Off-Grid Living in St. Lawrence County, New York

St. Lawrence County is a strange animal for anyone chasing off-grid life: there's no countywide zoning code at all. Land use authority in New York is handed down to local municipalities, and here that means 40 of the county's 47 towns and villages have adopted some form of land use rules, while 7 have none. So the honest first step, before I tell you anything else, is: find out which of the 47 you're actually in, because that determines almost everything else in this guide.

Zoning and raw land. Whether you can just buy acreage and live on it with minimal oversight depends entirely on your town. Some towns run subdivision regs, setbacks, and density rules; others have nothing on the books. The county Planning Office keeps a status list by municipality, and I'd start there before assuming anything.

Dwellings, tiny homes, RVs. I found no countywide rule on this. It's a town-by-town call. Where a town has no zoning, there's often no local barrier to living in an RV or tiny home full-time. Where a town does have zoning, expect it to lean on the state's general treatment of RVs and THOWs as travel trailers, not permanent dwellings, unless the local code says otherwise.

Building permits. The county doesn't issue building permits itself. Individual towns, villages, or cities do that through their own code enforcement offices, all operating under the state's Uniform Fire Prevention and Building Code as a floor.

Septic and composting toilets. This one actually is countywide. The St. Lawrence County Public Health Department administers a Sanitary Code covering wastewater permitting, and there's a septic replacement assistance program for eligible properties near priority waterbodies, though the county expects the property owner to arrange their own engineer and contractor. Composting toilets weren't addressed specifically in what I found, so I'd confirm treatment of alternative systems directly with Public Health.

Greywater and rainwater. No county-specific ordinance on either. My assumption is these default to the state baseline, greywater reuse fairly restricted, rainwater harvesting generally allowed for non-potable use, but I'd call the county Public Health Department to confirm nothing local overrides that.

Wells. Drilling itself is a state matter (DEC-registered drillers required), and the county doesn't permit the drilling, but St. Lawrence County Public Health does offer water-quality testing and recommends annual well inspection and bacteria testing.

Utility disconnection. Because zoning is optional town by town, there's no countywide mandate to hook into grid power or municipal water/sewer. Towns without zoning generally can't require it; towns with zoning might.

Bottom line: this is a county where your rights depend heavily on your specific town line, so don't skip that homework.
