North Carolina building inspector certification

Who needs a certificate

Under G.S. 143-151.13, nobody may do code enforcement under the article without a valid certificate from the board. The article defines code enforcement to include plan examination and inspection by employees of state and local government, by contractors working for them and by people doing third-party plan review (G.S. 143-151.8). It lists standard, limited and probationary certificates. A probationary certificate is for someone newly employed or newly promoted who lacks the prerequisites for a standard certificate, and the board's rules set its period, from one to three years.

Types of standard certificate

The statute lists building, electrical, mechanical, plumbing, fire and residential changeout inspector certificates. A holder may work only in the inspection area and level on the certificate. Level I, II and III certificates limit the types and sizes of buildings an official may approve, as set by the board's rules.

The exam

To get a standard certificate you pass an examination based on the state building code and the administrative procedures of code enforcement. The board may contract with others to build and give the exam. Under G.S. 143-151.16 the fee for that service is capped at $175. The statute does not say which exam a contractor gives or whether ICC exams are used, so ask the board.

Licensed architects, general contractors, plumbing or heating contractors, electrical contractors and professional engineers can receive a standard certificate after a short board course on the state code and code-enforcement administration (G.S. 143-151.13(f)). If you are still working toward the general contractor license, Bid Bond's guide to the NASCLA exam in North Carolina shows what NASCLA's list says about the state's general contractor board.

Comity

G.S. 143-151.14 lets the board grant a standard certificate without an exam to someone certified in good standing by a similar board in another state, or by the International Code Council, where the board finds the standards acceptable and not lower than its own. Those certificates expire after three years unless the holder completes a short board course. Whether a particular ICC certification qualifies is the board's call, so ask before you rely on it.

Fees and renewal

The statute sets caps: certification not more than $20, annual renewal not more than $10, and a late renewal charge of $4. A certificate renews each year on or before 1 July. If you fail to renew for two consecutive years, the board may make you pass the exam again. A certificate stays valid only while you are employed as a code enforcement official by the state or a local government (or tribal government), per G.S. 143-151.15. Check the board for the current fee schedule, since the board sets the actual amounts.

Where the B1 fits

The statute names ICC only in the comity route. For a North Carolina job, check with the board and the hiring department whether ICC exams count as preparation, as comity evidence or not at all. The B1 outline guide and B1 study guide help if you do take B1. ICC fees are in the ICC exam cost and scheduling guide.
