We read this municipality’s code, but parts of our finding still need confirming. Treat it as a starting point and confirm with the code office.
Dundee’s zoning schedule lists accessory apartments, including living quarters above garages or barns, among permitted accessory uses, but the schedule’s layout makes the districts unclear. Ask the village which districts allow them.
The code lists an accessory apartment as an allowed use, but in a limited form or with few written standards.
Whether any of this applies to your lot depends on your zoning district and your property.
The rules we found
| What the code says | Limited apartment allowed |
|---|---|
| Detached (backyard) unit | Schedule I names living quarters above garages or barns; which districts is unclear from the PDF layout |
| Inside or attached | Accessory apartments (including in the primary residence) appear among permitted accessory uses in Chapter 138 Schedule I; R-1 also allows conversions of single-family homes into 2- or 3-family dwellings with at least 500 sq ft per apartment |
| Size limit | Not applicable |
| Bedrooms | Not applicable |
| Owner must live on site | Not applicable |
| How approval works | Listed as a permitted accessory use; districts and permit steps unconfirmed |
| Other rules | Schedule I is amended through L.L. No. 3-2025 (2025-01-14); the item appears to sit in the C-1 row in the PDF layout, which may be a layout artifact. |

Before you spend money on drawings
- Confirm the Village of Dundee governs your lot: it should be the municipality on your property tax bill.
- Find your zoning district on the municipal zoning map; the rules above can differ by district.
- Call or write the code office with your address and what you’re picturing, and ask for the answer and the code section in writing.
- On septic or a well? Ask the NYS Department of Health’s Geneva District Office (315-789-3030) whether the system can serve an extra bedroom. On public sewer? Ask your sewer district.
