The County Commissioners
They pay for the jail. The sheriff runs it.
- What they controlThe jail budget, the building itself, and the agreements that send prisoners to a regional jail or rent beds to other agencies. In Cuyahoga and Summit, the elected County Executive and County Council.
- What they don'tDay-to-day operations. The sheriff is separately elected and has charge of the county jail by state law (Ohio Rev. Code 341.01) — unless the county uses a regional jail run by a multicounty board.
- NoteThree-member Board of County Commissioners (Ted Mercer, Gregory A. Simmons, Wade H. Westfall).

Notes on the record
- Sheriff Dave Duchak is named on the county's own sheriff pages, matching the state association directory.
- The county publishes a 2025 Jail Needs Assessment on its own site with rated capacity, population and construction cost options.
- The in-custody roster is at miami.miamivalleyjails.org, headed 'Miami County Sheriff Dave Duchak'; it showed 142 people in the Miami County Jail when opened.
- Video visits: the county says off-site visit fees are set by the vendor ICSolutions and publishes no rates, so fees is 'no'.
- The municipal court publishes a bond schedule PDF (https://www.miamicountyohio.gov/wp-content/uploads/2025/01/Bond_Schedule_12-14.pdf) listing bond amounts by offence, but no guidance on how to post bond, so bond_info is 'no'.
- No county budget document was reachable: the auditor's site (miamicountyohioauditor.gov) refused our fetch, and the commissioners' documents page carries no budget.
- County seat recorded as Troy; county offices and courts are at 201 W. Main St., Troy, but no page we opened uses the words 'county seat'.
- What was tried and refused: http://www.miamicountysheriff.org (robots), https://www.miamicountyohioauditor.gov (fetch refused).
- The 2023 state inspection report gives the Miami County Jail a general housing capacity of 108 beds and a recommended capacity of 48, against the 42 rated beds in the county's own 2025 needs assessment.
- State inspection/oversight: Ohio's Bureau of Adult Detention inspected the Miami County Jail, 201 W. Main Street, Troy, on 15 August 2023 under the Minimum Standards for Jails in Ohio (Ohio Adm. Code 5120:1-8); the report, published on the state's site, says the jail 'is in compliance with 100% of the Essential Standards and at least 90% of the Important Standards meeting the requirements of a "Compliant Jail."'
These three offices decide who sits in a cell in Miami County and what it costs the people who live here. Nationally, almost 77% of the people who died in local jails in 2019 had not been convicted of anything, and suicide was the leading single cause of those deaths (Bureau of Justice Statistics, Mortality in Local Jails, 2000–2019).
How much is your sheriff — and your judge — costing you?
