Garage door rules & licensing in North Carolina

North Carolina Licensing Board for General Contractors — official site

G.S. 87-1 defines a 'general contractor' as 'any person or firm or corporation who for a fixed price, commission, fee, or wage, undertakes to bid upon or to construct or who undertakes to superintend or manage... the construction of any building, highway, public utilities, grading or any improvement or structure where the cost of the undertaking is forty thousand dollars ($40,000) or more.' The Board states: 'If a project is valued at $40,000 or more, your general contractor must have a license issued by the state.' Garage door work below $40,000 is not covered by this statute; there is no separate state garage door licence.

$40,000 - a general contractor licence is required where the cost of the undertaking is forty thousand dollars ($40,000) or more (G.S. 87-1).

G.S. 87-10 requires an applicant to 'Provide evidence of financial responsibility as determined by the Board.' The statute sets three licence limitations by single-project value: limited - up to $750,000; intermediate - up to $1,500,000; unlimited - 'act as general contractor without restriction as to value of any single project.'

G.S. 160D-1110(a) requires all permits under the North Carolina State Building Code before construction, reconstruction, alteration, repair, removal or demolition of any building or structure. But G.S. 160D-1110(c): 'No permit issued under Article 9 of Chapter 143 of the General Statutes is required for any construction, installation, repair, replacement, or alteration costing forty thousand dollars ($40,000) or less and performed in accordance with the current edition of the North Carolina State Building Code in any single-family residence, farm building, or commercial building' unless the work involves one of six listed items - and within the first of those, the statute expressly states: 'no permit is required for replacement of windows, doors, exterior siding, or the pickets, railings, stair treads, and decking of porches and exterior decks that otherwise meet the requirements of this subsection.'

NC Office of State Fire Marshal informal code interpretations confirm garage doors carry design-pressure requirements: 'Can DASMA Technical Data Sheet 155h be used for determining alternate design pressures for garage doors? Answer: Yes.' (2018 NC Residential Code, Table R301.2(6) and Table 4502(b)). A separate OSFM interpretation on NCRC R301.2.1.2 confirms windborne debris protection IS required for windows, doors and glazing in exterior walls of coastal dwellings, and that a like-for-like replacement leaving the existing frame is maintenance (not triggering the requirement) while replacing the frame is an alteration/renovation that must meet current code.
