| District | Min lot | Setbacks F / S / R | Max height | ADU |
|---|---|---|---|---|
| SFR Single-Family Residential | 0.172 ac | 25 / 6 / 30 ft | 35 ft | No |

ADUs vs. short-term rentals in Hamburg
Short-term rentals restricted for Village of Hamburg. The Village of Hamburg legislates short-term rentals BY NAME in its use table and bans them from its largest residential district. Table 20.4 lists "Bed-and-breakfast or short-term rental" as an em dash — NOT PERMITTED — in SFR Single-Family Residential, and as SP (special permit) in TVR and LCR, subject to § 250-23.7. There is no as-of-right path in any residential district. New York State's 2025 STR registry (Ch. 99 of the Laws of 2025) applies on top of this. Confirm the § 250-23.7 conditions before listing. NOTE that building permits for the village are issued by the TOWN of Hamburg at 6100 South Park Avenue, not at Village Hall — (716) 649-4501 reaches village administration. Verified 2026-08-06. These are separate questions from whether you can build an ADU — a unit you're allowed to add isn't automatically one you're allowed to rent nightly, so check both.
