In an effort to be carbon neutral by 2030, Dallas kicked off phase two of its Green Construction Ordinance—calling for all new commercial projects to meet the minimum number of points for LEED certification and comply with the city’s modified International Green Construction Code (IgCC). These mandates build off phase one, which launched in 2009 and gradually extended energy efficiency and water conservation benchmarks to more building types and sizes.

Under phase two, single-family and duplex homes must meet the minimum requirements set forth by Green Built Texas, LEED for Homes or ICC 700. Additionally, residential and commercial developers must attend a six-hour training course and pass an exam, and all project designs must be reviewed by a third party for compliance with LEED or the IgCC.
