New Jersey: Laws & Legal Considerations

Download all of New Jersey as PDF Print

New Jersey takes a hands-off approach at the state level, most of the practical regulation that exists happens at the county or municipal level instead.

RuleNew Jersey
Source water Rooftop or other catchment
Permit required No, for small-scale non-potable systems like standard rain barrels
Permitted uses Non-potable: irrigation, toilet flushing
Potable use Not permitted unless the system meets stringent state health standards
Local variation Counties and municipalities may add their own zoning, size, or installation-code requirements

Where to find it: the New Jersey Department of Environmental Protection (dep.nj.gov) for state guidance; your local municipality for any additional zoning or code requirements.

Water rights: riparian, plus a distinctive requirement for tidal waterfront

New Jersey follows ordinary riparian reasonable-use doctrine for its waterways, but its coastal geography adds a wrinkle most inland states don’t need: a specific state grant requirement for building on or using land that was historically underwater.

ConceptHow it works in New Jersey
Inland riparian rights Standard reasonable-use doctrine; rights are appurtenant to the adjoining land and can't be sold separately from it
Tidal waters and tidelands Held under the public trust doctrine; land seaward of the mean high water line is generally reserved for public use
Riparian grants A specific state grant from the NJDEP is required to build structures like piers or bulkheads on formerly tidal land, or otherwise claim rights to it

Why this matters more in New Jersey than most states covered so far

A lot of New Jersey’s current shoreline, especially around the Jersey Shore and Raritan Bay, sits on land that was once tidal and has since been filled or built up. Anyone buying waterfront property here specifically needs to check whether a riparian grant already exists or is required, a step that isn’t part of ordinary real estate due diligence in most inland states.

Where to find it: the NJDEP’s Bureau of Tidelands Management administers riparian grants.

Concealed carry: the most restrictive system covered on this site

New Jersey became a shall-issue state only after the Supreme Court’s 2022 Bruen decision forced it to drop its old discretionary standard, and the state responded with one of the most demanding permit processes and broadest carry restrictions covered anywhere on this site.

RequirementDetail
Standard Shall-issue since 2022, but with roughly 25 categories of legally off-limits locations added within days by Chapter 131
Minimum age 21
Character requirement "Good moral character" standard with four personal references required
Training required 16 hours, including live-fire qualification with a state-approved instructor
Cost $200 application fee
Purchase limit One handgun per 30 days, each requiring a separate Permit to Purchase
Magazine capacity Capped at 10 rounds

A restriction New York's CCIA doesn't have

New Jersey recognizes no other state’s concealed carry permit at all, full stop. New York’s CCIA, restrictive as it is, still participates in some reciprocity; New Jersey does not. Open carry is also strictly prohibited statewide. Combined with the ~25 sensitive-location categories, this makes New Jersey’s system the most restrictive covered on this site so far.
