Oregon Revised Statutes Public Health and Safety § 456.290

(2) An affordable housing covenant is valid and enforceable even if the covenant violates the rule against perpetuities set forth in ORS 105.950 to 105.975.

(3) If a court denies equitable enforcement of an affordable housing covenant because of a change of circumstances that renders the covenant not in the public interest, the court may award damages as the only remedy in an action to enforce the affordable housing covenant.

(4) The court may not use a comparative economic test as a basis for a determination that an affordable housing covenant is not in the public interest.
