0ECDVJ Vehicles parked on unapproved surfaces BLDG Immediate Investigation Requested: Unpermitted Commercial Staging Yard & Graffiti at Address: 21131 31st Ave S, SeaTac, WA 98198 Violation Details: I am submitting critical new evidence regarding the illegal commercial staging yard operation at this residential property. The scope of the violations has escalated drastically into active commercial exploitation and criminal property damage: Illegal Commercial Shuttle/Transit Depot: Attached photos catch the operators in the act of loading groups of customers carrying rolling luggage into the commercial passenger vans. They are actively running a high-turnover charter, shuttle, or transit dispatch depot directly out of a residential zone without a business license. Severe Heavy-Duty Truck Violations: The operators have now parked massive, Class 6 medium-duty commercial box trucks directly on the unpaved dirt yard. These large logistics vehicles heavily exceed 19,500+ lbs GVWR. This is nearly double SeaTac’s strict 10,000 lbs residential zoning weight limit, creating a severe neighborhood nuisance and risking damage to residential terrain.Public Roadway Defacement (Graffiti): The operators have spray-painted massive text ("DO NOT... THIS IS OUR YARD EXIT") directly across the public asphalt road and shoulder right-of-way. This constitutes explicit public property defacement and illegal obstruction/claiming of a public street. They have also spray-painted neighboring personal vehicles.This property is operating as an open, unpermi 08/11/2026
