# 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.

## Overview

Of the county's 2,751,796 total residents (as of 2017), approximately 44% live in unincorporated areas, the majority of which are heavily urbanized. These residents are part of the Unincorporated Municipal Services Area (UMSA). For these residents, the County fills the role of both lower- and upper-tier government, the County Commission acting as their lower-tier municipal representative body. Residents within UMSA pay an UMSA tax, equivalent to a city tax, which is used to provide County residents with equivalent city services (police, fire, zoning, water and sewer, etc.). Residents of incorporated areas do not pay UMSA tax.

## Organization

An Executive Mayor and the Miami-Dade Board of County Commissioners (BCC) govern the County. The County's main administrative offices are located in the Stephen P. Clark Center (SPCC) at 111 NW 1ST Street in downtown Miami.

### Board of County Commissioners

The Miami-Dade Board of County Commissioners is the governing body of unincorporated Miami-Dade County and has broad regional powers to establish policies for Miami-Dade County services. The government provides major metropolitan services countywide and city-type services for residents of unincorporated areas.
One County Commissioner is elected from each of Miami-Dade County's 13 districts to serve a four-year term. Residents choose only from among candidates running in the district in which they live. Commissioners are chosen in non-partisan, single-district elections and can serve two four-year staggered terms, with elections scheduled every two years. The Commissioners elect a Chairperson, and the Chairperson appoints the members, chairperson and vice chairperson of all standing committees.
In November 2012, the Miami-Dade County Term Limit Amendment was approved, modifying the County charter to establish term limits of two consecutive four-year terms.
