Building permits are required for work that must conform to the Uniform Code or Energy Code, although the local enforcement program may allow certain exceptions5. A qualifying one-story detached tool or storage shed of no more than 144 square feet is among the categories a local program may exempt, but exempt work must still comply with the codes10. Before the local Code Enforcement Officer issues a permit for a new building, added bedrooms or a change in use, the Chautauqua County Health Department must verify that the onsite wastewater system is appropriate2,6. Permitted construction is subject to inspections, and the work must remain accessible and exposed until the municipality accepts it1.

Cities, towns and villages typically administer building permits and code enforcement in Chautauqua County, while responsibility can pass to the county or the New York Department of State if the relevant local governments opt out1. Start with the county's directory of municipal officials to identify the correct town or village office for the parcel11. The county switchboard is 716-753-4000 at Chautauqua County Offices, 3 N Erie Street, Mayville, NY 1475711. The building-permit application must give the code official enough information to evaluate compliance, including the work location and scope, tax-map number, street address, occupancy classification, applicable special-inspection statement and construction documents5. For a new building, added bedrooms or a change in use, contact the Chautauqua County Health Department at 716-753-4312 for septic review6. A certificate of occupancy or compliance is required before permitted work may be occupied1.
Does Chautauqua County have zoning?
Zoning in Chautauqua County varies by municipality rather than following one uniform set of parcel rules.
Zoning in Chautauqua County varies by municipality rather than following one uniform set of parcel rules4. All municipalities in the county have zoning laws or ordinances except the Towns of Ellington, French Creek and Sherman4. For land in a municipality with zoning, ask that municipality about the parcel's district, allowed uses, setbacks, minimum lot or dwelling size, accessory dwellings and permit requirements because those details were not confirmed countywide4. For land in Ellington, French Creek or Sherman, the absence of a zoning law or ordinance does not remove the statewide building-code permit process or the county septic process3,4,10.
How do septic permits work in Chautauqua County?
The Chautauqua County Health Department handles private onsite wastewater treatment systems across the county and decides whether an existing system can serve a new building, added bedrooms or a change in use.
The Chautauqua County Health Department handles private onsite wastewater treatment systems across the county and decides whether an existing system can serve a new building, added bedrooms or a change in use2. A new or corrected system requires an application, proposed layout, percolation-test results, soil information and a fee; construction begins only after county approval and permit issuance or verbal approval3. The published fee is $250 for a new system or a correction or replacement, $100 for a septic-tank or distribution-box-only replacement, and $50 for a permit extension; credit-card payments add 2.75%3. The contractor must request final inspection with at least 48 hours' notice, and the system cannot be used until the county approves it3. Only 1.1% of county soils are rated without severe limits for a conventional drain field, so establish site feasibility early8. Reach Environmental Health at 716-753-43126.
Can you live in an RV or tiny home on your land in Chautauqua County?
We could not confirm a countywide rule allowing long-term RV occupancy or tiny-home occupancy in Chautauqua County.
We could not confirm a countywide rule allowing long-term RV occupancy or tiny-home occupancy in Chautauqua County. Municipal zoning varies, and all municipalities except the Towns of Ellington, French Creek and Sherman have zoning laws or ordinances4. Ask the municipality with jurisdiction whether an RV, tiny home or accessory dwelling is allowed on the parcel and what use, setback or size rules apply; use the county directory to find that office11. A tiny home that involves work covered by the Uniform Code or Energy Code still requires the applicable local building permit, inspections and an occupancy certificate1,10. Any private onsite wastewater construction also requires county approval and permitting3.

Zoning: identify the municipality and obtain its parcel-specific rules; only Ellington, French Creek and Sherman lack zoning laws or ordinances4. Septic: only 1.1% of county soils are rated without severe limits for a conventional drain field, and a private system needs county review before construction3,8. Existing system: ask the Health Department whether its records show that the system is appropriate for the planned building, bedroom count or use2. Public sewer: where an approved public sewerage system is accessible to a property in the Chautauqua County Health District, the county health code requires a household septic system to be abandoned, with connection due within 90 days of a Public Health Director order12. Access, wells and floodplain: we could not confirm countywide permit rules, so ask the municipality with jurisdiction before closing. Taxes: the effective property-tax rate is about 2.4%, and the median annual bill is about $2,8468. Terrain: about 91.6% of county land has a slope of 15% or less, but parcel-level soils and drainage still need evaluation8.
Watch-outs
- New York does not issue a statewide home-improvement-contractor license, but that does not exempt an owner-builder from local permits, inspections or licenses for particular trades; ask the local Code Enforcement Officer what an owner may perform7.
- A Right To Connect letter from the Chautauqua County Health Department is a prerequisite most buyers overlook: your town will not issue a building permit for new construction, added bedrooms, or a change of use without it, so start that review before you finalize house plans6.
- RV and tiny-home occupancy rules were not confirmed countywide; ask the municipality with jurisdiction, noting that Ellington, French Creek and Sherman are the only towns identified as lacking zoning laws or ordinances4.
