OAR 350-082-0550: Consolidation of Lots

(1) A unit of land shall be consolidated with adjacent units of land in the same ownership if: (a) In Oregon, the subdivision within which the unit of land is located is undeveloped pursuant to ORS Chapter 92; or (b) In Washington, if the unit of land is smaller than the current minimum parcel size and is located within a final plat that is older than five years from the date of filing. (2) No portion of a consolidated subdivision or plat shall be considered a separate parcel solely because an existing parcel overlays, and possibly fragments, that consolidated subdivision or plat. (3) Section (1) shall not be applied to consolidate two or more units of land where each unit of land is developed with a dwelling that qualifies as an existing use. One or more undeveloped units of land shall be consolidated with one or more developed units of land. (4) To carry out 350-082-0550, counties shall develop their own procedures for consolidating units of land, including amending plats, vacating plats, replatting, or other similar action.
