Clackamas County Board scheduled to adopt rules allowing ADUs and RVs to be used as second dwellings in specific residential zones

Main Content

On May 8, the Clackamas County Board of Commissioners approved amending the county zoning code to provide access to more affordable housing in unincorporated residential areas of the county. The proposed amendments would allow property owners to do the following:

  • Build an accessory dwelling unit (ADU) on rural residential properties that are at least two acres, outside of an urban growth boundary (UGB) and outside of an urban reserve. 
  • Use a recreational vehicle (RV) as a second dwelling on certain residential properties if the site is either inside the Portland Metro UGB, or is both outside of a UGB and outside of an urban reserve.

The amended ordinance is expected to be adopted by the Board at its regular business meeting on Thursday, June 6, and go into effect later this summer.
