New York City - Local Law 92 and 94
Green Roofs & Solar Panels
Local Laws 92 and 94 mandate that any roof undergoing major construction be covered in either solar panels or a green roof system. Covered construction projects include new construction, vertical and horizontal extensions, and major modifications to the roof requiring a permit. Simple roof repairs and membrane replacements do not trigger the sustainable roof requirement. If triggered, the legislation requires that all available roof area be covered in either solar panels or a green roof system, excepting space required by New York City Fire Code and utilized by mechanical equipment.
