Oregon Revised Statutes Public Health and Safety § 433.150

(1) Any city or municipality may establish a quarantine hospital within or without its own limits, but if within its own limits, consent of the municipality within which it is proposed to establish such hospital shall be first obtained. Such consent shall not be necessary if the hospital is more than 800 feet from any occupied house or public highway.

(2) When a great emergency exists the board of health may seize and occupy temporarily for such quarantine hospital any suitable vacant house or building within its jurisdiction and the board of health of any city or municipality having a quarantine hospital shall have control over the same. However, in case of use of such house or premises, due compensation shall be tendered for their use.
