California Code, Health and Safety Code - HSC § 42454

Proceedings under Section 42453 shall conform to the requirements of Chapter 3 (commencing with Section 525), Title 7, Part 2 of the Code of Civil Procedure, except that it shall not be necessary to show lack of adequate remedy at law or to show irreparable damage or loss.

If, in any such proceeding, it shall be shown that an order for abatement has been made, that it has become final, and that its operation has not been stayed, it shall be sufficient proof to warrant the granting of a preliminary injunction.

If, in addition, it shall be shown that the respondent continues, or threatens to continue, to violate such order for abatement, it shall be sufficient proof to warrant the immediate granting of a temporary restraining order.
