North Carolina draws a bright line at the project price: cross it without a license and the contract is unenforceable. It also runs one of the country's more unusual lien systems, built around online lien agents. Here is the 2026 version.
Licensing: the $40,000 threshold
A general contractor license from the NC Licensing Board for General Contractors is required for any project of $40,000 or more, with limited ($1M project cap), intermediate ($3M) and unlimited tiers tied to working capital and exams. Electrical contractors are licensed by the State Board of Examiners of Electrical Contractors, and plumbing, heating and fire sprinkler contractors by their own state board, at any dollar value for most work. Confirm current thresholds with the boards, but plan on licensing early: NC courts will not enforce payment claims for unlicensed work above the line.
Liens: the LiensNC lien agent system
On most private projects of $40,000 or more, the owner designates a lien agent through LiensNC, and anyone wanting lien protection should file a Notice to Lien Agent within 15 days of first furnishing. The claim of lien itself must be filed within 120 days of last furnishing and perfected by suit within 180 days. Subcontractors also have subrogation and funds-lien routes with their own notices. The system is genuinely digital and cheap to comply with, which removes the usual excuse.
Workers comp, tax and OSHA
Workers compensation applies at three or more employees, with the usual GC flow-down pressure below that. North Carolina taxes repair, maintenance and installation (RMI) services on existing property, while real property contracts (capital improvements) follow a contractor-pays-tax-on-materials model with Form E-589CI documenting the difference, a distinction worth getting right on every invoice. Safety is enforced by the NC Department of Labor's OSH division under a full state plan.

North Carolina FAQs for trade businesses
Is the license threshold per contract or per project?
Per project cost, $40,000 or more, and splitting contracts to duck it does not work. Confirm the current figure with the board, then license for the tier matching your project sizes.
What is a lien agent and why should I care?
On most $40,000+ private projects the owner appoints a lien agent via LiensNC, and filing your Notice to Lien Agent within 15 days of starting preserves your lien rights. It takes minutes online and skipping it is the most common NC lien failure.
What is RMI tax?
North Carolina taxes repair, maintenance and installation services on existing property, while capital improvement contracts follow the contractor-pays-on-materials model documented with Form E-589CI. Every invoice should know which side it is on.
