The Los Angeles County Board of Supervisors represents nearly 10 million people.

County governments provide public safety services, make land-use decisions, administer welfare programs and maintain roads. There are more than 3,000 county governments in the United States with duties that vary by state, according to the National Association of Counties. Members of the Board of Supervisors get letters regarding upcoming votes on policy matters, requests for help with county services and invitations to events. When you write a letter to the Board of Supervisors on an issue on the board’s agenda, your letter may become part of the public record for that meeting. (See Reference 1)

Visit the "Find a County" web page on the website of the National Association of Counties to get the address for your Board of Supervisors.

Click on your state on the map or type the name of your county in the search box and click on "Search for Matches." Click on the name of your county. A page with a list of county officials for the county, a county address and a link to the county's website will appear.

Address the letter by typing the name of the county followed by "Board of Supervisors" on the first line of the address.

Type the mailing address on the second line and the city, state and ZIP code on the following line.

Type either "Dear Members of the Board" or "Dear Members of the Board of Supervisors" as the salutation of your letter.

Things Needed

  • ['Stationery', 'Computer/printer']


  • Check the web page for your Board of Supervisors. Local officials may prefer to have letters addressed to the Clerk of the Board of Supervisors. In these cases, the clerk will distribute copies of correspondence to all supervisors.

    The supervisor or a staff person may want to call you for more information, so be sure to include your phone number.

    Send requests for county proclamations to honor an individual or organization well in advance of the date of the event.

    Address correspondence to the supervisor for your district if it involves a specific problem you are having with county services. Elected officials traditionally deal with these constituent service issues within their own districts.
