Establishes weatherization and energy efficiency pilot program to address open cockloft space between certain buildings; appropriates $30 million.

This bill establishes a pilot program in Union City, Trenton, and Camden to address open cockloft spaces between buildings through weatherization and energy efficiency improvements. It appropriates $30 million from American Rescue Plan Act funds ($10 million to each city) to cover the costs of installing fire-rated separations and other energy efficiency measures. Low- and moderate-income homeowners will receive these improvements at no cost, while other property owners may pay through a 10-year property tax special assessment. The program requires municipalities to conduct building inventories, implement safety measures, and report annually on the program's effectiveness to the legislature. The initiative aims to reduce energy costs, improve fire safety, and evaluate the feasibility of a broader statewide program.
