Off-Grid Living in Salem County, New Jersey

I've spent a fair amount of time digging through Salem County, New Jersey's government pages, and the honest headline is this: Salem County itself doesn't zone land or regulate dwelling types. That authority sits with each of the county's 15 municipalities under New Jersey's Municipal Land Use Law. The county government's real jobs here are septic permitting, well permitting, and a countywide wastewater management plan, all run through the Salem County Department of Health and Human Services. So anything I tell you about zoning or what kind of structure you can live in has to come with a big asterisk: confirm with your specific town.

Zoning and raw land. There's no countywide zoning ordinance. Each township or borough, from the City of Salem to the rural farming townships, sets its own rules under the state's Municipal Land Use Law. The county Planning Board mostly reviews subdivisions and publishes a growth-management framework, but that's advisory, not binding zoning.

Tiny homes and RVs. I found nothing at the county level addressing tiny homes or RV living directly. This is entirely a municipal zoning-code question. As an example of how granular it gets, the City of Salem's residential zone sets a minimum lot area per dwelling, which shows how dwelling-type rules live in local code books, not county documents.

Building permits. Construction permitting runs through your municipality under the state's Uniform Construction Code, with the state DCA doing inspection oversight in some towns. There's no county-level building department.

Septic. This is squarely a county function. The Salem County Department of Health and Human Services reviews and permits septic systems against state standards (NJAC 7:9A), and yes, a homeowner can self-install a system but there's a process to follow through the county. Composting toilets specifically aren't addressed on the county's site, so I'd call and ask directly.

Greywater and rainwater harvesting. I couldn't find any Salem County or state guidance specifically on these. Treat both as unclear until you get a direct answer from the county health department or your town.

Wells. Wells are a two-step deal: NJDEP issues the initial permit, then you submit that to the county for your county well application. Worth noting, Salem is one of the New Jersey counties where mercury testing is specifically required under the Private Well Testing Act, on top of the standard panel, so budget for that extra test.

Utilities. No countywide ordinance forces a utility hookup, but occupancy approval generally expects an approved water source and sewage method, meaning your well and septic permits effectively substitute for "hookups." Even here there's local variation. The City of Salem, for instance, doesn't require a Certificate of Occupancy before a title transfer, which won't be true everywhere.

Bottom line: for anything zoning or dwelling-related, find out which of the 15 municipalities your land sits in and call that office first. For septic and wells, the county health department is your one-stop shop.
