Overview
Do you need a New Jersey code official license?
Yes, if you enforce the New Jersey Uniform Construction Code (UCC). Code officials, inspectors and plans examiners working for a municipality, county or other local enforcing agency need a state license for each subcode and building class they cover.
License required when
- You run a local code enforcement department as a code official
- You inspect construction sites as a building, electrical, fire protection or mechanical inspector
- You review construction documents as a plans examiner
- You work for a municipality, county or government agency that has adopted the State codes
Common exceptions
- An ICS (Industrial and Commercial Structures) electrical license doesn’t cover one- and two-family homes; residential work needs a separate license
- A fire protection ICS license covers plan review for Class II and III structures only; plan review for Class I structures needs the HHS (Highrise-Hazardous) license
- A current New Jersey architect or engineer license can stand in for the experience requirement for some classes, but not for the exams
Working without the right license
Our sources don’t list specific penalties. Only licensed people can perform UCC inspections and plan reviews, and the Department of Community Affairs can deny, suspend or revoke a license.
