Martin County Florida Government: Structure, Services, and Resources

Martin County occupies the southeastern Atlantic coast of Florida, covering approximately 556 square miles with a county seat at Stuart. This page covers the administrative structure of Martin County government, the principal service delivery mechanisms, and the regulatory and procedural frameworks that govern residents, businesses, and property owners within county jurisdiction. Understanding how Martin County's governing bodies relate to Florida's broader state government framework is essential for residents, contractors, and professionals operating in this area.

Definition and scope

Martin County is one of Florida's 67 counties, established under Article VIII of the Florida Constitution and governed through a county commission model. The Board of County Commissioners (BOCC) serves as the primary legislative and executive body at the county level, composed of 5 commissioners elected from single-member districts to staggered 4-year terms.

Martin County operates as a non-charter county under Florida Statute §125, which defines the powers, duties, and limitations of county government in non-charter jurisdictions. This distinguishes Martin County from charter counties such as Miami-Dade or Broward, which have adopted home-rule charters granting broader self-governance authority. In a non-charter county, state statute governs the organizational structure, limiting flexibility in how functions are allocated between elected and appointed officials.

Scope boundary: This page addresses only the governmental structure and services of Martin County, Florida. Federal programs administered locally, tribal jurisdictions, and municipal governments within Martin County — including the City of Stuart, the Town of Jupiter Island, and the Town of Sewall's Point — fall outside the scope of county governance as described here. Florida state agency operations within the county, including Florida Department of Transportation district offices and Florida Department of Health county health departments, operate under state authority rather than county authority, even when physically co-located with county facilities.

How it works

Martin County government functions through two parallel tracks: the BOCC, which oversees county departments and sets policy, and the constitutionally mandated elected officers (constitutional officers) who exercise independent authority over defined functions.

Elected Constitutional Officers in Martin County:

  1. Clerk of the Circuit Court and Comptroller — Manages court records, official public records, financial reporting, and board minutes under Florida Statute §28.
  2. Property Appraiser — Annually assesses all real and personal property within the county for tax roll purposes under Florida Statute §192.
  3. Sheriff — Provides law enforcement, jail operations, and court security; the largest single departmental expenditure in most Florida counties.
  4. Supervisor of Elections — Administers voter registration, candidate qualifying, and election logistics under Chapter 97 of Florida Statutes.
  5. Tax Collector — Collects property taxes, motor vehicle registration fees, and other state and local revenues under Florida Statute §197.

These five offices receive independent budget allocations and are not subordinate to the BOCC in their core statutory functions, though the BOCC controls funding appropriations. The Florida county government structure framework applies uniformly across all 67 counties for constitutional officers.

The BOCC-controlled departments handle planning and zoning, parks and recreation, public works, emergency management, utilities, and community development. The county administrator, appointed by the BOCC, coordinates day-to-day operations across these departments.

Martin County participates in the South Florida Water Management District, one of Florida's 5 regional water management bodies (Florida Water Management Districts), which exercises independent authority over water use permitting, flood control, and environmental resource management within the county's boundaries.

Common scenarios

Residents and professionals encounter Martin County government across a defined set of recurring situations:

Decision boundaries

Determining which level of government handles a specific issue in Martin County requires distinguishing between three categories:

County vs. Municipal: The BOCC and county departments have jurisdiction only in unincorporated Martin County. The City of Stuart and the two incorporated towns maintain separate planning, code enforcement, and licensing functions. A contractor working in both Stuart and unincorporated Martin County must hold separate permits and comply with separate codes for each jurisdiction. The Florida municipal government framework governs these incorporated areas.

County vs. State: The Florida Department of Business and Professional Regulation licenses contractors, real estate agents, and health professionals statewide — a county license does not substitute. Similarly, environmental permits for activities affecting state waters require Florida Department of Environmental Protection review independent of any county approval.

County vs. Special District: Martin County contains special districts for fire rescue, drainage, and mosquito control that hold independent taxing authority and governing boards. The Martin County Mosquito Control District, for example, operates under Chapter 388, Florida Statutes, with its own elected board, budget, and millage levy — not under BOCC authority.

Adjacent counties including St. Lucie County to the north and Palm Beach County to the south maintain entirely separate governmental structures, and inter-county services such as regional planning fall under the Florida Regional Planning Councils framework.
