What Are Oregon Landlord-Tenant Laws I Need to Know?
Oregon is widely recognized as one of the most tenant-protective states in the country. The Oregon Residential Landlord and Tenant Act (ORLTA), codified in Oregon Revised Statutes Chapter 90, establishes a comprehensive legal framework governing nearly every aspect of the rental relationship - and Portland layers additional protections on top through its own city code.
For landlords, understanding these laws isn't optional. Violations can result in financial penalties, loss of rent, and civil liability. The good news is that the rules are well-documented and, once understood, straightforward to follow with consistent practices.
At Uptown Properties, staying current on Oregon landlord-tenant law is a core part of what we do for our clients every day. Here's a practical overview of the provisions that matter most.
The Foundation: Oregon's Residential Landlord and Tenant Act (ORS Chapter 90)
The ORLTA applies to virtually all residential rental agreements in Oregon, with limited exceptions for certain institutional housing and transient lodging. It establishes baseline rights and obligations for both parties and cannot be waived by lease agreement - meaning you cannot write a lease that strips tenants of their statutory rights, even if a tenant signs it.
Rent Increases: The Rules Are Strict
Oregon made national history in 2019 when it became the first state to enact statewide rent control legislation. Here's how it works in 2026:
Rent stabilization cap: For buildings with certificates of occupancy issued more than 15 years ago, annual rent increases are capped under ORS 90.323 and 90.324. The Oregon Office of Administrative Services sets the maximum allowable increase each year by September 30th for the following year. For 2026, that cap is 9.5%. Landlords who violate this cap are liable for three months' rent plus actual damages.
Notice requirements: Landlords must provide at least 90 days' written notice before any rent increase takes effect for month-to-month tenancies (ORS 90.323). No rent increase is permitted within the first year of a tenancy.
New construction exemption: Properties with a certificate of occupancy issued within the last 15 years are exempt from the rent stabilization cap. If your property is newer construction, standard notice requirements still apply, but there is no percentage cap on increases.
Security Deposits: What's Allowed and Required
Oregon law (ORS 90.300) does not set a maximum cap on security deposit amounts, but deposits must be disclosed in the written lease agreement and a receipt must be provided to the tenant at the time of payment.
Security deposits cannot be increased during the first year of a tenancy. When the tenancy ends, the landlord must return the deposit - along with an itemized statement of any deductions - within 31 days of the tenancy's termination. Deductions are only permissible for unpaid rent, damage beyond normal wear and tear, and other costs specifically authorized by the lease.
Failure to return the deposit within 31 days can expose the landlord to a penalty equal to twice the amount wrongfully withheld, plus the tenant's attorney fees. This deadline is strictly enforced.
Property Entry: 24 Hours Notice Is Required
Under ORS 90.322, landlords must provide tenants with at least 24 hours' written notice before entering a rental unit. The notice must state the date, time, and reason for entry. This applies to repairs, inspections, showings to prospective tenants or buyers, and all other non-emergency access.
The 24-hour requirement is waived only in genuine emergencies - fire, flooding, or situations where immediate entry is necessary to prevent serious harm. Self-help entry without notice, or using entry as a form of pressure on a tenant, is unlawful and can expose landlords to significant liability.
Habitability: Your Ongoing Obligation
ORS 90.320 requires landlords to maintain rental units in a habitable condition at all times. This is not a one-time obligation at move-in - it's a continuing duty throughout the tenancy. A habitable unit under Oregon law must have:
- Effective weatherproofing and weather protection on the roof and exterior walls
- Plumbing facilities in good working order
- Adequate hot and cold water supply
- Functioning heating facilities
- Electrical lighting with wiring in safe condition
- Buildings and grounds free from debris, pests, and unsanitary conditions
- Working smoke alarms and fire safety measures
When a tenant notifies a landlord of a habitability issue, Oregon law generally requires a response within a reasonable time - and as few as 7 days for urgent health and safety issues. Failure to maintain habitability can give tenants grounds to terminate the lease, withhold rent into escrow, or pursue damages.
Eviction: A Legal Process With Specific Requirements
Oregon law requires landlords to follow a specific legal process to remove a tenant. Self-help evictions - changing locks, removing belongings, or cutting off utilities to force a tenant out - are illegal and can result in substantial damages against the landlord.
Portland's just-cause eviction requirements apply to most rental housing in the city. Landlords must have a legally recognized reason to terminate a tenancy, including:
- Non-payment of rent (with proper notice)
- Repeated material lease violations after written warning
- Causing significant damage to the property
- The landlord or an immediate family member intending to occupy the unit as a primary residence
- The landlord intending to demolish or substantially remodel the unit
The required notice periods vary by cause. Non-payment of rent requires a 10-day notice to pay or vacate. Material lease violations typically require 30 days. For no-fault terminations (such as owner move-in), 90 days notice is generally required, and relocation assistance may apply.
Oregon SB 586 (enacted 2025 session) made further refinements to termination notice requirements for fixed-term tenancies. If your property is in Portland, reviewing current Portland city code alongside ORS Chapter 90 is essential before issuing any termination notice.
Late Fees and Other Charges
Oregon law (ORS 90.260 and 90.302) governs what fees landlords may charge. Late fees must be disclosed in the lease agreement and can only be charged when rent is at least four days overdue. The maximum late fee is the greater of $50 or 5% of the monthly rent. Landlords may not charge fees not authorized by statute or the written lease.
Anti-Retaliation Protections
ORS 90.385 prohibits landlords from retaliating against tenants who exercise their legal rights - including requesting repairs, contacting code enforcement, or joining a tenant organization. Retaliation includes raising rent, reducing services, or initiating eviction proceedings within a short period after a tenant takes a protected action. Courts presume retaliation if adverse action is taken within 90 days of protected tenant activity, and the burden shifts to the landlord to demonstrate a legitimate reason.
