Compare this market What changed Start a property worksheet

Does the operating permit transfer?: New application
Sections 6-151(a)(3) and 6-154(d) make registration nontransferable and treat a new owner of an existing STR as a new applicant under the rules then in effect. Apply within 30 days of purchase. The seller's registration does not reserve a capped non-owner-occupied slot for the buyer.
Can the land-use approval continue?: Verify the property approval
The operating-permit rule does not establish whether this parcel’s zoning approval, variance or older-use protection continues. Obtain the actual approval and its conditions.
Can this buyer obtain approval?: Mainland single-family homes and condos must be owner-occupied. The mainland non-owner-occupied cap changes from 400 to 1.5% of registered long-term rentals; Peaks Island has a separate framework.
License or registration: The city 2026 FAQ describes annual licensing and a December 31 renewal deadline.
Application availability: Annual cap and waitlist rules
Ask the city for the current published allocation. The FAQ says late renewals can enter the waitlist and describes a separate Peaks Island cap.
Timing to verify: Apply to register within 30 days of purchase or transfer of management or responsibility. Registration is incomplete until the city accepts the required information and fees.
Changes and uncertainty: New tenant-occupied STRs are not allowed beginning in 2026. Do not use Portland, Oregon rules or an older fixed 400-unit cap for this city.
