(2) Any changes in the structural design must be stamped by an engineer including:

(a) Fixed construction, which cannot be dismantled and stored. Such fixed construction must comply with the structural requirements of the state building code, for example, wind forces, seismic forces, snow load, live load, and dead load.

(b) Nonfixed construction which can be dismantled and stored for use when ice or snow exceed the snow loads stated in this chapter. Such nonfixed construction must comply with the structural requirements of the state building code, for example, wind forces, seismic forces, live load, and dead load with the exception of snow loads.
