The Ontario County Inmate Population
The Ontario County inmate population is reported through the local jail and state jail-population channels rather than a stand-alone county dashboard. The mapped local facility is Ontario County Jail, operated by the Ontario County Office of Sheriff. The jail holds people committed by Ontario County courts, including unsentenced detainees, local sentenced jail inmates, and any people who fit state reporting categories such as civil holds, federal holds, parole violators, state-ready prisoners, or boarded people. The county budget describes the jail as the place that provides care and custody for people committed by courts within Ontario County, along with transportation, transfers, court security, medical care, mental-health services, education, substance-abuse counseling, and inmate work details.
The count changes when arrests, court release orders, bail decisions, sentences, transfers, and holds change. A new arrest may begin with a local police department, the Sheriff, or State Police, but jail custody after court commitment is centralized at Ontario County Jail. If a person receives a state prison sentence, the record moves into New York State Department of Corrections and Community Supervision custody after transfer. If a federal or immigration case controls custody, the Bureau of Prisons or ICE locator becomes the better search path.
Ontario County Inmate Population Statistics
The strongest current figures come from the DCJS and State Commission of Correction monthly jail population report prepared June 1, 2026, plus Ontario County jail planning records. That state report listed Ontario County Jail with a May 2026 average daily census of 94 and an in-house population of 90. A county security and control systems purchasing document described the jail as a direct-supervision facility with current capacity for 291 inmates in seven housing pods and the Medical and Multi-Use Area.

Ontario County Inmate Population Trends
The 13-month state table shows a smaller Ontario County inmate population in May 2026 than in May 2025. The jail census fell from 116 to 94 over that May-to-May span, a 19 percent drop. The in-house count fell from 119 to 90, while the sentenced group moved from 22 to 24. The unsentenced category remained the largest part of the local jail count, which means many people in the Ontario County inmate population were still tied to pending court cases or other non-sentenced custody status.
| Month | Census | In House | Sentenced | Other Unsentenced | Note |
|---|---|---|---|---|---|
| May 2025 | 116 | 119 | 22 | 78 | State readies 9 |
| Jun 2025 | 117 | 121 | 27 | 74 | Highest census in the table |
| Aug 2025 | 98 | 98 | 32 | 59 | Boarded in 1 |
| Dec 2025 | 89 | 89 | 31 | 52 | Lower winter count |
| Jan 2026 | 84 | 87 | 32 | 52 | Lowest census in the table |
| May 2026 | 94 | 90 | 24 | 66 | Federal, civil, parole, and state-ready categories at zero |
Ontario County Jail Population Makeup
The state report provides legal-status categories, not a local race, age, or sex demographic table for Ontario County. For May 2026, the in-house population consisted of 24 sentenced people and 66 people listed as other unsentenced. The same monthly line showed zero civil detainees, zero federal detainees, zero technical parole violators, and zero state-ready prisoners. That does not mean those categories can never appear at the jail. It means they were not counted in those fields for that month.
Those categories matter for inmate lookup. A sentenced local jail inmate may still appear in local jail information channels. A state-ready prisoner is someone sentenced to state prison but still awaiting DOCCS transfer. Once transfer occurs, the public should switch to the New York incarcerated individual lookup. A federal or immigration hold can point away from the county jail and toward the BOP inmate locator or ICE Online Detainee Locator System.
- Other unsentenced
- A person held before final sentence, often because a case, release order, hold, or appearance is still pending.
- State ready
- A person sentenced to state prison but not yet transferred to DOCCS custody.
- Boarded out
- A person counted for Ontario County but housed outside the jail under a boarding arrangement.
- Detainer
- A notice or custody interest from another agency that may affect release or transfer.
Ontario County Jail Capacity
Ontario County Jail is not described in the inspected official sources as being under a current overcrowding order or consent decree. Using the sourced capacity of 291 and the May 2026 in-house population of 90, the jail was operating well below capacity for that month. That is an arithmetic comparison drawn from official figures, not a separate official utilization rate. The facility history still matters because the current building replaced older jail capacity concerns and was designed with a larger direct-supervision model.
