Navigating nonpayment of rent is one of the most challenging situations a housing provider in Portland, Oregon can face. Oregon’s Residential Landlord and Tenant Act (ORS Chapter 90), combined with City of Portland local ordinances and Multnomah County court procedures, imposes strict legal requirements on landlords. A single procedural oversight—such as miscalculating a notice period by one day or making an arithmetic error on a written demand—can cause a dismissed eviction case and court-ordered payment of tenant legal fees.
When rent goes unpaid, following a structured, compliant process protects your financial investment while upholding legal obligations.

Step 1: Check the Date and Review Your Lease Agreement
Before taking formal action, verify the timeline outlined in both your lease agreement and state law.
- Grace Period Rules: In Oregon, rent is legally late on the second day of the rental period. However, ORS 90.260 mandates that landlords cannot charge late fees until rent remains unpaid through the end of the fourth day of the rental period (meaning late fees may only be assessed starting on the fifth day).
- Late Fee Caps: Late fees must be clearly stated in the written rental agreement and cannot exceed statutory limits (a reasonable flat fee, a daily fee capped at 6% of the flat fee, or a 5% monthly fee).
Step 2: Initiate Direct Communication
In many cases, nonpayment stems from a temporary financial disruption, a banking glitch, or a personal crisis. Reaching out early via phone, email, or your online portal can resolve the issue without formal legal proceedings.
- Inquire Promptly: Contact the tenant on the fifth day of the month to ask about the status of the payment.
- Inform About Rental Assistance: Provide information about local emergency rental assistance resources in Multnomah County. Oregon law requires specific disclosures regarding rental assistance resources alongside nonpayment notices.
- Document Everything: Maintain a written record of all calls, text messages, emails, and portal notes detailing your interactions.

Step 3: Serve the Required Notice to Pay or Quit
If communication fails and rent remains unpaid, you must serve a formal written notice terminating the tenancy for nonpayment under ORS 90.394. Under Oregon law, you have two primary options for month-to-month or fixed-term tenancies:
10-Day Notice to Pay or Quit
- Earliest Service Date: Can be served no sooner than the 8th day of the rental period (including the 1st day rent was due).
- Cure Period: Gives the tenant 10 full days from the date of service to pay the outstanding balance in full or vacate.
13-Day Notice to Pay or Quit
- Earliest Service Date: Can be served no sooner than the 5th day of the rental period.
- Cure Period: Gives the tenant 13 full days from the date of service to pay the balance or vacate.
Essential Notice Content Requirements
To be legally enforceable in Portland, your notice must explicitly state:
- The exact amount of unpaid rent required to cure the nonpayment (do not include late fees, utility balances, or damages in this cure total).
- The specific date and time by which the payment must be received to stop termination.
- Designated location and acceptable methods for making payment during the notice period.
- Statutory legal disclosures regarding rental assistance and legal aid resources, including required Multnomah County attachments.

Step 4: Ensure Legal Delivery under ORS 90.155
Proper service is critical. Delivering a notice improperly renders it legally invalid, requiring you to restart the entire notice window. Acceptable delivery methods include:
- Personal Delivery: Handing the written notice directly to the tenant.
- First-Class Mail: Mailing the notice via standard first-class mail. Crucial Rule: When serving by mail, ORS 90.155(2) requires adding 3 additional calendar days to the required notice period.
- Attachment and Mail (“Nail and Mail”): Attaching the notice securely to the main entrance of the dwelling unit and sending a copy via first-class mail on the same day. This method is only permitted if your written lease agreement specifically authorizes “attachment and mail” service for both landlord and tenant.
Step 5: Handle the Cure Period Properly
During the notice period, the tenant holds the right to cure the default by paying the full unpaid rent listed on the notice.
- If the Tenant Pays in Full: The tenancy continues normally. You cannot refuse full payment made within the cure deadline.
- Partial Payments: Be extremely cautious with partial payments. Accepting a partial rent payment after serving a notice can waive your right to proceed with termination unless you execute a written partial payment agreement specifying conditions and deadlines under ORS 90.417/90.412.

Step 6: File a Forcible Entry and Detainer (FED) Action
If the cure deadline passes without full payment or move-out, you cannot change locks or remove belongings yourself. Self-help evictions are illegal in Oregon and expose landlords to heavy statutory damages.
- File the Complaint: File a Forcible Entry and Detainer (FED) action in Multnomah County Circuit Court.
- Serve the Summons: A court summons and complaint must be served on the tenant by a civil process server or county sheriff.
- First Appearance Hearing: Both parties attend a preliminary court date. If the tenant fails to appear, a default judgment is granted. If the tenant contests the filing, the case may proceed to mediation or a full trial.
- Writ of Execution: If granted possession by the judge, the court issues a Notice of Restitution giving the tenant a short window to vacate. If they remain, only the Multnomah County Sheriff can physically execute a Writ of Execution to return possession to you.
Critical Pitfalls to Avoid
- Incorrect Math: Overstating rent owed invalidates the notice under Oregon court precedent (Hickey v. Scott).
- Including Non-Rent Charges: Lumping late fees or utilities into the required “cure amount” on a nonpayment notice renders the notice defective.
- Retaliation: Raising rent, cutting services, or serving nonpayment notices in response to a tenant exercising legal rights is unlawful.
By adhering strictly to ORS Chapter 90 and local Multnomah County court procedures, you ensure your rights as a landlord remain protected while managing nonpayment professionally and lawfully. Consulting a licensed Oregon landlord-tenant attorney is always recommended for complex disputes.
