(7) Residential-type Framing Activities. For the purposes of this section, residential-type framing activities include: installation of floor joists, floor sheathing, layout and installation of walls, hanging and nailing of shear panels, setting and bracing roof trusses and rafters, installation of starter board, roof sheathing, and fascia board; installation of windows, siding and exterior trim. The limited use of structural steel in a predominantly wood-framed home, such as steel I-beam to help support wood framing, does not disqualify a structure from being considered residential-type construction. Residential-type framing activities includes framing of commercial structures that use traditional wood frame construction materials and methods.
