Locate Lassen County Jail Annex Inmates

Lassen County Jail Annex Overview

The Lassen County Jail Annex appears in the 2023 jail medical-services request for proposals as "Lassen County Jail-Annex" at 1415B Chestnut Street in Susanville. The RFP states that services to be provided to the Lassen County Jail would also be provided at the Jail Annex, and that references to jail services include the annex. That source treats the annex as part of the county jail medical and custody-service scope, not as a separate police jail with its own public lookup system.

The annex is operated by the Lassen County Sheriff's Office. The research did not locate a separate annex phone line, public roster, booking counter, public visiting schedule, or standalone annex records page. Use the Adult Detention Facility phone for current jail custody questions unless the county later publishes a distinct annex contact. The annex should be read as a county jail facility served by the same sheriff custody chain, records contact, court pathway, and outside locator fallbacks.

This distinction is important in Lassen County because several correctional systems exist in the same county. The Lassen County Jail Annex and the Adult Detention Facility are sheriff facilities for county inmates. High Desert State Prison is a CDCR prison for sentenced state prisoners. Federal Correctional Institution Herlong is a BOP prison for sentenced federal offenders. An annex search should stay within the county jail path unless the person has been transferred out of local custody.

Lassen County Annex Capacity

The annex has its own documented capacity details. The 2023 jail medical-services RFP describes the Jail Annex as 20 double-occupancy cells separated into two housing units. The BSCC rated-capacity list separately identifies the Lassen County Adult Jail Annex as a Type II facility with 40 beds. Those two statements align: 20 double-occupancy cells produce a 40-bed facility when all cells are used as described.

No separate official annex average daily population, demographic table, booking count, or current occupancy figure was located in the research sources. That gap should be preserved. The county jail system has broader population figures for the main jail and combined service needs, but the annex page should not invent an annex-only census. The most precise published fact is the annex bed and cell configuration.

Lassen County Annex Inmate Lookup

No separate official online roster was found for the Lassen County Jail Annex, and no official countywide online roster was verified for the Lassen County jail system. That means an annex inmate lookup starts the same way as a main jail lookup: call the Adult Detention Facility, then use the Sheriff's Office records contact if a document or records route is needed. The annex address can help identify the facility, but it does not change the official custody lookup chain.

1. Call the Lassen County Adult Detention Facility at (530) 251-5245 and ask whether the person is in county jail custody and whether the annex is involved.
2. Contact the Sheriff's Office records/contact page for records routing, the sheriff phone, and sheriff email.
3. Use the Lassen Superior Court Case Index and Calendar Portal page when the question concerns filed criminal charges, hearings, or a Register of Actions.
4. Search CDCR CIRIS if the person may have moved to state prison after sentencing.
5. Search the BOP inmate locator for federal custody, ICE ODLS for immigration detention, and California VINELink for custody notifications.

The lack of a verified county roster also means public search-field claims should stay narrow. Do not assume a last-name form, booking-number search, mugshot profile, bond field, or housing field exists online for the annex. Those details may exist in internal jail records or may be provided through allowed official channels, but they were not found as a public annex roster.

Lassen County Jail Annex Contact

The annex address comes from the 2023 medical RFP. The phone path is the jail phone because no separate official annex phone was located. The Sheriff's Office records/contact page remains the county-level contact path for records routing and gives the sheriff administration address, main sheriff phone, jail phone, dispatch phone, and sheriff email. For a current annex custody question, start with the jail phone rather than dispatch or the court.

Calling the court will not confirm whether a person is housed in the annex. The court can help with filed charges and hearing data after a case exists. The jail controls the current custody question, while the sheriff records/contact path is the official local route when a record request or contact detail is needed.

Lassen County Annex Housing Role

The annex is best understood as a custody-support facility within the Lassen County jail system. The RFP says the annex is made entirely of double-occupancy cells in two housing units. It also says medical services for the jail include the annex. Those facts support a practical description: the annex may be used for county adult inmates according to classification, housing, and bed-management needs, under the same sheriff operation as the main jail.

