How Municipal Home Rule Works: What Cities Can Do Without Asking the State
A city council votes to raise the local minimum wage, ban a type of pesticide, or regulate short-term rentals, and within a year a state legislature passes a law wiping the ordinance out. Whether that override is even legal depends on a single, often-overlooked question: does the city have home rule, and if so, how much of it?

Unlike states, which hold sovereign power reserved to them under the Constitution, municipalities have no inherent constitutional authority of their own. A long-standing legal principle known as Dillon's Rule, named for an Iowa judge who articulated it in an 1868 opinion, holds that local governments possess only the powers a state legislature expressly grants them, powers necessarily implied by those grants, and powers essential to the city's stated purpose. Any doubt about whether a city has a given power is resolved against the city. Under a strict Dillon's Rule regime, a city cannot pass an ordinance on a subject unless it can point to specific state authorization for it.
Home Rule as the Alternative
Home rule flips that default. A state constitution or statute grants qualifying municipalities broad authority to legislate on local matters without needing case-by-case permission from the legislature, generally covering anything considered a matter of local rather than statewide concern. More than forty states offer some form of home rule, though the scope varies enormously: some states grant it automatically to cities above a population threshold, others require a city to adopt a home rule charter through a local vote, and a handful limit home rule to specific categories like taxation or zoning while leaving everything else under Dillon's Rule. A city can be constitutionally home rule for some purposes and legislatively dependent for others in the same state, which is part of why comparing "home rule states" to each other is trickier than it sounds.
Where the Real Fights Happen: Preemption
Home rule authority is never absolute, because state legislatures retain the power to preempt local ordinances even in home rule jurisdictions, and preemption fights have become one of the most active areas of state-local conflict. A city passes an ordinance restricting plastic bags, raising the local minimum wage above the state floor, or regulating landlord-tenant relationships, and the state legislature responds with a statute that expressly bars localities from legislating on that subject at all, sometimes retroactively voiding ordinances already in effect. Courts generally uphold these preemption statutes as long as the legislature had authority over the underlying subject matter to begin with, since home rule protects a city's process for legislating locally, not a guarantee that the state can never override the outcome.
Why Some Subjects Get Preempted More Than Others
Preemption clusters heavily around a few recurring categories: labor standards like minimum wage and paid leave, firearms regulation, short-term rental rules, and increasingly, local zoning decisions tied to housing supply. The pattern usually reflects which level of government a given political coalition currently controls rather than any principled theory about which issues are inherently local versus statewide — a state government controlled by one party will often preempt cities controlled by the other on exactly the issues where their policy preferences diverge most. This dynamic sits close to the tension explored in how power is divided between different levels of government, except playing out between states and their own cities rather than between states and Washington.
What Home Rule Does Not Cover
Even the broadest home rule grants stop well short of full local sovereignty. Cities cannot pass ordinances that conflict with the state or federal constitution, cannot regulate matters the state constitution reserves explicitly to the legislature, such as criminal law in most states, and generally cannot levy new categories of tax without specific state authorization even under a robust home rule charter. Financing constraints compound the limits: a home rule city with sweeping regulatory authority can still be boxed in by state-imposed debt ceilings and revenue caps, which is one reason how cities borrow and manage debt often matters as much to a city's practical independence as its home rule status on paper.
Reading a City's Actual Authority
Figuring out what a specific city can and cannot do requires checking three things in order: whether the state constitution or a home rule enabling statute grants the city home rule status at all, whether the city has taken the additional step of adopting a home rule charter where one is required, and whether the state has preempted the particular subject in question regardless of home rule status. Skipping any of the three steps leads to the common mistake of assuming a city's charter language settles the matter when a later state statute has quietly overridden it.
