Sleepy Hollow, N.Y., Code of Ordinances ch. 245 (eCode360 ed. 2026) § 245-35
Air conditioning and mechanical ventilation in one- and two-family dwellings
Operative Text
A. Exhaust air from a dwelling unit shall not be circulated to another dwelling unit. B. Ducts shall be securely fastened in place and appropriately fire-stopped.
Section 245-35 of Sleepy Hollow's Code of Ordinances establishes two baseline requirements for air handling in one- and two-family dwellings: exhaust air from one dwelling unit must be fully expelled and may not be routed into any other unit, and all ductwork must be firmly secured and properly fire-stopped at required locations. These rules are designed to prevent cross-contamination of air between units and to limit the spread of fire through duct systems. The provision applies to the mechanical ventilation and air conditioning systems covered under Chapter 245.
Plain English — not legal advice.
Operators of one- and two-family dwellings subject to § 245-35 generally ensure that exhaust ductwork is designed and installed so that air discharged from one unit is vented entirely to the exterior rather than redirected into any adjacent or connected unit. Compliant property managers also verify that all ducts are mechanically fastened and that fire-stopping materials are correctly installed wherever ducts penetrate fire-rated assemblies. Routine inspections of ductwork connections and fire-stop integrity are a common part of maintaining compliance with Chapter 245.

Section 245-35 gives occupants of one- and two-family dwellings in Sleepy Hollow a basis to raise concerns if exhaust air from another unit appears to be entering their living space, or if ductwork appears unsecured or lacks proper fire-stopping. Tenants who observe potential violations may report them to the local building or code enforcement office in Sleepy Hollow, which has authority over Chapter 245 compliance. Tenant-rights organizations can also help residents understand what documentation to gather and what general options exist for addressing code concerns.
