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.

The local rulesCape May County, NJ
Zoning & raw-land occupancy
Varies locallyCape May County has no countywide zoning; each of the 16 municipalities sets its own land-use rules under the state Municipal Land Use Law. The County Planning Board only reviews certain referred site plans and subdivisions. source
Dwellings, tiny homes & RVs
Unclear - verifyNo county-level rule on tiny homes or RV occupancy was found; this is set town by town alongside the state Uniform Construction Code's dwelling classification. Ask the specific municipal zoning/construction office.
Building permits & codes
Generally allowedMunicipal construction offices issue permits under the state-adopted Uniform Construction Code, but almost the entire county lies in the state's CAFRA coastal zone, so many projects also need NJDEP coastal review in addition to local approval. source
Septic & composting toilets
Generally allowedThe county's Environmental Services Department, acting under the state County Environmental Health Act, oversees septic design and inspection, including alternative systems for difficult sites. State rules also say outhouses and dry wells don't count as septic systems. source
Greywater reuse
Unclear - verifyNo county ordinance on residential greywater reuse was found; this isn't addressed distinctly and inherits New Jersey's general lack of a dedicated residential greywater code.
Rainwater harvesting
Unclear - verifyNo Cape May County ordinance or guidance on rain barrels or cisterns was found; if regulated at all, it would likely be through a municipal stormwater ordinance, not a county rule.
Private wells & water rights
Generally allowedNJDEP regulates well construction statewide, and Cape May County is one of the counties with an added mercury-testing requirement under the state's Private Well Testing Act, with results routed through the local health authority. source
Living disconnected from utilities
Unclear - verifyNo county ordinance requiring utility hookup was found; occupancy approval is issued by the municipal construction office and generally presumes an approved water supply and sewage system are in place, which an off-grid well-and-septic setup can potentially satisfy.
