What Is a Class C Misdemeanor in Illinois?
Illinois law divides criminal offenses into two broad categories: felonies and misdemeanors. Felonies carry potential prison sentences of one year or more, served in a state facility. Misdemeanors are less severe and, if jail time is imposed, are served in a county jail.
Within the misdemeanor category, Illinois recognizes three classes. Class A is the most serious, followed by Class B, then Class C. Sentencing guidelines for each class are established under the Illinois Compiled Statutes, with Class C governed by 730 ILCS 5/5-4.5-65.
A
Class A Misdemeanor
- Max jail: 364 days
- Max fine: $2,500
- Common charges: DUI (1st & 2nd offense), domestic battery, battery, retail theft, UUW
B
Class B Misdemeanor
- Max jail: 180 days
- Max fine: $1,500
- Common charges: Cannabis possession (10–30g), criminal trespass, aggravated speeding (26–34 mph over)
C
Heading
- Max jail: 30 days
- Max fine: $1v,500
- Common charges: Assault, disorderly conduct, improper firearm storage
“Least severe” is a relative term. A Class C conviction follows you the same way any criminal conviction does. Employers running background checks see a conviction, not a classification. That distinction matters when you are looking for a job, applying for an apartment, or renewing a professional license in Illinois.
Common Class C Misdemeanor Charges in Illinois
A small number of offenses are charged as Class C misdemeanors in Illinois. The two you are most likely to encounter are assault and disorderly conduct. A third, improper firearm storage accessible to a minor, comes up less frequently but carries its own mandatory minimum fine.
1
Assault
Under Illinois law, assault does not require physical contact. Under 720 ILCS 5/12-1, a person commits assault when they knowingly engage in conduct that places another person in reasonable apprehension of receiving a battery, without lawful authority to do so.
The phrase “reasonable apprehension” is the operative element. The question is not whether you intended to follow through. It is whether the other person had reasonable grounds to believe they were about to be struck or harmed. Threatening words, a raised fist, or an aggressive advance can all satisfy this standard depending on the circumstances.
Assault and battery are two distinct charges. Assault is the threat; battery is the contact. Many people use the terms interchangeably, but under Illinois law they are separate offenses with separate elements and separate consequences.
A conviction for assault also carries a mandatory community service requirement in addition to any other penalty the court imposes. Illinois law requires convicted defendants to perform a minimum of 30 hours and up to 120 hours of community service.
It is also worth understanding how quickly an assault charge can escalate. Depending on the circumstances, including the identity of the alleged victim, the use of a deadly weapon, or the location of the offense, the charge can be elevated to aggravated assault, which carries felony-level consequences. If you have been charged with any form of assault, the classification matters and should be reviewed by an attorney immediately.
2
Disorderly Conduct
Disorderly conduct is the most commonly charged Class C misdemeanor in Illinois. The statute at 720 ILCS 5/26-1 covers a range of conduct across multiple subsections. The subsection most often charged as a Class C misdemeanor involves knowingly acting in an unreasonable manner that alarms or disturbs another person and provokes a breach of the peace.
In practice, this charge tends to emerge from situations that escalated: a loud argument that spilled into a public space, a confrontation that a bystander reported to police, a noise complaint that crossed from civil annoyance into criminal territory. The statute is deliberately broad, which gives prosecutors flexibility in how they apply it and gives defense attorneys room to challenge whether the conduct actually met the legal standard.
Other subsections of the disorderly conduct statute carry higher classifications, up to and including felony charges. The specific subsection you are charged under determines the severity of your case.
3
Improper Storage of a Firearm Accessible to a Minor
This charge applies when a person stores or leaves a firearm within premises under their control, knows or has reason to believe that a minor under the age of 14 without a Firearm Owners Identification card is likely to gain access to it, and that minor causes death or great bodily harm with the firearm.
A conviction carries a mandatory minimum fine of $1,000, separate from and in addition to the general Class C fine structure. This charge frequently surprises people who consider themselves responsible gun owners. The storage standard under Illinois law is specific, and failing to meet it when the consequences the statute describes occur results in a criminal charge regardless of intent.

Penalties for a Class C Misdemeanor in DuPage County
The maximum penalties for a Class C misdemeanor under Illinois law are up to 30 days in the DuPage County jail, a fine of up to $1,500 plus mandatory court costs, and probation or conditional discharge for up to two years. The court may also impose court supervision, which is explained in detail below and is the most consequential sentencing alternative available.
For most first-time offenders facing a Class C charge, a 30-day jail sentence is not the realistic outcome. Courts consider prior history, the facts of the offense, and what the defendant has done since the charge. What matters most in practice is not avoiding the maximum penalty. It is avoiding a conviction altogether.
- If your case is dismissed or you are acquitted at trial, the arrest record can typically be expunged immediately under Illinois law.
- If you receive court supervision and complete it successfully, you are not convicted, and you become eligible for expungement after a waiting period with no new offenses, which destroys the record entirely.
- If you are convicted, your options narrow: most misdemeanor convictions are eligible for sealing after a three-year waiting period, which restricts public access but does not destroy the record, and law enforcement, certain employers, and licensing boards can still access it.
The path from charge to a clean record runs through supervision and expungement, not through conviction, and that path starts with how your case is defended from the beginning.

