Federal and state preemption laws threaten local firearm regulations and can prevent local officials from protecting their communities against gun violence.

When it comes to gun violence, local laws serve the important purpose of addressing the unique issues and dangers facing each different community. When a higher level of government takes regulatory power from a lower level, it can create a dangerous gap between the people passing laws and those living with them every day—and in the case of gun regulation, that gap can have deadly consequences.


“Preemption” occurs when a higher level of government removes regulatory power from a lower level of government. With very narrow exceptions, Congress has not expressly preempted state or local laws regulating firearms and ammunition. In fact, for most of the nation’s history, local governments generally had the authority to enact their own firearm regulations in the interest of protecting public safety. However, in recent years, at the urging of the gun lobby, most states have explicitly removed authority from local governments to regulate guns and ammunition, thereby creating a dangerous exception to the traditional rule of local authority.

Broad state preemption statutes threaten public safety because they:

  • Ignore important local variations that make varying approaches to preventing gun violence appropriate in different areas, like the differences between urban and rural communities.
  • Hinder enforcement of gun laws, because the Bureau of Alcohol, Tobacco, Firearms & Explosives and state law enforcement agencies generally lack the resources or authority to properly oversee all the firearms businesses in their jurisdictions.
  • Thwart local innovation in gun violence prevention strategies which can lay the groundwork for state-level change. For example, California allows local regulation of guns, and several of the state’s important firearm policies, like requiring a locking device be included with every firearm purchase, began as local regulations before being adopted state-wide.

Recent examples demonstrate how preemption laws threaten public safety and tie the hands of local officials who want to protect residents from gun violence.

  • Officials in Richmond, Virginia banned bats, shields, knives, and poles from a white supremacist protest organized shortly after the deadly violence in Charlottesville. Because of the state’s preemption laws, however, local officials couldn’t prohibit guns at the rally.1
  • Okaloosa County, Florida officials passed an ordinance banning firearms, trampolines, and bounce houses in beaches, parks, and recreation areas. Because of the state’s firearm preemption law, local officials were forced to lift the ban on gun carrying in those public places, though the ban on bounce houses and trampolines was allowed to go into effect.2

Some states have enacted extreme preemption laws that subject local officials to personal liability and removal from office for taking action to address gun violence. This approach, which punishes legislators for their official acts, is likely unconstitutional. 3

The principle that legislators are absolutely immune from liability for their legislative activities has long been recognized in Anglo–American law. This privilege “has taproots in the Parliamentary struggles of the Sixteenth and Seventeenth Centuries” and was “taken as a matter of course by those who severed the Colonies from the Crown and founded our Nation.” Tenney v. Brandhove, 341 U.S. 367, 372 (1951).

Under the U.S. Constitution, legislative immunity is protected by the Speech or Debate Clause of Article I, Section 6. Bogan, 523 U.S. at 46. State courts have also recognized that legislative immunity provisions enshrined in state constitutions also protect this bedrock principle. See Florida House of Representatives v. Expedia, Inc., 85 So. 3d 517, 523 (Fla. Dist. Ct. App. 2012). “It is clear . . . that the privileges and immunities protecting all public officials, including members of the legislature, arise from the common law. The significance of this point is simply this: if legislative privileges and immunities existed under the common law, they continue to exist, apart from specific constitutional provisions like the Speech or Debate Clause, to the extent that a state continues to recognize the common law.”)) and may deter or intimidate qualified individuals from running for office or taking valid local legislative actions for fear of personal liability.

  • Under Florida’s preemption law, for example, local officials who enact any firearm rules or regulations are subject to fines up to $5,000.4 The statute as-enacted provided that local officials could be removed from office for legislative actions in violation of the preemption statute, but this provision was struck down.5
  • In Kentucky, if a local official violates “the spirit” of the state’s firearm preemption law, she is subject to criminal penalties, and individuals and organizations can seek damages and litigation fees from local officials who attempt to address gun violence.

Summary of Federal Law

Under the Supremacy Clause of Article VI of the US Constitution, a federal law is binding on all state and local governments so long as Congress duly enacted the law pursuant to one of its limited powers. Federal preemption of state law is uncommon in the area of firearms regulation, however.

Congress may make its intention to preempt an area of state law clear by expressly stating its intent in the language of a statute. Absent such a statement, when considering a challenge to a state or local law based on the claim that regulation of the subject has been preempted by Congress, courts presume that the federal government does not intend to preempt state and local authority.6

Congress has not expressly preempted the broad field of firearms or ammunition regulation. Furthermore, courts have held that congressional regulation of firearms does not create a scheme so pervasive that it leaves no room for state and local law.7Thus, absent a specific, irreconcilable conflict between a challenged state or local firearms or ammunition law and a federal enactment, there is no federal preemption of that state or local law.

