Building permits, zoning and septic rules in Greene County, New York

#27 of 62 in New York

In Greene County, New York, work subject to the state Uniform Code requires a building permit from the code enforcement officer in the town or village where the property lies1,2. Zoning approval is also municipality-specific, while the NYSDOH Oneonta District Office handles environmental health services, including septic matters, throughout the county3,4.

Do you need a building permit in Greene County, New York?

Yes.

Yes. Work in Greene County that must conform to the New York Uniform Code requires a building permit, subject to permitted exceptions1. The Uniform Code is automatically in effect in each city, town and village, and local governments generally administer and enforce it1. Apply to the code enforcement officer in the town or village where the building is located, not to Greene County Planning2. A local enforcement program may exempt a qualifying one-story detached shed or playhouse no larger than 144 square feet, but exempt work must still comply with the state codes8. Ask the municipal code officer which building-permit application, plans and supporting approvals your project requires.

Who issues building permits in Greene County, and how do you reach them?

The town or village code enforcement officer issues the local building permit and is the first contact for the application, inspections and certificate of occupancy.

The town or village code enforcement officer issues the local building permit and is the first contact for the application, inspections and certificate of occupancy2,6. Greene County Planning can help identify municipal zoning resources, but it does not replace the local building or zoning office3. Fees also depend on the municipality: the Town of Cairo's current schedule charges residential building permits at $0.30 per square foot with a $50 minimum9. Septic approval does not move to the town or village building department; the NYSDOH Oneonta District Office conducts Greene County environmental health services4. Contact Greene County Public Health at (518) 719-3600 for the state-office referral4.

Does Greene County have zoning?

Greene County does not apply one uniform zoning map: zoning is administered by the relevant town or village, and the county publishes links to municipal codes.

Greene County does not apply one uniform zoning map: zoning is administered by the relevant town or village, and the county publishes links to municipal codes3. The county identifies Ashland, Durham, Hunter and Prattsville as towns without zoning, but the absence of zoning does not remove building-permit, septic or floodplain requirements1,3,10. Where zoning exists, lot size and setbacks can differ sharply by district. In Cairo, minimum lot size ranges from one-quarter acre with both municipal water and sewer to two acres with neither service11. In Catskill's RA district, the minimum lot is 1.5 acres and the setbacks are 50 feet front, 30 feet side and 100 feet rear12. Confirm the parcel's municipality and zoning district before using any dimensional figure.

How do septic permits work in Greene County?

Septic-system plans in Greene County require health-authority approval before construction.

Septic-system plans in Greene County require health-authority approval before construction5. The NYSDOH Oneonta District Office conducts environmental health services for all Greene County addresses because Greene County Public Health is a partial-service department4. That septic authority remains separate even when a town or village issues the building permit and administers zoning. Only about 0.9% of Greene County soils are rated without severe limitations for a conventional septic drain field, so make site and soil feasibility an early purchase condition13. Ask the state health district which application, site testing, design and inspections apply to the exact parcel; we could not confirm one ordinary residential septic application procedure. A proposed realty subdivision may trigger additional state health review when it creates 5 or more residential lots of 5 acres or less within a 3-year period14.

Can you live in an RV or tiny home on your land in Greene County?

We could not confirm one countywide rule allowing residential RV or tiny-home occupancy in Greene County.

We could not confirm one countywide rule allowing residential RV or tiny-home occupancy in Greene County. Zoning and allowed uses vary by town or village, while the state building code and septic approval remain separate requirements1,3,5. A Cairo rule describes an RV used in a campground as temporary living quarters for recreation, education or vacation, but that rule does not establish a general long-term RV right on private land outside a campground15. A tiny home intended as a dwelling may need a local building permit for work subject to the Uniform Code and a certificate of occupancy before use1,6. Ask the municipal code officer about the proposed use, parking, dimensional rules and occupancy, and ask the NYSDOH Oneonta District Office about wastewater.

Building a home in Greene County: the steps, in order

Identify the town or village containing the parcel because building permits and zoning approval are municipal.

  1. Identify the town or village containing the parcel because building permits and zoning approval are municipal2,3.
  2. Ask the local zoning or code office to confirm the district, allowed residential use, setbacks, minimum lot size, application documents and fees3.
  3. Obtain health-authority approval for the septic-system plans before construction; the NYSDOH Oneonta District Office handles Greene County environmental health services4,5.
  4. Apply to the municipal code enforcement officer for the building permit2.
  5. Call for required building inspections and leave covered work accessible until it is inspected and accepted6.
  6. Obtain the certificate of occupancy or compliance before occupying the completed permitted work6. A county homeowner electrical permit is narrow and does not exempt a new house from this process7.

What to check before you buy land in Greene County

Confirm the parcel's town or village, zoning district, allowed use, building-permit route and municipal fee schedule before relying on a listing description.

Confirm the parcel's town or village, zoning district, allowed use, building-permit route and municipal fee schedule before relying on a listing description2,3. Test septic feasibility early because only about 0.9% of county soils are rated without severe limits for a conventional drain field13. If the parcel lies in a FEMA-mapped Special Flood Hazard Area, private development requires a local floodplain development permit, usually administered by the municipal building inspector or code officer10. A residence on a state highway needs an NYSDOT driveway permit to build or modify its driveway; ask the local road authority about access from other roads because we could not confirm one countywide driveway-permit rule16. For a private well, use a registered contractor who will notify the state before drilling and file the completion report afterward17.

Watch-outs

  • Building permits, zoning approval and septic approval come from different authorities: the municipality handles building and zoning, while the NYSDOH Oneonta District Office handles environmental health and septic matters2,3,4.
  • A fee, setback or lot-size rule from Cairo, Catskill or Tannersville does not apply across Greene County; use the rule for the parcel's municipality and zoning district9,12,18.

  • InspectionsRequired

    Construction work for which a building permit has been issued and which is subject to the Uniform Code or Energy Code, administered by the applicable local authority having jurisdiction throughout New York State except New York City.

    • Inspections may be performed in person or remotely when the authority determines the remote inspection can be performed to the same level and quality and provides sufficient information; otherwise an in-person inspection is required.
    • Where applicable, inspections include the worksite before permit issuance, footing and foundation, concrete slab preparation, framing, structural/electrical/plumbing/mechanical/fire-protection systems, fire-resistant construction and penetrations, heating appliances/chimneys/flues/gas vents, Energy Code compliance elements, manufactured buildings or homes, and a final inspection.
    • Permit work must remain accessible and exposed until inspected and accepted; the permit holder must notify the authority when work is ready for inspection.
    • The state minimum standards do not require regular periodic inspections of owner-occupied one- and two-family dwellings or agricultural buildings used directly and solely for agricultural purposes, but this does not limit inspections invited by the owner or required where conditions threaten or present a public-health, safety, or welfare hazard.

Set by your town or city, not the county

In New York, zoning is adopted by each town or city, so Greene County has no county-wide answer on these. Find your town or city in the list of places on this page, or call its clerk or zoning administrator.

  • Lot coverage
  • Building height
  • Camping on your land
  • Tiny homes
  • Accessory dwellings
  • Short-term rentals

Each answer was extracted from an official source and independently re-checked against that source by a second reviewer. That is an evidence check, not legal advice. Rules change; confirm with the authority before you buy or build.
