Watervliet, N.Y., Code of Ordinances ch. 175 § 175-47
Air-conditioning and mechanical ventilation in multiple dwellings
Operative Text
A. Refrigerants. (1) Refrigerants that are highly flammable shall not be used in multiple dwellings. (2) Direct systems using refrigerants that are flammable or toxic shall not be used for air-conditioning purposes. B. Ventilating systems. (1) Ventilating systems shall be installed and maintained so that the rapid spread of heat, flame or smoke through the system will be prevented and so that under conditions of use the temperature of any combustible material adjacent thereto or in contact therewith will not exceed a safe temperature. (2) Stairways, passageways, exits, shafts, hoistways or attics shall not be used as plenum chambers. (3) Ducts shall be securely fastened in place and appropriately firestopped. (4) Ducts and other air-handling equipment shall be of noncombustible material. (5) Filters shall be installed and maintained so as not to constitute a fire or smoke hazard. (6) Ducts passing through or located within combustible construction shall be separated from such construction by a clearance of at least /2 inch or by a noncombustible insulating material at least 1/4 inch thick. (7) Air required for ventilation shall be taken from the exterior or shall be quality-controlled. (8) Exhaust air from a dwelling unit or a space whose contents may emit odors, fumes or vapors shall not be circulated to other occupied spaces within the building. C. Air intake and exhaust openings. (1) Air intake and exhaust openings shall be installed, located, and maintained so as not to constitute a hazard or nuisance and so as to prevent the possibility of fire, smoke, fumes or foreign matter being drawn into the system. (2) Ventilating systems shall be provided with adequate openings for incoming and outgoing air to obtain the required circulation. Intake openings shall provide air from an uncontaminated source. (3) Where openings for mechanical exhaust are located in spaces that also contain fuel-burning equipment, there shall be provided fixed intake openings from the exterior to supply sufficient air so that the fuel-burning equipment is not adversely affected. (4) Exhaust openings shall be located so that the exhaust air will not create a nuisance. D. Ventilation requirements. (1) Enclosures or spaces where heat, gases, vapors or odors may accumulate and become a potential source of hazard or nuisance shall be provided with an adequate means of ventilation to remove such excess. (2) Public spaces shall be provided with a means for obtaining air supply for the maximum number of persons for which such spaces are designed. E. Safety controls. (1) Manually operated controls shall be provided to stop the operation of all central fan equipment. Such controls shall be conspicuously identified and in readily accessible locations outside the fan room. (2) Every system using recirculated air and serving an assembly space or more than one fire area or more than one story of a building, shall be provided with controls arranged so that under abnormal rise in temperature of the air in the system and fans causing normal circulation shall stop and require manual restart. (3) Every system for ventilating an assembly space shall be provided with an emergency switch conveniently located and with a durable sign giving instructions for shutting down the system in case of fire.
Section 175-47 of Watervliet's Code of Ordinances establishes detailed safety standards for air-conditioning and mechanical ventilation systems in multiple dwellings. The provision prohibits the use of highly flammable or toxic refrigerants, requires that ductwork, filters, and air-handling equipment be made of noncombustible materials and properly firestopped, and mandates that exhaust air from odor- or fume-producing spaces not be recirculated to other occupied areas. It also requires that ventilation systems include safety controls—such as manual shutoffs and emergency switches—capable of halting fan operation during abnormal temperature rises or fire conditions.
Plain English — not legal advice.
Operators of multiple dwellings subject to Watervliet Code ch. 175 § 175-47 generally ensure that all HVAC and ventilation equipment is selected, installed, and maintained in accordance with the provision's fire and air-quality requirements. Compliant operators use only approved refrigerants, verify that ducts are constructed of noncombustible materials and properly secured and firestopped, and confirm that air intakes draw from uncontaminated exterior sources. They also maintain accessible manual shutoff controls for central fan systems and, where assembly spaces or multi-story systems are involved, ensure automatic temperature-triggered shutdowns and clearly marked emergency switches are functional.

Residents of multiple dwellings in Watervliet are protected under § 175-47 from fire hazards and air-quality risks associated with improperly installed or maintained ventilation systems, including protections against recirculation of fumes or odors from other units into their living spaces. If a tenant observes conditions that appear to violate these standards—such as malfunctioning exhaust systems, missing or damaged ductwork, or absent emergency controls—they may document the issue and report it to the appropriate local code enforcement or housing authority. Tenant-rights organizations can help residents understand what remedies or complaint processes may be available under this provision.
