Ocean County, NJ Landscaping Rules: Rainwater Harvesting (2026)

Rainwater collection in Ocean County is permitted for residential non-potable use without state restrictions. New Jersey's Water Supply Management Act (N.J.S.A. 58:1A) does not restrict residential rainwater collection for garden irrigation, lawn watering, or other non-potable uses. Typical 50-60 gallon rain barrels do not require permits in Toms River, Brick, Jackson, Lakewood, or LBI municipalities. Large cisterns (generally 1,000+ gallons) may trigger building permits under NJ UCC N.J.A.C. 5:23 if structurally mounted or connected to plumbing. Barnegat Bay Partnership actively promotes rain barrels and offers workshops/rebates through partner municipalities as a nonpoint-source pollution reduction strategy. Some Ocean County municipalities participate in the Rutgers Cooperative Extension Water Resources Program rain barrel workshop rebate. HOAs and condo associations — common in 55+ communities like Leisure Village, Holiday City, Greenbriar — may restrict visible rain barrel placement. Potable use of harvested rainwater requires NJDEP drinking water treatment approval (rare for residential). Plumbed connections to indoor fixtures require plumbing subcode permit and backflow prevention. Drought declarations by NJDEP do not restrict private harvested rainwater use.
