Updated September 2026 | The Bulldog Law | California Criminal Defense

Penal Code 415, disturbing the peace, punishes three things: unlawfully fighting or challenging someone to fight in a public place, willfully and maliciously disturbing others with loud and unreasonable noise, and using offensive words in public that are inherently likely to provoke an immediate violent reaction. The maximum is 90 days in county jail and a $400 fine, but the offense can be charged or reduced to an infraction, which is a fine with no criminal conviction. It is the most common plea-down in California criminal court, because it carries almost none of the consequences that attach to the battery, domestic violence, or resisting charges it usually replaces.

The Bulldog Law's attorneys ask prosecutors for a 415 more often than we ask for any other resolution, and we defend 415 charges filed on their own far less often, because the offense is rarely worth a prosecutor's time by itself. Both facts come from the same place: the statute is narrow, the penalties are light, and the collateral consequences are close to nothing. What follows is what the statute actually covers, the defenses when it's charged directly, how it works as a plea, and the single trap inside a 415 plea that catches people in domestic cases.

The three ways to disturb the peace

Penal Code 415 has three subdivisions, and a charge has to fit one of them. A shouting match that isn't a fight, isn't noise, and isn't fighting words is not a crime, however unpleasant.

Fighting or challenging to fight in public

The first subdivision reaches anyone who unlawfully fights, or challenges another person to fight, in a public place. Unlawfully matters: a fight in self-defense is not unlawful, and a consensual sparring match in a gym is not public. The public-place element covers streets, parking lots, bars, parks, and the common areas of apartment complexes. Two people who square up in a bar parking lot have each committed this offense, whether or not a punch lands; if one does, the charge becomes battery and the 415 becomes the plea target.

Loud and unreasonable noise

The second subdivision requires that the defendant maliciously and willfully disturb another person by loud and unreasonable noise. Three words carry the defense. Maliciously means the defendant intended to annoy or disturb, or acted in reckless disregard of the fact that the noise was disturbing; a person who didn't know the neighbors could hear the stereo hasn't acted maliciously until told. Unreasonable is judged objectively, by time, place, and the sensibilities of a normal person, not the one neighbor who complains about everything. And disturb another person requires an actual person who was disturbed, which is why police typically warn first and cite only when the noise continues. Municipal noise ordinances, with their decibel limits and curfews, handle most loud parties; a 415 noise charge usually means someone kept going after the warning, or the noise was itself the point.

Fighting words

The third subdivision punishes offensive words used in a public place that are inherently likely to provoke an immediate violent reaction. The First Amendment shapes this one heavily. Since Cohen v. California in 1971, offensive language on its own, even language most people find vile, is protected; what the statute reaches is speech directed at a particular person, in circumstances where a reasonable person would expect it to start a fight right then. California courts look at the words, the tone, the distance, and the setting. Calling a police officer names from across a parking lot is not fighting words. Getting in someone's face and daring them to do something about it may be. When the target was an officer, our attorneys note that officers are expected to tolerate more than civilians, and courts have said so.

Penalties: misdemeanor on paper, infraction in practice

The statute sets a maximum of 90 days in county jail, a $400 fine, or both, which makes disturbing the peace a misdemeanor. Under Penal Code 17(d), a prosecutor can file it as an infraction, or a judge can reduce it to one at arraignment or later, and an infraction is not a crime: no jail exposure, no probation, no criminal conviction, just a fine. Most first-offense 415 citations for noise and fighting words are resolved that way. The difference between an infraction and a misdemeanor is the difference between a traffic-ticket record and a criminal one, and for a client whose only exposure is a 415, our attorneys' first ask is the reduction.

Where the charge stays a misdemeanor, the realistic outcomes for a first offense are a small fine, informal probation, an anger management class, or dismissal after a period of good conduct through diversion. Jail is rare. A conviction can later be dismissed under Penal Code 1203.4, a process our page on expungement explains.

School grounds: Penal Code 415.5

The same three kinds of conduct on the grounds of a school, community college, or university are a separate offense under Penal Code 415.5, with the same 90-day and $400 maximum for a first offense but mandatory minimum jail terms for repeat violations, and an exemption for registered students and employees of the school. Our attorneys cover it on our Penal Code 415.5 page.

Defenses when 415 is the charge

First Amendment. In fighting-words cases, the defense usually is the Constitution. Offensive, rude, profane, and insulting speech is protected unless it meets the narrow standard above, and prosecutors who file 415 for a person who cursed at an officer or a neighbor frequently drop it when the motion is filed.

