Washington Desertification of Manufactured and Mobile Homes is a process used to ensure that these homes meet the state’s safety and construction regulations. The Washington State Department of Labor & Industries (L&I) is responsible for the desertification of manufactured and mobile homes in the state. It is a mandatory process that must be completed prior to the sale, transfer, lease, or rental of any manufactured or mobile home in the state. Washington Desertification of Manufactured and Mobile Homes covers two categories: Desertification for Electrical Systems and Desertification for Structural Integrity. Desertification for Electrical Systems involves verifying that the electrical wiring and systems meet the National Electrical Code and other safety requirements. Desertification for Structural Integrity requires an inspection of the home’s structure to ensure that it meets all state requirements for construction and durability. Both processes must be completed in order for the home to be certified and allowed to be sold, transferred, leased, or rented in Washington.
