19.01.010 Purpose and Findings.¶
The City Council of the City of Larkspur does hereby find and declare all of the following:
A. The intent of this chapter is to protect the public health, safety and general welfare, rather than to punish;
B. The consumption of alcohol, the ingestion of controlled substances and the use or possession of marijuana by persons under the age of twenty-one (21) years is unlawful and presents a threat to the well-being of the minor and other persons having contact with the minor who has consumed alcohol or used controlled substances or marijuana;
C. Any party or gathering where the person owning or controlling the premises or event suffers or permits any minor to consume alcohol or ingest controlled substances and/or marijuana is being conducted in a manner that is not properly supervised or controlled and presents a threat to the public safety, health, and welfare;
D. Unsupervised parties on private or public property where alcohol, marijuana or controlled substances are consumed by minors constitute a potential hazard for the partygoers and those who might come into contact with them during the party or after the minor leaves the party and enters the public domain;
E. Control by the police of unsupervised parties, gatherings, or events as described above is necessary when such activity is determined to be a threat to the peace, health, safety, or general welfare of the public;
F. The occurrence of parties or gatherings as described above contributes to an increase in alcohol and drug abuse and driving under the influence by minors, excessive noise, traffic, and vandalism within the neighborhood or area of the party or gathering, and threatens public safety by permitting violations of law to go unpunished and unabated and increasing the risks of alcohol or drug related incidents causing personal injury and/or death; and
G. State law prohibiting conduct which contributes to the delinquency of minors does not address liability for allowing consumption of alcohol by persons who are eighteen (18) years of age or older, but under the legal drinking age, on premises under the control of the adult.

The notice of violation required under this section shall be personally served on the violator, or shall be sent by registered or certified United States mail to the property owner at the last known address listed on the most recent tax assessor’s records. In the case of service by registered mail or certified mail upon the property owner, a copy of the notice of violation shall be conspicuously posted at the property which is the subject of the notice of violation. The failure of any person to receive a notice of violation that was sent via registered or certified mail shall not affect the validity of any enforcement proceedings under this chapter.
D. The Police Department shall retain a declaration of the person making service, declaring the date, time and manner that service was made, and the date and place of posting if applicable. (Ord. 1031, 2018; Ord. 1030 § 2(13), 2018; Ord. 1007 § 1, 2015; Ord. 1002 §§ 2, 3, 2015)
19.01.060 Hearing Request and Procedure.¶
A. Any recipient of a notice of violation enforceable by administrative penalties under this chapter may request an appeal hearing to contest there was a violation, as specified in the notice of violation, or that they are responsible for said violation, by completing a “request for hearing form” and returning it to the City Clerk within fifteen (15) days from the date of the notice of violation. At the time of returning the request for hearing form to the City Clerk, the person or entity requesting the appeal hearing shall pay an appeal processing fee of one hundred fifty dollars ($150.00). Failure to pay the appeal processing fee, or make arrangements for the payment of the fee, may result in the hearing being postponed until the payment of such fee.
B. Any hearing conducted pursuant to this section shall be set for a date not less than fifteen (15) days nor more than sixty (60) days from the date that the request for hearing form is filed in accordance with this chapter, unless the matter is urgent or good cause exists for an extension of time, in which case the date for such hearing may be shortened, or extended, as warranted by the circumstances.
C. Any hearing provided under this section shall provide a full opportunity for the person or persons subject to a notice of violation to appear and contest the determination that a violation has occurred and/or that the violation continues to exist. If the appeal hearing involves a juvenile, such a hearing shall be private and confidential unless the juvenile’s parents/guardians specifically request that the hearing be public. The failure of any interested party to appear at a requested appeals hearing shall constitute a failure by such party to exhaust their administrative remedies, and a waiver of the same.
D. At the place and time set forth in the notice of hearing, the Hearing Officer shall conduct a hearing on the notice of violation. The Hearing Officer shall consider any written or oral evidence regarding the violation that may be presented by the violator, real property owner, any officer or agent of the Authority and/or City, and any other interested party.
E. After receiving all of the evidence presented, the public testimony portion of the hearing shall be closed. The Hearing Officer may then consider what action, or actions, if any, should be taken, including the imposition of any fines or penalties.
F. Within thirty (30) days following the conclusion of the hearing, the Hearing Officer shall issue written findings and make a determination regarding the existence of the violation. If the Hearing Officer finds by a preponderance of the evidence that a violation occurred, the Hearing Officer shall issue a written finding of those facts. The decision of the Hearing Officer shall be final.
