Government of Miami-Dade County
The government of Miami-Dade County is defined and authorized under the Constitution of Florida, Florida law, and the Home Rule Charter of Miami-Dade County.
Since its formation in 1957, the county has had a two-tier system of government. Under this system, Miami-Dade comprises a large unincorporated area and 34 incorporated areas or municipalities. Each municipality has its own government and provides such city-type services as police and zoning protection.
In 2018, a state constitutional amendment was passed that made the positions of county tax collector, property appraiser, supervisor of elections, and sheriff independent elected offices.
