Is Your March Renewal Already on the Clock?
Count back 90 days from a March 1, 2027 lease renewal, and you land on December 1, 2026. That is the last day your tenant can receive a compliant rent increase notice, and it arrives faster than most Oregon owners expect.
On September 28, 2026, the Oregon Department of Administrative Services announced the maximum allowable rent increase for 2027: 10%, up from 9.5% in 2026. This guide explains how the number was set, which rentals it covers, the notice rules that still apply, and how Portland's relocation ordinance changes the math.
At Sleep Sound Property Management, our team has spent more than 17 years helping owners across the Portland metro and Vancouver, WA, navigate rent stabilization without leaving money on the table.
Key Takeaways
- The cap hit its ceiling: Oregon's 2027 maximum rent increase is 10%, the highest amount state law permits.
- Not every rental is covered: Units whose first certificate of occupancy was issued less than 15 years before the notice are exempt, and large manufactured home parks and marinas face a lower cap.
- Timing still rules: Oregon requires 90 days' written notice, allows one increase per 12 months, and bars increases during a tenancy's first year.
- Portland adds a twist: An increase of 10% or more inside city limits triggers mandatory relocation assistance.
- Strategy beats the maximum: Pricing renewals around market data and tenant retention usually protects more income than taking the full cap.
How Oregon Calculated the 2027 Rent Cap
The 10% figure comes from a fixed formula, not a fresh political decision each year.
Under ORS 90.324, the state must publish the maximum increase by September 30 each year. For most residential rentals, the cap equals 7% plus the annual change in the Consumer Price Index, with a hard ceiling of 10% added by Senate Bill 611 in 2023.
For 2027, seven percent plus inflation landed above that ceiling, so the cap defaulted to the 10% maximum. Owners who want to see the full calculation can review the methodology on the Oregon Office of Economic Analysis rent stabilization page.
The practical takeaway is that 10% is a limit, not a target. It sets the legal upper boundary, but it says nothing about what your local market will support or what your current tenant will accept.
Which Rentals Fall Under the 10% Cap
Before planning any increase, confirm which category your property belongs to.
Standard Residential Rentals
Most single-family homes, duplexes, condos, and apartments follow the 10% cap under ORS 90.323. This covers the bulk of the homes our team oversees through our Portland property management services.
Newer Construction
The cap does not apply when a unit's first certificate of occupancy was issued less than 15 years before the date of the rent increase notice. If you rely on this exemption, Oregon law requires your notice to state the facts that support it.
Manufactured Home Parks and Marinas
Facilities with more than 30 spaces are held to a flat 6% for 2027 under ORS 90.600. Facilities with 30 or fewer spaces follow the standard 10% limit.
If your portfolio mixes building types, our multifamily property management team can help you match each property to the right rule.
The Renewal Rules That Still Apply
The cap is only one piece of a compliant rent increase in Oregon.
90 Days' Written Notice
After the first year of a tenancy, landlords must give at least 90 days' written notice before an increase takes effect. Week-to-week tenancies require only seven days. The notice must state the amount of the increase, the new rent, and the effective date.
One Increase Every 12 Months
Rent can go up only once in any 12-month period, and not at all during the first year of a tenancy. That makes the timing of each increase just as important as the amount.
Plan Around Your Lease Calendar
Every increase you send sets your next opportunity to adjust rent a full year out. Our lease renewal process tracks those dates for each property so notices go out on time, and our Oregon landlord-tenant law resource covers the broader rules.
The cap tells you the most you can charge. Your vacancy costs tell you the most you should charge.
Why a Full 10% Increase Can Backfire in Portland
Inside Portland city limits, the maximum legal increase comes with a built-in cost.
Under Portland City Code 30.01.085, any rent increase of 10% or more within a rolling 12-month period triggers mandatory relocation assistance. If the tenant chooses to move out, the landlord owes a relocation payment, which starts at $2,900 for a studio under the city's administrative rules.
Increases of 5% or more also require a city-specific written notice that describes the tenant's rights. Landlords who miss these steps can be liable for up to three times the monthly rent, plus actual damages, relocation assistance, and attorney fees.
That is why many Portland owners stop just short of the 10% mark. A slightly smaller increase can still lift income while avoiding a relocation payment that could erase months of the gain.
What Vancouver, WA Owners Should Know
Rentals across the river follow a separate state law with its own rules.
Washington's House Bill 1217, passed in 2025, created a statewide rent cap under RCW 59.18.700. The Washington State Department of Commerce has also set the 2027 limit at 10%, but the exemptions and notice requirements differ from Oregon's.
For example, Washington exempts units whose first certificate of occupancy was issued within the past 12 years, and its law requires a specific notice format. Owners with properties in both states should never reuse an Oregon renewal template in Washington. Our Vancouver property management team and Washington landlord-tenant law guide can help you stay on track.
How to Build Your 2027 Renewal Plan
A clear process turns the new cap into a revenue decision instead of a compliance scramble.
Map Every Lease Date
List each lease expiration and last increase date for 2027. Then count back 90 days, plus a buffer for your delivery method, to set firm notice deadlines.
Price Against the Market, Not the Cap
Compare current rent to recent comparable listings before choosing a number. Our Portland rental market reports offer a helpful starting point for local trends.
Weigh the Real Cost of Turnover
A vacancy means lost rent, cleaning, repairs, and marketing time. Sleep Sound averages 30 days on market, yet even one empty month can outweigh the extra income from a larger increase. Our vacancy loss calculator helps you run the numbers.
Keep Strong Tenants in Place
For residents who pay on time and care for the home, a moderate increase often delivers a better long-term return than pushing to the limit.
Frequently Asked Questions
Here are answers to the questions owners ask most about the 2027 cap.
Can I raise rent during a tenant's first year?
No. For tenancies other than week-to-week, Oregon law bars rent increases during the first year. After that, you need 90 days' written notice and can raise rent only once in any 12-month period.
Does the 10% cap apply to my newer rental home?
Not if the first certificate of occupancy was issued less than 15 years before the date of your increase notice. You still need to give proper notice and state the basis for the exemption.
Do I have to raise rent by the full 10%?
No. The cap is a maximum, not a requirement. Many owners choose a smaller increase based on market rents, tenant quality, and turnover costs, especially in Portland, where 10% or more triggers relocation assistance.
