Does Jamestown, NY have zoning?

Yes. The City of Jamestown divides the land inside city limits into zoning districts under its own zoning chapter¹. The districts are L-C, R-1, R-2, R-C, C-1, C-2, C-3, C-4, C-M, L-M and M, and the zoning map is kept at the office of the city clerk/treasurer⁵. The city's Department of Development also posts the zoning code and zoning map online².

Dimensions depend on the district. In the R-1 single-family residential district, a single-family dwelling needs a lot of at least 8,000 square feet and a width of at least 70 feet; other buildings need 10,000 square feet⁶. R-1 buildings may be no taller than 35 feet⁷.

Rules for RVs, tiny homes and accessory dwellings in the city are not confirmed. Ask the Department of Development before you plan to live in anything other than a conventional house.

What are the setbacks in Jamestown's R-1 district?

In the R-1 district, a building needs a front yard of at least 25 feet⁹. Side yards for dwellings and accessory structures are 10% of the lot width, but no less than 5 feet on each side⁹. The rear yard is 25% of the lot depth, but no less than 25 feet⁹. Other, non-dwelling buildings need 30 feet on each side yard⁹.

These figures are for R-1 only and are subject to exceptions in the city code⁹. The R-2, R-C and commercial districts use different numbers, so check the parcel's district on the zoning map before you buy⁶.

Do you need a building permit in Jamestown, and who issues it?

Yes, for work that must conform to the New York State Uniform Code. State rules require every local authority to require building permits for that work, with a short list of exemptions such as one-story detached sheds of 144 square feet or less⁴. In Jamestown, the city's Department of Development handles building permits, and applications must be submitted online².

The city's own code chapter on building construction and its local fee schedule were not confirmed, so ask the Department of Development about permit fees and which small projects are exempt. Afterward, a certificate of occupancy is required for work that needed a building permit¹⁰.

How do septic permits work in Jamestown?

Septic is a county matter, not a city planning matter. The Chautauqua County Health Department reviews private onsite wastewater systems, and when you apply for a building permit for a new building, added bedrooms or a change of use, the local code enforcement officer requires a letter from the department³¹¹.

Jamestown is served by public sewer in many areas, but we could not confirm which streets or parcels are connected. Under the county sanitary code, where an approved public sewer is accessible, an existing household sewage treatment system must be abandoned and connected to it⁸. Call the county Environmental Health Division and the Department of Development to find out whether a given lot has sewer access. Where onsite treatment is allowed, new construction needs a county permit, and the fee for a newly constructed system is $250¹².

What are the steps to build a home in Jamestown, NY?

1. Find the parcel's zoning district on the city's zoning map and read the dimensional rules for that district⁵.
2. Ask the county health department whether public sewer is available or an onsite system is allowed³.
3. Submit the building permit application online to the Department of Development².
4. Keep work exposed and accessible until inspected and accepted¹³.
5. Obtain a certificate of occupancy before moving in¹⁰.

If the parcel lies on a state highway, a driveway also needs a permit from the New York State Department of Transportation¹⁴.

What stays with Chautauqua County before you buy in Jamestown?

The county health department handles septic and sewer-connection questions for properties inside and outside the city³. For land outside Jamestown's city limits, the zoning and building permit rules come from the town or village in which the parcel sits, not from the city; see the Chautauqua County page for the county picture¹⁵.

Before buying, confirm the zoning district, sewer access, and whether the parcel is in a mapped flood hazard area, where a local floodplain development permit is required for private development¹⁶. Chautauqua County's effective property tax rate is 2.4%¹⁷.

Watch-outs

• The city's own building construction chapter, permit fees, and rules for RVs, tiny homes, accessory dwellings and minimum home size inside Jamestown were not confirmed; ask the Department of Development at (716) 483-7541².
• Jamestown's city zoning does not apply outside city limits, where the town or village sets zoning¹⁵.
• A public sewer connection can be required instead of a septic system where sewer is accessible⁸.
