Oregon’s maximum allowable rent increase for 2027 is 10 percent, up from 9.5 percent in 2026. The state Department of Administrative Services, which calculates the figure each year, published the new number on September 28, 2026.
It is a ceiling, not an automatic raise. A landlord may increase rent by up to 10 percent in 2027 for covered tenancies, and many will choose a smaller amount or none. On a $1,500 monthly rent, the highest permitted increase is $150 a month, compared with $142.50 under this year’s 9.5 percent limit.
Whether a particular renter is covered comes down to the type of tenancy. The department’s release says the 10 percent figure applies to tenancies subject to ORS 90.324(b), the state rent stabilization law, and it points to ORS 90.323 for the tenancy types covered. Questions about how the increase is administered, and other landlord-tenant issues, go to Oregon Housing and Community Services.

How does Oregon set the 2027 cap?
The formula is written into state law. For most covered tenancies, the cap is the lesser of 10 percent or seven percent plus the Consumer Price Index, known as CPI, the government’s measure of how fast consumer prices are rising. The 2027 figure landed at the 10 percent ceiling.
The release does not state the CPI value used. It refers readers to a spreadsheet titled Maximum Annual Rent Increase 2027, which holds the methodology, the calculation and the CPI data. State law requires the department to calculate the figure no later than September 30 of each year.
What changed from 2026?
The allowable increase for calendar year 2026 was 9.5 percent, the department says, and the release links to a correction notice for the 2026 figures. The step up to 10 percent is half a percentage point.
That half point adds about $7.50 a month to the ceiling on a $1,500 rent, or $90 over a year. For a renter on a fixed income, the more important number is the total, since a 10 percent increase on a $1,200 rent is $120 a month, or $1,440 over a year, and a 9.5 percent increase on the same rent is $114 a month.
What is the limit for manufactured home parks and marinas?
A separate rule applies to some facilities, which the release defines as manufactured dwellings and marinas. At facilities with more than 30 spaces, covered tenancies under ORS 90.600(1) are capped at a flat six percent, not 10 percent. Because the six percent figure is flat, it does not move with CPI the way the 10 percent ceiling can from year to year, and the release says it applies to manufactured dwellings and marinas with more than 30 spaces. At facilities with 30 or fewer spaces, the lesser of 10 percent or seven percent plus CPI applies.
The difference matters in dollars. On an $800 monthly space rent at a facility with more than 30 spaces, a six percent increase is at most $48 a month. A 10 percent increase on the same rent would be $80, which is why the number of spaces at a park or marina is worth knowing before an increase notice arrives.
The release lists no exemptions and does not say when the 2027 figure takes effect, other than that it applies to calendar year 2027.
What should a renter find out before January?
The open question is whether a given home is covered. The department’s release names the tenancy types and the formulas, but it does not decide any individual case. A renter who gets an increase notice can compare the percentage with the 10 percent ceiling, or the 6 percent figure at a large park, and take questions about coverage to Oregon Housing and Community Services. The department’s media relations office, at [email protected], handles questions about the calculation itself.
Planning for a 2027 rent increase of up to 10%?
A rent increase of up to 10 percent lands on top of heating bills and repairs, and a household on a fixed income can lose track of which relief programs it applied for and when each renews. A missed renewal is an easy detail to lose in a year when rent is already rising.
The Senior Property Tax & Home-Cost Relief Kit does not cap rent. It covers the costs around the rent, with heating, cooling and home-repair help, an application log and renewal calendar, and the circuit-breaker credit that includes renters.
