Do you need a building permit in North Greenbush, New York?

Yes. Inside the Town of North Greenbush, no one may begin work that requires a building permit without first getting one from the Code Enforcement Officer1. The town administers the New York State Uniform Fire Prevention and Building Code and the Energy Code through Chapter 75 of its code8. Applications are written, on a form the Code Enforcement Officer provides or accepts, and signed by the owner or an authorized agent9. Fees are set by the Town Board and due with the application10.

New York allows a town to exempt some small work, such as certain one-story sheds and playhouses, but an exemption never excuses code violations11. Ask the Building Department what North Greenbush exempts before you skip a permit. We could not confirm an owner-builder exemption in the town code, so assume a permit is needed.

Who issues building permits in North Greenbush, and how do you reach them?

The Town of North Greenbush Building Department issues building permits, including for new construction, alterations, decks, sheds and swimming pools, and issues certificates of occupancy once permitted work is finished5. The office is at Town Hall, 2 Douglas Street in Wynantskill5. The town, not Rensselaer County, runs building permits here. Work must stay exposed until the Code Enforcement Officer inspects it12, and a certificate of occupancy is required for work done under a building permit6.

Does North Greenbush have zoning?

Yes. The town divides its land into 17 zoning districts, and the official zoning map is the final authority on where each district begins and ends2. Rensselaer County has no countywide zoning, so the town code, enforced by the Building Department, is what governs a lot inside town limits35. Check the map and the district's rules before you buy.

We could not confirm the town's rules on RV occupancy, camping, tiny homes, accessory dwellings or a minimum house size. Ask the Code Enforcement Officer in writing for the lot's district before you plan any of them.

How do septic permits work in North Greenbush?

The Rensselaer County Public Health Engineering Division reviews plans for individual wastewater treatment systems, typically prepared by a New York licensed professional engineer, and inspects new and replacement systems13. Under the county sanitary code, no one may build or alter a sewage outlet until the Department grants a written permit4. Unusual system types need a specific waiver4.

Soils matter: only about half a percent of the county's soils rate as not limited for a conventional drain field, so expect a site evaluation and possibly an engineered system14. We could not confirm how the town's sewer connection rules apply to a particular lot, so ask the Building Department whether public sewer is available.

Building a home in North Greenbush: the steps, in order

  1. Ask the Building Department which zoning district the lot is in and what that district allows2.
  2. If the lot is near water, confirm with the Building Department whether it lies in the special flood hazard area, where a development permit is required first7.
  3. Where there is no public sewer, have a professional engineer design the septic system and submit it to the county Public Health Engineering Division13.
  4. Apply for the building permit from the Code Enforcement Officer1.
  5. Call for inspections as each stage is ready and keep work exposed until inspected12.
  6. Obtain the certificate of occupancy before moving in6.

What stays with Rensselaer County, and what to check before you buy

Septic permits come from Rensselaer County, not the town15. Land outside North Greenbush is covered by whichever town or city it sits in; the Rensselaer County page has the county-level picture. Rensselaer County's effective property tax rate is 2.2% and its median property tax bill is $5,357 a year1617. We could not confirm a town rule on private wells or driveway permits, so ask the Building Department and the town highway office before you buy.

Watch-outs

  • We could not confirm whether North Greenbush has an owner-builder exemption, so call the Building Department before starting owner-performed work5.
  • We could not confirm the town's rules for RVs, tiny homes, accessory dwellings or private wells; ask the Code Enforcement Officer before buying with one of those in mind5.
  • Septic plans must be approved by the county before any new or altered system is built4.
