Clarkstown, N.Y., Code of Ordinances ch. 157 (eCode360 ed. 2026) § 157-32
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. Duets shall be securely fastened in place and appropriately firestopped.
Clarkstown, N.Y., Code of Ordinances ch. 157 § 157-32 establishes two mechanical ventilation requirements for one- and two-family dwellings. First, exhaust air from one dwelling unit must not be routed or recirculated into any other dwelling unit. Second, ducts must be firmly secured and properly firestopped to prevent the spread of fire through the ventilation system.
Plain English — not legal advice.
Under ch. 157 § 157-32, compliant operators ensure that each dwelling unit's exhaust air is fully isolated from adjacent units, with no shared recirculation pathways. Ductwork throughout the property is inspected to confirm it is securely fastened and that all required firestopping materials are installed at appropriate penetration points. Routine maintenance checks help confirm that these conditions remain in place over time.

Section 157-32 of Clarkstown's Code of Ordinances gives occupants of one- and two-family dwellings a basis to expect that exhaust air from a neighboring unit is not being circulated into their home, and that ductwork is safely secured and firestopped. If a tenant observes conditions that appear to violate these standards—such as odors or air flowing from an adjacent unit through shared ductwork—they may consider documenting the issue and contacting the local building or code enforcement office. Tenant-rights organizations can also help residents understand available options for raising such concerns.
