Jurisdiction and research scope
Unincorporated Thurston County, Washington only. Incorporated cities and towns, tribal lands and separately administered public lands require their own governing rules. The applicable zoning code varies in rural areas and the Olympia, Lacey and Tumwater urban growth areas. Current-linked County affidavit updated September 24, 2021, and current CPED code-compliance guidance read November 6, 2026. The affidavit expressly spans four county zoning codes; ordinary storage and guest stays depend on the applicable code.

Thurston County RV parking at a glance
| Location or use | What to check |
|---|---|
| Driveway / yard | Residence construction must be on the RV parcel or an adjacent same-owner parcel. Confirm parcel setbacks, access, critical areas and any shoreline or floodplain restrictions. |
| Street / loading | The private-property rule does not authorize parking or camping on a public road. No independent extended loading exception is established by these sources. |
| Sleeping / utilities | Temporary construction-related occupancy under an accepted affidavit; stop within 30 days of final residence occupancy approval. Environmental Health must accept wastewater disposal before occupancy; other service permits remain applicable. |
Use the correct county zoning code
The county affidavit says its four zoning codes generally restrict extended RV occupancy unless the location is approved. Rural Title 20 rules should not be applied automatically to the Olympia, Lacey or Tumwater urban growth areas. Confirm both unincorporated status and the governing zoning code before relying on a storage or occupancy allowance.
An active residence project is required
The construction route requires an issued residential building permit, kept active with a good-faith effort toward completion. The residence must be on the RV parcel or an adjacent parcel under the same ownership. Temporary occupancy must cease within 30 days after the residence receives final occupancy approval. A future plan to build is not enough.
Wastewater approval before moving in
Environmental Health must accept the wastewater arrangement before temporary occupancy begins. Supply the required disposal explanation and keep the RV outside critical areas and their buffers. The owner signs the affidavit for the building-permit file. Failure to comply may result in immediate removal. This is not an independent street-parking, storage or permanent-residence approval.
Who to contact for your setup
Ask Thurston 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 Thurston County parking checker to organize the starting conditions. The checker cannot approve a parcel, a variance or an unverified exception.
