Oregon landlords have 31 days from the date you surrender possession of the rental unit to return your security deposit or deliver an itemized written accounting of every deduction.
Oregon gives your landlord exactly 31 days to return your deposit
Under ORS § 90.300, the timeline begins the day you deliver physical possession back to the landlord. Surrendering possession typically means vacating the home and returning all keys. If you surrender possession on June 1, the landlord must have your payment or statement delivered or postmarked by July 2.
The 31-day statutory cutoff is firm.
Oregon law does not allow a landlord to delay this process because of scheduling conflicts, vendor invoices, or ongoing repairs. If the landlord fails to place the refund or written accounting in the mail by the 31st day, the landlord has violated Oregon law.
Why missing an itemized list triggers ORS § 90.300 penalties
A landlord cannot keep any portion of your security deposit without providing an itemized written accounting. Under Oregon security deposit law, deductions are permitted only for specific lawful reasons, including unpaid rent or physical damage to the property caused by tenant negligence or abuse.
Deductions cannot be made for normal wear and tear. Everyday deterioration resulting from ordinary residential use is the landlord's operational expense.
The required itemized list must explicitly detail every deduction. Lump-sum entries such as "repairs: $500" or generic labels do not fulfill the statutory requirement for itemization. If a landlord withholds money without delivering an itemized statement detailing each dollar subtracted within 31 days, they lose the legal authority to keep those funds.
Calculating the 2x statutory penalty on wrongfully withheld funds
ORS § 90.300 establishes a penalty multiplier of up to two times the amount wrongfully withheld. This financial consequence prevents landlords from retaining tenant money without legal justification.
Consider how this calculation works in practice. Suppose your security deposit was $1,500. You surrender the keys on October 1. The 31-day statutory deadline expires on November 1. On November 20, the landlord sends you $500 and retains $1,000 without providing the required itemized list. Because the deadline lapsed and the landlord failed to supply an itemized accounting, the $1,000 withholding is wrongful under ORS § 90.300.
Under the statutory penalty formula, the court can penalize the landlord twice the amount wrongfully withheld. Twice $1,000 is $2,000 in statutory penalties. Adding the $1,000 wrongfully withheld deposit principal, the landlord faces a potential total recovery against them of $3,000.
If the landlord withholds the entire $1,500 deposit past the 31-day window without an itemized statement, the 2x penalty applies to the full sum. In that situation, twice the $1,500 deposit equals a $3,000 penalty, creating a total claim of $4,500.
Key handover date, deposit amount, and the day the 31-day window closed
A formal demand letter organizes the exact timeline, statutory rules, and monetary calculations so the landlord understands the exposure under ORS § 90.300. Writing down the facts methodically gives the recipient a clear basis to settle the matter before court intervention.
Your letter should include these specific items:
- The date you surrendered possession of the premises and handed over the keys.
- The full dollar amount of the security deposit paid at move-in.
- The date the 31-day window ended under ORS § 90.300.
- A direct notification that the landlord failed to provide the deposit or the mandatory itemized deduction list.
- A detailed calculation showing the deposit balance owed plus the 2x statutory penalty for wrongful withholding.
- A specific deadline for payment, typically 10 to 14 business days from receipt.
- The address where the landlord must mail the payment.
Send your letter using USPS Certified Mail. The USPS Certified Mail barcode and delivery confirmation provide formal verification that the landlord received the demand on a specific date, establishing an undeniable record of your dispute.
Taking a claim up to $10,000 to an Oregon small claims department
When a landlord ignores a demand letter, the next forum for resolution is the circuit court small claims department. Under ORS 46.405, Oregon small claims departments have jurisdiction over recovery actions where the amount in controversy does not exceed $10,000.
Most security deposit disputes fit within this $10,000 limit even after applying the 2x statutory penalty. For example, if a tenant disputes a withheld $3,000 deposit and claims the maximum 2x penalty of $6,000, the total claim is $9,000. That entire claim remains under the $10,000 statutory ceiling.
If your combined claim for the deposit and statutory damages exceeds $10,000, you must choose whether to file in the regular civil division of the circuit court or waive any recovery above $10,000 to stay in small claims.
In the small claims department, hearings are held without formal juries. Your demand letter, the postal delivery tracking record, your lease agreement, and photographs of the property condition form the documentary core of your presentation.
When a demand letter is the wrong tool for an Oregon tenancy dispute
A demand letter is tailored specifically for post-tenancy monetary claims where a landlord failed to meet statutory duties. Certain legal situations require a completely different approach.
If fewer than 31 days have passed since you surrendered the premises, a demand letter is premature. The landlord remains within the statutory period allowed by ORS § 90.300, and no legal violation has occurred yet.
If the landlord has filed a bankruptcy petition, sending a demand letter violates the federal automatic stay. In that situation, any attempt to collect the deposit must go through the federal bankruptcy court.
If you are in an ongoing tenancy dispute involving habitability, lockouts, or pending eviction proceedings, a deposit demand letter does not fit your legal posture. Security deposit claims under ORS § 90.300 only ripen after possession has terminated and the 31-day accounting clock expires.
