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 lies12. Zoning approval is also municipality-specific, while the NYSDOH Oneonta District Office handles environmental health services, including septic matters, throughout the county34.

Do you need a building permit in Greene County, New York?
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 it9. 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 codes10. 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 occupancy267. Greene County Planning can help identify municipal zoning resources, but it does not replace the local building or zoning office11. 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 minimum12. 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 referral13.
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 codes314. 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 requirements15116. 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 service17. 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 rear1819. 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 construction5. The NYSDOH Oneonta District Office conducts environmental health services for all Greene County addresses because Greene County Public Health is a partial-service department413. 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 condition20. 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 period21.
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. Zoning and allowed uses vary by town or village, while the state building code and septic approval remain separate requirements395. 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 campground22. 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 use17. 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 municipal23.
- Ask the local zoning or code office to confirm the district, allowed residential use, setbacks, minimum lot size, application documents and fees11.
- Obtain health-authority approval for the septic-system plans before construction; the NYSDOH Oneonta District Office handles Greene County environmental health services54.
- Apply to the municipal code enforcement officer for the building permit2.
- Call for required building inspections and leave covered work accessible until it is inspected and accepted6.
- Obtain the certificate of occupancy or compliance before occupying the completed permitted work7. A county homeowner electrical permit is narrow and does not exempt a new house from this process8.
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 description214. Test septic feasibility early because only about 0.9% of county soils are rated without severe limits for a conventional drain field20. 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 officer16. 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 rule23. For a private well, use a registered contractor who will notify the state before drilling and file the completion report afterward24.
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 matters234.
- 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 district122519.

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
