Jersey City permit rules — NJ UCC framework

Jersey City enforces the New Jersey Uniform Construction Code (UCC) — NJAC 5:23 — administered by the local Construction Code Office at One Jackson Square. The NJ UCC adopts the 2021 International Codes with NJ amendments, creating a statewide baseline that all municipalities enforce consistently. Unlike Ohio's no-state-license residential environment, New Jersey requires NJ HIC (Home Improvement Contractor) registration from the NJ Division of Consumer Affairs for all contractors performing more than $500 in home improvement work — one of the lowest thresholds in the country. Trade work (plumbing, electrical, HVAC) requires separate NJ trade licenses.

PSE&G serves Jersey City for both gas and electric. PSE&G's mandatory yellow sticker inspection is the most significant Jersey City permitting distinction from other cities in this guide: before PSE&G restores gas service after any gas work, a PSE&G inspector must visit the property, verify the gas system is safe, and affix a yellow approval sticker. This applies to furnace replacements, water heater changes, kitchen appliance conversions — any work that required the gas to be turned off. No yellow sticker means no gas restoration. Plan the PSE&G inspection into the project timeline.
