Bill > A08766

This bill amends the multiple dwelling law to establish new standards for window ventilation in residential units. Specifically, for newly developed residential units, including those converted from non-residential buildings, the requirement for openable windows can be satisfied by complying with the mechanical ventilation standards outlined in ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) Standard 62.1, which provides guidelines for acceptable indoor air quality. The bill mandates that these mechanical ventilation systems must provide adequate indoor air flow and air quality according to ASHRAE requirements. Additionally, the legislation prohibits local governments and municipalities from enacting or enforcing their own openable window requirements for residential units that meet these ASHRAE ventilation standards. The bill will take effect 90 days after becoming law, potentially providing more flexibility for residential developers in meeting ventilation requirements through mechanical systems rather than traditional openable windows.
