Oregon Revised Statutes Counties and County Officers § 215.281

(1) Dairies and dairying are an important part of Oregon agriculture and make a significant contribution to the state and local economies;

(2) Dairies require continuous on-site labor to operate the dairy and to protect the significant investment in milking and waste disposal facilities, equipment and livestock necessary to operate a commercial dairy; and

(3) Dairies require more on-site housing than other types of farms because of the year-round labor-intensive nature of a dairy operation and justify different standards for the review of a primary or accessory dwelling customarily provided in conjunction with a commercial dairy farm under ORS 215.213 and 215.283.
