Home Rule and State Preemption in Ohio

Whether an Ohio city can regulate guns, ban flavored vapes, or run traffic cameras is not really a local question — it is a contest between city halls and a Statehouse supermajority that keeps writing laws to override them. That contest runs on one clause of the state constitution, and two cases now before the Ohio Supreme Court will decide how much of it survives. It is the Democracy and Institutions (Ohio) question underneath a dozen fights on the 2026 slate: who governs closest to the people, and who gets to overrule them.

The 1912 grant

Ohio voters wrote home rule into the constitution in 1912, at Article XVIII, Section 3. It gives municipalities authority over local police, sanitary, and similar regulations and broad powers of local self-government — as long as local law does not conflict with the state's "general laws." That last phrase is the whole ballgame. Article XVIII never defines "self-government," so a century of litigation has turned on which local acts are protected self-rule and which are trumped by a valid general law.

The Canton Test

Since City of Canton v. State (2002), courts decide preemption with a four-part test. A state statute is a genuine "general law" — and can override a city — only if it:

1. is part of a statewide and comprehensive enactment;
2. applies uniformly to all parts of the state;
3. sets actual regulations on conduct, rather than merely limiting municipal power; and
4. prescribes a rule of conduct on citizens generally, not on city governments.

Fail any prong and the statute is an unconstitutional attempt to gut home rule. The test is the cities' main shield — which is why the state now wants it gone.

The state's preemption playbook

The Ohio General Assembly has preempted cities across issue after issue: firearms and large-capacity magazines, flavored tobacco and vapes, single-use plastic bags, ranked-choice voting, and traffic-camera enforcement. When a direct ban fails in court, the legislature switches tactics. After the Supreme Court struck down a state traffic-camera ban in 2017 as a home-rule violation, lawmakers in 2019 simply started deducting a city's camera revenue from its state funding — and in 2022 the court unanimously upheld that fiscal squeeze (the East Cleveland and Newburgh Heights case). Preemption by budget math, not by ban.

Doe v. Columbus — a procedural win for cities

Columbus passed ordinances (2022–2023) on large-capacity magazines and negligent firearm storage around minors. Anonymous plaintiffs sued under Ohio's firearm-preemption statute (R.C. 9.68), and a trial court froze the ordinances with a preliminary injunction. On April 1, 2026, in Doe v. Columbus (opinion by Justice Hawkins), the Supreme Court ruled 5-2 that enjoining a duly enacted city ordinance inflicts "irreparable harm" on a city's sovereign home-rule interests — so municipalities may immediately appeal such injunctions instead of waiting years for a final judgment. The ruling did not decide whether the ordinances survive; it just handed cities a faster way to fight.

The vaping case that could scrap the shield

The bigger threat came weeks later. House Bill 513 (2022) barred cities from banning flavored tobacco and vapes; DeWine vetoed the policy twice, and the legislature enacted it by veto override in 2024. Twenty-one cities sued, arguing the "ban on local bans" is not a general law because its only purpose is to disarm municipalities. An appellate court agreed. At oral argument on June 9, 2026, the state pressed a sweeping reading — that any law the General Assembly passes counts as a "general law" and that home rule "was never supposed to be this weapon that cities used to overturn state law." Local-government lawyers warn that reading would let the legislature block any municipal ordinance by declaring the subject one of "statewide importance."

Why it matters in 2026

• Cities are on defense. A 6-1 Republican Ohio Supreme Court holds the pen on how much local authority remains; the vaping case could narrow or effectively end the Canton Test.
• The subjects are the fights people feel. Guns, tobacco, wages, and elections are where preemption bites — local majorities pass a rule, the Ohio General Assembly erases it.
• The counter-move is direct democracy. When the Statehouse overrides both cities and the governor, the citizen ballot initiative is the remaining check — itself under pressure.
