"New Jersey Impact Fee Act"; concerns municipal authority to impose impact fee for development of real property.

This bill, the "New Jersey Impact Fee Act," establishes rules for how New Jersey municipalities can charge developers a one-time fee to fund infrastructure (like roads, schools, and utilities) needed due to new construction. It requires fees to be based on local data (population, traffic, school needs) and used only for specific projects benefiting the development, not general costs or maintenance. Municipalities must publish annual reports online showing fee collection and spending, give 90 days' notice before new or higher fees, and prohibit changing fees after preliminary development approval. Developers may receive credits for contributing infrastructure instead of paying fees, and fees must be proportional to the development's impact.
