Cal. Health & Safety Code § 11361.5

(a) Records of any court of this state, any public or private agency that provides services upon referral under Section 1000.2 of the Penal Code, or of any state agency pertaining to the arrest or conviction of any person for a violation of Section 11357 or subdivision (b) of Section 11360, or pertaining to the arrest or conviction of any person under the age of 18 for a violation of any provision of this article except Section 11357.5, shall not be kept beyond two years from the date of the conviction, or from the date of the arrest if there was no conviction, except with respect to a violation of subdivision (d) of Section 11357, or any other violation by a person under the age of 18 occurring upon the grounds of, or within, any school providing instruction in kindergarten or any of grades 1 to 12, inclusive, during hours the school is open for classes or school-related programs, the records shall be retained until the offender attains the age of 18 years at which time the records shall be destroyed as provided in this section. A court or agency having custody of the records, including the statewide criminal databases, shall provide for the timely destruction of the records in accordance with subdivision (c), and those records shall also be purged from the statewide criminal databases. As used in this subdivision, “records pertaining to the arrest or conviction” shall include records of arrests resulting in the criminal proceeding and records relating to other offenses charged in the accusatory pleading, whether the defendant was acquitted or charges were dismissed. The two-year period beyond which records shall not be kept pursuant to this subdivision does not apply to any person who is, at the time at which this subdivision would otherwise require record destruction, incarcerated for an offense subject to this subdivision. For such persons, the two-year period shall commence from the date the person is released from custody. The requirements of this subdivision do not apply to records of any conviction occurring before January 1, 1976, or records of any arrest not followed by a conviction occurring before that date, or records of any arrest for an offense specified in subdivision (c) of Section 1192.7, or subdivision (c) of Section 667.5, of the Penal Code.
(b) This subdivision applies only to records of convictions and arrests not followed by conviction occurring before January 1, 1976, for any of the following offenses:
1. (1) A violation of Section 11357 or a statutory predecessor thereof.
2. (2) Unlawful possession of a device, contrivance, instrument, or paraphernalia used for unlawfully smoking cannabis, in violation of Section 11364, as it existed before January 1, 1976, or a statutory predecessor thereof.
3. (3) Unlawful visitation or presence in a room or place in which cannabis is being unlawfully smoked or used, in violation of Section 11365, as it existed before January 1, 1976, or a statutory predecessor thereof.
4. (4) Unlawfully using or being under the influence of cannabis, in violation of Section 11550, as it existed before January 1, 1976, or a statutory predecessor thereof.
  1. (A) A person subject to an arrest or conviction for those offenses may apply to the Department of Justice for destruction of records pertaining to the arrest or conviction if two or more years have elapsed since the date of the conviction, or since the date of the arrest if not followed by a conviction. The application shall be submitted upon a form supplied by the Department of Justice and shall be accompanied by a fee, which shall be established by the department in an amount which will defray the cost of administering this subdivision and costs incurred by the state under subdivision (c), but which shall not exceed thirty-seven dollars and fifty cents ($37.50). The application form may be made available at every local police or sheriff’s department and from the Department of Justice and may require that information which the department determines is necessary for purposes of identification.
  2. (B) The department may request, but not require, the applicant to include a self-administered fingerprint upon the application. If the department is unable to sufficiently identify the applicant for purposes of this subdivision without the fingerprint or without additional fingerprints, it shall so notify the applicant and shall request the applicant to submit any fingerprints which may be required to effect identification, including a complete set if necessary, or, alternatively, to abandon the application and request a refund of all or a portion of the fee submitted with the application, as provided in this section. If the applicant fails or refuses to submit fingerprints in accordance with the department’s request within a reasonable time which shall be established by the department, or if the applicant requests a refund of the fee, the department shall promptly mail a refund to the applicant at the address specified in the application or at any other address which may be specified by the applicant. However, if the department has notified the applicant that election to abandon the application will result in forfeiture of a specified amount which is a portion of the fee, the department may retain a portion of the fee which the department determines will defray the actual costs of processing the application, provided the amount of the portion retained shall not exceed ten dollars ($10).
  3. (C) Upon receipt of a sufficient application, the Department of Justice shall destroy records of the department, if any, pertaining to the arrest or conviction in the manner prescribed by subdivision (c) and shall notify the Federal Bureau of Investigation, the law enforcement agency which arrested the applicant, and, if the applicant was convicted, the probation department which investigated the applicant and the Department of Motor Vehicles, of the application.
(c) Destruction of records of arrest or conviction pursuant to subdivision (a) or (b) shall be accomplished by permanent obliteration of all entries or notations upon the records pertaining to the arrest or conviction, and the record shall be prepared again so that it appears that the arrest or conviction never occurred. However, where (1) the only entries upon the record pertain to the arrest or conviction and (2) the record can be destroyed without necessarily effecting the destruction of other records, then the document constituting the record shall be physically destroyed.
(d) Notwithstanding subdivision (a) or (b), written transcriptions of oral testimony in court proceedings and published judicial appellate reports are not subject to this section. Additionally, no records shall be destroyed pursuant to subdivision (a) if the defendant or a codefendant has filed a civil action against the peace officers or law enforcement jurisdiction which made the arrest or instituted the prosecution and if the agency which is the custodian of those records has received a certified copy of the complaint in the civil action, until the civil action has finally been resolved. Immediately following the final resolution of the civil action, records subject to subdivision (a) shall be destroyed pursuant to subdivision (c) if more than two years have elapsed from the date of the conviction or arrest without conviction.
