Cal. Pub. Res. Code § 4423.1

(a) Burning under permit by a person on public or private lands, except within incorporated cities, may be suspended, restricted, or otherwise prohibited by proclamation. Any of the following public officers may issue a proclamation, which shall be applicable within their respective jurisdictions:
1. (1) The director or the director’s designee.
2. (2) Any county fire warden with the approval of the director.
3. (3) The federal officers directing activities within California of the United States Bureau of Land Management, the National Park Service, and the United States Forest Service.
(b) The proclamation may be issued when, in the judgment of the issuing public official, the menace of destruction by fire to life, improved property, or natural resources is, or is forecast to become, extreme due to critical fire weather, fire suppression forces being heavily committed to control fires already burning, acute dryness of the vegetation, or other factors that may cause the rapid spread of fire. A proclamation is effective on issuance or at a time specified therein and shall remain in effect until a proclamation removing the suspension, restriction, or prohibition is issued. The proclamation may be effective for a single day or longer. The proclamation shall declare the conditions that necessitate its issuance, designate the geographic area to which it applies, require that all or specified burning under permit be suspended, restricted, or prohibited until the conditions necessitating the proclamation abate, and identify the public official issuing the proclamation. The proclamation may be in the form of a verbal or audio recorded telephone message, a press release, or a posted order.
(c) The proclamation may be issued without complying with Chapter 3.5 (commencing with Section 11340) and Chapter 5 (commencing with Section 11500) of Part 1 of Division 3 of Title 2 of the Government Code.
