New Jersey Uniform Construction Code Shed Permit Exemptions

Under the State Uniform Construction Code Act (NJSA 52:27D-119 et seq.) and N.J.A.C. 5:23-2.14, detached one-story accessory structures used as tool or storage sheds with floor area not exceeding 200 square feet and no plumbing, gas, or electrical service are exempt from construction permits statewide. Municipalities cannot impose construction permit requirements stricter than the UCC, though zoning approval (setbacks, lot coverage) remains a separate local matter.

Building without a required UCC permit can result in penalties up to $2,000 per violation under N.J.A.C. 5:23-2.31, plus required removal or retroactive permitting.