G. The recipient or recipients of a notice of violation shall be served with a copy of the decision of the Hearing Officer, including an administrative order if one is issued, in the manner and method set forth by Larkspur Municipal Code Section 19.01.050(C). (Ord. 1062 § 14, 2022; Ord. 1031, 2018; Ord. 1030 § 2(13), 2018; Ord. 1007 § 1, 2015; Ord. 1002 §§ 2, 3, 2015)
19.01.070 Administrative Order.¶
If the Hearing Officer determines that a violation occurred as set forth by the notice of violation, the Hearing Officer shall issue an administrative order.
A. An administrative order may impose an administrative fine in the applicable amount set forth by Larkspur Municipal Code Section 19.01.040(D) per violation, or, in the alternative, a number of hours of community service as determined by the Hearing Officer. The denial of community service by the Hearing Officer may not be appealed under Government Code Section 53069.4.
B. Any appeal processing fee that is paid pursuant to Larkspur Municipal Code Section 19.01.060(A) shall be refunded to the payee if it is determined, after a hearing, that the person charged in the notice of violation was not responsible for the violation or that there was no violation as charged in said notice. (Ord. 1031, 2018; Ord. 1030 § 2(13), 2018; Ord. 1007 § 1, 2015; Ord. 1002 §§ 2, 3, 2015)
19.01.080 Collections and Lien Proceedings.¶
A. Any administrative fine or penalty in the amount set forth by the notice of violation, if an appeal is not requested in a timely manner, or as ordered by the Hearing Officer, if the matter is timely appealed, shall be paid to the City within thirty (30) days of service of the notice of violation or administrative order, unless an extension of time is requested by the violator and granted by the City.
B. Payment of a fine or penalty imposed pursuant to this chapter shall not excuse or permit any continuation or repeated occurrence of the violation that is the subject of the notice of violation.
C. Any administrative penalty or fines imposed within the notice of violation, if no timely appeal is made, or ordered by the Hearing Officer, if the matter is appealed, are a debt owed to the City. In addition to all other means of enforcement, any fines or penalties specified in the notice of violation, if no timely appeal is made, or specified in the administrative order of the Hearing Officer, may be enforced as a personal obligation of the violator.
D. If the violation is connected with real property and the violator is an owner of the real property, any fines or penalties may be enforced by imposition of a lien on the real property. The Police Department shall prepare and file with the City Clerk a report stating the amount due and owing. The City may record notice of this lien after a hearing before the City Council to consider any protest or objection to the lien. The City shall serve notice of the hearing upon the owner of record of the real property, based on the last equalized assessment roll or the supplemental roll, whichever is more current. The notice of hearing shall include the time, date, and place of the hearing and the amount of the lien to be imposed, and shall be served in the same manner as a summons in a civil action. If the owner of record cannot be found after a diligent search, the notice may be served by posting a copy thereof in a conspicuous place upon the property for a period of ten (10) days and publication thereof in a newspaper of general circulation published in Marin County, California. If the City Council determines that the lien should be imposed, the City may cause notice of the lien to be recorded with the County Recorder. Once recorded, the lien shall have the force and effect and priority of a judgment lien. Any fee imposed on the City by the County Recorder for costs of processing and recording the lien and the cost of providing notice to the property owner in the manner described herein may be recovered from the property owner in any foreclosure action to enforce the lien after recordation.
E. The remedies set forth in this section are not exclusive. The City may collect administrative penalties and fines by the use of the small claims court or by any other legal remedy. (Ord. 1031, 2018; Ord. 1030 § 2(13), 2018; Ord. 1007 § 1, 2015; Ord. 1002 §§ 2, 3, 2015)
19.01.090 Judicial Review.¶
Any person aggrieved by an administrative fine determination of the Hearing Officer may obtain review of that decision by filing a petition for review in the Marin County Superior Court, in accordance with Government Code Section 53069.4. (Ord. 1031, 2018; Ord. 1030 § 2(13), 2018; Ord. 1007 § 1, 2015; Ord. 1002 §§ 2, 3, 2015; Ord. 961 § 1 (part), 2008. Formerly 9.56.050)
19.01.100 Supplementary Enforcement Authority.¶
Nothing in this chapter shall prevent the City from initiating a civil or administrative action, or any other legal or equitable proceeding, to obtain compliance or to discourage noncompliance with the provisions of this code. The enforcement procedures described by this chapter are intended to be alternative methods of obtaining compliance and/or discouraging noncompliance with the provisions of this code and are expressly intended to be in addition to any other remedies provided by law. It is the intent of the City Council that the immunities prescribed in Penal Code Section 836.5 shall be applicable to personnel of the Police Department and of the City acting in the course and scope of employment pursuant to this chapter. (Ord. 1031, 2018; Ord. 1030 § 2(13), 2018; Ord. 1007 § 1, 2015; Ord. 1002 §§ 2, 3, 2015; Ord. 961 § 1 (part), 2008. Formerly 9.56.060)
