This section says the rules apply to designing, building, installing, and moving factory-built buildings in the city, but only if they are sold to the first user. Manufactured homes that meet federal HUD standards are exempt, except for their foundations, stairs, additions, and accessory structures, which must follow the building and residential codes. All other building, housing, electrical, and plumbing codes still apply unless this article says otherwise.
