California Code, Health and Safety Code - HSC § 11471

(a) The seizure is incident to an arrest or a search under a search warrant.

(b) The property subject to seizure has been the subject of a prior judgment in favor of the state in a criminal injunction or forfeiture proceeding based upon this division.

(c) There is probable cause to believe that the property is directly or indirectly dangerous to health or safety.

(d) There is probable cause to believe that the property was used or is intended to be used in violation of this division.

(e) Real property subject to forfeiture may not be seized, absent exigent circumstances, without notice to the interested parties and a hearing to determine that seizure is necessary to preserve the property pending the outcome of the proceedings. At the hearing, the prosecution shall bear the burden of establishing that probable cause exists for the forfeiture of the property and that seizure is necessary to preserve the property pending the outcome of the forfeiture proceedings. The court may issue seizure orders pursuant to this section if it finds that seizure is warranted or pendente lite orders pursuant to Section 11492 if it finds that the status quo or value of the property can be preserved without seizure.

(f) Where business records are seized in conjunction with the seizure of property subject to forfeiture, the seizing agency shall, upon request, provide copies of the records to the person, persons, or business entity from whom such records were seized.
