WAC 296-150I-0300
Who establishes standards for
installation of manufactured homes? (1) The director of labor
and industries is responsible for establishing uniform
installation standards where possible and practical for
persons or entities engaged in performing the installation of
manufactured homes within the state.
(2) Local jurisdictions may adopt additional installation
requirements only for those installation situations not
covered by federal standards. For example, local
jurisdictions may impose noise control construction
ordinances, prescribe the frost depth and soil bearing
capacity at the installation site, and adopt requirements to
protect manufactured homes in hazardous areas (see WAC 296-150I-0310).
Also, local jurisdictions may impose their requirements
for snow loads as long as all structures within their
jurisdiction are required to comply with the same standard and
provided those installing the manufactured home are given
options in satisfying that standard. Such an option might
include, but not be limited to, allowing an installer to erect
an additional structure, which meets local standards, and
protects the manufactured home. For example, an installer
could erect a free standing ramada over a manufactured home to
protect it from local snow loads.
Local jurisdictions may not:
(a) Dictate foundation design and construction which is
built according to either the manufacturer's installation
instructions or a design created by an engineer or architect
licensed in Washington state.
(b) Impose regulations on smoke detectors because they
are regulated by federal standards.
