Disturbing the Peace in Maryland: Penalties, Defenses, and Expungement

Disturbing the peace in Maryland is a misdemeanor under Section 10-201 of the Criminal Law Code, and a conviction carries up to 60 days in jail, a fine up to $500, or both.¹ The statute covers more than loud parties. It reaches obstruction of sidewalks, disorderly behavior in public, failure to obey a police order given to prevent a disturbance, and unreasonably loud noise from almost any location. Every one of those acts has to be willful for the charge to stick.

What the Statute Prohibits

Section 10-201 lists five specific behaviors, and prosecutors have to pick one to charge you under:

Willfully obstructing or hindering someone’s free passage in a public place or on public transportation without a lawful purpose.
Willfully acting in a disorderly manner that disturbs the public peace.
Willfully failing to obey a reasonable and lawful order from a police officer made to prevent a disturbance.
Willfully entering another person’s land or premises and making unreasonably loud noise or acting disorderly in a way that disturbs the people there.
Willfully making unreasonably loud noise that disturbs someone on their property, in a public place, or on public transportation.¹

Fighting, threats of violence, and inciting a crowd are not on that list. Those behaviors can be charged, but under separate Maryland criminal statutes with their own penalty ranges. Section 10-201 is narrower than its reputation suggests.

Why “Willfully” Matters

Every offense under Section 10-201 uses the word “willfully,” and it does real work. The prosecution has to prove you acted deliberately, not accidentally. A car alarm that malfunctions is not a willful act. A stereo cranked to full volume at 2 a.m. after a neighbor has already complained almost certainly is.

This is where many charges collapse. If the conduct was unintentional, or if the defendant genuinely did not know they were causing a disturbance, the state cannot meet its burden. Someone unknowingly blocking a sidewalk while loading a truck is in a much stronger position than someone planted in a doorway refusing to move.

What Counts as Unreasonably Loud

The statute does not set a decibel limit. Whether noise is “unreasonably loud” depends on the setting: the type of neighborhood, the time of day, how long it lasts, and whether it would bother a typical person in the same circumstances. A lawnmower at noon in a suburb is not the same lawnmower at midnight.

Many Maryland counties and municipalities layer their own noise ordinances on top of the state statute, and some of those do set decibel thresholds or quiet hours. A local ordinance violation can support a Section 10-201 charge, but the state law itself keeps the standard flexible. Courts ask whether the noise would disturb a reasonable person, not whether the complainant was unusually sensitive.

Disobeying a Police Order

Subsection (c)(3) catches people who are not otherwise breaking the law. Ignoring a reasonable, lawful order from an officer given to prevent a disturbance is itself an offense.¹ You can be charged even when your underlying conduct was legal.

The order has to be both reasonable and lawful. An officer telling a crowd to disperse after a fight is almost certainly lawful. An officer telling you to stop filming from a public sidewalk when nothing else is happening likely is not. If the order was unlawful or unreasonable, that is a direct defense to the charge, though what qualifies as “lawful” often turns on the specific facts and how a court sizes them up.

Penalties

The maximum sentence is 60 days in jail, a $500 fine, or both.¹ There is no enhanced penalty tied to location under this section; the same range applies whether the disturbance happened outside a school, a hospital, or a bar.

First-time offenders charged with a noise complaint or minor disorderly conduct rarely see the ceiling. Judges have room to impose probation, community service, or a fine well below $500. Repeat offenders and cases where real harm or fear resulted draw stiffer sentences within the same range. Prosecutors sometimes offer probation before judgment, which avoids a formal conviction on your record if you complete the probation terms successfully.

Hiring a private defense attorney for this kind of misdemeanor typically runs between $1,500 and $5,000, depending on complexity and how far the case goes.

Defenses That Actually Work

The strongest defense depends on which subsection you are charged under. Common approaches include:

Lack of willfulness. If the conduct was accidental, or you did not realize you were causing a disturbance, the state cannot prove the mental state the statute requires.
Lawful purpose. The obstruction provision only applies when the blocking is “without lawful purpose.” A delivery driver briefly blocking a sidewalk to unload has a lawful purpose.
The noise was not unreasonable. Context is everything. Construction noise during business hours in a commercial district is a hard sell as unreasonable; the same noise at midnight in a residential block is not.
Unlawful police order. For charges under subsection (c)(3), challenging whether the officer’s order was reasonable and lawful goes to the heart of the offense.
Vagueness as applied. Because “disorderly manner” is not precisely defined, defendants sometimes argue the statute is unconstitutionally vague in their particular situation.

Protests, Speech, and the First Amendment

Public demonstrations and heated speech often look like a disturbance to observers. The First Amendment protects speech even when it is loud, obnoxious, or offensive, especially on matters of public concern in public places.² Government cannot punish words simply because they upset the audience.

The narrow exception is “fighting words”: words directed at a specific person that are inherently likely to provoke an immediate violent reaction.² In practice the exception is extremely thin. Profanity, vulgarity, and personally offensive remarks generally remain protected unless they cross into direct, face-to-face provocation likely to trigger immediate violence.

For someone charged after a protest, the strongest argument is usually that the disruptive conduct was incidental to protected speech rather than aimed at causing disorder. A protest that briefly blocks a sidewalk can still generate a charge, but courts weigh the constitutional interests heavily.

What a Conviction Does to Your Record

Even a low-level misdemeanor conviction under Section 10-201 shows up on background checks. Maryland recognizes collateral consequences of criminal convictions in areas including employment, professional licensing, voting rights, jury service, and firearms eligibility.³ For a disturbing the peace conviction, the practical hit usually lands on employment and licensing.

Professional licensing boards typically ask about misdemeanor convictions. They pay particular attention to offenses touching on honesty or violence, but any conviction can prompt closer review. Not disclosing a conviction when asked is generally worse than the conviction itself, because licensing boards have access to the same background databases as law enforcement. A candid explanation with evidence of rehabilitation often makes the difference. Employers running background checks may also read a disorderly conduct conviction as a judgment or reliability concern, and Maryland’s protections on the use of criminal records in hiring do not erase the fact that the conviction still appears in the screening.

Expungement

Section 10-201 is expressly listed among the offenses eligible for expungement in Maryland.⁴ Expungement removes the case from court and law enforcement records and takes it out of public view.⁵

The path depends on how the case ended:

If you were acquitted, the case was dismissed, or the state entered nolle prosequi, you can petition relatively quickly.
If you received probation before judgment and completed probation, you become eligible after a waiting period.
If you were convicted of obstructing free passage under Section 10-201, that offense falls within a category eligible for expungement after a three-year waiting period, measured from the later of the conviction or completion of the sentence, including probation.⁶

You file the petition in the circuit or district court in the county where the offense occurred.⁷ If granted, the court orders every agency holding records of the case to destroy or seal them. Keep copies of the petition, the order, and everything related, because once expungement is complete you may not be able to get copies of the original case records back.

Civil Liability Alongside Criminal Charges

A criminal charge is not the only exposure. Persistent noise or disruptive behavior can also draw a civil nuisance suit from affected neighbors or property owners. A nuisance claim does not require a criminal conviction; the affected party sues for damages tied to the interference with their use and enjoyment of their property, and can ask a court to order the behavior stopped. The civil case and the criminal case run on separate tracks, so a dismissal in criminal court does not shut the door on a neighbor pursuing damages.
