What Oregon law says about late fees
Oregon caps residential late fees at 5% of the monthly rent. On a $1,000-a-month rental, the most a landlord may charge for one late payment is $50.
The cap is a ceiling, not a default: your lease must still state the fee, and you may charge less than the maximum. Charging more than the cap risks the excess being declared unenforceable — and in a dispute or an eviction case, an unlawful fee can undermine your whole position.
The exact Oregon rule: Four-day grace. The statute allows one of three structures: (a) a reasonable customary flat fee; (b) a reasonable daily fee from day five, each day capped at 6% of the flat fee; or (c) 5% of the periodic rent for every succeeding five-day delinquency period. There is no single universal percentage maximum.
The Oregon grace period
Oregon gives tenants a 4-day grace period: rent is not legally “late” — and no late fee may be charged — until 4 days after the due date. If the tenant pays within that window, the calculator above correctly shows no fee.
Charging late fees in Oregon: putting it into practice
Three habits keep Oregon late fees defensible. First, put the exact fee in the lease before it is ever needed — you cannot invent a charge after the rent is already late. Second, apply it consistently and keep records: when rent was due, when it arrived, and what was charged. Third, remember that cities and counties can add their own rules on top of state law, so confirm local ordinances before relying on the statewide rule alone.

Frequently asked questions
What is the maximum late fee a Oregon landlord can charge?
The legal maximum is 5% of monthly rent. Your lease must still state the fee, and charging more than the cap risks the excess being unenforceable. The exact rule: Four-day grace. The statute allows one of three structures: (a) a reasonable customary flat fee; (b) a reasonable daily fee from day five, each day capped at 6% of the flat fee; or (c) 5% of the periodic rent for every succeeding five-day delinquency period. There is no single universal percentage maximum.
Is there a grace period for late rent in Oregon?
Yes — 4 days. No late fee may be charged until 4 days after the due date, and rent paid within that window is not legally late.
What if my lease charges more than the Oregon cap?
The excess may be unenforceable. The calculator above automatically reduces the allowable fee to the legal maximum of 5% of monthly rent — update the lease clause to match the cap rather than charging the higher figure.
Can I charge a late fee every day the rent is late in Oregon?
Generally, treat the late fee as a single charge per late payment rather than a daily penalty. A few states build per-day amounts into their caps (for example, Connecticut’s $5-per-day structure within its $50/5% ceiling, and Iowa’s tiered per-day limits) — follow the exact rule cited above and whatever your lease says, and never stack fees to punish.
