State Preemption of Local Firearm Regulations

The tension between state firearms preemption laws and local government desires to regulate firearms has intensified across the country. In Pennsylvania, Philadelphia and Pittsburgh have repeatedly attempted to enact local gun control measures, including restrictions on assault weapons, lost or stolen firearm reporting requirements, and limitations on firearms in parks and recreation centers. These efforts have been challenged under Pennsylvania's Uniform Firearms Act, which contains a preemption provision that appears to bar local regulation of firearms and ammunition.

Pennsylvania's preemption statute, 18 Pa.C.S. Section 6120, provides that no county, municipality, or township may regulate the lawful ownership, possession, transfer, or transportation of firearms, ammunition, or ammunition components when carried or transported for purposes not prohibited by the laws of the Commonwealth. The statute was amended in 2014 to add a private enforcement mechanism allowing individuals and organizations to sue municipalities that enact or enforce preempted ordinances and to recover damages, attorney's fees, and costs. This enforcement mechanism, while subsequently struck down by the Pennsylvania Supreme Court on standing grounds, reflects the legislature's strong intent to maintain uniform statewide firearms regulation.

The preemption analysis begins with the statute's plain text, which addresses four categories of firearms-related activity: ownership, possession, transfer, and transportation. The breadth of these categories is significant. "Ownership" encompasses the right to acquire and retain firearms. "Possession" covers both open and concealed carrying, as well as possession in the home, vehicle, or elsewhere. "Transfer" includes sales, gifts, loans, and other dispositions. "Transportation" covers the movement of firearms from place to place. Together, these categories cover virtually all aspects of the firearms regulatory space, leaving little room for supplementary local regulation.

The Pennsylvania Supreme Court has consistently interpreted the preemption statute broadly. In Ortiz v. Commonwealth (2011), the court held that a Philadelphia ordinance requiring the reporting of lost or stolen firearms was preempted because it regulated an aspect of firearm ownership and possession. The court rejected the city's argument that the ordinance merely regulated criminal conduct (failure to report) rather than firearms themselves, reasoning that the ordinance placed conditions on firearms ownership that the legislature had not imposed. Similarly, lower courts have struck down local ordinances banning assault weapons, restricting the number of firearms that may be purchased within a given period, and prohibiting firearms in certain public spaces.

The opinion identifies narrow areas where local authority may survive preemption. Zoning regulations governing the location of firearms dealers and shooting ranges have generally been upheld as exercises of the police power that regulate land use rather than firearms. Discharge ordinances, which prohibit the firing of firearms within certain areas, have also been permitted as safety regulations that do not restrict ownership, possession, transfer, or transportation. However, the line between permissible land use or safety regulations and impermissible firearms regulations is fact-specific and subject to judicial interpretation.

Pennsylvania's preemption statute broadly prohibits local regulation of firearms ownership, possession, transfer, and transportation. Municipalities may not enact ordinances that impose restrictions on these activities beyond those established by state law. Limited local authority is preserved for zoning regulations affecting firearms-related businesses and discharge ordinances governing the firing of weapons within municipal boundaries. Local officials should consult with their solicitors before enacting any ordinance that touches on firearms-related activity to ensure compliance with the preemption statute.

This opinion directly affects municipalities across Pennsylvania that have enacted or are considering local firearms regulations. Cities like Philadelphia and Pittsburgh must evaluate their existing ordinances for preemption compliance, and local officials face potential personal liability for enforcing preempted ordinances. Second Amendment advocacy organizations use preemption challenges as a primary litigation tool, and this opinion provides a roadmap for evaluating the vulnerability of specific local measures. Municipal attorneys should advise their clients that creative attempts to regulate firearms indirectly, such as through public health emergency declarations or nuisance theories, are likely to face preemption challenges and should be approached with caution.
