Building permits, zoning and septic rules in the Town of Union Vale, New York

Building in the Town of Union Vale, Dutchess County, New York takes a building permit from the town's Code Enforcement Officer1. Union Vale adopted its own zoning code, so lot, use and setback questions are answered by the town, not the county2. Septic and well plans are reviewed by the Dutchess County Department of Behavioral & Community Health before the town issues the permit3.

Does Union Vale have zoning, and what does it mean for RVs, tiny homes, lot size and setbacks?

Yes. The Town of Union Vale adopted its own zoning, so the town decides what you can build and where, and Dutchess County does not2. Dutchess County itself has no county zoning; land-use rules are set by each city, town and village9. The town's zoning code publishes a district schedule of area and bulk rules, separate use schedules for residential and commercial districts, and a zoning map4. Minimum lot size, setbacks, building height and lot coverage differ by district, so find the parcel's district on the zoning map before you price a house or outbuilding. We could not confirm the town's rules on RV occupancy, tiny homes, accessory dwellings, manufactured homes or short-term rentals, so ask the Building/Zoning Department7 before you plan to live in anything other than a permitted house. Dutchess County's zoning map is for general reference only and sends district questions back to the town10.

Do you need a building permit in Union Vale, and who issues it?

Yes. Under the Town of Union Vale code, no one may construct, enlarge, alter, relocate or demolish a building, or install a solid-fuel heating appliance or chimney, without first getting a building permit from the Code Enforcement Officer1. The town enforces the New York State Uniform Code, which applies in every part of the state outside New York City11. Exemptions exist for certain small detached structures, minor work and specified repairs, and New York State allows a town to exempt one-story detached sheds up to 144 square feet; confirm the town's exact list before you skip a permit112. The permit application is written on a form acceptable to the Code Enforcement Officer and signed by the owner or an authorized agent13. The town's code sets the fee; we could not confirm the amount, so ask the office14. Work must stay exposed until the officer inspects it, and a certificate of occupancy is required before use156.

How do septic permits and wells work inside Union Vale?

The town does not run its own septic program. The town code requires the water supply and wastewater systems proposed with a building permit to conform to the regulations of the New York State and Dutchess County Departments of Health5. Dutchess County's Department of Behavioral & Community Health has jurisdiction over onsite wastewater systems, and the state health department also has jurisdiction16. In practice, the town has you complete part of the county's septic form, the building inspector sends it to the county, and the county recommends the building permit only after file review and a pre-construction conference3. Lot approval needs a New York State-licensed Professional Engineer17. Anyone constructing or abandoning a water well needs a county permit18. Across Dutchess County only a small share of soils rates as not limited for a conventional drain field, so expect a site evaluation and possibly an engineered system19. We could not confirm a Union Vale-specific septic inspection rule beyond the county's.

Building a home in Union Vale: the steps, in order

  1. Find the parcel's zoning district on the town zoning map and confirm your use is allowed there4.
  2. Hire a licensed Professional Engineer for lot approval and septic and well design, and submit it to the county health department17.
  3. Apply to the Code Enforcement Officer for a building permit on the town's form; the town starts the county septic form with you1320.
  4. Wait for the county's file review and pre-construction conference; the county recommends the permit only if no problems turn up3.
  5. If the driveway meets a public road, get the driveway or work permit from the proper jurisdiction (the town, the county or the state)21.
  6. Keep work exposed for inspections and call the officer when each stage is ready15.
  7. Have the county inspect the septic system or well before it is covered, then obtain the certificate of occupancy226.

What stays with Dutchess County, and what to check before you buy in Union Vale

Septic and well approvals, and subdivision water and sewer approvals, stay with the Dutchess County Department of Behavioral & Community Health23. Subdivision maps must also be filed with the Dutchess County Clerk to be valid17. For land outside Union Vale, use the Dutchess County page. Before you buy, ask the Building/Zoning Department to show the property file; the office urges sellers to review it, and its title rules require an interior inspection for a transfer or refinance, with a title fee of $350.007. Check road frontage: a driveway onto a state highway needs a New York State Department of Transportation permit24. Flood zones are regulated locally and the town's rule is unconfirmed, so ask the Code Enforcement Officer25. Dutchess County's effective property tax rate is about 2%8, and the county's wooded share of land is about 82%26.

Watch-outs

  • The title fee for a sale or refinance includes an interior inspection and is $350.00, so schedule it well before closing7.
  • We could not confirm Union Vale's rules on RVs, tiny homes, accessory dwellings, minimum lot sizes or setbacks; get the district rules from the Building/Zoning Department before you buy7.
  • Septic and well plans can stop a building permit: if the county's pre-construction inspection finds unexpected soil conditions or plan errors, no building permit will be recommended3.
  • We could not confirm whether Union Vale has an owner-builder permit exemption beyond its statement that owners may do their own work with a notarized statement7.
