In most of the country, the sheriff runs the jail and the police chief runs the streets, and neither one answers to a mayor. Duval County, Florida throws all of that out. It merged with the City of Jacksonville back in 1968, and the result is a single agency — the Jacksonville Sheriff’s Office — that functions as both municipal police department and county jail operator, all under one elected sheriff who’s technically a city-county constitutional officer rolled into one. For the roughly 1 million people living in what’s officially Duval County but functions day-to-day as the City of Jacksonville, that consolidation shapes almost everything about how local government works.

One Government, Not Two
Jacksonville’s 1968 consolidation vote merged nearly all city and county functions into a single government, a rarer move than you’d expect given how often the idea gets floated elsewhere and abandoned. The result: the Mayor of Jacksonville is legally the chief administrator of Duval County itself, not just the city. Donna Deegan, elected in 2023 as the city’s first woman mayor and first Democrat in the role in years, oversees county-level administrative functions that in most states would sit with a separate county judge or commission.
The City Council, made up of 19 members representing a mix of district and at-large seats, functions as the legislative body for both city and county matters simultaneously. A handful of Duval County functions remain separate constitutional offices outside the mayor’s direct control — the Sheriff, Property Appraiser, Tax Collector, and Supervisor of Elections chief among them, each independently elected by county voters.
What that means for residents:
- There’s no separate “Duval County government” building distinct from Jacksonville’s city hall — they’re the same institution
- Certain older, smaller municipalities within Duval County (Atlantic Beach, Neptune Beach, Jacksonville Beach, Baldwin) opted out of consolidation and retain their own city governments and police departments
- Property records, permits, and most administrative services route through city departments rather than a separate county bureaucracy
The Sheriff’s Office Does Double Duty
T.K. Waters has led the Jacksonville Sheriff’s Office since winning a 2022 special election, following the resignation of his predecessor after it emerged he’d moved out of the county. Waters, a 30-year JSO veteran, ran unopposed for his first full term months later and now oversees an agency with a genuinely unusual scope for American law enforcement:
- Full municipal police services across Jacksonville — patrol, investigations, traffic enforcement — the work a city police department would normally handle
- Operation of the Duval County Jail and Pretrial Detention Facility, a function typically split off to a separate county sheriff or corrections department elsewhere
- Court security for the Fourth Judicial Circuit
- Civil process service — warrants, evictions, foreclosures
Because JSO absorbed what would elsewhere be two separate agencies, its budget and staffing dwarf what you’d see from a standalone city police department serving a similar population. If you’re comparing Duval County to a non-consolidated county, remember there’s no separate municipal police force to check — JSO is it, except within the handful of beach communities that stayed independent.
Locating Someone in Custody
- JSO runs an online inmate search covering the Duval County jail system, generally searchable by name or booking number
- Because JSO also serves the beach communities under contract in some cases, confirm whether an arrest happened inside JSO’s jurisdiction before assuming Duval’s jail is the right facility to check
- New bookings typically take a few hours to appear in the online system
- Bond can usually be posted directly at the jail or through JSO’s approved online payment system
- Visitation requires advance registration and photo ID — call ahead, since the consolidated agency’s scale means procedures can differ somewhat by facility
Courts and the Clerk
Duval County sits within Florida’s Fourth Judicial Circuit, which also covers Nassau and Clay counties. The Duval County Clerk of Courts, a separately elected constitutional officer independent of both the Mayor and Sheriff, maintains court records, processes filings, and handles a range of financial functions typical of Florida’s clerk offices — a structure similar to what you’d find in Miami-Dade or Hillsborough County.
Practical notes:
- Case lookup is available online through the Clerk’s official records portal before an in-person visit is needed
- Traffic citations, small claims, and larger civil or criminal matters route through different divisions — confirm which applies to your situation
- Marriage licenses and official records recording (deeds, liens) also go through the Clerk’s office, separate from anything JSO handles
- Self-help resources exist for people without an attorney, though staff can’t offer legal advice
Before You Visit
- Bring photo ID to any city-county building, courthouse, or the jail
- Confirm whether your matter is inside JSO’s jurisdiction or one of the independent beach cities, since Atlantic Beach, Neptune Beach, and Jacksonville Beach run their own police departments
- Downtown Jacksonville parking near the courthouse and jail can be tight on weekday mornings
- Call JSO directly for jail-specific questions rather than assuming a separate “county sheriff” office exists somewhere else — there isn’t one
Common Questions
Q1. Is the Jacksonville Sheriff’s Office the same thing as Jacksonville Police?
Yes — there’s no separate police department for the consolidated city-county. JSO handles both the police function you’d expect from a city department and the jail operations you’d expect from a county sheriff, all under one agency.
Q2. Do all of Duval County’s cities fall under the Sheriff’s jurisdiction?
No. A handful of smaller municipalities — Atlantic Beach, Neptune Beach, Jacksonville Beach, and Baldwin — opted out of the 1968 consolidation and maintain independent city governments with their own police departments. Confirm which jurisdiction covers your specific location before contacting JSO.
Q3. How do I find out if someone is in the Duval County Jail?
Use JSO’s online inmate search, searchable by name or booking number. Allow a few hours after a recent arrest for the record to post, and confirm the arrest actually falls under JSO’s jurisdiction rather than one of the independent beach cities.
Q4. Why does the Mayor of Jacksonville handle county-level matters?
Because of the 1968 consolidation, the Mayor of Jacksonville is legally the chief administrator for all of Duval County, not just the city. There’s no separate county executive or commission — city and county government are functionally the same institution here.
