Off-Grid Living in Steuben County, New York

Steuben County, New York is a big, rural patchwork of towns, and if you're eyeing off-grid land here, the first thing I have to be honest about is: this county does things a little differently than most. I've dug through the official Steuben County and New York State pages, and here's what I found.

Zoning is not a county-level thing here. Steuben County itself doesn't impose zoning; the county Planning Department only weighs in on certain local actions under state law (General Municipal Law Section 239-m), like zoning changes, variances, and site plans near boundaries. Whether your target parcel has zoning at all depends entirely on the town, some have adopted it, some haven't. The county keeps a map of which municipalities have zoning, planning boards, and subdivision rules, so before you assume raw land is unrestricted, call the town.

Building permits are required countywide, but administered town by town. Steuben County's Local Law #6 of 2006 sets the framework requiring a building permit for construction, alteration, or installation of things like chimneys and heating devices, and each town has its own Code Enforcement Officer who reviews applications (they have up to 30 days) and can issue civil penalties for violations. So the rulebook is countywide in spirit, but enforcement is local.

For tiny homes and RVs, I didn't find a Steuben-specific ordinance. This falls back to the town's code enforcement officer applying the NYS Uniform Fire Prevention and Building Code, and the general state assumption that RVs and THOWs aren't treated as permanent dwellings outside of parks. Confirm with your specific town CEO.

Here's the quirk that matters most for septic and wells: Steuben County has no county health department. Environmental health services, including septic system permitting and well water guidance, come from the NYS Department of Health Hornell District Office, which covers both Steuben and Schuyler counties. Septic systems need to meet the state's standard design requirements (Appendix 75-A), and there's no stricter county add-on that I found. For well water testing, the county FAQ page points people to the Hornell District Office and to certified labs (fees vary by lab).

Greywater reuse and rainwater harvesting don't have Steuben-specific rules that I could locate, so both default to the New York State baseline, greywater tends to be more restricted/limited under state plumbing rules, while rainwater harvesting is generally allowed.

Utility disconnection (going fully off-grid electrically) isn't addressed at the county level. Since building code enforcement is town-based, whether you're required to hook up to the grid is a town-by-town question, not a countywide law.

Bottom line: Steuben County sets some countywide building permit framework, but zoning, dwelling rules, and utility requirements are decided by your specific town, and septic/well matters go through a state office rather than a county health department. Call ahead before you buy or build.
