Oregon Late Fee Laws: Caps, Grace Period, and Pyramiding

Oregon late fee laws, set out in ORS 90.260, let a landlord charge for late rent only when a written lease authorizes the fee, the rent is at least four days overdue, and the amount fits one of three structures the statute allows.¹ A landlord who ignores any of those conditions cannot enforce the charge, and a tenant who was made to pay it can recover damages.

The Fee Must Be in a Written Lease

No written lease, no late fee. The rental agreement has to say three things: that the tenant owes a late charge on overdue rent, the type and amount of that charge, and the dates when rent is due and when the late charge begins.¹ A verbal understanding does not count. If none of that is in writing, the tenant owes only the rent itself, however late it arrives.

A landlord who wants to change the type or amount of the late charge during an ongoing tenancy must give at least 30 days’ written notice before the new terms take effect.¹ Announcing a higher fee and collecting it the next month is not allowed.

The Four-Day Grace Period

A landlord cannot impose a late charge unless rent has not been received by the fourth day of the rental period.¹ If rent is due on the first, the earliest a fee can hit is the fifth. The same rule applies to weekly rentals.

A lease provision that tries to shorten or eliminate this grace period is unenforceable. Oregon law prohibits rental agreements that waive tenant rights under the landlord-tenant statutes.² A fee charged on the second or third day of the rental period violates state law, and the tenant can dispute it.

How Much a Landlord Can Charge

Oregon allows a landlord to pick one of three fee structures, and the lease must specify which one applies. Mixing them within the same rental period is not permitted.¹

A reasonable flat fee, charged once per rental period. The statute does not set a dollar cap but defines “reasonable” as the amount customarily charged by landlords in that rental market. A flat fee well above local practice can be challenged.
A daily fee that begins on the fifth day and accrues each day rent remains unpaid through that rental period. The daily rate cannot exceed 6 percent of the reasonable flat fee for the market. If the reasonable flat fee is $50, the daily charge tops out at $3.
A recurring charge equal to 5 percent of the monthly rent, imposed once for each five-day period, or portion of one, that rent stays unpaid. It also begins on the fifth day. On a $1,500 rent, that is $75 for each five-day window of delinquency.

Both the daily and the percentage options stop accruing at the end of the rental period for which rent is overdue. Late fees do not roll forward and keep stacking into the next month. And under any structure, the fee attaches only to unpaid rent, never to previously unpaid late charges.¹

No Pyramiding of Late Fees

A landlord cannot deduct an unpaid late fee from a current rent payment and then treat the rent as short, triggering a fresh late fee on top of the old one.¹ That maneuver would let fees compound indefinitely, and the statute forbids it. When a tenant pays rent in full while still owing a prior late charge, the payment goes to rent first.

A landlord may charge simple interest on the unpaid late fee at the judgment rate under ORS 82.010, running from the date the fee was imposed.¹ The debt grows, but it grows as interest, not as new late fees.

What Happens If You Don’t Pay the Late Fee

An unpaid late charge does not expose you to the fast-track nonpayment-of-rent eviction. The 10-day or 13-day notice process under ORS 90.394 is reserved for actual unpaid rent, not for unpaid late fees.¹

What a landlord can do is pursue a for-cause termination under ORS 90.392. Oregon classifies nonpayment of a late charge as a material violation of the rental agreement. The landlord must serve a 30-day written notice describing the violation and giving the tenant at least 14 days to cure it by paying the outstanding fee. Pay within that window and the tenancy continues; miss it and the landlord can move forward with termination.³

Week-to-week tenants face a tighter clock. For a for-cause notice over unpaid late fees, the notice period drops to seven days and the cure period to four days.³ So an unpaid late fee will not produce a surprise eviction, but ignoring one is not safe either. If you believe the fee is unlawful, dispute it rather than letting it sit.

Deductions From the Security Deposit

When the tenancy ends, a landlord can claim from the deposit the amount reasonably necessary to cover the tenant’s defaults, including unpaid rent. Validly imposed late charges fall within that category as defaults under the rental agreement.⁴

The landlord must deliver a written accounting of each deduction within 31 days after the tenant turns over possession, and that accounting must explain the basis for each item. A vague entry like “fees owed” will not do. Miss the deadline or skip the written accounting, and the tenant can challenge the deduction in court.⁴

What You Can Do About an Unlawful Late Fee

Any lease clause that waives tenant rights or demands a prohibited payment is unenforceable. If a landlord deliberately writes a prohibited provision into the lease and tries to enforce it, the tenant can recover actual damages plus an amount up to three months’ rent.²

If a fee was assessed before the grace period ended, exceeded the statutory cap, or was never authorized in a written lease, you can refuse to pay and dispute it. If the landlord already took it from your deposit, you can sue to recover it, often in small claims court. Keep your lease, rent receipts, and any written communication about late charges.

Pushing back is protected. A landlord cannot retaliate for a tenant asserting rights under state or federal law, and that includes challenging a late fee. Retaliation covers raising rent, cutting services, threatening eviction, or filing an eviction action. A tenant who proves retaliation can recover up to two months’ rent or twice the actual damages, whichever is greater, and has a complete defense to a retaliatory eviction.⁵

When a Collection Agency Gets Involved

Direct collection by the landlord is governed by state law. The moment the debt moves to a third-party collection agency or an attorney acting for the landlord, the federal Fair Debt Collection Practices Act applies. The collector must send a written validation notice within five days of first contact, identify the amount owed and the original creditor, and tell you about the 30-day right to dispute the debt. Calls are limited to 8 a.m. through 9 p.m. local time, and the collector has to go through your lawyer if you ask. If you believe the underlying late fee was unlawful, dispute the debt in writing within that 30-day window.

Federally subsidized tenancies, such as Section 8, may be governed by program rules that differ from or add to Oregon’s late fee statute, and disputes there sometimes go through an administrative hearing rather than state court. Check your program-specific lease addendum for anything that overrides the state rules above.
