The Rock County WI Jail is a medium-security detention center located at 200 E US Hwy 14 Janesville, WI which is operated locally by the Rock County Sheriff's Office and holds inmates awaiting trial or sentencing or both. Most of the sentenced inmates are here for less than two years. Rock County accepts inmates from surrounding towns, municipalities, the US Marshal's Service and the Janesville Police Department who do not have their own long-term lock-up.

Rock County Jail is responsible for the safety and security of sentenced and un-sentenced male and female inmates. Operate in accordance with Wisconsin State Statutes, Department of Corrections Administrative Code, and the United States Constitution.

Commissary - Tuesday and Friday and must be ordered the proceeding day. Funds must be available prior to order any items.

Indigent Inmates - Inmates who have no money will be provided soap, toothbrush and toothpaste, comb, three pieces of writing paper and three envelopes, weekly. Any debt incurred by indigent inmates is subject to Income Tax Intercept and/or collection agency. Inmates found to be indigent will receive a weekly hygiene packet.

Inmate Health Services
The Rock County Jail has a twenty-four hour a day nursing staff on-site and doctors who are available to review the inmate's medical needs three times a week. It is the policy of the Rock County Jail to charge inmates a medical co-pay service fee for medical, dental, prescription and non-prescription services while they are incarcerated in the Jail.

Medical Co-Pay Fee Schedule

  • Dentist $10.00
  • Nurse Visit $7.00
  • Prescription Filled $5.00 Each
  • Over the Counter Medication $5.00 Each

* Reasonable follow-up visits and referrals to the Doctor will not be charged.

  • No inmate will be denied medical care due to the inability to pay or insufficient funds in the inmate's account.
  • Fees will be collected only for services requested by an inmate or if an inmate needs medical care due to disruptive actions.
  • All fees will be immediately deducted from the inmate's account. If there are insufficient funds in the account the fees will be charged and the account will show a balance due.
  • Any money received by the inmate, except for bond money, will first be used to satisfy the inmate's debt with the Rock County Jail before any money can be used for commissary.
  • Sentenced inmates that have Huber/Work Release privileges are required to see the Jail medical staff if their inmate account has a zero or negative balance.

All medication is generally ordered by the Jail medical staff. However, medication from another physician may be accepted into the Jail only if it is delivered to the Jail in its original prescription bottle and is for the intended inmate. Medications will be reviewed, verified and approved by medical staff prior to being dispensed. The Jail medical staff will determine if the medication is needed, appropriate, and required.