Self-defense. A person who fought because they were attacked did not fight unlawfully. This defense turns on who started it and whether the response was proportionate, and it's the same analysis our attorneys run in assault and battery cases, with the same evidence: video, witnesses, and injuries.

No malice, no unreasonableness. In noise cases, the absence of a warning, a complaint from a single hypersensitive neighbor, a noise level normal for the time and place, or noise the defendant didn't realize was carrying all defeat one element or another.

Not public. A fight or an exchange inside a private home, out of public view, is not within the first or third subdivision, although it may be something else.

The stop. A 415 investigation that began with an officer detaining someone without reasonable suspicion produces suppressible evidence, and a 415 charge added to a resisting or obstruction case is often the weakest count in the complaint. Our list of signs of a weak case applies to these small cases exactly as it does to large ones.

PC 415 as a plea: why everyone wants it

This is the part of the statute that matters most. When a prosecutor has a case they can't or don't want to try, but won't dismiss outright, the answer is often a plea to 415. Our attorneys negotiate them from simple battery, domestic battery, spitting and shoving cases like the ones on our spitting-as-battery page, public intoxication, drunk-in-public-adjacent DUI facts, trespass, and resisting arrest. The reasons a 415 plea is valuable, compared to the charge it replaces:

It is not a crime of violence, so it doesn't count as one for any purpose. It is not, by its terms, a domestic violence offense, so no firearm ban and no protective order flow from the code section. It is not a crime involving moral turpitude for immigration purposes, and it is one of the few pleas our immigration attorneys will sign off on without hesitation, subject to the trap below; our page on immigration consequences explains why the code section matters so much. It can be reduced to an infraction. And a no contest plea to a 415 misdemeanor can't be used against you in a civil suit, which matters when the underlying incident was a fight.

The trap in a domestic case

Here is the caveat every defense lawyer should know and some don't. When a 415 plea resolves a case that arose from a domestic incident, the court can find that the offense involved a relationship covered by Family Code 6211, spouse, partner, co-parent, cohabitant, and if it does, Penal Code 1203.097 attaches: a minimum three-year probation term, the 52-week batterer's intervention program, a protective order, and fees, regardless of the fact that the plea was to 415 rather than a domestic violence statute. A 415 plea in a DV case is still a good result in most situations, because it avoids the code section that triggers immigration and firearm consequences, but it is not a way around the batterer's program unless the plea agreement expressly says the 1203.097 terms do not apply and the judge accepts that. Our attorneys negotiate that language into every domestic 415 plea, and we tell clients before they sign whether the program is coming.

Frequently asked questions

What is disturbing the peace in California?

Penal Code 415 covers three things: fighting or challenging someone to fight in a public place, willfully and maliciously disturbing others with loud and unreasonable noise, and using offensive words in public that are inherently likely to provoke an immediate violent reaction. That's the whole statute. Yelling at your neighbor, playing music late, or squaring up outside a bar are the classic fact patterns.

Is disturbing the peace a misdemeanor or an infraction?

It can be either. The statute allows up to 90 days in county jail and a $400 fine, which makes it a misdemeanor, but prosecutors and judges can treat it as an infraction under Penal Code 17(d), which means a fine and no criminal conviction. In practice most first-time 415 cases end as infractions or are dismissed after a period of good behavior.

Why do lawyers call PC 415 a good plea?

Because it is one of the few charges in California that carries almost no collateral weight. It is not a crime of violence, not a domestic violence offense by itself, not a crime of moral turpitude for immigration, carries no firearm ban, and can be reduced to an infraction. Prosecutors use it to resolve battery, domestic battery, public intoxication, and resisting cases where they don't want to dismiss but can't prove much. The plea has one trap: if the court finds the underlying incident was domestic violence, the batterer's program requirement in Penal Code 1203.097 can attach even to a 415 plea.

Can I be charged with disturbing the peace for loud music?

Yes, but the statute requires the noise to be loud and unreasonable and the conduct to be willful and malicious, meaning you intended to disturb someone or acted in reckless disregard of the disturbance. A party that goes late is usually handled with a warning and, at most, a municipal noise citation. A 415 charge for noise generally requires that you were warned and kept going, or that the noise was clearly meant to provoke.

Does disturbing the peace go on your record?

If it's charged and resolved as an infraction, there is no criminal conviction and nothing to expunge; it appears in court records like a traffic ticket. If it's a misdemeanor conviction, it goes on your record but is eligible for dismissal under Penal Code 1203.4 once probation or the sentence is complete. Many 415 cases are dismissed outright through diversion, which leaves no conviction at all.
