A.
Skirting and permanent perimeter enclosures will be
installed within 30 days of placement of the manufactured home. Skirting,
if used, shall be durable materials suitable for exterior exposures.
Skirting must not be attached in a manner that can cause water to
be trapped between the siding or trim to which it is attached. The
skirting should be recessed under the siding or trim. The building
code does not permit wood, including lumber and all wood siding used
for skirting, to be used within six inches of the ground unless it
is pressure treated to prevent decay and termite infestations.
B.
The space beneath the home shall be provided with
a sufficient number of ventilation openings to ensure ample ventilation.
The total net area of ventilation openings must be a minimum of one
square foot for each 150 square feet of the home's floor area. One
ventilation opening shall be within three feet of each corner of the
home. When a uniform six-mil polyethylene sheet material or other
acceptable vapor barrier is installed on the ground beneath the home
to further reduce moisture, the total net area of ventilation openings
may be reduced to one square foot for each 1,500 square feet of the
home's floor area.
C.
Access opening(s) not less than 18 inches in any dimension
and not less than three square feet in area shall be provided and
shall be located so that any water supply and sewer drain connections
located under the home are accessible for inspections.
D.
Dryer vents, air-conditioning condensation drains
and combustion air inlets must pass through the skirting to the outside.
