Bill > S09742

This bill amends the multiple dwelling law to establish new standards for openable windows in newly developed residential units, including those converted from non-residential buildings. It states that if a unit meets the mechanical ventilation standards set by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), specifically ASHRAE Standard 62.1 or 62.2 (or their successors), these ventilation requirements will be considered satisfied, even if the existing law requires windows to be openable. This means that instead of relying solely on openable windows for ventilation, newly built or converted residential units can use advanced mechanical ventilation systems to ensure good indoor air quality. Importantly, the bill clarifies that this change does not prevent local governments from enforcing laws or ordinances that require openable windows for safety reasons, such as for emergency escape (egress) or fire safety.