Court Supervision Outcomes for Class C Misdemeanors
Court supervision is not a conviction. It is a deferred judgment in which the court monitors compliance with certain conditions, typically no new arrests, payment of fines and costs, and completion of any required community service or treatment. If you complete supervision successfully, the charge is dismissed. You are not convicted.
For Class C misdemeanor defendants, particularly those with no prior record, this distinction is critical. A conviction produces a permanent criminal record. Supervision, completed successfully, does not. And because supervision is not a conviction, a successfully completed Class C supervision is eligible for expungement under Illinois law, which means the record can be cleared entirely.
This is the outcome a defense attorney should be working toward on most first-offense Class C charges: not just minimizing the penalty, but avoiding a conviction in the first place.
A conviction stays on your record
Even a Class C misdemeanor conviction is permanent. It will appear on background checks run by employers, landlords, and professional licensing boards throughout Illinois. Court supervision, completed successfully, is not a conviction, and it preserves your ability to seek expungement. The difference between these two outcomes is one of the most important reasons to retain an attorney before your first court date.
Collateral Consequences You May Not Have Considered
While the 30-day jail cap is the figure most people focus on when they look up Class C misdemeanor penalties, it is rarely what ends up affecting their life most.
The real consequences of a conviction tend to show up later: a job offer that disappears after a background check, a rental application that gets denied, a professional license that comes up for renewal with a conviction on the record. Illinois employers, landlords, and licensing agencies do not distinguish between misdemeanor classes when they see a criminal conviction. They see a record.
Professional licensing is a specific concern in Illinois. Nurses, teachers, real estate agents, contractors, and others in licensed fields can face disciplinary proceedings based on a criminal conviction, even a misdemeanor. If you hold a professional license or are pursuing one, a Class C conviction carries stakes beyond the courtroom.
First-time offender
Court supervision is likely within reach. A DuPage County defense attorney can pursue a supervision disposition that, if completed successfully, keeps a conviction off your record entirely and preserves your eligibility for expungement.
Prior record
The calculus changes for those with prior records. Supervision may not be available, and a conviction carries compounding consequences on top of an existing record. Experienced representation is essential to understanding your realistic options and limiting the damage.

What to Expect in DuPage County Court
Class C misdemeanor cases in DuPage County are heard in the Circuit Court of the 18th Judicial Circuit, which operates out of the courthouse in Wheaton. The process moves on a schedule that does not wait for you to get organized.
After an arrest or citation, you will receive a court date for an arraignment. At arraignment, you enter a plea and the case is scheduled forward. If you appear without an attorney, the fast-moving courtroom environment can leave you feeling pressured to enter a plea before you have had the chance to understand your options or review the evidence against you.
Retaining an attorney before your first court date matters. Negotiations with the prosecution begin early, and the posture you take at arraignment affects how the rest of the case unfolds.

Frequently Asked Questions About Class C Misdemeanors
The maximum is 30 days in county jail, but for most first-time offenders facing a Class C charge, jail is not the likely outcome. Courts routinely impose court supervision, fines, or community service instead. The more immediate concern is whether a conviction ends up on your permanent record.
Class A is the most serious misdemeanor, carrying up to 364 days in county jail and fines up to $2,500. Class C is the least severe, with a maximum of 30 days in jail and fines up to $1,500. Both can produce a permanent criminal record on conviction. The classification affects the sentencing range, not whether a conviction has real-world consequences.
Yes, under certain conditions. If your case was dismissed, you were acquitted, or you received court supervision and completed it successfully, you are eligible to petition for expungement under 20 ILCS 2630/5 after the applicable waiting period. A conviction is not eligible for expungement but may qualify for sealing after three years. An attorney can review your specific situation and tell you what you qualify for.
You are not required to have one, but the consequences of getting it wrong are permanent. The difference between court supervision and a conviction is significant, and it is not a difference the court will walk you through. An attorney who knows how these cases are handled in DuPage County gives you the best chance of the outcome that keeps your record clean.
A conviction stays on your record permanently unless sealed or expunged. Sealing restricts public access but does not destroy the record. Expungement does, but it requires either a non-conviction outcome or a successfully completed supervision. The path to a clear record starts with how your case is resolved.
Yes. Employers in Illinois routinely run background checks, and a criminal conviction of any class can affect a hiring decision. For licensed professionals, including nurses, teachers, real estate agents, and contractors, a misdemeanor conviction can trigger a licensing review. The specific impact depends on the profession and the licensing board’s rules, but this is a risk that should factor into how aggressively you defend the charge.
If you violate the terms of supervision, the court can find that you have failed to complete it successfully and enter a conviction. That is the outcome supervision was designed to avoid. If you are on supervision and believe you may have violated a condition, contact your attorney immediately.
