Union City, NJ Landscaping Rules: Rainwater Harvesting (2026)

New Jersey imposes no restrictions on residential rainwater collection, making Hudson County a rain-harvesting-friendly jurisdiction. Standard 50-55 gallon rain barrels can be installed without permits for non-potable use including garden irrigation, vegetable watering, and container plants. Jersey City actively promotes rain barrels through its MS4 (Municipal Separate Storm Sewer System) Stormwater Program and has distributed subsidized or free rain barrels at public events and Earth Day programming. Hoboken has historically distributed free rain barrels to residents and runs workshops through the Hoboken Environmental Services Department — especially important given Hoboken's flood-prone SW quadrant. The Rutgers Cooperative Extension of Hudson County runs periodic 'Rain Barrels and Rain Gardens' workshops. Large cisterns (over 200 gallons or structurally connected to roof systems) may trigger a building permit under NJ UCC N.J.A.C. 5:23 and plumbing permit if connected to household systems. Potable use of collected rainwater is regulated by NJ Department of Health and requires filtration/treatment to meet drinking water standards — very rarely pursued residentially. HOA and condo associations in newer developments may restrict visible barrel placement. Rain gardens and bioswales count toward stormwater management requirements for new construction.
