Dane County, Wisconsin: Administration, Jail, Clerk of Court, Sheriff’s Office

A promise to close Dane County’s aging downtown jail is running into a hard capacity problem. As the county’s new jail facility nears completion, with a south tower addition expected by the end of the year, Sheriff Kalvin Barrett has said the old facility can’t actually close entirely — the new building simply won’t have enough beds to meet current population needs. That’s put the sheriff at odds with local justice reform advocates who say the county is reneging on a long-standing commitment. Dane County, home to Madison and more than 565,000 residents, is Wisconsin’s fastest-growing county, and its jail transition is playing out in real time. Here’s how the county’s administration, jail, courts, and sheriff’s office work.

Dane County Quick Facts

A Fast-Growing County With a New Executive

Dane County is governed by an elected County Executive working alongside the County Board of Supervisors, with other row officers — including the Sheriff, District Attorney, County Clerk, Treasurer, Register of Deeds, and Circuit Court Clerk — elected independently. Melissa Agard, a former state senator and Senate Democratic Leader, won a 2024 special election to succeed longtime Executive Joe Parisi after his resignation, then won a full term in April 2025 with 81% of the vote. She’s described fiscal responsibility and accountability in government spending as central priorities of her administration.

Dane County has grown into Wisconsin’s fastest-growing county, now spanning more than 60 cities, villages, and towns across roughly 1,200 square miles, anchored by Madison and its university communities.

A few structural basics:

• The County Executive and Board of Supervisors handle general administration from Madison, the county seat
• The Sheriff, District Attorney, County Clerk, and other row officers operate independently as elected constitutional positions
• Dane County’s Sheriff’s Office is the largest sworn law enforcement agency in the entire state of Wisconsin

The Sheriff’s Office: A Historic First and a Shift on Immigration Cooperation

Kalvin Barrett made history in 2021 as the first African American Sheriff in Dane County’s 188-year history, appointed by Governor Tony Evers before winning election in 2022 with more than 76% of the vote. He began his career as a deputy with the Dane County Sheriff’s Office, later taught criminal justice at Madison College, and returned to lead the agency he started his career in.

Since taking office, Barrett has expanded mental health response and re-entry programming and ended the department’s participation in deportation-related initiatives — a notable policy shift on immigration cooperation worth knowing if that’s relevant to your situation.

The Sheriff’s Office’s core responsibilities include:

• Operating Dane County’s jail system, including the transition between old and new facilities
• Patrol and investigations, with the office noting it’s the largest peace officer agency operating in the county
• Jail diversionary programs aimed at reducing recidivism
• Civil process and court security functions

The Jail Transition: Old Facility, New Construction

Dane County’s new jail facility is in the final stages of construction, with the south tower addition expected complete by the end of 2026. Sheriff Barrett has stated publicly that despite the new construction, the county won’t be able to fully close the old downtown jail facility as originally promised, because current jail population levels exceed what the new building alone can accommodate.

That announcement has drawn direct pushback from local advocates. James Morgan, co-founder of Madison Organizing in Strength, Equity and Solidarity (MOSES), described conditions inside the old jail from his own experience being held there decades earlier, calling it “very inhumane” and arguing the promise to close the facility is “being reneged upon.” Reverend Jerry Hancock of the Prison Ministry Project has framed the issue more broadly, arguing the county needs to address both incarceration capacity and the underlying social issues — like homelessness — that contribute to people ending up in jail in the first place. Sheriff Barrett has echoed a similar point, suggesting that addressing deeper societal failures would itself reduce incarceration over time.

For anyone dealing with the jail system during this transition:

• The Sheriff’s Office maintains a “Current Residents” inmate search tool through its official website
• Given the ongoing facility transition, confirm which building — old or new — currently holds the person you’re searching for
• Booking information typically takes a few hours to post after an arrest
• Bond can generally be posted through the Sheriff’s Office’s standard channels
• Visitation requires advance scheduling — confirm current procedures directly, since rules may shift as the new facility comes online

Courts in Dane County

Dane County Circuit Court handles the county’s civil and criminal caseload, with the Circuit Court Clerk managing case records and filings separately from the County Clerk, which handles a different set of county-level records and functions.

A few practical points:

• Case records can generally be checked online through Wisconsin’s statewide court system before an in-person visit
• Confirm whether you need the Circuit Court Clerk (case filings) or the County Clerk (other county records) — these are separate elected offices
• Self-help resources exist for people representing themselves, though staff cannot provide legal advice

Before You Visit

• Bring valid, government-issued photo ID to any county building, courthouse, or jail facility
• Confirm current jail facility status before visiting, given the active transition between the old downtown jail and the new construction
• Downtown Madison parking near county government buildings can be limited on weekdays
• Call the Sheriff’s Office directly for jail-specific questions rather than relying on older information during this transition period

Frequently Asked Questions

Q1. Is Dane County’s old jail actually closing?

Not entirely, according to Sheriff Kalvin Barrett, who has said current jail population levels make full closure impossible even after the new facility’s south tower addition is completed. This has drawn criticism from local advocacy groups who say the county is not following through on an earlier commitment — check current county announcements for the latest status on this evolving situation.

Q2. How do I find out if someone is in Dane County custody during the jail transition?

Use the Sheriff’s Office’s “Current Residents” search tool on their official website. Given the ongoing shift between the old and new facilities, confirm which building currently holds the person you’re looking for before visiting.

Q3. Does the Dane County Sheriff’s Office cooperate with federal immigration enforcement?

Sheriff Barrett has publicly stated the department ended its participation in deportation-related initiatives since taking office. Confirm current policy directly with the Sheriff’s Office if this is relevant to your specific situation, as policies can evolve.

Q4. What’s the difference between the Circuit Court Clerk and the County Clerk in Dane County?

The Circuit Court Clerk manages court case filings and records for Dane County Circuit Court. The County Clerk handles a separate set of county-level records and administrative functions. Confirm which office your specific need requires before visiting, since they’re distinct elected positions.
