Maryland Building Performance Standards - Fossil Fuel Use, Energy Conservation, and Electric- and Solar-Ready Standards (Better Buildings Act of 2025)

HB 973, the Better Buildings Act of 2025, requires new buildings and major renovations (costing 50%+ of a structure's replacement value) in Maryland to meet all space heating, water heating, and laundry demands without fossil fuels. It mandates energy conservation standards and requires buildings to be "electric- and solar-ready," meaning they must have sufficient electrical capacity, wiring, and physical space for future installation of electric appliances and solar panels. The bill amends Maryland law to adopt these standards through the Department of Labor, aligning with but allowing stricter energy efficiency requirements than the International Energy Conservation Code. This directly affects developers, builders, and property owners constructing or significantly renovating buildings in Maryland.
