Public urination laws in California don’t live in a single statute. The consequences range from a $50 infraction in some cities to a misdemeanor with jail exposure under state law, and in the worst case an indecent exposure charge that puts you on the sex offender registry. Which end of that range you land on depends on the city where it happened, what a prosecutor believes you were doing, and your record.
How the Charge Gets Chosen
There is no statewide statute specifically banning public urination. Cases are handled through a patchwork: local municipal ordinances first, and broader state criminal laws when prosecutors believe the situation warrants more.
The paths a case can take:
- A local city ordinance, usually an infraction or low-level misdemeanor.
- Penal Code 372, the general public nuisance misdemeanor.
- Penal Code 640, which covers transit vehicles and stations.
- Penal Code 314, indecent exposure, if prosecutors allege lewd intent.
What tips a case from one bucket to the next is context: where it happened, who saw it, whether you appeared to be deliberately exposing yourself, and your prior history.
City Ordinance Penalties
Most cases stay at the city level, and cities handle it very differently.
Los Angeles
Los Angeles Municipal Code Section 41.47.2 prohibits urinating or defecating on any public street, sidewalk, alley, park, beach, public building, or any place open to or exposed to public view. The only carve-out is for using an actual restroom, portable toilet, or similar enclosed facility.1Los Angeles City Clerk. Los Angeles Municipal Code Section 41.47.2 – Urinating or Defecating in Public Violations are generally treated as misdemeanors.
San Francisco
San Francisco Police Code Section 153 treats public urination as an infraction. Fines run from $50 to $500.2American Legal Publishing. San Francisco Police Code SEC. 153 – Urination and Defecation An infraction does not create a criminal record, which makes San Francisco meaningfully lighter than cities that charge the same conduct as a misdemeanor.
If you were cited somewhere else in the state, check that city’s municipal code. Classifications and fine amounts vary widely.
State-Level Misdemeanor Charges
Public Nuisance: Penal Code 372
Prosecutors can charge public urination as a public nuisance under Penal Code 372, which makes it a misdemeanor to commit any public nuisance not covered by a more specific statute.3California Legislative Information. California Penal Code 372 – Public Nuisance Under Penal Code 19, a standard misdemeanor carries up to six months in county jail, a fine of up to $1,000, or both.4California Legislative Information. California Penal Code 19 – Punishment for Misdemeanor This charge tends to come up when the incident happened in a high-traffic area or when the conduct was repeated.
Transit Systems: Penal Code 640
Urinating or defecating inside a transit vehicle or facility, meaning a BART station, Metro bus, or similar system, is a separate offense under Penal Code 640. The penalty is a fine of up to $400, up to 90 days in county jail, or both. The statute has a built-in exception for anyone who cannot comply because of a disability, age, or medical condition.5California Legislative Information. California Penal Code 640 – Transit System Offenses
When It Becomes Indecent Exposure
This is the scenario worth understanding even though it rarely applies to a typical case. If a prosecutor believes you willfully and lewdly exposed yourself, the charge can jump to indecent exposure under Penal Code 314. A first conviction is a misdemeanor. A second conviction, or a first conviction if you have a prior conviction for certain sex offenses, becomes a felony punishable by state prison.6California Legislative Information. California Penal Code 314 – Indecent Exposurep>
The word doing the work in the statute is “lewdly.” Prosecutors must show you intended to draw sexual attention or gratify yourself, not simply that you needed a restroom and picked the wrong spot. Most straightforward public urination cases don’t meet that threshold. Circumstances that push a case there include urinating in the direction of people, exposing yourself longer than necessary, or doing so near children.
What makes Penal Code 314 dangerous is what follows a conviction: mandatory sex offender registration under Penal Code 290. California explicitly lists Section 314 as a registerable offense.7California Legislative Information. California Penal Code 290 – Sex Offender Registration Registration puts your name on a public database, requires you to update your address with law enforcement, and follows you into employment, housing, and travel for years.
Defenses Worth Raising
Which defense fits depends on the charge, but several apply broadly.
- No lewd intent. If prosecutors reach for indecent exposure, the central defense is that you had no sexual or exhibitionistic purpose. You were relieving yourself and tried to be discreet. The line between biological urgency and lewd behavior is often the whole case.
- Medical necessity. Conditions like Crohn’s disease, ulcerative colitis, irritable bowel syndrome, or an overactive bladder can make waiting impossible. Documentation of a diagnosed condition supports the defense, and Penal Code 640 builds this in for transit cases by exempting anyone unable to comply because of a disability, age, or medical condition.5California Legislative Information. California Penal Code 640 – Transit System Offenses
- Not a public place. If the location was not visible to the public and doesn’t meet the ordinance’s definition of a public place, the charge may not hold. Witness testimony, surveillance footage, or the physical layout can establish that.
- No available restroom. Not a full defense on its own in most jurisdictions, but it can support reduced charges or dismissal when paired with a medical condition or other mitigation.
Restroom Access for Medical Conditions
California’s Restroom Access Act, Health and Safety Code Section 118702, gives people with certain medical conditions a right to use employee-only restrooms in retail stores. A retail business open to the public that has an employee restroom must allow access to individuals with qualifying conditions when no public restroom is immediately available.8California Department of Public Health. Restroom Access Act
Qualifying conditions include Crohn’s disease, ulcerative colitis, other inflammatory bowel diseases, irritable bowel syndrome, and any other condition requiring immediate restroom access. The business must have at least three employees on duty, and the restroom must be in a location that doesn’t create a health, safety, or security risk. The business can ask for a signed statement from a doctor or similar professional confirming your condition. A business that willfully or negligently refuses access faces a civil penalty of up to $100 per violation.8California Department of Public Health. Restroom Access Act
What Ends Up on Your Record
An infraction, like those issued under San Francisco’s ordinance, does not create a criminal record. A misdemeanor conviction does. It shows up on background checks and can affect employment, housing, and licensing.
An indecent exposure conviction under Penal Code 314 is a different category of problem because of the registration requirement. The registry is public, and it creates ongoing barriers to employment involving children or vulnerable populations, restricts where you can live, and complicates professional licensing.
Clearing a Conviction Under Penal Code 1203.4
If you were convicted of a misdemeanor for public urination and placed on probation, Penal Code 1203.4 lets you petition the court for dismissal once probation is complete. The court can allow you to withdraw your guilty plea, enter a not guilty plea, and dismiss the case, releasing you from most penalties tied to the conviction.9California Legislative Information. California Penal Code 1203.4 – Dismissal of Accusation or Information
To qualify, you must have finished probation, not currently be serving a sentence or facing new charges, and give the prosecutor at least 15 days’ notice. Unpaid restitution alone cannot be the reason for denial.9California Legislative Information. California Penal Code 1203.4 – Dismissal of Accusation or Information
Dismissal isn’t a full erasure. You still have to disclose the conviction when applying for public office or a license from a state or local agency, and the prior conviction can still be used against you if you are prosecuted for a new offense later.9California Legislative Information. California Penal Code 1203.4 – Dismissal of Accusation or Information Infractions are not eligible under this section, but since they don’t create a criminal record, there is usually nothing to clear.
