Off-Grid Living in Orleans County, New York

If you're looking at raw land in Orleans County, New York, the first thing I want you to understand is that Orleans County itself doesn't zone anything. There is no countywide zoning code. Zoning is set town by town, ten separate towns (Albion, Barre, Carlton, Clarendon, Gaines, Kendall, Murray, Ridgeway, Shelby, Yates), each with its own ordinance, most hosted on eCode360. The county's Planning & Development Department reviews town zoning actions when towns amend their codes (about fifty referrals a year), but it doesn't write or enforce the rules on your parcel. That means the honest answer to almost every "can I do X" question here is: it depends which town you're in, and you need to pull that town's zoning ordinance or call its code enforcement officer.

Building permits work the same way. There was a 1988 county local law dealing with the Uniform Fire Prevention and Building Code, but actual permitting is done by town-level code enforcement officers, not a county building department. A county legislator has even floated whether the county should take over code enforcement from towns, and the response so far has been "if towns are happy with the current system, leave it alone." So expect to deal with a town code enforcement officer, not a county office, for permits.

Where the county DOES have real authority is public health, specifically septic and wastewater. That's handled by the shared Genesee-Orleans health department, GOHealthNY, which reviews and approves septic systems for new construction under New York State's sanitary code standards. I saw this cross-referenced directly in Town of Albion zoning code, which requires county health department sign-off before building. Well water similarly falls under the same environmental health office and state Department of Health baseline rules, though I did not find an Orleans-specific well permitting ordinance beyond standard state driller registration.

Greywater reuse, rainwater harvesting, tiny homes, and RVs as dwellings: I could not confirm any county-specific rules on these in official sources. They likely default to whatever the state baseline is (New York doesn't have strong statewide greywater reuse permitting, and rainwater collection for non-potable use is generally fine) combined with whatever your specific town's zoning code says about accessory structures and minimum dwelling size. Don't assume; call the town.

Living off-grid, disconnected from utilities, is the same story: no countywide rule I could find. The Town of Orleans requires zoning and building permits before you build at all, which suggests other towns have similar gatekeeping, but whether any town mandates a grid hookup for a permanent residence wasn't confirmed. Ask the specific town's code enforcement officer.

Bottom line: for zoning and building, your town is the authority. For septic and water quality, the county health department is the authority. Confirm both before you buy or build.