Summary of State Law

States differ considerably in how and to what extent they preempt the regulation of firearms and ammunition. Specific questions about whether a particular type of local regulation may be preempted in any given state involve complex inquiry and analysis of existing case law. Giffords Law Center is available to consult with officials and advocates on specific questions relating to their jurisdiction.

Generally, preemption occurs in two ways: through express preemption and implied preemption. Express preemption occurs when a state provides explicitly, in the language of a statute or constitutional provision, that it intends to remove a lower government’s regulatory authority. For example, the South Dakota legislature expressly preempts county legislative authority to regulate most aspects of firearms and ammunition with the following statutory language:

“No county may pass an ordinance that restricts or prohibits, or imposes any tax, licensure requirement, or licensure fee on the possession, storage, transportation, purchase, sale, transfer, ownership, manufacture, or repair of firearms or ammunition or their components. Any ordinance prohibited by this section is null and void.”8

Absent an express statement, courts may infer an intent to take over a field of regulation, even though there is no express legislative statement to that effect. This is referred to as implied preemption. In general, courts may find that a local law is preempted if it conflicts directly with state law by requiring what the state law prohibits, or prohibiting what the state law requires. In addition, when a comprehensive scheme of state regulation exists on a particular subject matter, many state courts find that the state legislature thereby indicated an intent to assert exclusive authority over that subject matter.9

The existence and degree of express state preemption of local firearms and ammunition regulation varies from state to state, as do the tests courts use to determine whether implied preemption exists.


We’re in this together. To build a safer America—one where children and parents in every neighborhood can learn, play, work, and worship without fear of gun violence—we need you standing beside us in this fight.

The discussion below groups the states into three categories based on the extent of express preemption of local authority to regulate firearms and ammunition and then comments on issues of implied preemption where appropriate:

States with No Firearm-Related Preemption Statutes

In Connecticut, Hawaii, Massachusetts, New Jersey, and New York, there are no state laws expressly preempting local authority to regulate firearms or ammunition. In Connecticut, Massachusetts, New Jersey, and New York, courts have interpreted the degree to which local governments can regulate firearms in the absence of express preemption. Although each local law must be evaluated on a case-by-case basis, some general preemption principles for each state are outlined below.10


In Connecticut, a local government is preempted from regulating a subject matter when the state has demonstrated an intent to occupy the entire field of regulation in that area or when the ordinance at issue irreconcilably conflicts with a state law.11 Connecticut courts have not found that the legislature has demonstrated an intent to occupy the field of firearms and ammunition regulation.12 Thus, absent a direct conflict with state law, broad local firearms and ammunition regulation appears to be possible.


Hawaii courts, like those in Connecticut, will generally find that a local ordinance is preempted when it addresses an area the state has intended to regulate exclusively and uniformly, and/or when it conflicts with state law.13 Giffords Law Center is not aware of any published case interpreting the extent of local authority to regulate firearms and ammunition in Hawaii. In the absence of any contrary authority, it appears that local governments have broad authority to regulate firearms and ammunition unless there is a conflict with state law.


When presented with a preemption challenge, Massachusetts’ courts consider whether an inference can be made that the legislature intended to preempt the subject matter addressed by the ordinance at issue. Courts may infer such intent when a local law frustrates the purpose of a state law either directly or due to a comprehensive scheme enacted by the legislature.14 Courts also may find that local law is preempted if it conflicts with state law.15 Thus, so long as there is no conflict with state law, it appears that local governments may regulate broadly in the area of firearms and ammunition. Furthermore, even when a state law and a local law address the same subject area, a stricter local law may be permissible. For example, the Supreme Judicial Court of Massachusetts upheld a local firearm discharge ban, finding that it did not frustrate the state’s hunting license law even though it was more stringent than state law concerning the safe use of firearms.16

New Jersey

New Jersey municipalities enjoy express authority to regulate and prohibit the sale and use of firearms.17 However, local governments may not enact regulation that conflicts with any policy of the state.18 In the absence of a conflict, local governments appear to have broad authority to regulate firearms and ammunition, and at least in one area of firearms regulation, are authorized to enact local laws that are stricter than state laws addressing the same subject.19 In a case upholding a local firearms discharge ordinance, the New Jersey Supreme Court concluded that a state law regulating hunting was not intended to preempt a stricter local law.20

New York

New York courts use a test to evaluate preemption challenges similar to many of those described above—a local law may not conflict with a state law or regulate in an area that is occupied by the state.21 New York courts have not found that the state has preempted the broad field of firearms and ammunition regulation. Courts have upheld several local firearms laws against preemption challenges and have found that the state has intended to occupy only limited areas of firearms regulation, such as the regulation of air guns.22 Thus, local governments in New York appear to have broad authority to regulate firearms and ammunition absent conflict with state law.

