(a) Providing instructions to purchaser or lessee.

(1) For each manufactured home sold or leased to a purchaser or lessee, the retailer must provide the purchaser or lessee with a copy of the manufacturer's DAPIA-approved installation instructions for the home.

(2) If the installation requires a design that is different from that provided by the manufacturer in paragraph (a)(1) of this section, the installation design and instructions must be prepared and certified by a professional engineer or registered architect, that have been approved by the manufacturer and the DAPIA as providing a level of protection for residents of the home that equals or exceeds the protection provided by the federal installation standards in part 3285 of this chapter.

(b) Providing instructions to installer. When the retailer or manufacturer agrees to provide any set up in connection with the sale of the home, the retailer or manufacturer must provide a copy of the approved installation instructions required in paragraph (a)(1) of this section or, as applicable, installation design and instructions required in paragraph (a)(2) of this section to each company or, in the case of sole proprietor, to each individual who performs set up or installation work on the home.
