Cal. Code Regs. tit. 2, § 599.616
(a) Headquarters. Headquarters shall be established for each state officer and employee and shall be defined as the place where the officer or employee spends the largest portion of his/her regular workdays or working time, or the place to which he/she returns on completion of special assignments, or as the Department may define in special situations.
(2) Where the major portion of an employee's working time is spent within a specifically assigned or limited geographical area, such as a patrol area or beat where the same routes are traveled frequently and routinely on one-day trips, no per diem expenses shall be allowed at any location within 25 miles from any point in this assigned area as determined by the normal commute distance.
In order to ensure equity in special cases, agency heads may disregard this subsection and authorize individual claims based on subsection (1) of this regulation.

A primary dwelling shall be defined as the actual dwelling place of the employee that bears the most logical relationship to the employee's headquarters and shall be determined without regard to any other legal or mailing address.
