Read this before you act on anything below. This is my researched starting point for Sussex 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 rulesSussex County, NJ

Zoning & raw-land occupancy

Varies locallyNo countywide zoning code exists; the Sussex County Planning Board only handles subdivision, site-plan, and land-development review. Actual zoning and lot-occupancy rules are set by each of the 24 municipalities. source

Dwellings, tiny homes & RVs

Unclear - verifyNo Sussex County ordinance on tiny homes or RV occupancy was found; this is set at the municipal level, so confirm with your town's zoning office.

Building permits & codes

Generally allowedBuilding permits are issued by each municipality's construction office enforcing the state Uniform Construction Code; the county only hears appeals via its UCC Board of Appeals. source

Septic & composting toilets

Generally allowedThe Sussex County Office of Environmental Health administers septic permitting under state standards (N.J.A.C. 7:9A) and requires a 100-foot separation from wells; composting toilets aren't separately addressed and would need health department review. source

Greywater reuse

Unclear - verifyNo Sussex County ordinance or health department guidance on greywater reuse was found; not confirmed, ask the county Division of Health before installing a system.

Rainwater harvesting

Unclear - verifyNo county-specific rule on rain barrels or cisterns was found; not confirmed, likely falls under the general state baseline of no dedicated permit requirement.

Private wells & water rights

Generally allowedWell permits are issued by the Sussex County Division of Health, with setback and design standards following state code; a well cannot be covered by any structure. source

Living disconnected from utilities

Unclear - verifyNo county ordinance mandates connection to public utilities, but a Certificate of Occupancy generally still requires an approved water supply and sewage system verified through the county's septic/well process. source