States with Limited Firearm-Related Preemption Statutes

California and Colorado allow local governments to retain substantial authority to regulate firearms and ammunition, but the state legislature has expressly removed this authority in certain areas.


California expressly preempts local governments from regulating in the areas of registration or licensing of firearms; manufacture, sale or possession of imitation firearms; and licensing or permitting with respect to the purchase, ownership, possession or carrying of a concealable firearm in the home or place of business.23 In other areas, courts have found that local governments have a great deal of authority to regulate firearms and ammunition in their communities.24 For example, courts have rejected preemption challenges to many local firearms and ammunition laws, including ordinances regulating the location and operation of firearms dealers, and the sale and possession of firearms and ammunition on county-owned property.25


In 2021, the Colorado General Assembly became the first state in the nation to broadly repeal the majority of its firearms preemption statute and allow local governments, special districts, and the governing boards of institutions of higher education to regulate firearms.26 Limited areas of firearms preemption remain. For more information on firearms preemption in Colorado, visit our preemption in Colorado page here.

States With broad Firearm-Related preemption statutes

In the remaining 43 states, local governments possess limited authority to regulate firearms and ammunition. The preemption statutes in these states vary, but each one expressly preempts all, or substantially all, aspects of local firearms and/or ammunition regulation. In many of these states, there are statutory exceptions that may permit some local firearms and/or ammunition regulation. Giffords Law Center is available to assist public officials and activists in evaluating potential local strategies to prevent gun violence.

States that have enacted extreme preemption statutes

States with extreme preemption laws allow courts to impose fines, civil liability, or both, on legislators who are found to violate the state’s preemption statute. In the most extreme example, Kentucky imposes a criminal penalty on a legislator who runs afoul of the state’s prohibitions. Some states also allow membership organizations, such as the NRA, to sue the locality or local legislators. The different approaches taken by states with extreme preemption laws are discussed below.

States that impose fines against local legislators personally for violating the preemption statute

  • Arizona, up to $50,00027
  • Florida, up to $5,00028

States that make local officials personally liable for damages and/or attorney’s fees for violating the preemption statute

  • Florida29
  • Iowa (limited)30
  • Kentucky31
  • Minnesota (limited)32
  • Mississippi33
  • Oklahoma34
  • Tennessee35

States that expressly authorize the removal of local officials from office for violating the preemption statute

States that make local legislators criminally liable for violating the state’s preemption statute

  • Kentucky37

Despite this statutory and case law supporting municipal authority to regulate firearms, a superior court case invalidated a local firearms ordinance limiting handgun sales and purchases to one per person per 30-day period, on preemption grounds. In 2008, a New Jersey appeals court affirmed the ruling, on the grounds that state law preempted the local law. However, that appellate court opinion and judgment were vacated, and the appeal dismissed as moot, by the Supreme Court of New Jersey because the state legislature adopted an identical 30-day handgun sales limitation while the Supreme Court appeal was pending. Ass’n of New Jersey Rifle & Pistol Clubs, Inc. v.

  24. See, e.g., Suter v. City of Lafayette, 67 Cal. Rptr. 2d 420, 425 (Cal. Ct. App. 1997) (“That state law tends to concentrate on specific areas, leaving unregulated other substantial areas relating to the control of firearms, indicates an intent to permit local governments to tailor firearms legislation to the particular needs of their communities.” Note however, that while the Suter court upheld an ordinance regulating the location and operation of firearms dealers, it struck down the portion of the ordinance regulating firearm storage).[]
  25. Cal. Rifle and Pistol Ass’n, Inc. v. City of W. Hollywood, 78 Cal. Rptr. 2d 591 (Cal. Ct. App. 1998) (upholding ordinance banning junk guns); Suter, 67 Cal.

King, 44 P.3d 133 (Cal. 2002) (upholding ordinance banning possession of firearms and ammunition on county-owned property). In contrast, in Doe v. City and County of San Francisco, 186 Cal. Rptr. 380 (Cal. Ct. App. 1982), the court held that California Gov’t Code § 53071 and Cal. Penal Code § 12026 (subsequently renumbered as § 25605) preempted a San Francisco ordinance banning handgun possession. Because the ordinance contained an exception for concealed weapons licensees, the court found the measure had the effect of creating a new class of persons who would be required to obtain a license in order to possess a handgun in their home or place of business. Similarly, in Fiscal v. City and County of San Francisco, 158 Cal. App. 4th 895 (Cal. Ct. App. 2008), the same court that decided the Doe case, held that a municipal ordinance prohibiting the sale, distribution, transfer, and manufacture of all firearms and ammunition in San Francisco and banning possession of handguns by San Francisco residents was preempted by state law. The California Supreme Court declined to review the case.[]
