-3: End Wall Marriage Line Gap Photographs and Skirting Installation of
Factory-Built Homes
Factory-Built homes shall not be skirted until a duly authorized representative of the Factory-
Built Home Division of the State Fire Marshal's Office has inspected the set-up. An inspection
of the home is usually scheduled to occur within seven (7) to ten (10) business days following
the receipt of the Property Locator/Certificate of Installation from the retailer, the developer
and/or the installer/transporter and may be extended to allow for unexpected shortages in
manpower and resources.
Effective July 1, 2026, the installer/transporter is required to obtain photographs of the
marriage line at the ends of the assembled multi-section residential units/homes (inclusion of
the serial number of the home and a visual measurement (using a tape measure or ruler) of the
widest portion of the marriage line gap is required)) prior to installing the end wall siding, and
is required to submit those photographs to the retailer and to the State Fire Marshal’s office
attached to the property locator/certificate of installation form. Any gap at the end walls of the
marriage line exceeding 1 inch in width is not acceptable and will delay the inspection. Some
filler material (APA rated sheathing (OSB or Plywood) not to exceed ½ inch thickness) are
allowed in areas that exceed the one (1) inch allowable gap. The connections along the marriage
line and any filler material used, for all new homes, to reduce the gap must be in compliance
with the manufacturer’s installation manual.
The connections along the entire marriage line must be corrected to the 1 inch or less in width
for the compression of the gasket to provide the proper seal and pass the State inspection.
Marriage line gap widths that are not properly closed up will increase the potential for air
infiltration from the exterior and/or attic space of the home resulting in an increase in moisture
condensation levels inside the home.
If, at the time of the installation inspection, the skirting on the Factory-Built home has already
been installed, it will be necessary to reschedule the inspection until such time that all skirting
has been removed for an unobstructed view of the entire underside of the home. The person(s)
removing the skirting shall be responsible for contacting the State Fire Marshal’s Office when
the home is ready for the inspection to be conducted. A second inspection fee will be assessed by
the retailer for each occurrence of the skirting having been installed prior to the State Fire
Marshal inspection.
Prior to the installation of the skirting on any Factory-built home, it shall be the responsibility of
the either the retailer and/or installer to contact the State Fire Marshal’s office for confirmation
that the installation inspection has been completed and a decal has been placed on the home.
