Permit Fees
New Jersey deck builders work under the 2021 IBC/IRC with NJ amendments as the Uniform Construction Code (UCC); 2024 IBC/IRC adoption proposed (amendments filed October 2025). New Jersey requires building permits for virtually all construction work through the statewide Uniform Construction Code (UCC) administered by the Department of Community Affairs (DCA). All home improvement contractors must register with the Division of Consumer Affairs and display their NJHIC number. Licensing is handled by the New Jersey Division of Consumer Affairs — Home Improvement Contractor Registration, and homeowners can cross-check a contractor before hiring. On the exemption side: ordinary maintenance and minor repairs. A New Jersey-specific rule most homeowners miss: new Jersey has a mandatory statewide Uniform Construction Code (NJAC 5:23) administered by the Department of Community Affairs. The Newark and Jersey City permit portals handle the bulk of New Jersey deck permit submissions — if your project is in one of those cities, start there.
