Steuben County, New York does not zone; zoning is set town by town, and the county's Planning Department only reviews certain municipal zoning actions in an advisory role1. Steuben County itself issues building permits only for the Towns of Addison, Campbell, and Tuscarora; every other town runs its own code enforcement office, so confirm which applies to your parcel2. Septic here is not handled by a county health department; the New York State Department of Health's Hornell District Office covers Steuben (and Schuyler) County instead3.

Do you need a building permit in Steuben County, New York?
Almost certainly yes, but who issues it depends on your town: Steuben County itself provides building-permit code enforcement only for the Town of Addison, Town of Campbell, and Town of Tuscarora, on behalf of those towns24. Every other town in Steuben County runs its own code enforcement office rather than using the county's, so confirm with your specific town before assuming the county handles it2. Statewide, New York requires a building permit for any work that must conform to the Uniform Code or Energy Code, with narrow exemptions such as small detached storage sheds under 144 square feet and minor finish work7. Whichever office issues your permit, expect inspections during construction and a certificate of occupancy before you can legally use or occupy the finished building86.
Who issues building permits in Steuben County, and how do you reach them?
For the Towns of Addison, Campbell, and Tuscarora, Steuben County's code enforcement office reviews building permit applications, with up to 30 days to issue a decision once you apply4. Reach that office by phone, or mail your application and permit-fee payment to Steuben County Public Works at 3 E Pulteney Square, Bath, NY 14810, payable to the Steuben County Commissioner of Finance4. If your land is in any other Steuben County town, the county will not process your permit; contact that town's own code enforcement or building department instead. The Steuben County Planning Department can point you toward the right local contact and reviews certain zoning actions those towns take, but it does not issue building permits itself9.
Does Steuben County have zoning?
No: Steuben County itself does not zone, because zoning in New York is a town and village function, not a county one1. The county's Planning Department exists to support that town-level system, providing technical assistance and training to local boards and reviewing certain local zoning and planning actions under General Municipal Law Section 239-m, rather than writing or enforcing zoning rules of its own9. That means whether you can build a particular size of home, place an RV, or add an accessory dwelling depends entirely on the zoning code of the specific town where your parcel sits, and some Steuben County towns may have no zoning at all while others do; you must check with the town directly1. If your town's planning board reviews subdivisions, New York law lets the town board authorize that review for land outside any village, with statutory deadlines around 62 days for key steps10.
How do septic permits work in Steuben County?
Septic systems in Steuben County are not permitted through a county health department, because Steuben does not deliver environmental health services that way; instead, the New York State Department of Health's Hornell District Office covers environmental health, including onsite wastewater, for Steuben and Schuyler Counties311. Statewide, a septic system serving less than 1,000 gallons per day of ordinary sewage does not need a state SPDES discharge permit, but approval may still be required from the city, county, or state district health office before you build, and that is exactly the Hornell District Office's role here5. Because New York's soil-limitation data for this county shows essentially no soils rated free of severe limits for a conventional drain field, plan on a site evaluation and likely an engineered or alternative system rather than a standard drain field before you commit to a lot12.
Can you live in an RV or tiny home on your land in Steuben County?
Because Steuben County has no county zoning, whether you can live in an RV or a tiny home on your own parcel is decided entirely by the zoning code of the town your land is in, not by the county1. Some Steuben County towns have adopted zoning and some have not, so you have to ask your specific town, not the county, whether long-term RV living or a tiny home is allowed and under what conditions19. Any dwelling you place still needs the applicable building permit, either from the county's code enforcement office if you are in Addison, Campbell, or Tuscarora, or from your own town's office everywhere else24. It will also need an approved wastewater plan, whether that is a septic system reviewed through the state's Hornell District Office or a connection to an approved sewer system3.
Building a home in Steuben County: the steps, in order
- Identify your town and find out whether it is one of the three towns (Addison, Campbell, Tuscarora) where Steuben County issues building permits, or whether your own town's code enforcement office does24.
- Ask that same town, not the county, what its zoning code allows for your lot, since Steuben County itself does not zone1.
- Contact the New York State Department of Health's Hornell District Office to start your septic review if you are not on a sewer system11.
- Submit your building permit application to the correct code enforcement office; if it is one the county handles, expect up to 30 days for a decision4.
- Pay your permit fee and complete required inspections as work proceeds, since New York requires inspections for permitted construction statewide8.
- Obtain your certificate of occupancy before you move in or use the building, since New York law only permits occupancy after that certificate is issued6.
What to check before you buy land in Steuben County
Confirm which town your parcel is in and call that town directly about zoning and building permits, since Steuben County has no countywide zoning and issues building permits itself for only three towns12. Budget for a real septic evaluation: this county's soils show essentially none rated free of severe limits for a conventional drain field, so an engineered or alternative system is a realistic possibility on many lots12. Steuben County is genuinely rural, sitting about 56 miles from the nearest city of 100,000 or more people, with population density around 66 people per square mile1314. Farmland here has recently sold for roughly $3,076 an acre on average, and the effective property tax rate is about 2.5%, with a median annual tax bill near $3,245, so factor that carry cost into your budget151617. If you plan to subdivide, remember that plat approval runs through the town planning board, not the county, when the town has authorized that review10.
Watch-outs
- Do not assume Steuben County issues your building permit: the county only provides that service for the Towns of Addison, Campbell, and Tuscarora; every other town has its own code enforcement office24.
- Steuben County has no zoning of its own; a Steuben County answer about setbacks, RVs, or minimum lot size does not exist because those rules live entirely at the town level1.
