agreement that states it, and it is allowed only when a monthly or weekly rental period reaches its fifth day without the rent having been received. The lease picks one limit: a reasonable flat amount once per period; a reasonable per-day amount starting on day five, no more than 6% of that flat amount per day; or 5% of the periodic rent per five-day period starting on day five, all within that rental period.

(1) A landlord may impose a late charge or fee, however designated, only if: (a) The rent payment is not received by the fourth day of the weekly or monthly rental period for which rent is payable; and (b) There exists a written rental agreement that specifies: (A) The tenant’s obligation to pay a late charge on delinquent rent payments; (B) The type and amount of the late charge, as described in subsection (2) of this section; and (C) The date on which rent payments are due and the date or day on which late charges become due. (2) The amount of any late charge may not exceed: (a) A reasonable flat amount, charged once per rental period. “Reasonable amount” means the customary amount charged by landlords for that rental market; (b) A reasonable amount, charged on a per-day basis, beginning on the fifth day of the rental period for which rent is delinquent. This daily charge may accrue every day thereafter until the rent, not including any late charge, is paid in full, through that rental period only. The per-day charge may not exceed six percent of the amount described in paragraph (a) of this subsection; or (c) Five percent of the periodic rent payment amount, charged once for each succeeding five-day period, or portion thereof, for which the rent payment is delinquent, beginning on the fifth day of that rental period and continuing and accumulating until that rent payment, not including any late charge, is paid in full, through that rental period only.

Before you send the late rent notice: it is a reminder letter about overdue rent and a late charge, not an eviction notice. A notice to pay rent or quit is a separate document, and Oregon has its own rules for it. Nothing on this page is legal advice.

What Oregon law says about invoice interest

[...] is nine percent per annum and is payable on: (a) All moneys after they become due; but open accounts bear interest from the date of the last item thereof. [...] no person shall: (a) Make a business or agricultural loan of $50,000 or less at an annual rate of interest exceeding the greater of 12 percent [...]

The usury cap reaches only money LOANS of $50,000 or less. Ordinary trade credit / unpaid invoices aren't loans, so they're uncapped; larger loans are uncapped too.
