Buying Land in Salem County, New Jersey

New Jersey's smallest county, and a genuinely agricultural one

Salem County, in the far southwestern corner of New Jersey along the Delaware River, is the state's least-populous county by a wide margin -- just 65,874 residents as of a 2024 ACS estimate, spread across 331.9 square miles. That combination of low population and substantial land area produces a genuinely rural character, with farmland concentrated in the county's rural central and eastern sections; Alloway Township, for instance, is described as maintaining a roughly equal balance of family farms, woods, and quiet lakeside communities. This isn't a suburban county with scattered open lots -- it's one of South Jersey's most substantively agricultural counties, and its farmland market is covered in more depth in a dedicated standalone page linked below.

Salem County's distinctive backdrop: nuclear power and a bridge to Delaware

Two facts distinguish Salem County's land-use landscape from most other rural New Jersey counties. First, the Salem Nuclear Power Plant and Hope Creek Nuclear Generating Station -- both operated by PSEG Nuclear LLC, with Salem co-owned by Constellation Energy -- sit together on a 740-acre "Artificial Island" site in Lower Alloways Creek Township along the Delaware River, producing more than 40% of all electricity generated in New Jersey and more than 80% of the state's air-pollution-free generation. That's a major piece of regional energy infrastructure sitting inside an otherwise rural, agricultural county, and it shapes both the local tax base and the presence of associated infrastructure, easements, and emergency-planning zones in the surrounding area.

Second, Salem County is New Jersey's direct highway connection to Delaware: the eastern terminus of the Delaware Memorial Bridge sits in Pennsville Township, carrying I-295/US 40 traffic across the Delaware River to New Castle, Delaware. This makes Salem County genuinely cross-border-adjacent in a way most NJ counties are not -- worth noting for a buyer simply to be careful that any FIPS-coded records, tax data, or online searches pertain to Salem County, New Jersey (FIPS 34033) rather than being confused with a Delaware jurisdiction on the opposite riverbank.

Government, zoning, and septic

Salem County is governed by a five-member Board of County Commissioners, elected at-large to staggered three-year terms with either one or two seats up for election each year -- part of the statewide 2020 renaming from "Board of Chosen Freeholders." As everywhere in New Jersey, zoning remains a municipal function; the first call for any specific Salem County parcel is that township's or borough's own planning or zoning office.

For septic, the Salem County Department of Health and Human Services' Environmental Division directly handles permitting, plan review, and field inspection for new installations, alterations, and repairs countywide -- but it's worth knowing a specific, important limitation: the department does not inspect septic systems for real property transfers, and does not weigh in on disputes between a buyer and seller over a system's condition. A buyer relying on septic condition as part of a purchase decision should arrange for an independent, private septic inspection as part of due diligence rather than assume the county will provide that service.
