ADUs and RVs as options for secondary dwellings
Second dwelling options: Accessory Dwelling Units (ADUs) in rural residential areas and Recreational Vehicles (RVs) in rural and urban residential areas
To help support access to more affordable housing in unincorporated Clackamas County, on August 1, 2024, the Board of County Commissioners adopted an ordinance approving amendments to the county’s Zoning & Development Ordinance (ZDO) that allow:
- An accessory dwelling unit (ADU) on certain rural residential properties, and
- Using a recreational vehicle (RV) as a second dwelling on certain urban and rural residential properties.
The ordinance became effective September 3, 2024.
Rural Accessory Dwelling Units (ADUs)
An accessory dwelling unit is a second (usually smaller) dwelling unit located on the same lot as a detached single-family home or manufactured home. It may be attached or detached from the single-family home or manufactured home.
Historically, state law has not allowed ADUs in rural areas. State legislation in 2021 and 2023 changed these rules, however, and now can now allow ADUs in rural residential areas, provided the site is outside of an urban reserve. The specific requirements rural ADUs must meet are as described in the following documents.
Requirements for RVs
A recreational vehicle is a vehicle licensed by the state that:
- Is designed for human occupancy
- Is designed to be used temporarily for recreational, seasonal, or emergency purposes, and
- Has a gross floor area not exceeding 400 square feet when set up.
RVs include park trailers, travel trailers, pick up campers, motor homes, fifth-wheel trailers, and camping and tent trailers.
Historically, siting an RV as a residence on private property was prohibited in Clackamas County, except in limited circumstances, such as temporary dwellings for care or while building a permanent dwelling. But because of recent state law changes, the county may now allow certain property owners to place one RV on their property for use as a second dwelling. RVs may be permitted as second dwellings on land zoned for single-family residential use that is within the unincorporated areas of Clackamas County (outside cities) and:
- Inside the Portland Metro urban growth boundary (UGB), or
- Both outside of an urban growth boundary (UGB) and outside of an urban reserve.
Specific requirements that must be met in order to site an RV as a second dwelling are described in the following document.
