Off-Grid Living in Niagara County, New York

I'll be upfront: Niagara County itself doesn't zone land. There's no countywide zoning code here, so whether you can live off-grid on a piece of land in Niagara County depends almost entirely on which city, town, or village that land sits in. The county's real regulatory muscle is in environmental health, meaning septic systems, wells, and water supply. Let me walk through what I found.

Zoning and dwellings. Each municipality, the Town of Niagara, City of Niagara Falls, City of Lockport, North Tonawanda, Lewiston, and the rest, writes and enforces its own zoning ordinance. The Niagara County Planning Board only plays an advisory/referral role on certain actions under New York State General Municipal Law, mostly for things near municipal boundaries or with intercommunity effects. So there's no single answer for "can I put a tiny house or RV on my land here." I looked at the Town of Niagara's code as an example: it permits single-family dwellings as the principal use in residential districts and treats small accessory structures (under 200 square feet) separately, but doesn't list RVs or tiny homes on wheels as permitted principal dwellings. You need to check with the specific town or city zoning office.

Building permits. Same story, town-by-town. Each municipality has its own building or code-enforcement department applying the New York State Uniform Fire Prevention and Building Code locally. The City of Niagara Falls and Town of Niagara both have their own inspection offices; there's no county-level building department that overrides them.

Septic. This is where the county steps in directly. The Niagara County Health Department enforces the Sanitary Code of the Niagara County Health District, and nobody may build, alter, or extend a sewage disposal system in the district without written approval from the Public Health Director. Niagara is also one of the minority of New York counties that requires a septic inspection at property transfer, so if you're buying land with an existing system, budget time for that.

Greywater and rainwater. I couldn't find county-specific rules on either. Absent a local restriction, the state baseline likely applies, but I'd call the county Environmental Health office directly before setting up a greywater system, since the Sanitary Code's wastewater chapter is written broadly enough that it might reach greywater too.

Wells. The Niagara County Health Department handles well approvals and coliform testing (not chemical testing) and signs off on private water supply for property transfers, which require a ten-day usage test. Well contractors themselves must be registered with the state DEC under Environmental Conservation Law.

Utilities. No county law forces a grid or municipal-water hookup. But you can't get a certificate of occupancy without a Health-Department-approved water and septic system, and each town enforces the state Uniform Code for electrical and heating hookups. Off-grid is workable here, but the path runs through your town's building department and the county Health Department, not around them.
