Read this before you act on anything below. This is my researched starting point for Somerset County, NJ, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

The local rulesSomerset County, NJ

Zoning & raw-land occupancy

Varies locallySomerset County has no countywide zoning code; zoning is set individually by each of the 21 municipalities, and the County Planning Board mainly reviews land development affecting county facilities or roads. source

Dwellings, tiny homes & RVs

Unclear - verifyNo county-level rule addresses tiny homes or RV occupancy specifically; this is governed by each municipality's zoning code plus the statewide Uniform Construction Code baseline.

Building permits & codes

Generally allowedBuilding permits are issued locally by each municipality's Construction Office under New Jersey's statewide Uniform Construction Code; there is no single county building portal. Franklin Township's Construction Code office is one example of how a municipal office operates. source

Septic & composting toilets

Generally allowedSeptic systems are governed by New Jersey's statewide standards (N.J.A.C. 7:9A), with permitting handled by municipalities and, for many towns, the Somerset County Department of Health. Primitive pit toilets, cesspools, and outhouses are restricted under state rule, not simply allowed. source

Greywater reuse

Unclear - verifyNo Somerset County or municipal ordinance specifically addressing residential greywater reuse was found; this is not confirmed and likely falls to state DEP rules on larger-scale reuse only.

Rainwater harvesting

Unclear - verifyNo Somerset County or municipal rule specifically permitting or restricting residential rain barrels or cisterns was found; treat this as inheriting the state baseline, which does not appear to require a permit for typical residential use.

Private wells & water rights

Generally allowedPrivate wells are permitted statewide, but Somerset is one of the counties where New Jersey's Private Well Testing Act requires an added uranium test; the Somerset County Department of Health promotes testing and can answer well questions. source

Living disconnected from utilities

Unclear - verifyNo standalone Somerset County rule requires connection to public utilities; Certificate of Occupancy requirements are set by each municipality under the state UCC and generally expect an approved water source and sewage disposal method.
