2026 limit
9.5%
The most a rent can rise. This is a legal cap on how much rent can go up. The figure shown is the one set for that year. Exemptions, where the law has them, are listed below.
- Written notice of a rent increase
- 90 days before the new rent starts
- How often
- Once every 12 months
- First increase
- 12 months after the tenancy starts
- To raise rent by more than the cap
- No above-cap application exists; only units under 15 years old or regulated affordable housing are outside the cap
Worked example: a $1,500 apartment, new rent starting in 2027
| Rent today | $1,500.00 a month |
| Oregon's 2027 cap | 10.0% |
| Largest increase allowed | $150.00 a month |
The tenant must get written notice of 90 days before the new rent starts, and the last increase must be at least 12 months old.
What to watch for in Oregon
- ORS 90.323: no increase "during the first year after the tenancy begins", "written notice at least 90 days prior to the effective date", and not "more than once in any 12-month period". A landlord who breaks these rules owes three months' rent plus damages.
- Exempt from the cap: units whose first certificate of occupancy "was issued less than 15 years from the date of the notice of the rent increase", and regulated affordable housing. Cities and counties may not control rents (ORS 91.225).
