    • Uses not expressly permitted are prohibited (§ 223-4a), so zoning districts and uses must be read from the schedules.

    Construction inside Union City city, under the statewide New Jersey Uniform Construction Code (UCC) as enforced by the city's municipal code enforcement staff.

    • The UCC is a state code. Union City enforces it through municipally employed, state-licensed officials; no city-specific code adoption was found in the opened pages.
    • Local amendments, if any, were not checked.
    “who enforces it in new jersey, state-licensed, municipally employed code enforcement professionals-construction officials, subcode officials, and inspectors--are responsible for the enforcement of the ucc.”
