Healthy and Affordable Construction for Tomorrow Act.

This bill requires New Jersey to amend its construction code to prohibit burning high-emission fuels (like natural gas) in most new buildings. Starting 12 months after enactment, it bans such combustion in new buildings under seven stories, expanding to all new buildings after 36 months. Exemptions apply to emergency systems, emergency facilities, and commercial kitchens, but buildings using exemptions must still be designed as "all-electric ready" where feasible. The bill also mandates a joint report on utility rate changes and allows municipalities to enforce stricter rules than the state code.
