Home rule in the United States

Home rule in the United States relates to the authority of a constituent part of a U.S. state to exercise powers of governance (i.e., whether such powers must be specifically delegated to it by the state—typically by legislative action—or are generally implicitly allowed unless specifically denied by state-level action). Forty of the fifty states apply some form of the principle known as Dillon's Rule, which says that local governments may exercise only powers that the state specifically grants to them, to determine the bounds of a municipal government's legal authority.
