RV parking rules in SeaTac

SeaTac RV parking at a glance

Street rules differ from city-lot limits

SMC 9.05.080 prohibits stopping on the traveled portion or impeding roadway travel, subject to specified transit and collection-vehicle exceptions. Posted street restrictions apply under 9.05.090. Section 9.05.116 separately sets a 24-hour default on city parking areas and city-owned or operated property when no time signs apply, absent lawful authority or permission. Do not read that as a universal street allowance or an airport parking rule.

Off-street storage and surfacing

SMC 15.455.450 specifies all-weather pavement such as concrete, asphalt or permeable pavement for off-street parking and vehicle-storage lots unless Public Works approves otherwise. The chapter’s application provisions, existing approvals and overlay requirements matter. Confirm the actual parcel, surface and use with the city; a compliant pad alone does not establish permission for RV storage or sleeping.

RV park storage is not an occupied RV site

Under 15.465.600, a manufactured-home park may provide resident RV storage without hookups, and no RV in that storage area may serve as living quarters. Approved occupied RV areas are a different route: designated sites, city-reviewed plans, permitted utility hookups, health/building standards, screening and a 180-day annual limit, with physical disconnection and at least 24 hours out of the park before reconnecting. Public camping is restricted under 8.25, whose enforcement text retains location and shelter-availability distinctions. Ask the city about any occupied public-site use instead of assuming a parking limit permits it.

Who to contact for your setup

Ask SeaTac 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 SeaTac parking checker to organize the starting conditions. The checker cannot approve a parcel, a variance or an unverified exception.
