Jurisdiction and research scope
Unincorporated Washington County, Oregon only, not Beaverton, Hillsboro, Tigard, Forest Grove, Sherwood or another incorporated city. This is not Washington state. Current county Development Review/Current Planning FAQs, undated, read November 6, 2026. The FAQs give vehicle-count and living-use guidance, not all parcel setbacks or a complete temporary-use code.

Washington County RV parking at a glance
| Location or use | What to check |
|---|---|
| Driveway / yard | One RV and one trailer per tax lot within overall vehicle counts; placement conditions need confirmation. Tax-lot counts do not waive setbacks, surface, screening or district requirements. |
| Street / loading | Private-tax-lot storage guidance does not decide public-street parking. No separate RV loading exception is established by the cited FAQs. |
| Sleeping / utilities | Ordinary RV living prohibited; approved health-hardship exception outside UGB. Temporary visitor use needs a specific answer. Storage counts do not authorize utilities or residential use. |
Count the entire tax lot
The county FAQ allows one RV and one trailer per tax lot. These are included in, rather than added to, the overall limit of four operable vehicles and one inoperable vehicle per tax lot. Ask Planning to classify a towable RV and confirm the actual tax lot before applying the count.
Living is a separate question
The county says living in an RV is prohibited except for a specifically approved health-hardship permit outside the urban growth boundary. The application requires physician documentation. A medical need or ownership of the land is not itself an issued approval.
Placement and limited guidance
The two FAQs do not establish every driveway surface, setback, screening or temporary guest-use condition. Street parking is also a separate issue. Confirm the parcel district, intended duration and service connections with Current Planning before storing or occupying an RV. Nearby city rules do not automatically apply in the unincorporated county.
Who to contact for your setup
Ask Washington County Planning or Code Enforcement to confirm jurisdiction, the actual parcel or road, vehicle classification, position, duration and intended use. Obtain the required road, building, electrical, plumbing or wastewater approvals before relying on a parking exception. Easements, HOA rules and leases remain separate. Start with the official rule or permit guidance.
Use the Washington County parking checker to organize the starting conditions. The checker cannot approve a parcel, a variance or an unverified exception.
