(B) Roof. The manufactured home shall have a pitched roof with a slope not less than three feet in height for each 12 feet in width (14 degrees).
(C) Residential building materials. The manufactured home shall have exterior siding and roofing which in color, material and appearance are similar or superior to the exterior siding and roof material used on nearby residences (e.g., horizontal wood or wood-appearance siding is considered "superior" to metal siding and roofing).
(D) Garages and carports. The manufactured home shall have a garage or carport constructed of like materials when nearby residences have carports or garages. The city may require an attached or detached garage where that would be consistent with the predominant construction of immediately surrounding residences.
(E) Thermal envelope. The manufactured home shall be certified by the manufacturer to meet the thermal envelope requirements equivalent to those for a single-family dwelling constructed under the State Building Code.

Additional manufacturer's certification shall not be required.
(F) Placement. The manufactured home shall be placed on an excavated and back-filled foundation and enclosed at the perimeter such that the manufactured home is located not more than 16 inches above grade, and complying with the minimum set-up standards of the adopted State Administrative Rules for Manufactured Dwellings, Chapter 918. Where the building site has a sloped grade, no more than 16 inches of the enclosing material shall be exposed on the uphill side of the home.
