Summary
Onslow County Code § 5-1(a) adopts the North Carolina Building Code, Residential Code and related state construction codes by reference, word for word, to control every improvement built within the county's planning jurisdiction. The Planning and Development Department administers and files the codes and any amendments the state adopts.
(a)State building codes adopted by reference. The following North Carolina regulatory codes and their appendices, as adopted by the North Carolina Building Code Council pursuant to N.C.G.S. § 143-138, are hereby adopted by reference and shall control construction and installation of improvements within the planning jurisdiction of the County as if set forth herein word for word, except as amended or modified in this Chapter:(1)North Carolina Building Code (2002 and 2006 editions).*...(6)North Carolina Residential Code (2002 edition).
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 10).
Full Breakdown
§ 143-138. Subsection (b) separately adopts the federal Manufactured Home Construction and Safety Standards and the state's 2004 manufactured home regulations for manufactured housing installed in the county. Subsection (c) makes later amendments to any referenced code effective in the county's planning jurisdiction automatically, as soon as the amendments are filed with the Planning and Development Department, and subsection (d) requires that department to keep an official copy of every adopted code and amendment on file for public reference. Because the county folds its construction standards directly into this general Code rather than a separate building code chapter, a permit applicant in the unincorporated county is building to these state codes as referenced here, plus whatever the Building Code Council has updated since. The schedule of building permit fees is kept on file with the county clerk's office rather than printed in the code itself.
Violations & Fines
Section 5-1 itself sets no standalone penalty, so building without a permit or work that does not conform to the adopted state codes falls under the Code's general penalty in section 1-6: a fine of up to $500 or imprisonment for up to six months per offense, with each day the violation continues charged as a separate offense.
