Raising space rent in Oregon: the 2026 caps, exemptions, and penalties

Oregon rewrote the park rent-increase rules in 2025 (House Bill 3054, effective September 1, 2025), and 2026 is the first full year under them. The cap now depends on your park's size, the notice rules are strict, and the penalty for exceeding the cap is written into the statute. Here's the 2026 playbook.

The rules in ORS 90.600

For a month-to-month space tenancy you may not raise rent without 90 days' written notice before the effective date, more than once in any 12-month period, or by more than the capped percentage. The notice itself must state the dollar amount of the increase, the new rent, the effective date — and, if you're relying on an exemption to exceed the cap, the facts supporting it. Mail it early: served-by-mail notices need extra days in transit to still give a full 90.

Exemptions worth knowing

• New construction: a dwelling whose first certificate of occupancy is less than 15 years old is exempt from the cap.
• The new infrastructure increase (HB 3054): a park with more than 30 spaces can take a one-time increase of up to 12% — in lieu of, not on top of, that year's regular increase — to fund a significant infrastructure project. The conditions are real: at most once every five years, a written cost estimate and timeline to tenants, a tenant meeting, then approval by 51% of occupied spaces in a signed written vote — and if the project isn't substantially complete within a year of its estimated date, the increase must be refunded. It's a financing tool, not a loophole.

The penalty is specific

Exceed the cap and ORS 90.600 makes you liable to the tenant for three months' rent plus the tenant's actual damages. On a $600 lot that's $1,800+ per affected tenant — for a mistake a calculator prevents. (Run yours through the free lot rent increase calculator; it applies the 2026 park-size rule and rounds down.)

Also new under HB 3054

Two changes beyond rent worth flagging for park owners: tenants may now elect a facility-wide committee you're required to meet with on request (up to twice a year), and on home resales you may no longer require an interior inspection of the home — or condition sale approval on aesthetic or cosmetic upgrades (repairs and maintenance are still fair game).

Common Oregon mistakes

• Applying 9.5% to a 35-space park — over 30 spaces, the 2026 cap is 6%
• Memorizing this year's percentages: they reset every January
• A second increase inside 12 months, even a small one
• Claiming an exemption without stating the supporting facts in the notice
• Treating the 12% infrastructure increase as automatic — it needs the vote

The full two-state picture (Washington's flat 5% included) is in Oregon and Washington rent caps for 2026, and the notice generator drafts the 90-day letter once you have your number.
