What Are Illinois Gun Laws?

Illinois gun laws regulate who can possess firearms, how they must be stored and transported, and where they can be carried. These laws aim to balance the rights of gun owners with the state’s responsibility to protect public safety. Illinois residents must adhere to strict requirements, including obtaining a firearm owner’s identification card (FOID) and, in some cases, a concealed carry license.

One of the most well-known elements of Illinois gun laws is the assault weapons ban, which limits the possession and sale of certain types of firearms classified as assault weapons. Illinois also enforces waiting periods for firearm purchases, requiring a specific amount of time to pass before a buyer can take possession of a firearm.


The Role of the FOID Card and Concealed Carry License

What is a Firearm Owner’s Identification (FOID) Card?

A firearm owner’s identification card is a requirement for Illinois residents who wish to possess firearms or purchase ammunition. Issued by the Illinois State Police, the FOID card ensures that firearm owners have passed background checks and are legally allowed to possess firearms under state law.

To obtain a FOID card, applicants must meet eligibility requirements, such as not being convicted of a felony, not having a history of mental health issues requiring court-ordered treatment, and not being subject to certain restraining orders.

What is a Concealed Carry License?

A concealed carry license allows Illinois residents to carry a concealed firearm in public. To obtain a concealed carry license, individuals must complete firearm training, pass a background check, and submit an application to the Illinois State Police. Unlike the FOID card, the concealed carry license allows for the carrying of a concealed firearm in certain public areas, although some locations remain off-limits.

Certain locations, such as government buildings, schools, and public transportation, are prohibited locations for carrying firearms, even with a valid concealed carry license.


Key Firearm Restrictions Under Illinois Gun Laws

Prohibited Locations for Firearms

Even with a concealed carry license, carrying firearms in specific places is prohibited. These locations include:

  • Government buildings
  • Schools and child care facilities
  • Public transportation vehicles and terminals
  • Bars and establishments where alcohol sales exceed a certain percentage of revenue

These locations are considered sensitive areas where public safety concerns outweigh the rights of gun owners to carry firearms.

Waiting Periods for Firearm Purchases

Illinois enforces a mandatory waiting period before transferring ownership of a firearm. The waiting period is 72 hours for both handguns and long guns, allowing time for background checks and a “cooling-off” period.

Assault Weapons Ban

Illinois has restrictions on certain types of firearms classified as assault weapons. The assault weapons ban limits the possession, transfer, and sale of these weapons. The Illinois General Assembly has passed laws regulating these firearms, and violations can result in severe penalties.

Firearm Ownership for Certain Individuals

Illinois gun laws prohibit firearm ownership for specific individuals, including:

  • Those convicted of a felony
  • Individuals with certain mental health conditions, especially if they have been admitted to a mental health facility
  • Individuals subject to specific protective orders, such as those related to domestic violence

Criminal Charges Related to Firearms

Violating Illinois firearm laws can lead to significant criminal charges. Some of the most common gun-related offenses include:

  • Unlawful Use of a Weapon (UUW): This charge may be filed if an individual is found carrying a firearm without a valid FOID card or concealed carry license.
  • Aggravated Assault: If a person demonstrates threatening physical behavior with a firearm, they may face aggravated assault charges.
  • Possession of a Firearm Without a FOID Card: Illinois residents who possess firearms without a valid FOID card can be charged with a misdemeanor or felony, depending on the circumstances.
  • Carrying a Concealed Firearm Without a License: Carrying a concealed firearm without a concealed carry license is a criminal offense that can result in severe penalties.

Penalties for Violating Illinois Gun Laws

Violating Illinois gun laws can lead to severe penalties, including fines, jail time, and permanent loss of firearm ownership rights. Penalties vary based on the nature of the offense, the type of firearm involved, and the individual’s prior criminal history.

Examples of potential penalties include:

  • Unlawful Use of a Weapon: Can result in felony charges, especially if a person possesses a firearm in a prohibited location.
  • Possession of a Stolen Firearm: If law enforcement officers determine that a person is in possession of a stolen firearm, they may face criminal charges, fines, and prison time.
  • Aggravated Domestic Battery: If a firearm is used in a domestic violence incident, the charges may be elevated to aggravated domestic battery, leading to more serious penalties.

How Law Enforcement and the Illinois State Police Enforce Gun Laws

Illinois gun laws are enforced by state and local law enforcement agencies, including the Illinois State Police. Law enforcement officers play a critical role in ensuring compliance with firearm laws, conducting background checks for FOID and concealed carry license applicants, and investigating cases of gun-related offenses.

The Illinois State Police are responsible for issuing and revoking FOID cards and concealed carry licenses. If a person is found to be a present danger due to physical or verbal behavior, their FOID card and concealed carry license may be revoked. Law enforcement officers can also seize firearms from individuals deemed a clear and present danger to themselves or others.


How Firearm Laws Affect Gun Ownership in Illinois

Illinois firearm laws impose strict requirements on gun ownership. For example, parents or legal guardians must provide written consent for minors under 21 to obtain a FOID card. Additionally, non-Illinois residents may face additional restrictions when transporting firearms through the state.

The Illinois Department of State Police works with mental health professionals to assess individuals who may pose a danger due to mental health issues. If a person has been admitted to a mental health facility or is determined to demonstrate threatening physical behavior, their ability to possess firearms may be revoked.


Gun-Related Offenses and the Role of the Courts

Gun-related offenses often require individuals to appear in the circuit court, where a judge will review the case and determine penalties. Individuals charged with a gun-related offense have the right to a fair trial, and the court will examine whether the person violated Illinois or federal law.

The role of the Illinois General Assembly and the Supreme Court is also significant in shaping firearm laws. Court rulings and new legislation can impact how firearm laws are enforced and what rights gun owners have.
