How Costa Mesa Handles Public Conduct: A Practical Guide

Costa Mesa maintains 134 local ordinances across all categories, and 7 of those deal specifically with public conduct. Here is a breakdown of what the city actually requires, what is prohibited, and where Costa Mesa falls on the strict-to-permissive spectrum compared to other cities.

Skateboarding Rules

Costa Mesa confines lawful skateboarding and roller skating to designated skate parks under Article 2 of Title 12. Riders must wear posted safety gear, stay off wet surfaces, and follow 15 listed rules; three infractions bar a rider from any skate park for good.

Key details: Where allowed: Designated skate parks only (Sec. 12-56). Required gear: Helmet, elbow pads, knee pads. Wet surface: Riding prohibited. Devices barred: Bicycles, scooters, motorized devices. Impound: Officers may seize board/skates on-site.

A skate park violation is charged as an infraction or misdemeanor, at the city attorney's or district attorney's discretion, with each day of a continuing violation counted separately. Officers can impound the rider's skateboard, bicycle, scooter or roller skates on the spot, reclaimable free at the police department within 60 days before disposal by destruction or auction. Three convicted infractions mean a permanent ban from every Costa Mesa skate park.

Jaywalking

Costa Mesa pedestrians must use a marked crosswalk between intersections controlled by a traffic signal or a police officer, under Municipal Code Section 10-168. Following a 2024 rewrite tracking the state's Freedom to Walk Act, an officer cannot stop a pedestrian for mid-block crossing unless a reasonably careful person would see an immediate danger of colliding with a moving vehicle.

Key details: Governing section: Municipal Code § 10-168. Rule scope: Signal-controlled intersections only. Officer stop limit: Only if immediate collision danger. Related median ban: § 10-169, misdemeanor. Standard infraction fine: Up to $100 first offense.

Ordinary mid-block crossing outside a signal-controlled intersection is not enforced unless a reasonably careful officer would see immediate danger of a vehicle collision; when it is cited, it is an infraction under the general Section 1-33 schedule ($100 first offense, $200 second, $500 thereafter within a year). Standing or sitting on a center median is treated more seriously as a misdemeanor, punishable by up to a $1,000 fine, up to six months in jail, or both, and the city attorney can pursue civil abatement.

If you are coming from a city with tighter rules, you will find Costa Mesa gives residents more flexibility on jaywalking.

Loud Party Ordinance

Costa Mesa doesn't fine a loud party the first time. Under sections 11-170 through 11-172, once police issue a written warning for a large party, gathering or event that threatens public peace, health or safety, a second call within 30 days makes the person responsible for the event personally liable for the full cost of the special police response, with the city reserving the right to bill anything over $500.

Key details: Governing sections: Sec. 11-170 to 11-172. Adopted: Ordinance No. 91-26, Oct. 1991. Trigger: second police response within 30 days. Liable party: event's responsible person or organizer. Minor host: parents/guardians jointly liable.

There's no citation for a first loud-party call under this chapter; the exposure begins only after a documented written warning. A second police response to the same address within 30 days makes the responsible adult, or a minor's parents, personally liable for the full special-assignment police services fee, which the city can pursue as a civil debt through the city attorney, including recovery of its attorneys' fees, separate from any misdemeanor citations issued for actual code or Penal Code violations found on scene.

Aggressive Panhandling

Costa Mesa bans asking, begging or soliciting alms in an aggressive manner anywhere open to the public, from sidewalks and parking lots to gas stations and fast-food drive-through lanes. Section 11-177 defines aggressive manner to include touching, blocking someone's path, following after a refusal, or unsolicited car washing followed by a demand for payment.

Key details: Governing sections: Sec. 11-177 to 11-181. Adopted: Ordinance No. 95-4, March 1995. Banned conduct: aggressive manner only, not begging itself. Covers: sidewalks, lots, gas stations, drive-throughs. Penalty: misdemeanor, up to $1,000/6 months.

A violation is a misdemeanor punishable under section 1-33(b), up to a $1,000 fine, up to six months in jail, or both. Section 11-180 also lets the city attorney treat any violation as a public nuisance, pursued through civil process by a restraining order or injunction rather than, or in addition to, criminal prosecution; constitutionally protected picketing and protesting remain exempt throughout.

This is not one of those rules that cities tend to ignore. Costa Mesa actively enforces its aggressive panhandling requirements.

Public Alcohol Use

Costa Mesa Municipal Code section 11-3 bans drinking wine, beer, whiskey, brandy or any alcoholic beverage on public streets, alleys, sidewalks, parkways, in public restrooms, parking lots, vacant lots and parked vehicles, and in city parks. The only way around it is a specific park area the city council has expressly approved and posted for drinking; everywhere else in public, an open container is a citation waiting to happen.

Key details: Governing section: Section 11-3, Costa Mesa Municipal Code. Covers: streets, parks, parked vehicles, restrooms. Exception: council-posted park area only. First infraction fine: up to $100. Misdemeanor penalty: up to $1,000 fine, 6 months jail.

Officers cite a first public-drinking violation under section 11-3 as an infraction: up to $100 for a first offense, $200 for a second within a year, and $500 for each further offense in that year, under the citywide schedule in section 1-33. Police can instead charge a misdemeanor, punishable by a fine up to $1,000, up to six months in county jail, or both, and open containers can be seized as evidence.

Compared to other cities, Costa Mesa takes a harder line on public alcohol use. The enforcement and penalty structure reflects that.

Public Urination

Costa Mesa Municipal Code section 11-4 makes it unlawful to urinate, defecate or dispose of human waste on private property visible to the public, or on any public street, sidewalk, alley, park, parkway or parking lot, unless it happens inside a proper toilet in a restroom or enclosure. A genuine illness or physical infirmity is a defense; being drunk or high is explicitly not.

Key details: Governing section: Section 11-4, Costa Mesa Municipal Code. Adopted: Ordinance No. 91-3, Feb. 1991. Covers: public property and publicly visible private property. Medical exemption: illness or physical infirmity only. Intoxication defense: expressly not exempt.

Most first-time citations under section 11-4 are written as infractions under the citywide schedule in section 1-33: up to $100 for a first offense, $200 for a second within a year, and $500 for each further offense. Because the code excludes an intoxication-based defense, officers can instead pursue a misdemeanor charge, carrying a fine of up to $1,000, up to six months in county jail, or both.

Compared to other cities, Costa Mesa takes a harder line on public urination. The enforcement and penalty structure reflects that.

Outdoor Smoking Restrictions

Smoking is banned in every Costa Mesa park, within 50 feet of any park perimeter, and in all city-owned public facilities under Municipal Code § 8-133. The ban also covers the parking lots and enclosed fenced areas of city sports complexes and community gardens, wherever posted with no-smoking signs.

Key details: Park buffer: 50 feet from any park perimeter. Covers: Tobacco, e-cigarettes, any smoked substance. Repeat violations: 3+ in 12 months = public nuisance. Stay-away order: Up to 12 months from facility. Litter rule: Butt disposal banned in no-smoking zones.

A first violation of § 8-133 is punishable under § 1-33 and can also result in immediate ejection from the park by an authorized city employee under § 8-135.1(b). Three or more violations by the same person within any 12-month period at the same park, sports facility or community garden is declared a public nuisance under § 8-135.1(c), enforceable by injunction or restraining order, and the violator can be barred from that facility for up to 12 months.

This is one of the stricter rules in Costa Mesa's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

The Bottom Line

Costa Mesa is tougher than many cities when it comes to public conduct. Out of the 7 rules covered here, 4 are rated strict. If you are a homeowner, renter, or business owner in Costa Mesa, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.
