(A) A single-family modular home manufactured after January 1, 2005, must meet the following standards to be certified for placement in this State:
(1) Roof pitch. For homes with a single predominant roofline, the pitch of the roof must be at least five feet rise for every twelve feet of run;
(2) Eave projections. The eave projections of the roof must be at least ten inches, not including a gutter around the perimeter of the home unless the roof pitch is at least seven feet rise for every twelve feet of run;
(3) Exterior wall. The height of the exterior wall must be at least seven feet six inches for the first story;
(4) Siding and roofing materials. The materials and texture of the exterior materials must be compatible in composition, appearance, and durability to the exterior materials commonly used in standard residential construction.
(B) A single-family modular home placed in the State after January 1, 2005, must meet the foundation requirements provided by the State in this subsection:
(1) A perimeter wall located under the exterior walls of the home, whether load-bearing or nonload-bearing, must be constructed of brick, masonry, or other permanent material commonly used in standard residential construction, consistent with surrounding residential structures, and in accordance with the International Residential Code as adopted by the South Carolina Department of Labor, Licensing and Regulation. All modular manufacturers shall submit with the plan set for each building to the department's Modular Buildings Program a minimum foundation design.
(2) A home located in a coastal or flood plain area may require piling or other special foundation designs. These foundations must be designed by a registered professional engineer or architect and are subject to review and approval by the local jurisdiction and not by the Modular Buildings Program. A perimeter wall constructed of brick, masonry, or other materials to enclose the foundation of the home may be a requirement of the design.
(C) An appeal for a variance from a certification standard or a foundation requirement described in this section may be taken in the same manner as provided in Section 23-43-120.

(3) it has not been altered from its original design;
(4) it was manufactured within five years before the placement for first residential use; and
(5) the seller provides the purchaser with written notice that the home meets the appropriate code requirements in effect at the time of manufacture, and may or may not meet the code requirements in effect at the time of placement for residential use.
