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 residential buildings. It appropriates $30 million to provide weatherization and fire safety improvements - specifically installing fire-rated separations and optional energy efficiency upgrades like insulation - free of charge to low- and moderate-income homeowners. Property owners not qualifying for free services may pay for the work through a 10-year property tax special assessment. The program directly affects residential building owners in these three cities, aiming to reduce energy costs, improve fire safety, and evaluate the effectiveness of weatherization measures in urban areas.
