Oregon Revised Statutes Property Rights and Transactions § 90.538

(1) A landlord shall, upon written request by the tenant, make available for inspection by the tenant all utility billing records relating to a utility or service charge billed to the tenant during the preceding year. The landlord shall make the records available to the tenant during normal business hours at an on-site manager's office or at a location agreed to by the landlord and tenant. A tenant may not abuse the right to inspect utility or service charge records or use the right to harass the landlord.

(2) If a landlord fails to comply with a provision of ORS 90.531 to 90.539, the tenant may recover from the landlord an amount equal to one month's periodic rent or twice the amount wrongfully charged to the tenant, whichever is greater.
