Off-Grid Living in Hudson County, New Jersey

Hudson County, New Jersey is a strange place to research off-grid living, and I want to be upfront about why: it's the most densely urbanized county in the state, it's fully carved into incorporated municipalities (Bayonne, Hoboken, Jersey City, Kearny, North Bergen, Secaucus, Union City, Weehawken, West New York, Guttenberg, Harrison, East Newark), and there's no unincorporated land left over. That single fact shapes almost every answer below.

Zoning. The Hudson County Division of Planning exists mainly to support the Hudson County Planning Board with coordination and technical review, it does not zone land itself. Zoning authority sits with each municipality. So whether you can put a tiny structure on a lot, or what setbacks apply, comes down entirely to that town's zoning office, not the county. I'd start with your specific municipality's code, not a county code, because there isn't one for this.

Dwellings, tiny homes, RVs. I found no Hudson County rule on this. It's a municipal zoning and construction-code question, same as the state baseline generally leaves it. Different Hudson County cities will treat a tiny home on wheels or long-term RV occupancy very differently, so check with the town directly.

Building permits. These are issued by each municipality's construction department (Hoboken, Jersey City, Bayonne, North Bergen, Secaucus, etc.), all enforcing New Jersey's statewide Uniform Construction Code. The county doesn't run a building department, so there's no county-level permit to chase here.

Septic and composting toilets. This is where Hudson County is genuinely unusual: it's almost entirely on public sanitary sewer, and I found no county ordinance or program addressing septic permitting. If you somehow had an unsewered parcel, the applicable authority would likely be the Hudson Regional Health Commission or a city's own health department (Jersey City has its own), but this is not confirmed as an active program here. Practically speaking, going off-grid on sewage in this county is not something the local rules anticipate.

Greywater and rainwater harvesting. I didn't find any Hudson County or municipal ordinance on either. Status is unclear, and I'd treat this as inheriting the state's general framework until a town official tells you otherwise.

Private wells. Not confirmed, and likely inapplicable in practice, since the county runs on public water systems. No local well-permitting program turned up in my research.

Utility disconnection. No specific Hudson County or municipal standard on living fully off-grid utilities was found. New Jersey's general construction code expects connected water and sewer for a certificate of occupancy, and nothing I found suggests Hudson County towns depart from that.

Bottom line: this is one of the hardest places in New Jersey to go meaningfully off-grid, not because of one big prohibition, but because the infrastructure and the rules assume you're plugged into city services. Every real answer runs through your specific municipality's zoning and construction offices.
