All previously occupied mobile homes, manufactured homes, designated manufactured homes, or modular homes shall be inspected by the Washington State Department of Labor and Industries and brought up to the most recent HUD specifications before being granted an occupancy permit. Prior to occupancy, even those having a HUD certificate must first be approved by the city building inspector to determine whether through misuse, neglect, alterations, or accident the mobile home, manufactured home, designated manufactured home, or modular home has fallen below safety and livability standards of the Uniform Building Code. All new mobile homes, manufactured homes, designated manufactured homes, or modular homes must meet HUD and Uniform Building Code requirements. All fees must be paid.
