Petaluma's Public Conduct: The Rules That Matter

Every city handles public conduct a little differently. In Petaluma, California, there are 8 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Loud Party Ordinance

Petaluma's Social Host Ordinance, Chapter 10.64, makes it unlawful for anyone with a right of possession of a property to knowingly host or allow an underage or unruly gathering where alcohol reaches a minor. Property owners, tenants and event organizers face criminal, civil and administrative penalties plus the city's police response costs.

Key details: Underage threshold: Under 21 years old. Misdemeanor penalty: Up to $1,000 and 6 months. Infraction penalty: Up to $500 per offense. Repeat-call liability: Joint and several. Written warning deadline: Within 30 days of citation.

A first violation is a misdemeanor punishable by up to a $1,000 fine and six months in jail, or, at the city attorney's discretion, an infraction capped at $500 per offense (10.64.080). Violations are also declared public nuisances that can be pursued civilly or administratively, with each day of the gathering a separate violation (10.64.090), and once police issue a citation and written warning, all responsible persons become jointly and severally liable for the city's response costs on any repeat call within twelve months (10.64.110).

Compared to other cities, Petaluma takes a harder line on loud party ordinance. The enforcement and penalty structure reflects that.

Outdoor Smoking Restrictions

Petaluma bans smoking in the unenclosed areas of public places, plazas, recreation areas, open space, service areas and dining areas across the city, not just indoors. The ban even reaches within twenty feet of a working road or construction crew, and it applies to e-cigarettes and vaping under the code's broad definition of smoking.

Key details: Banned outdoor areas: plazas, recreation areas, open space, dining areas. Construction buffer: 20 ft of a working road/crew. Designated smoking area cap: 10% of unenclosed area. Buffer from smoke-free doorways: 20 feet. Covers: vaping and e-cigarettes.

Violating the outdoor smoking ban is declared a public nuisance under Section 8.20.130(E) and enforced through Chapters 1.10 through 1.16, with each instance of unlawful smoking counted as a separate violation; premises where smoking is prohibited must post a 'No Smoking' sign under Section 8.20.100, but the absence of a sign is not a defense to a citation.

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

Public Marijuana Use

Petaluma's smoking ordinance defines smoking broadly enough to cover marijuana, treating it the same as tobacco: the code bans lighting up 'tobacco or any other weed or plant' inside every place of employment and enclosed public place other than a bar. That sweeps marijuana joints, pipes and vape devices into the same enclosed-area smoking ban that covers cigarettes.

Key details: 'Smoking' covers: tobacco or any other weed or plant. Banned in: enclosed public places, workplaces. Bars exempted: from the enclosed-place ban. Each incident: a separate violation. Enforcing authority: city manager or designee.

Smoking marijuana in a location covered by Section 8.20.040 is declared a public nuisance and a violation under Section 8.20.130(E), enforceable through Chapters 1.10 through 1.16; each instance of prohibited smoking is treated as a separate violation, and the city manager or a designee acts as the administrative authority who investigates citizen complaints and can issue citations.

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

Jaywalking

In Petaluma's central traffic district and any business district, pedestrians must cross the roadway at a marked crosswalk rather than mid-block. The traffic engineer designates where crosswalks exist and may post signs barring their use at a specific intersection.

Key details: Governing chapter: PMC Ch. 11.36 Pedestrians. Crossing rule: Crosswalk required in central/business districts. Minimum block for mid-block crosswalk: 400 feet. District defined at: PMC § 11.04.030. Enforcing agency: Petaluma Police Department.

A pedestrian who crosses outside a marked crosswalk in the central traffic district or a business district is subject to citation under Chapter 11.36. The chapter carries no chapter-specific fine schedule of its own; violations of Title 11 are processed under the city's general traffic-infraction procedures and bail schedule.

Skateboarding Rules

Petaluma bans skateboarding on public streets, sidewalks, parks and publicly owned buildings unless the rider follows nighttime reflective-gear, no-roadway and right-of-way rules, and bans it outright in the central business district and 13 named shopping centers.

Key details: General rule: No skating on streets/sidewalks without following 5 conditions. Business district: Skateboarding banned outright downtown. Named shopping centers: 13 centers listed as no-skate zones. Skate park gear: Helmet, knee pads, elbow pads required. Adopting ordinance: Ordinance 2270 NCS (2007).

PMC § 11.76.040 makes violations enforceable under 'any applicable laws or ordinances, including, but not limited to, Chapter 1.10 of this code.' A first skate-park protective-equipment violation under § 11.76.050 is an infraction; a subsequent violation may be charged as an infraction or a misdemeanor under Chapter 1.10.

This is not one of those rules that cities tend to ignore. Petaluma actively enforces its skateboarding rules requirements.

Public Urination

Petaluma Municipal Code section 10.16.020 makes it unlawful for anyone over the age of ten to willfully urinate or defecate in a public place or anywhere exposed to public view, and separately bans exposing oneself for that purpose in a way that displays the genitals, buttocks or anal region to public view.

Key details: Governing section: PMC § 10.16.020. Minimum age covered: Over 10 years old. Default misdemeanor fine: Up to $1,000. Default jail term: Up to 6 months. Infraction fine (1st offense): Up to $100.

Because section 10.16.020 carries no penalty clause of its own, a violation defaults to the general penalty schedule in section 1.12.020: a misdemeanor punishable by a fine of up to $1,000, imprisonment in county jail for up to six months, or both, unless the citing officer or city attorney elects to charge it as an infraction, which is capped at $100 for a first offense and $200 for a second offense within a year.

Loitering Rules

Petaluma Municipal Code section 10.60.010 makes it unlawful to loiter on private commercial property after business hours without the owner's permission, but the city only enforces the chapter once the affected property owner or business operator has filed a written request asking it to do so.

Key details: Governing sections: PMC §§ 10.60.010, 10.60.020. Property type covered: Private commercial property only. Enforcement trigger: Written request from owner. Classification: Infraction, not misdemeanor. First-offense fine cap: Up to $100.

Section 10.60.020 classifies any violation of the chapter as an infraction, not a misdemeanor, so a person cited for loitering on private commercial property after hours faces a fine rather than jail time; under the code's general infraction schedule in section 1.12.020(C), that fine is capped at $100 for a first violation and $200 for a second violation of the same section within a year, with a third violation chargeable as a misdemeanor.

Petaluma is more permissive than most cities when it comes to loitering rules. That said, there are still limits.

Public Alcohol Use

Petaluma bans possessing an opened alcoholic beverage container or consuming alcohol in any city park the city manager has designated and posted as alcohol-prohibited, unless the person holds a permit from the parks and recreation department.

Key details: Governing section: PMC § 13.28.185. Trigger: Designated + posted park, no permit. Designation authority: City manager. Commission review: Recreation, music & parks commission. Related ban: Glass containers, all parks, §13.28.180(N).

Possessing an open alcoholic beverage container or consuming alcohol in a park designated and posted under Section 13.28.185 without the required permit is a violation of the Petaluma Park Ordinance, enforceable by city park and police personnel who may cite offenders under the ordinance's general enforcement provisions.

This is not one of those rules that cities tend to ignore. Petaluma actively enforces its public alcohol use requirements.

If you are a homeowner, renter, or business owner in Petaluma, take the time to understand these requirements before they become a problem.
