What the Eden code indicates by district
The table below shows how each district treats ADUs, alongside the lot and setback standards that govern a second unit. District boundaries and conditions vary, so treat this as a starting point and confirm the district that applies to your parcel.
| District | Min lot | Setbacks F / S / R | Max height | ADU |
|---|---|---|---|---|
| Agricultural Protection District | 4 ac | 50 / 35 / 35 ft | 35 ft | Occupancy restricted |
| Rural Residential District | 2 ac | 40 / 25 / 35 ft | 35 ft | Occupancy restricted |
| Multifamily Residential District | 2 ac | 50 / 35 / 35 ft | 35 ft | Occupancy restricted |

ADUs vs. short-term rentals in Eden
Short-term rentals allowed for Town of Eden. Eden EXPLICITLY PERMITS short-term rentals. Its Table IV-1 Table of Permitted Uses lists "Short-term rental/AirBnB" as a permitted (P) use in the PK, AP, RR and R2 districts, subject to § 225-15B, and not permitted in MFR or LI. This is an affirmative permission in the use table, not an absence of regulation — one of the few Erie towns to name STRs at all. Bed-and-breakfast is separately permitted in PK, AP, RR and MFR and by special permit in R2. New York State's 2025 STR registry (Ch. 99 of the Laws of 2025) still requires every host to register through the Erie County registry. Confirm the § 225-15B conditions with the building department at (716) 992-3408 before listing. 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.
