ADUs vs. short-term rentals in Germantown
Short-term-rental status not confirmed for Town of Germantown. A proposed STR local law (Local Law C of 2023) went to a public hearing on 19 October 2023 and a revised draft circulated in February 2024; adoption could not be confirmed. The Zoning and Subdivision Law as published contains no short-term-rental provision — it permits a BED AND BREAKFAST, an owner-occupied single dwelling unit accommodating transient guests, by special permit in four districts and by right in three — so the published document predates the draft and cannot settle it. Ask the Town whether Local Law C was adopted. New York State's 2025 short-term rental registry (Ch. 99 of the Laws of 2025) separately requires every host statewide to register the unit regardless of local law. Confirm with Town of Germantown at (518) 537-6687 before listing. 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.
