The Green Housing Coordination Temporary Amendment Act of 2025 aims to enhance energy efficiency in residential and mixed-use construction projects that receive assistance from the Housing Production Trust Fund. The bill introduces new net zero energy requirements, mandating that proposals for new construction be designed to achieve Enterprise Green Communities Certification Plus and be all-electric. Additionally, it establishes a reporting requirement for the Department of Buildings to provide updates on the development of universal net zero energy building code regulations, with the first report due by March 1, 2026, and subsequent reports every six months.

Furthermore, the bill amends the Green Building Act of 2006 by removing certain net zero energy compliance provisions and requiring the installation of rooftop renewable energy systems when a significant portion of the roof is replaced in residential projects. The amendments also clarify that the requirement for net zero energy compliance will not limit the applicability of other environmental standards. The act is set to take effect following approval by the Mayor and will expire after 225 days unless further action is taken.
