Off-Grid Living in Morris County, New Jersey

I'll be upfront: Morris County itself doesn't run zoning or building departments. New Jersey's Municipal Land Use Law puts that power in the hands of each of the county's 39 towns and townships, with the county filling in mostly on public health services (shared with many towns) and advisory planning review. So almost everything below comes down to "check your specific town," and I'll flag where that's true.

Zoning and raw land. There's no countywide zoning code. Each municipality writes its own zoning ordinance and map, and the Morris County Planning Board's role is mostly reviewing subdivisions and site plans, plus advising the county commissioners, not setting occupancy rules. If you're eyeing a parcel, you need that town's zoning office, not the county.

Tiny homes, RVs, alternative dwellings. I found no Morris County-wide rule here either, this is purely a municipal zoning call. Some towns are stricter than others about what counts as a permanent dwelling versus what's treated as a temporary structure or vehicle. Morris Township's zoning chapter is one example of how a town handles it, but it's not a countywide standard.

Building permits. New Jersey runs a statewide Uniform Construction Code, and each municipality's Construction Code Office is the one issuing permits, doing inspections, and signing off on certificates of occupancy. Morris County doesn't have its own building department for private construction. Expect your town to also require zoning and health sign-off before a building permit gets approved.

Septic and composting toilets. Local health departments (many under shared services with Morris County's Division of Public Health) issue septic permits under state rules for systems under 2,000 gallons a day. Morris County requires towns in watershed-sensitive areas to maintain septic maintenance programs, and some towns, like Parsippany, require licensing and proof of pumping. On composting toilets: state code explicitly does not treat outhouses, dry wells, or similar as approved septic systems, and restricts pit toilets and privies. So I would not assume a composting toilet is automatically legal here, it likely depends on how your local health officer interprets it. Ask before you build.

Greywater and rainwater. I couldn't find a Morris County or municipal ordinance addressing either one specifically. That leaves the state's general (and fairly vague) baseline in effect, so treat both as unclear until you get a direct answer from your town's health department.

Wells. Private wells are permitted, with local health department oversight. New Jersey's Private Well Testing Act requires water testing at time of sale, and towns encourage annual testing too, though routine annual tests don't substitute for the official sale-related testing.

Off-grid utility disconnection. No county or town law bans living without a utility hookup outright, but in practice getting a certificate of occupancy under the UCC usually requires an approved water supply and wastewater system, which loops back to your local building and health departments.

Bottom line: Morris County sets almost nothing directly. Your town's zoning office, construction code office, and health department are the three calls you actually need to make.
