Some municipalities simply don’t allow THOWs to be used for full-time living within their jurisdictions. While cities like Seattle, Tacoma, Bellevue, Everett and many others in King, Snohomish, Pierce, Skagit and Island Counties DO allow additional, or secondary, living spaces on residential properties, they require the structures to meet the International Residential Code (IRC). Our DADUs are built to current IRC standards and leave our factory with the building inspection (again by Labor & Industries) already completed and ready for placement on location. Our THOW models meet rigorous safety and build standards. They leave our facility with the Washington State Department of Labor & Industry’s RV insignia, a certification that is recognized in all 50 states. Check your jurisdiction’s eligibility below.
