What it takes to build here — permits, zoning, and septic — scouted from Salem County’s own official sources.
New Jersey's statewide Uniform Construction Code requires a construction permit before building, enforced at the municipal level by the local construction official (not the county).
NJ DCA - The New Jersey State Uniform Construction Code ↗Zoning in New Jersey is delegated exclusively to municipalities under the Municipal Land Use Law; Salem County itself does not zone (county planning board handles subdivision/site-plan review only).
New Jersey Municipal Land Use Law (N.J.S.A. 40:55D) ↗County Health Department Environmental Division reviews applications and issues permits for individual subsurface sewage disposal (septic) systems under N.J.A.C. 7:9A.

Whether a new home can legally get its own water here — the sub-state groundwater regime, from New Jersey’s water agency.
The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.
No allocation permit for a household well below ~70 gpm even inside the Water Supply Critical Areas; the critical-area cutbacks applied to large public purveyors, not domestic wells. A NJDEP well-construction permit is still required (50,000 gpd threshold in the Highlands Preservation Area).
Limit: < 100,000 gal/day (~70 gpm)
NJDEP — Water Allocation ↗Designated 1993; PRM withdrawals capped at the 1983-1991 maximum, public-supply pumping cut ~22%, and new PRM water-supply allocations prohibited within the depleted margin. Domestic wells (<100,000 gpd) are exempt.
NJDEP (NJ Critical Area No. 2) / USGS ↗Regulated-riparian state (large uses permitted). Groundwater rules change and basin boundaries follow the aquifer, not the county line — confirm current well and appropriation rules with the New Jersey state water agency before you buy or drill.Groundwater governance as of Jul 2026, cited to each administering agency.
