History

The Chair of Los Angeles County serves a term of one year. Upon expiration of the term the duties of the Chair are rotated among the board members by order of seniority until 2015 when the board unanimously move the rotation by order of district. When Chair Pro Tem Sheila Kuehl announced her retirement at the end for her supervisorial term her term would expire before her Chair term would begin Janice Hahn was selected to be Chair and Lindsey Horvath was Chair Pro Tem allowing Horvath to become Chair the following year and Kathryn Barger was selected to be Chair Pro Tem to resume district rotation of the County Chair. The term for a supervisor typically lasts four years, any member will get to serve as chair at least once during the duration of their term. During his or her term of office, the chair has the option of calling himself or herself “mayor”, a practice that was started by Michael D. Antonovich during his tenure as a supervisor. This tradition was not continued by the current incumbents.{{Cite web |title=County Supervisors, Past to Present, Los Angeles County, California |url=http://www.laalmanac.com/government/gl02.php |access-date=2022-04-12 |website=www.laalmanac.com}}{{Cite web |date=2005-12-07 |title=Supervisor Antonovich becomes 'county mayor' |url=https://www.dailynews.com/general-news/20051207/supervisor-antonovich-becomes-county-mayor |access-date=2022-04-20 |website=Daily News |language=en-US}}
