Cal. Code Regs. tit. 25, § 1338
(a) Except as provided in section 1338.1 of this article, every MH-unit installed shall have the capacity to resist the applicable minimum roof live load of the region in which it is installed as set forth in Table 1338-1 or as is further provided by this section. Table 1338-1 shall apply except where either greater or lesser snow loads have been established through survey of the region, and approved by the department. Except as described in Section 1338.1, below, at elevations above 4,000 ft., snow loads established for residential buildings by local ordinance shall apply.
(b) When an application is submitted for a permit to install an MH-unit manufactured prior to October 7, 1973, or an MH-unit with a designed roof live load less than that specified in Table 1338-1 and it is known the MH-unit will be subjected to snow loads, the plans and specifications shall include a method of protecting the MH-unit from snow loads that is acceptable to the enforcement agency.
When approved by the enforcement agency, a ramada may be used to protect an MH-unit which does not have the capacity to resist the minimum roof live load for the region in which it is to be installed. The ramada shall be designed to resist the minimum roof loads for the region in which it is constructed and shall be constructed pursuant to the provisions of section 1486.
(e) The park owner or operator shall maintain the snow roof load maintenance program, as long as units in the park do not meet the minimum roof loads for the area.
