Agency Contact: Stephen W. Calhoun, Regulatory Coordinator, Department of Housing and Community Development, The Jackson Center, 501 North 2nd Street, Richmond, VA 23219-1321, telephone (804) 371-7000, FAX [phone], TTY [phone], or email [e-mail].

Summary:

The amendments update the Uniform Statewide Building Code to incorporate by reference the recent changes and additions to the Federal Construction Standards of the United States Department of Housing and Urban Development (HUD). The Federal Construction Standards are enforcement provisions for the design, construction, distribution, and installation of manufactured homes. As of October 2008, HUD instituted manufactured home installation standards as part of its enforcement procedures to be the standard for the installation of manufactured homes in all states. The amendments to the Uniform Statewide Building Code allow the Commonwealth of Virginia to adopt Installation Standards of HUD Part 3285 as the most current installation standard available.

13VAC5-63-220. Chapter 4 Special detailed requirements based on use and occupancy.

A. Add Section 407.8 to the IBC to read:

407.8 Special locking arrangement. Means of egress doors shall be permitted to contain locking devices restricting the means of egress in areas in which the clinical needs of the patients require restraint of movement, where all of the following conditions are met:

2. The building is equipped with an approved automatic sprinkler system in accordance with Section 903.3.1.1.

3. A manual release device is provided at a nursing station responsible for the area.

4. A key-operated switch or other manual device is provided adjacent to each door equipped with the locking device. Such switch or other device, when operated, shall result in direct interruption of power to the lock -- independent of the control system electronics.

C. Change Section 408.2 of the IBC to read:

408.2 Other occupancies. Buildings or portions of buildings in Group I-3 occupancies where security operations necessitate the locking of required means of egress shall be permitted to be classified as a different occupancy. Occupancies classified as other than Group I-3 shall meet the applicable requirements of this code for that occupancy provided provisions are made for the release of occupants at all times. Where the provisions of this code for occupancies other than Group I-3 are more restrictive than the provisions for Group I-3 occupancies, the Group I-3 occupancy provisions shall be permitted to be used.

Means of egress from detention and correctional occupancies that traverse other use areas shall, as a minimum, conform to requirements for detention and correctional occupancies.

Exception: It is permissible to exit through a horizontal exit into other contiguous occupancies that do not conform to detention and correctional occupancy egress provisions but that do comply with requirements set forth in the appropriate occupancy, as long as the occupancy is not a high-hazard use.

421.2 Site work for manufactured homes. The installation of a manufactured home is generally subject to the requirements of the Virginia Manufactured Home Safety Regulations (13VAC5-95). Under those regulations, the building official is responsible for assuring that the installation complies with the manufacturer's installation instructions and any special conditions or limitations of use stipulated by the label. 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. In addition, Appendix E of the IRC entitled, "Manufactured Housing used as Dwellings," shall be an acceptable alternative to this code for construction work associated with the installation of manufactured homes and for additions, alterations and repairs to manufactured homes.

N. Add Section 421.4 to the IBC to read:

421.4 Skirting requirements for manufactured homes. As used in this section, "skirting" means a weather-resistant material used to enclose the space from the bottom of the manufactured home to grade. Manufactured homes installed or relocated shall have skirting installed within 60 days of occupancy of the home. 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. On-site fabrication of the skirting by the owner or installer of the home shall be acceptable, provided that the material meets the requirements of this code.

O. Add Section 421.5 to the IBC to read:

421.5 Site work for industrialized buildings.

To the extent that any aspect of the erection or installation of an industrialized building is not covered by those regulations, this code shall be applicable. In addition, 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 any construction work that is subject to this code where the industrialized building would be classified as a Group R-5 building.
