Why an association in Portland should read this

Because the fines land on owners inside associations, and because an association's own enforcement sits on top of the city's rather than replacing it.

An owner operating an unpermitted accessory short-term rental in a Portland condominium can simultaneously face a four- or five-figure city fine, an association fine under ORS 94.630 or the condominium equivalent, and a covenant-enforcement action. The city does not consult the association, and the association has no ability to mitigate the city penalty.

The practical consequence for a board is that an owner who gets caught may be facing a financial shock large enough to affect assessment payment. A $27,513 fine against an owner in a building with a $400 monthly assessment is a delinquency risk the board will feel.

The other Portland rule

Portland adopted Title 24.31, Short-Term Rental Requirements, following a council hearing on December 4, 2024, with rules effective January 1, 2025. It applies exclusively to short-term rentals in the strict sense — commercial-zone, no resident on site — and not to accessory short-term rentals.²

The trigger was an October 2024 State Building Codes Division directive requiring such regulation to be formalised as a local ordinance or licensing requirement. Contemplated requirements include NFPA 13D residential sprinklers, additional fire-rated exterior wall materials, emergency egress windows, and egress width, ceiling, landing and door-lock standards.

The background is a jurisdictional carve-out worth knowing. The 2023 Oregon Residential Specialty Code at R101.2.3.1 excludes “post-occupancy lease or rental arrangements, short-term rentals, vacation rentals, and similar uses” from that code's authority, while affirming that municipalities may regulate locally. Oregon has, by design, left short-term rental safety standards to cities.

For an association, the sprinkler and egress items are the ones that reach common elements. Retrofitting NFPA 13D sprinklers into a unit in an attached building is not a unit-only project.

A small piece of relief in state law

House Bill 3505, chapter 83, Oregon Laws 2025, effective January 1, 2026, bars local system development charges for installing or upsizing an NFPA 13D residential fire sprinkler system. That removes one cost layer from exactly the kind of retrofit Portland's rules contemplate, though it does nothing about the installation itself.

A board's options

Know which regime a member is in. Accessory short-term rental — owner or long-term resident on site — is the Type A and Type B permit world with the fine schedule above. A commercial-zone short-term rental with no resident is Title 24.31 and the building-safety requirements. The two have different rules, different costs and different enforcement.

Then decide what the association's own position is, in writing, before an owner asks. Our Oregon short-term rentals page covers what a declaration can and cannot restrict, and our Oregon fining authority page covers what an Oregon association must do before it fines anyone — written notice, an opportunity to be heard, and a delivered fine schedule under ORS 94.630.

That last point is worth dwelling on. Portland's ombudsman criticised the city for fining without warning. An Oregon association has no such option: the statute requires notice and an opportunity to be heard before a fine, and the fine must rest on a schedule the owner has been given.

What to watch next

Whether the city adopts the ombudsman's recommendations, particularly the retroactive reduction to $7,255 and the 95-day hard cap. A 95-day annual limit would be a meaningful constraint on the economics of accessory short-term rentals in Portland, and it would change what an owner in an association can realistically do with a unit.
