An Act relative to the electrification of new and substantially remodeled or rehabilitated buildings in the city of Northampton

This bill authorizes the City of Northampton to mandate that new buildings and those undergoing major renovations use electricity or solar thermal energy for all power needs, including heating, cooling, and water heating. It defines major renovations as projects affecting over half of a building's floor area or involving significant changes to its heating and water systems. Under this law, the city could deny building permits for projects that do not comply with these electrification requirements, though it includes a process for requesting waivers if compliance is impractical. The legislation also lists specific exemptions, such as outdoor appliances, emergency power systems, and certain industrial facilities where fossil-free operation is deemed unfeasible.
