Oregon Revised Statutes Revenue and Taxation § 307.621

(1) The city or county shall approve or deny an application filed under ORS 307.618 within 180 days after receipt of the application. An application not acted upon within 180 days shall be deemed approved.

(2) Final action upon an application by the city or county shall be in the form of an ordinance or resolution that shall contain the owner's name and address, a description of the subject multiple-unit housing, either the legal description of the property or the assessor's property account number, and the specific conditions upon which the approval of the application is based. On or before April 1 following approval, the city or county shall file with the county assessor and send to the owner at the last-known address of the owner a copy of the ordinance or resolution approving or disapproving the application. In addition, the city or county shall file with the county assessor on or before April 1 a document listing the same information otherwise required to be in an ordinance or resolution under this subsection, as to each application deemed approved under subsection (1) of this section.

(3) If the application is denied, the city or county shall state in writing the reasons for denial and send notice of denial to the applicant at the last-known address of the applicant within 10 days after the denial.

(4) The city or county, after consultation with the county assessor, shall establish an application fee in an amount sufficient to cover the cost to be incurred by the city or county and the assessor in administering ORS 307.600 to 307.637. The application fee shall be paid to the city or county at the time the application for exemption is filed. If the application is approved, the city or county shall pay the application fee to the county assessor for deposit in the county general fund, after first deducting that portion of the fee attributable to its own administrative costs in processing the application. If the application is denied, the city or county shall retain that portion of the application fee attributable to its own administrative costs and shall refund the balance to the applicant.
