Illinois Firearm Laws: A Guide to Legal Ownership and Regulations

Understanding the complexities of Illinois gun laws is essential for responsible firearm ownership and ensuring compliance with state regulations. Whether you’re an Illinois resident or planning a visit, this guide will clarify the legal landscape around firearms in the state.

Firearm Owners Identification Card (FOID)

The Firearm Owners Identification Card (FOID) serves as the fundamental requirement for anyone seeking to own or possess firearms or ammunition within Illinois. To be eligible for a FOID card, you must meet the following criteria:

  • Be a resident of Illinois
  • Be at least 21 years of age (or 18 with parental consent)
  • Not have been convicted of a felony
  • Not have been a patient in a mental institution within the past five years
  • Not be subject to an active order of protection

The FOID application process is handled by the Illinois State Police (ISP) and involves a thorough background check ( Non-residents may possess firearms in Illinois under limited circumstances, such as if they hold valid firearm permits from their home state.

FOID cards can be denied or revoked for various reasons, including subsequent criminal convictions, mental health concerns, or violations of firearm laws. You can find more details in the Firearm Owners Identification Card Act (

The state also prohibits the possession of certain firearms and types of ammunition, such as assault weapons and armor-piercing bullets ([invalid URL removed]).

A critical component of purchasing a firearm in Illinois is the background check. This applies to all sales, even between private parties, and is conducted through the Illinois State Police. Firearms dealers are also required to maintain thorough records of every transaction for compliance with both state and federal laws.

Transporting Firearms in Illinois

As a general rule, Illinois law dictates that firearms transported in a vehicle must be unloaded and enclosed within a case. Transporting firearms across state lines is a complex issue and necessitates adherence to the laws of both Illinois and the destination state.

Concealed Carry License (CCL) holders have slightly more allowances when transporting loaded firearms in vehicles. However, specific restrictions still apply ([invalid URL removed]).

Concealed Carry Licensing

Illinois issues Concealed Carry Licenses (CCL) to eligible residents. To qualify, applicants must meet the following:

  • Be at least 21 years of age
  • Complete 16 hours of firearms training approved by the ISP
  • Pass background checks with no disqualifying factors

Concealed carry is prohibited in numerous designated locations in Illinois, including schools, hospitals, government buildings, and public transportation ( The application process for a CCL is managed by the Illinois State Police.

Illinois currently has limited reciprocity with other states regarding concealed carry licenses. It’s essential to be aware of the specific reciprocity agreements in place before traveling with a concealed firearm.

Prohibited Conduct

Illinois has specific laws outlining prohibited behaviors related to firearms:

  • Unlawful Use of Weapons (UUW): Encompasses various offenses, including possessing a firearm without a valid FOID or carrying a loaded firearm in prohibited areas.
  • Aggravated Assault and Aggravated Discharge: These are more serious offenses involving the use of a firearm to threaten or harm another individual.
  • Prohibited Locations: Firearm possession is strictly prohibited in certain locations like schools, courthouses, and some government buildings.

The Firearm Restraining Order Act

The Illinois Firearm Restraining Order Act ( provides a legal mechanism to temporarily restrict an individual’s access to firearms if they pose a significant risk of harm to themselves or others. Family members, household members, or law enforcement officers can petition a court for a Firearm Restraining Order (FRO).

The process typically involves presenting evidence to a judge demonstrating that the individual exhibits dangerous behavior or poses an immediate threat. If the judge approves the petition, the individual will be required to surrender any firearms in their possession and prohibited from acquiring new firearms.

Illinois’ Preemption Law

Illinois has a preemption law ([invalid URL removed]) which means that state-level firearm regulations generally supersede local ordinances. This law aims to prevent a patchwork of conflicting firearm regulations within the state.

However, local governments can still enact some firearm-related ordinances as long as they don’t directly conflict with state law. There have been legal challenges to the preemption law, making it a hotly debated topic within the state.

Staying Updated on Changing Firearm Laws

Firearm laws, both within Illinois and nationwide, are subject to change. It’s vital for gun owners and those interested in the issue to stay informed about legal updates. Here are essential sources to monitor for changes in Illinois firearm regulations:

  • Illinois State Police: The ISP website ([invalid URL removed]) provides the most up-to-date information on firearm laws, regulations, and relevant forms.
  • Illinois General Assembly: The legislature’s website ( is a reliable source for tracking new bills and changes to existing firearm laws.
