Off-Grid Living in Kings County, New York

Kings County is a special case for anyone researching off-grid living, because legally speaking, it doesn't function as a "county" at all. Kings County is coextensive with the Borough of Brooklyn, part of New York City, and there is no separate county planning office, building department, or health department here. Every rule that would normally come from a county comes instead from a New York City agency, applied the same way in Brooklyn as in the other four boroughs.

That matters a lot if you're dreaming of an off-grid homestead. Brooklyn is a fully urbanized, essentially 100% sewered borough. The infrastructure and legal framework here were built for dense city living, not rural self-sufficiency, and I want to be upfront that most of what off-gridders do in a rural county is either heavily restricted or not documented as a viable path in Brooklyn.

Zoning and raw land: There's no county zoning code. The NYC Zoning Resolution, administered by the NYC Department of City Planning, governs land use everywhere in Brooklyn, and simply occupying vacant land off-grid isn't a recognized use under that resolution.

Dwellings, tiny homes, RVs: I could not confirm any Kings County or NYC carve-out for tiny houses on wheels or RVs as permanent residences. Any habitable structure has to comply with the NYC Construction Codes and zoning occupancy rules, administered by the NYC Department of Buildings (DOB).

Building permits: NYC has its own construction code stack (Title 28 of the NYC Administrative Code), which supersedes the New York State Uniform Fire Prevention and Building Code. DOB's Brooklyn borough office handles permits and inspections for Kings County projects.

Septic and composting toilets: Since Brooklyn is almost entirely served by the city's combined sewer system, septic is rarely used and where it exists it needs sign-off from both DOB and the New York State Department of Health. I found nothing confirming composting toilets as a legal substitute for sewer connection in NYC.

Greywater and rainwater: Simple outdoor rain barrels appear to be fine, regulated separately by the NYC Department of Environmental Protection (DEP) rather than needing a DOB permit. But any indoor reuse of greywater or rainwater, like flushing toilets, falls under the NYC Plumbing Code and requires a DOB construction permit plus Department of Health and Mental Hygiene (DOHMH) review.

Private wells: I found no official source describing an active path to permit a new residential drinking-water well in Brooklyn. The borough runs on the city water system operated by DEP, and drilling a private well here isn't documented as a real option.

Utility disconnection: I didn't find any provision letting a dwelling in Kings County legally disconnect from city water and sewer. Sewer connection certification requirements point the other direction, toward mandatory hookup.

Bottom line: if full off-grid independence is the goal, Kings County / Brooklyn is about the hardest place in New York State to attempt it legally, and you should verify every specific plan directly with the city agencies below before assuming anything is allowed.
