To the extent that any aspect of the installation is not provided for in the manufacturer's installation instructions, then the installation shall comply with applicable requirements of this code 24 CFR Part 3285 – Model Manufactured Home Installation Standards. In the case where the manufacturer's installation instructions for a manufactured home are not available, the NCSBCS/ANSI A225.1 standard, 1994 edition, may 24 CFR Part 3285 – Model Manufactured Home Installation Standards shall be substituted for the manufacturer's installation instructions. Foundations, stoops, decks, porches, alterations and additions associated with manufactured homes are subject to the requirements of this code and all administrative requirements of this code for permits, inspections and certificates of occupancy are also applicable. The requirements of the IRC shall be permitted to be used for the technical requirements for such construction work.

Skirting materials shall be durable, suitable for exterior exposures and installed in accordance with the manufacturer's installation instructions. Skirting shall be secured as necessary to ensure stability, to minimize vibrations, to minimize susceptibility to wind damage and to compensate for possible frost heave. Each manufactured home shall have a minimum of one opening in the skirting providing access to any water supply or sewer drain connections under the home. Such openings shall be a minimum of 18 inches (457 mm) in any dimension and not less than three square feet (.28 m²) in area. The access panel or door shall not be fastened in a manner requiring the use of a special tool to open or remove the panel or door.
