Oregon has one of the most structured and detailed late fee systems in the nation under ORS 90.260. Governed by the Oregon Revised Statutes, late fees are tightly regulated, with a mandatory grace period, multiple capped calculation methods, and specific billing requirements.

Late Fees Must Be in Writing and Timely Billed

Under ORS 90.260(1), a landlord cannot charge a late fee unless:

1. The specific terms (type, amount, and due dates) are clearly stated in the written rental agreement.
2. The late charge is imposed or billed no later than 30 days after the date the rent was due.

If the lease is silent on late fees or if the landlord fails to bill the fee within the 30-day window, no fee can be legally charged.

Mandatory 4-Day Grace Period

Under ORS 90.260(1)(a), a late charge cannot be imposed until rent is not received by the fourth day of the weekly or monthly rental period. This means a landlord cannot assess a late fee until the 5th day. The 4-day period is a statutory minimum; landlords may choose to provide a longer grace period in the lease.

Structured Late Fee Options

Oregon law (ORS 90.260(2)) provides three permitted late fee structures. A landlord must choose one:

A critical limitation for both daily and periodic fees is that they cannot carry over or continue to accumulate into subsequent months; they are capped by the duration of the specific rental period in which the rent was late.

Changing Late Fee Terms

In periodic tenancies (such as month-to-month leases), a landlord may change the type or amount of the late charge by providing at least 30 days' written notice to the tenant under ORS 90.260(3).

Non-Payment of Late Fees ≠ Eviction for Non-Payment

A critical distinction in Oregon: non-payment of a late charge alone is NOT grounds for terminating a tenancy for non-payment of rent.

Under ORS 90.260(6):

• If a tenant pays rent but refuses to pay the late fee, the landlord cannot issue a non-payment eviction notice (ORS 90.394).
• A landlord may include the late charge on a non-payment notice (ORS 90.394) only if the notice clarifies that the tenant may cure the notice by paying only the delinquent rent.
• Unpaid late charges are grounds for termination for cause under ORS 90.392 (with a 30-day notice and 14-day cure period).

Prohibition on Deducting Late Fees from Future Rent

Under ORS 90.260(4), a landlord is prohibited from deducting a previously imposed late charge from a current or subsequent rent payment to make that payment delinquent for the purpose of imposing new late charges or terminating the tenancy for non-payment. This prevents landlords from artificially creating a "non-payment" situation.

Best Practices for Oregon Landlords

1. Choose One Clear Late Fee Method: Pick the flat fee or the 5%-per-5-day method and spell it out precisely in your lease.
2. Bill Promptly: Ensure all late fees are billed within 30 days of the rent due date to remain enforceable.
3. Respect the Rental Period Cap: Stop the accumulation of daily or periodic fees at the end of the rental period in which they were incurred.
4. Notice for Changes: Always provide 30 days' written notice before adjusting late fee structures in month-to-month agreements.
5. Correct Notice Language: If including late fees on a non-payment notice, explicitly state that the tenant only needs to pay the rent to avoid eviction.
