§ 1336.2. Installation Requirements for a Tiedown System Consisting of Listed Tiedown Assemblies.
Currentness
The installation of a tiedown system consisting of listed tiedown assemblies shall comply with the requirements of this section.
(a) Unless otherwise specified in the MH-unit manufacturer's installation instructions, the number of tiedown assemblies that must be installed for each longitudinal side of an MH-unit shall be determined by dividing the wind load calculated as required in section 1336 by the working load of the listed tiedown assembly chosen for use.
(1) The quotient shall be rounded up to equal the number of listed tiedown assemblies required for each longitudinal side.
(2) The working load of the listed tiedown assembly used in the calculations, shall be calculated for one-thousand five-hundred (1,500)-psf soil, consisting of clay, sandy clay, silty clay and clayey silt, as classified in the California Residential Code, Table R401.4.1.
(b) The number of tiedown assemblies required pursuant to subsection (a) may be reduced to no less than two (2) under the following circumstances:
(1) If the MH-unit's installation instructions provide for a reduction in the number of tiedown assemblies and for the subsequent, concentrated amount of resistance at specific points on the MH-unit; and
(2) if engineered data is submitted to and approved by the enforcement agency which substantiates a different class of materials constituting the soil into which the anchor is to be inserted, as provided in the California Building Code, Table 18-1-A.
(c) No less than two (2) tiedown assemblies shall be installed at each end of each transportable section of the MH-unit. The working load of the tiedown assemblies installed at each end of an MH-unit shall be the same as the working load of the tiedown assemblies installed along each of the longitudinal sides of the MH-unit.
(d) It is the responsibility of the contractor/installer to determine the location of all underground utilities within the MH-unit's lot, such as gas, water, sewer, electrical or communications systems, and to avoid the location of all underground utilities when choosing the specific location for the insertion of each ground anchor. The location of each anchor shall not violate the clearance requirements from underground utilities adopted by the Public Utilities Commission in General Order 128, pursuant to section 768 of the Public Utilities Code.
(e) If the MH-unit manufacturer's installation instructions are available and provide for the installation of a tiedown system, listed tiedown assemblies shall be installed as follows:
(1) The number of tiedown assemblies and the manner of attachment and location of the attachment of the tiedown assemblies to the MH-unit shall be as required by the installation instructions provided by the manufacturer of the MH-unit and by subsection (c); and
(2) The listed tiedown assemblies shall be installed as required by their listing and by subsections (a)(2), (h) and (j).
(f) If the installation instructions provided by the MH-unit's manufacturer do not provide for the installation of a tiedown system or if the MH-unit manufacturer's installation instructions are not available, all tiedown assemblies shall be installed as required by their listing and by this section.
(g) The required tiedown assemblies shall be spaced as evenly as practicable along the length of each side and end of the MH-unit, with no more than two (2) feet of open-end spacing at any end of the MH-unit, measuring from the point of the attachment of the tie to the MH-unit.
(h) No portion of the tiedown assembly shall extend above the ground beyond the vertical plane of the side or end wall of the MH-unit.
(i) A tie shall be wrapped around a main structural frame member and shall not attach to a steel outrigger beam that fastens to and intersects a main structural frame member.
(j) After the tie is connected with the MH-unit and to the ground anchor, the tie shall be drawn tight to eliminate all slack.
