The Legislature, and in six counties a county board

The state pays for the jail. The elected sheriff runs it.

What they controlThe appropriation. Massachusetts abolished county government in eight of the fourteen counties — Berkshire, Essex, Franklin, Hampden, Hampshire, Middlesex, Suffolk and Worcester — and their sheriffs and houses of correction are managed by the state Executive Office of Public Safety and funded by the Legislature. Six counties still function as governmental units: Barnstable (as Cape Cod Regional Government), Bristol, Dukes, Nantucket, Norfolk and Plymouth.
What they don'tDay-to-day operations. The sheriff is separately elected to a six-year term (MGL ch. 37 § 1) and has custody and control of the jail, the prisoners and the staff (MGL ch. 126 § 16). The Department of Public Health inspects the facilities and publishes the reports.
NoteMassachusetts abolished this county's government. There is no county board. The Legislature appropriates the jail's money and the state Executive Office of Public Safety manages the office.

Notes on the record

Massachusetts abolished this county's government. The sheriff and the house of correction are managed by the state Executive Office of Public Safety and funded by the Legislature; there is no county board.
The Sheriff's Office publishes its policy on the prevention of sexual abuse together with aggregated Prison Rape Elimination Act data for 2022 and 2023 in a searchable document centre. Publishing the incident data itself, rather than only an audit, is rare.
Several pages the menu names — posting bail, canteen and property, telephones — could not be read, and those checks are recorded as not scored rather than as no.

These three offices decide who sits in a cell in Middlesex 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?

Your VOTE is POWERFUL.

The sheriff who runs this jail is elected, to a six-year term. In eight counties there is no county board to elect at all.
