Chicago Green Roof Ordinance

The Chicago Green Roof Ordinance requires new commercial and residential buildings of a certain size to include green roofs or meet other sustainable design standards. Green roofs are covered with plants, which help reduce stormwater runoff, improve air quality, and lower urban heat. The goal is to make city buildings more environmentally friendly, enhance energy efficiency, and promote ecological benefits within Chicago’s urban landscape. This regulation encourages sustainable development practices to improve the city's overall urban environment and resilience to climate change.
