Washington County, New York requires a county building permit for most projects, with an exception for a small detached shed not exceeding 144 square feet1. Zoning is set by each town and village, not the county, so the parcel's Town or Village Compliance Officer decides whether zoning or planning-board review applies before the county issues the building permit23. Septic permits for every address, town or village included, come from the county Department of Code Enforcement45.

Do you need a building permit in Washington County, New York?
Washington County requires building permits for most projects, with an exception for a small detached shed not exceeding 144 square feet1. New York requires permits for work that must conform to the Uniform Code or Energy Code, while allowing the local authority to exempt specified minor work; an exemption does not allow work that violates either code9. The current county fee schedule charges $0.30 per square foot for a new one- or two-family dwelling, with a $250 minimum, and the application fee is non-refundable6. County Code Enforcement performs onsite inspections during construction12. After completion, the local regulation compliance certificate must be returned before the county issues a Certificate of Occupancy or Certificate of Compliance13. For work whose permit status is unclear, describe the project to County Code Enforcement before ordering materials.
Who issues building permits in Washington County, and how do you reach them?
The Washington County Department of Code Enforcement reviews plans, issues building permits, inspects construction, and issues certificates after applicable code requirements are met14. Its office is at 1153 Burgoyne Ave, Fort Edward, NY 12828, and its phone number is (518) 746-215014. The application does not go straight from the owner to final county review: first complete the county application, then take it to the parcel's Town or Village Compliance Officer for a decision on zoning or planning-board review and the required local signature3. After local sign-off, submit the package to County Code Enforcement3. A completed project also needs local sign-off before the county can issue its Certificate of Occupancy or Certificate of Compliance13.
Does Washington County, New York have zoning?
Zoning in Washington County is set by each town and village, not by the county: New York is a home-rule state, and land-use decisions are made by each municipality2. New York has not delegated zoning power to counties15. Setbacks, minimum lot size, site-plan review and similar parcel rules therefore vary by town or village8. The county building-permit process still sends every applicant to the local Town or Village Compliance Officer, who decides whether zoning or planning-board review is required3. What stays with the county is the building permit itself and the septic permit, both issued by County Code Enforcement14. The County Planning Agency does not conduct subdivision review under GML §239-N, but municipal subdivision laws can still apply16. Identify the exact municipality and get its written requirements before designing a house, driveway, RV pad, or lot split.
Who issues septic permits in Washington County, New York?
A Sewage Disposal System permit from Washington County is required before septic construction begins, and the county Department of Code Enforcement administers the Washington County Sanitary Code45. The current county schedule lists a $100 non-refundable application fee for a sewage-disposal system6. The Department of Code Enforcement administers onsite systems under the Washington County Sanitary Code and reviews plans for work governed by that code517. If a project adds wastewater design flow, the septic application must be approved before the building permit can issue4. A system discharging less than 1,000 gallons per day to groundwater may avoid a state SPDES permit, but that exception does not remove local approval requirements18. Only 1.7% of county soils rate without severe limitations for a conventional drain field, so a parcel-specific site evaluation matters early11. An inspection report is required with the county septic replacement-grant application, but that form does not establish a general inspection-report requirement for every system19.
Can you live in an RV or tiny home on land in Washington County, New York?
We could not confirm one Washington County rule for long-term RV living, temporary camping, tiny-home occupancy, minimum dwelling size, or setbacks. Ask the parcel's Town or Village Compliance Officer because municipalities make land-use decisions and local requirements vary8. A tiny home used as a dwelling does not escape applicable New York building rules merely because it is small: work governed by the Uniform Code or Energy Code requires a building permit unless the enforcing authority has adopted an allowed exemption9. Occupancy of work covered by a building permit requires a Certificate of Occupancy or Certificate of Compliance20. Before buying, ask the local compliance office specifically about the proposed structure, foundation, utilities, duration of RV use, and occupancy during construction.
Building a home in Washington County, New York: the steps, in order
- Identify the parcel's town or village and ask its Compliance Officer about zoning, planning-board review, floodplain rules, and local site requirements821.
- Confirm driveway jurisdiction; a driveway permit may come from NYSDOT, Washington County DPW, or the town or village, and a residence on a state highway needs a NYSDOT permit to build or modify a driveway2223.
- Complete the Washington County building-permit application, obtain municipal sign-off, and budget from the current county fee schedule36.
- Submit the sewage-disposal application early when onsite septic is needed; septic approval may be required before the building permit issues4.
- Submit the signed package to County Code Enforcement and keep permitted work accessible for required construction inspections324.
- After construction, return the final local compliance certificate and obtain the county Certificate of Occupancy or Certificate of Compliance before occupancy13.
What should you check before buying land in Washington County, New York?
Confirm the municipality first, because zoning and other land-use decisions vary across Washington County8. Check whether a local flood-hazard permit is required and whether a driveway permit belongs to NYSDOT, Washington County DPW, or the town or village2122. Investigate septic feasibility before treating a parcel as buildable: only 1.7% of county soils rate without severe limitations for a conventional drain field11. We could not confirm a Washington County well-permit rule, so ask County Code Enforcement what water-source documentation and outside approvals apply. For carrying cost, the county's effective property-tax rate is about 2.1%, with a median annual bill near $3,8522526. The nearest city of 100,000 or more people is about 56 miles from the county's center27.
Watch-outs
- A Washington County building-permit application needs local zoning review and sign-off from the town or village before it goes to County Code Enforcement3.
- A required driveway permit may come from NYSDOT, Washington County DPW, or the local town or village, depending on the road22.
- New York does not license home-improvement contractors statewide, but that does not create an exemption from local permits, inspections, or trade licenses10.
