Tree removal permit rules in Union County, NJ — sometimes called heritage tree, protected tree, or street tree ordinances — list which trees require a permit before you can cut them down.
NJDEP requires all NJ municipalities to adopt tree removal-replacement ordinances as part of MS4 stormwater permit compliance (since Nov. 2022). Individual municipalities set permit requirements and replacement ratios.
Union County tree removal regulations protect the urban canopy by requiring permits for trees above a size threshold, typically 6 to 12 inches trunk diameter measured at breast height (4.5 feet). Applications may require an arborist report. Street trees in the right-of-way are managed exclusively by Union County public works or urban forestry. Dead, dying, or hazardous trees may qualify for expedited removal. Replacement planting is usually required. New Jersey state law may preempt local tree ordinances in certain circumstances.
Unauthorized removal: $500 to $10,000 per tree. Replacement planting required. Street tree damage: city restitution costs.
