Rent Control: Beaverton vs Tualatin

Who enforces rent control rules in Washington County?

Washington County's code enforcement division is responsible for rental property ordinances. You can report violations or request information through the Washington County government website or by calling the main municipal line.

What are typical penalties for violating rent control rules?

Most Washington County rental property violations start with a written warning followed by escalating civil fines for repeat offenses. Specific dollar amounts and any criminal-misdemeanor exposure depend on the section of code; consult Washington County's municipal code or staff for the current penalty schedule.

Does Tualatin have its own rent-control ordinance?

No. The City of Tualatin has not adopted a city-level rent-control ordinance. Rent regulation inside Tualatin city limits is governed entirely by the statewide rent cap under ORS 90.323 (and ORS 90.600 for manufactured-home facilities), enacted by Senate Bill 608 in 2019. The cap limits annual rent increases on covered residential units to 7% plus the September West Region CPI, with a hard ceiling of 10%; the maximum for calendar year 2026 is 9.5%, as published by the Oregon Office of Economic Analysis.

How much can a Tualatin landlord raise my rent in 2026?

For a covered unit (one whose first certificate of occupancy was issued at least 15 years before the date of the rent-increase notice and which is not otherwise exempt under ORS 90.323(7)), the maximum increase in calendar year 2026 is 9.5%, published by the Oregon Office of Economic Analysis. The landlord must give at least 90 days' written notice that identifies the percentage increase, the new rent amount, and the effective date. An increase above 9.5% on a covered unit is unenforceable and exposes the landlord to three months' rent plus actual damages under ORS 90.323(5).

Which Tualatin rentals are exempt from the rent cap?

Three primary categories are exempt under ORS 90.323(7): (1) any dwelling in a building for which the first certificate of occupancy was issued less than 15 years before the date of the rent-increase notice (the new-construction exemption); (2) subsidized housing units where the rent is set by a federal, state, or local program; and (3) certain narrowly defined other categories. The exemption is determined unit-by-unit and may change as buildings age past the 15-year threshold; an exemption claim that turns out to be wrong exposes the landlord to the ORS 90.323(5) liability for three months' rent plus actual damages.