Official sources did not publish a public rule saying which inmates go to the annex, how long they remain there, or whether a particular class of inmates is always housed there. Avoid fixed claims such as "overflow only," "female only," "sentenced only," or "work release only" unless jail staff confirms it for a specific person. The documented point is narrower and more reliable: the annex is a Type II county jail annex with 40 rated beds and a shared jail service scope.

Annex

A related jail facility used as part of the county detention system, not a separate online roster system.

Type II facility

A California local detention facility category that can hold adults pending court and after sentence.

Classification

The jail process used to assign housing based on security, safety, health, separation, and custody needs.

Lassen County Annex Visiting

No official public family-visitation schedule specific to the Lassen County Jail Annex was located. No online scheduling system, video vendor, visit fee table, or annex visitor-entry rule was verified in the county pages reviewed. Because the annex is tied to the jail system, visitors should call the Adult Detention Facility before leaving for Susanville. Staff can confirm whether the person is housed at the annex, whether the person is eligible for a visit, and where the visitor should report.

The jail procedures manual does provide rules for official visits, which are different from regular family visits. Official visits can involve attorneys, physicians, behavioral health providers, clergy, alcohol or drug counselors, law-enforcement agents, and defense contractors. These visits generally occur in attorney/client rooms, do not count against an inmate's weekly regular visiting time, and have manual-listed official visiting hours of 0600-2400 subject to count and approval limits. Those rules should not be treated as a public family schedule.

Lassen County Annex Mail and Money

The county custody materials confirm that the jail system has policy topics for accounts, commissary, mail, telephones, personal property, inmate rules, and services. They do not publish a separate annex mail address format, deposit vendor, kiosk location, online money link, commissary fee, phone-rate schedule, or video-visit provider in the official sources reviewed. The safer approach is to verify the current rule with the jail before sending money, mail, or packages.

Money and communication rules can depend on custody status, housing, disciplinary status, medical status, and vendor contracts. For the annex, a verified public source did not provide enough detail to name vendors or fees. Any outside provider should be treated as unverified until confirmed by the Lassen County jail.

Lassen County Annex Booking Records

A person housed in the annex is still part of the Lassen County jail record path. The main jail receives people arrested by the Sheriff's Office, CHP, Susanville Police, Probation, CDCR, Cal-Fire, Herlong Security, FBI, and other agencies with arrest powers in the county. After booking, jail records and court records can diverge. A booking charge reflects arrest paperwork and intake. A court charge reflects what the District Attorney files in the Superior Court case.

California law provides useful boundaries. Government Code 7923.610 requires state and local law-enforcement agencies to make specified arrest information public unless disclosure would endanger safety or an investigation. Penal Code 13300 defines local summary criminal history information, including names, dates of birth, physical descriptions, arrest dates, arresting agencies, booking numbers, charges, and dispositions, while limiting access by requester and use. Those statutes support records access, but they do not create a public annex roster where one was not located.

If a person was booked very recently, the court portal may not yet show a case. If the person was sentenced to CDCR, the county jail may no longer be the current locator. If a federal or immigration matter is involved, BOP or ICE systems may be needed. A detainer, warrant, parole issue, probation hold, federal hold, or immigration issue can also affect release even when the local court case changes.

Lassen County Records Contact

The Sheriff's Office records/contact page is the official county contact source for sheriff address, sheriff phone, jail phone, dispatch phone, and sheriff email when a roster is not available.

The source view supports the annex lookup path because the annex does not have a separate verified public roster or records page in the sources reviewed.

Lassen County Annex Limits

The annex should not be described as an independent city jail, a state prison, or a federal detention center. It is a sheriff-operated county jail annex. It also should not be described as having a public online annex roster, public mugshot gallery, family visitation calendar, or money-deposit vendor unless a later official source verifies those details. Third-party jail pages exist on the web, but they were not used because the build source set is official county, court, state, and federal material.

The Lassen County Sheriff CA mobile app was found in the Apple and Google app stores. Store text describes reporting crimes, submitting tips, interactive features, and public-safety news, and says it is not for emergencies. The app-store text did not advertise an inmate roster, warrant search, or annex lookup, so it should not replace the jail phone or records contact.
