Oregon's maximum rent increase for 2027
Oregon publishes next year's allowable rent increase by September 30. Here is what is already settled for 2027, what is still to come, and the date the notice has to be in a resident's hands for a January 1 increase.
| Your park | 2026 | 2027 |
|---|---|---|
| More than 30 spaces | 6% | 6% — fixed in statute, not recalculated |
| 30 spaces or fewer | 9.5% | Publishes by September 30, 2026 |
The 6% park cap is not waiting on anything
This is the part most owners get wrong, and it is new. House Bill 3054, effective September 1, 2025, wrote a flat 6% into ORS 90.324(1)(a) for manufactured-dwelling and marina facilities with more than 30 spaces. That number is a literal figure in the statute, not a formula — it is not tied to CPI, and the Department of Administrative Services does not recalculate it each September the way it does the general one. Unless the legislature amends the statute again, a park with more than 30 spaces should expect 6% in 2027, and can draft the notice in early September without waiting for anything.
If your facility has 30 spaces or fewer, you are on the general formula below, and you do have to wait.
The general formula, and who publishes it
ORS 90.324 sets the general maximum annual rent increase as the lesser of:
- 10%, or
- 7% plus the September annual 12-month average change in the Consumer Price Index for All Urban Consumers, West Region (All Items), as most recently published by the U.S. Bureau of Labor Statistics.
The Oregon Department of Administrative Services, Office of Economic Analysis calculates it and must publish it by September 30 each year, for the following calendar year. One practical warning from last cycle: DAS posted a correction to the 2026 figures the day after the original September 30 release. Give the number a day to settle before you print 60 notices.
The recent numbers
| Calendar year | 30 spaces or fewer / general tenancies | More than 30 spaces |
|---|---|---|
| 2024 | 10.0% | Same — the split did not exist yet |
| 2025 | 10.0% | Same — the split did not exist yet |
| 2026 | 9.5% | 6% (first year of the split) |
| 2027 | Publishes by September 30, 2026 | 6% expected — fixed by statute |
The 90-day notice timeline for a January 1, 2027 increase
Oregon requires at least 90 days' written notice before the effective date of a space-rent increase under ORS 90.600, and no more than one increase in any 12-month period. Counting back from January 1, 2027:
| Date | What has to happen |
|---|---|
| September 30, 2026 | Mail-only notices should be dated by here — practitioners add three days for mail service. Also the DAS publication deadline for the 2027 general figure. |
| October 3, 2026 | The 90-day deadline. The notice has to be delivered on or before this date for a January 1, 2027 effective date. |
| January 1, 2027 | The new rent takes effect. |
Notice the squeeze. For a park of 30 spaces or fewer, the 2027 figure is not required to publish until September 30, 2026 — and a mailed notice for January 1 should already be going out that same week. If you are near the line, decide in advance whether you will hand-deliver (which buys you until October 3, 2026) or push the effective date to February 1 and take the extra month.
Run your own number
Other Oregon rules worth knowing
- Once per 12 months. One increase per tenancy per 12-month period, whatever the percentage.
- Manufactured park spaces run under their own chapter. ORS 90.505–90.850 govern park tenancies; the general ORS 90.323 rules do not apply to them. The 90-day notice period is the same either way, but the statute you cite in a notice should be the right one.
- New construction. The percentage cap does not apply to a unit whose first certificate of occupancy was issued less than 15 years before the notice date.
- Subsidized housing. Certified affordable housing is exempt where the increase does not raise the tenant's own share, or is required for program eligibility.
- The HB 3054 infrastructure exception. The bill added a one-time increase for major infrastructure or capital repairs, subject to an affirmative vote of tenants representing a majority of the facility's spaces, and it limits the increase a park can impose on the purchaser of an existing home in the park. We have not been able to confirm every threshold against the primary bill text, so read HB 3054 itself before relying on either one.
Common questions
When does Oregon publish the 2027 maximum rent increase?
By September 30, 2026. ORS 90.324 requires the Department of Administrative Services to calculate the figure and publish it by September 30 each year for the following calendar year, and to keep the numbers on the Office of Economic Analysis website. In the 2025 cycle DAS posted a correction to the figures the day after the original release, so it is worth waiting a day and re-reading the final post before you commit a number to a notice.
What is the maximum rent increase for a mobile home park in Oregon?
It depends on the size of the park, and this changed for 2026. A manufactured-dwelling park or marina with more than 30 spaces is capped at a flat 6% under House Bill 3054, which wrote that number directly into ORS 90.324(1)(a) — it is not CPI-adjusted, so it does not move each September the way the general figure does. A facility with 30 or fewer spaces uses the general formula instead, which was 9.5% for 2026.
How is Oregon's general rent cap calculated?
ORS 90.324 sets it as the lesser of 10%, or 7% plus the September annual 12-month average change in the Consumer Price Index for All Urban Consumers, West Region (All Items), as most recently published by the U.S. Bureau of Labor Statistics. Because 7% plus CPI has run above 10% in recent years, the figure has been at or near the 10% ceiling: 10.0% for 2024, 10.0% for 2025, and 9.5% for 2026.
How much notice do I have to give for an Oregon lot rent increase?
At least 90 days' written notice before the effective date, under ORS 90.600, and no more than one increase in any 12-month period. Manufactured dwelling park space tenancies run under ORS 90.505–90.850, not the general ORS 90.323 rules, but the headline notice period is the same 90 days. Practitioners commonly add three days when a notice goes out by mail only.
When do I have to send the notice for a January 1, 2027 increase?
On or before October 3, 2026 for a January 1, 2027 effective date, or September 30, 2026 if you are relying on mail alone. That is the squeeze: for a park of 30 or fewer spaces, the 2027 figure is not required to publish until September 30, 2026 — the same week the notice has to go out. A park with more than 30 spaces already knows its number is 6% and can prepare the notice in early September.
Does the cap apply if I just bought the park, or just did a big capital repair?
The cap applies to the tenancy, not to your ownership, so buying the park does not reset it. HB 3054 did add a one-time exception for major infrastructure and capital repairs, subject to an affirmative vote of tenants representing a majority of the spaces in the facility, and it also limits what a park can charge a purchaser of an existing home in the park. The thresholds are specific and we have not been able to confirm every one of them against the primary bill text, so read HB 3054 itself — linked in the sources below — before you rely on either.
