Oregon Rent Control Laws (2026) | The Complete Guide

Typically, Oregon rent control laws are governed primarily by statewide legislation that sets limits on how much landlords can raise rent and how often increases can occur. These laws apply to most residential rental properties and are designed to balance tenant protection with landlord flexibility.

Under Oregon rent control laws, landlords can generally increase rent only once every 12 months for a given tenant. Any increase must also stay within a legally defined annual cap and must be communicated with proper written notice. This prevents sudden or excessive rent hikes and gives tenants time to adjust or make informed decisions.

The law also works alongside broader tenant protection rules, including notice requirements and restrictions on certain types of evictions. Together, these measures create a structured system where rent increases are predictable, regulated, and subject to clear legal standards.

One of the most important aspects of Oregon rent control laws for both landlords and tenants to understand is the annual rent increase cap, and what rules govern how and when a landlord can apply it.

The Oregon Department of Administrative Services has published the Consumer Price Index (CPI) for 2025, calculated at 2.5%. Pursuant to Oregon law, which sets the rent control limit at the lesser of 7% plus CPI or 10%, the rent increase limit for 2026 is 9.5%, unless an exemption applies. This means that for most residential rental properties in Oregon, landlords cannot raise rent by more than 9.5% in 2026.

This structure ensures that Oregon rent control laws remain flexible enough to reflect economic changes while still protecting tenants from steep or unpredictable rent increases.

While Oregon rent control laws cover many residential properties, several categories are exempt from the rent increase cap. These exemptions are designed to encourage new development and accommodate certain housing types.

Oregon's rent control cap generally does not apply to:

Rental units where the certificate of occupancy was issued less than 15 years ago

Properties that have undergone major renovations in the last 15 years

Government-subsidized or federally certified affordable housing

Landlords who own two or fewer single-family homes or condos

Week-to-week tenancies

The first tenancy in a unit following a vacancy

Oregon rent control laws set clear rules that landlords must follow when increasing rent, managing tenancies, and enforcing lease terms. These laws, primarily found in Oregon Revised Statutes Chapter 90, are designed to balance profitability for landlords with stability and protection for tenants and they include:

#1. Annual Rent Increase Limits

Oregon sets a firm ceiling on how much landlords can raise rent each year. Each year, the Oregon Department of Administrative Services calculates the maximum rent increase permitted under the state's rent stabilization law, ORS 90.323 and ORS 90.324, with the 2026 official maximum set at 9.5% for most residential rental units 15 years and older.

#2. Frequency of Rent Increases

Hitting the percentage cap is not the only rule, frequency matters too. As Oregon Business confirms, Senate Bill 608 limits landlords to one rate increase per 12 months and protects tenants who have lived in a unit for a year from no-cause evictions.

#3. Notice Requirements for Rent Increases

Landlords must provide written notice before increasing rent. For most tenancies, this means giving at least 90 days’ notice, clearly stating the new rent amount, the percentage increase, and when it takes effect.

#4. Just-Cause Eviction Rules

After the first year of tenancy, landlords must provide a legally valid reason to terminate a lease. This “just-cause” requirement is a core part of Oregon rent control laws and prevents arbitrary evictions. Hence, acceptable reasons include:

Nonpayment of rent

Lease violations

Owner move-in or major renovations

#5. Relocation Assistance Obligations

Landlords who terminate tenancies for qualifying reasons carry a financial obligation too. According to Oregon laws, landlords who have an ownership interest in five or more dwelling units must pay a relocation fee of one month's rent along with the termination notice. Additional local rules (e.g., in Portland) may impose higher payments or broader requirements.

#6. Property Exemptions

Not all properties are subject to rent control. Common exemptions include:

Newer buildings (generally less than 15 years old)

Certain owner-occupied properties

Some subsidized housing

Landlords must confirm whether their property qualifies for exemption before applying or disregarding rent caps.

#7. Record-Keeping and Compliance Requirements

Landlords are expected to maintain accurate records of:

Lease agreements

Rent payments

Notices and communications

Proper documentation helps demonstrate compliance with Oregon rent control laws and protects against disputes or legal challenges.

Staying compliant with Oregon rent control laws requires attention to detail, proper documentation, and consistent adherence to legal procedures. Whether you're a landlord or property manager, here's how you can stay compliant with the laws:

#1. Follow Rent Increase Rules Strictly

Landlords must:

Stay within the annual rent cap (7% + CPI)

Increase rent no more than once every 12 months

Provide proper written notice before increases

Failure to comply can lead to legal disputes or penalties.

#2. Understand Property Exemptions

Not all properties are subject to rent control. Hence, landlords should confirm whether their property qualifies for exemptions (e.g., newer buildings or owner-occupied units) before applying or ignoring rent caps.

#3. Maintain Clear Documentation

Accurate records are essential. This includes lease agreements, rent payment history, notices of rent increases, and communication with tenants. Proper documentation protects landlords in case of disputes.

#4. Comply with Just-Cause Eviction Rules

Landlords must ensure that any eviction complies with Oregon’s legal requirements, especially after the first year of tenancy. Acting outside these rules can invalidate the eviction.

#5. Use Organized Systems for Property Management

Managing compliance manually can lead to errors. Tools like Platuni can help landlords and property managers track rent increases, store documents, and maintain clear communication records. This reduces mistakes and ensures alignment with Oregon rent control laws.

#6. Stay Updated on Legal Changes

Rent control laws can change based on legislative updates or inflation adjustments. Therefore, staying informed ensures ongoing compliance and helps landlords adapt quickly.
