Building permits, zoning and septic rules in the Town of Seneca Falls, New York

The Town of Seneca Falls, New York has its own zoning local law1, but building permits come from Seneca County, not the town, because the county enforces the state Uniform Code inside the town2. Septic systems are reviewed by the Seneca County Health Department3. A town zoning permit is a separate step from the county building permit4.

Does the Town of Seneca Falls have zoning, and what does it mean for RVs, tiny homes and setbacks?

Yes. The Town of Seneca Falls adopted its own zoning law, officially the "Town of Seneca Falls Zoning Local Law," which sits in Chapter 300 of the town code1. Zoning, and therefore lot size, setbacks and what you may place on a lot, is decided by the town, not by Seneca County8.

We could not confirm what the town's zoning districts say about RV occupancy, tiny homes or temporary camping. Ask the town's Zoning and Code Enforcement office before you buy or park anything on a lot, and read the district use schedules in Chapter 300 of the town code1.

The zoning officer's duties include those generally assigned to the building inspector1.

Do you need a building permit in the Town of Seneca Falls, and who issues it?

Yes, for work that must conform to the New York State Uniform Code or Energy Code4. Inside the Town of Seneca Falls, Seneca County enforces that code, not the town2. Building permits are issued by Seneca County Code Enforcement in Waterloo9.

Some small work is exempt, such as certain one-story detached structures of 144 square feet or less, but exempt work must still meet the Uniform Code10. No work requiring a permit may start before the permit is issued10.

The county application asks for a copy of the town zoning permit when one applies, and a denied or rescinded town zoning permit means the county application is denied8.

How do septic permits work in the Town of Seneca Falls?

Seneca County, not the town, reviews septic plans. The Seneca County Health Department approves new, replacement and modified septic systems, and construction may not begin until the proposal is approved1112.

The application requires plans prepared by a Professional Engineer or Registered Architect, submitted in three stamped sets, with a residential application fee of $12511. A licensed engineer or architect must also inspect and certify the installation before it is covered13.

The town code has chapters on wells, cisterns and cesspools and on sewers; we could not confirm what they require, so ask the town before relying on a septic or well plan.

Building a home in the Town of Seneca Falls: the steps, in order

  1. Confirm with the town's Zoning and Code Enforcement office that your use and lot fit the zoning local law, and get a town zoning permit14.
  2. If you will subdivide, check the town's subdivision chapter first6.
  3. Apply to the Seneca County Health Department for septic approval if no public sewer serves the lot11.
  4. Apply for the county building permit, with a plot plan and the zoning permit copy14.
  5. Schedule inspections with the county 24 hours in advance, and request your certificate of compliance at the end1516.

What stays with Seneca County, and what to check before you buy in Seneca Falls

Building permits, construction inspections and septic review all stay with Seneca County even inside the town53. For land outside the town, see the Seneca County page.

Before buying, ask the county whether the parcel lies in a flood zone or wetland, because the building permit application asks and flood-hazard certification can be required before a certificate of occupancy17. Soil matters too: about 11.4% of soils in Seneca County rate "not limited" for a conventional drain field, so many lots need a site evaluation or an engineered system18. If the lot fronts a state highway, a driveway needs a state permit19.

Watch-outs

  • A town zoning permit and a county building permit are two separate approvals, and the county denies the building application if the town denies or rescinds the zoning permit8.
  • Seneca County accepts cash, money orders and checks for building permit fees, not credit cards20.
  • We could not confirm the town's rules for RV occupancy, tiny homes, wells, or septic inside the town; call the town's Zoning and Code Enforcement office and the Seneca County Health Department12.
