Lobbyists are defined as all persons, firms, entities, or corporations that are employed, designated, or retained by a principal, with or without compensation, or that contract with a third party for economic consideration to perform lobbying activities on behalf of a principal.

The Lobbyist Online Registration and Information System is used to register lobbyists and principals and provide searchable listings of those registered.

Lobbyist Registration is required within five days of being retained by a client or before engaging in any lobbying activity. Registration renewal is required by January 15th of each year. This online service allows lobbyists to register and pay the fee associated with lobbyist registration.

The COB prepares and publishes reports on a quarterly and an annual basis reflecting the lobbyist registrations filed in accordance the Miami-Dade County's Conflict of Interest and Code of Ethics ordinance. The reports may be viewed here Lobbyist Reports - Clerk of the Board - Miami-Dade County.
