Denver energy and electrification legal challenges

Overview

Legal challenges have emerged regarding Denver’s energy and electrification ordinances. In August 2026, a federal judge upheld city restrictions that limit the use of gas appliances in new buildings, dismissing a lawsuit brought by trade groups such as the National Association of Home Builders and the Restaurant Law Center. The ruling affirmed the authority of local governments to regulate gas appliances for heating and water.

By September 2026, legal scrutiny expanded to the ‘Energize Denver’ ordinance and Colorado’s Regulation 28. A federal magistrate judge recommended that a lawsuit filed by commercial property groups, including the Colorado Apartment Association, proceed. The plaintiffs argue these regulations, which require large buildings to meet specific energy efficiency targets and reduce greenhouse gas emissions by 2032, effectively mandate electrification in a way that violates federal law.
