Buying Land in Seneca County, New York

Government: a Board of Supervisors representing ten towns

Seneca County is governed by a Board of Supervisors -- the elected supervisor of each of the county's ten towns (Covert, Fayette, Junius, Lodi, Ovid, Romulus, Seneca Falls, Tyre, Varick, and Waterloo) sits on the board, with the current board seating fourteen supervisors total and using a weighted voting system based on each town's population. This is the traditional New York county-government model, distinct from the County Legislature structure used in some neighboring Finger Lakes counties. The board meets monthly, with committees overseeing county departments including Public Health, Human Services, Code Enforcement, and Planning.

The county's unusual two-shire arrangement -- Waterloo and Ovid have both been legal county seats since an 1822 resolution to that long-running north/south rivalry -- means the Board of Supervisors still meets at least once a year at the historic Ovid courthouse even though Waterloo now holds essentially all administrative offices. It's a genuine piece of the county's structure, but it doesn't change who to call about a specific parcel.

Zoning: town by town, with county-level referral review only

As in the great majority of New York outside the Adirondack Park, Seneca County itself has no zoning ordinance. Each town sets its own zoning map, permitted uses, and lot-size and setback requirements, and each administers its own building and zoning permits. The county's Planning & Community Development department reviews certain proposed local zoning and subdivision actions under General Municipal Law Section 239-m -- a coordination and advisory role over matters that could affect neighboring towns or countywide interests -- but this is not the same as a county having its own zoning authority. Confirm zoning district, permitted uses, and any minimum lot size directly with the specific town (Covert, Fayette, Junius, Lodi, Ovid, Romulus, Seneca Falls, Tyre, Varick, or Waterloo) before assuming a parcel's buildable status.

Septic: a real county Health Department process

Seneca County maintains its own county Health Department, which administers septic system permitting directly under the NYS DOH Appendix 75-A standard -- the statewide baseline for soil testing, tank sizing, and setbacks described on our septic systems guide. The county also runs its own Operation & Maintenance permit program for advanced/alternative treatment systems, requiring renewal roughly every five years with an associated fee. Confirm current permit fees and any county-specific submission requirements directly with the Health Department before assuming the statewide baseline is the only standard that applies.

A note on the former Seneca Army Depot

Buyers researching land in the towns of Romulus or Varick may come across parcels tied to the former Seneca Army Depot -- roughly 10,587 acres the U.S. Army fenced off in 1941 for munitions storage, closed under the 1995 federal base-closure process, and since transferred to the Seneca County Industrial Development Agency for redevelopment and resale, including a large tract sold at public bid in 2016 that today includes the privately run Deer Haven Park wildlife preserve (home to the depot's well-known herd of white deer). If you're looking at a parcel with any history tied to the former Depot, treat its unusual chain of title and any federal environmental closure/remediation record as a specific, non-generic due-diligence item -- verify directly with the Seneca County IDA and a title search rather than assuming it's a conventional private-land history.

Utility-scale solar in Waterloo and Junius: a state-run siting process

Northern Seneca County's flat, open farmland has attracted real, already-approved utility-scale solar development, not just developer interest: the 80-megawatt Trelina Solar Energy Center in the Town of Waterloo (approved 2021, built on land leased from Gem Lake Farms) and the 90-megawatt, roughly 827-acre North Seneca Solar Project spanning the Towns of Waterloo and Junius (final state siting permit issued August 21, 2025, with 32-year lease agreements executed across five landowners). Both were approved through the state's Office of Renewable Energy Siting (ORES) under Section 94-c -- a consolidated state review process for renewable facilities of 25 megawatts or more that can, in some cases, decline to enforce a specific local zoning provision it finds unreasonably burdensome, a materially different path than the standard 239-m town referral review described above.