A county purchasing document says the jail was constructed in 2002 and 2003 in the Town of Hopewell. It lists seven housing pods, medical and multi-use areas, intake, visitation, kitchen, laundry, storage, and administration support areas. The same document says the core facilities were designed for possible expansion to 512 through added housing pods. The older jail history record says the 2002 project was presented as a 276-bed plan with a $28.75 million proposal.
Ontario County Inmate Population Laws
New York law shapes what the public can see, how the jail is regulated, and why some records do not appear online. FOIL is broad, but it does not override every law-enforcement, safety, privacy, youthful-offender, medical, mental-health, or sealing limit. Court records also follow a different route from jail records. In practice, jail custody information, court case information, and state prison information often sit in three separate systems.
Key laws and agencies:
Public Officers Law section 87 sets New York FOIL access rules, exemptions, subject-matter lists, and ordinary copy-fee rules.
Correction Law section 45 gives the State Commission of Correction inspection and minimum-standard authority over local correctional facilities.
Correction Law section 47 covers Medical Review Board duties and immediate reporting of deaths in custody.
Criminal Procedure Law section 160.50 explains sealing after a case ends in favor of the accused, including records tied to photographs and fingerprints.
Ontario County State Prison Search
No DOCCS state prison was mapped as physically located in Ontario County in the official sources reviewed. That does not end the state prison issue. A person sentenced in an Ontario County criminal case may move from Ontario County Jail into DOCCS custody. At that point, the county jail line may no longer be the best source for housing location or release dates, and the state locator becomes the main public search tool.
DOCCS records are built around state custody fields such as DIN, custody status, housing or releasing facility, admission type, county of commitment, crime information, sentence ranges, parole dates, conditional release dates, and maximum expiration dates. DOCCS also warns that it is not responsible for people held in county correctional facilities or local police lockups. Fresh arrests should still be checked through Ontario County channels.
Search Ontario County Inmate Records
The county’s official Incarcerated Individual Locator page sends the public to the New York incarcerated lookup and notes that users can create an account for release notification and other information. Ontario County did not provide a separate county-only booking list with clickable local jail profiles in the static sources reviewed. That makes the jail phone line, VINE, and FOIL path important fallback channels when the statewide lookup does not answer a local custody question.
The practical search chain starts online and then moves to direct local channels. Very recent bookings may involve intake, classification, a first court appearance, or record timing that does not produce a clean online result. The jail automated line at 585-396-1800 covers criminal charges, bond information, court information, visitation times, projected release dates, and phone account funding.
- Open the Ontario County incarcerated individual page or go straight to the New York incarcerated lookup.
- Search by DIN or NYSID if that exact identifier is known.
- For a name search, start with last name and add first name or birth year only when needed.
- If the person was just arrested, call Ontario County Jail because the phone channel may be more useful than a statewide result.
- If the person was sentenced to state prison, search DOCCS by DIN or name instead of treating the jail as the current custodian.
- If federal or immigration custody is possible, use the BOP or ICE locator and check court records for the case path.
Ontario County Current Inmate Lookup
The New York lookup accepts identifier and name searches. The official DOCCS instructions say computerized lookup information is generally available all day, with a short nightly maintenance outage and a longer Saturday night server maintenance window. Ontario County’s local page uses the same state path for public incarcerated-individual searches, but users should reconcile that with DOCCS language that county jail detainees are not DOCCS responsibility. The local jail line remains the best fallback for a fresh Ontario County booking.
The New York incarcerated lookup interface is the search screen Ontario County points readers toward for custody lookup.
The screen supports statewide custody searches, but a local phone call can still be needed when a new Ontario County jail booking is not easy to locate online.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| DIN | Text | Optional unless using DIN-only search | Most direct state-prison identifier, with a format such as 98-A-0004. |
| NYSID | Text | Optional if known | Intended for criminal justice agencies and not displayed by the lookup. |
| Last Name | Text | Needed for name search | Partial or full last name works without birth year; exact last name is used with birth year. |
| First Name | Text | Optional | Used for initial positioning, not a guarantee that only that first name appears. |
| Birth Year | Number | Optional | With last name, includes people born during or after that year. |
Ontario County Records Fallbacks
Past and released inmate records may require more than one channel. The county jail line covers current custody details such as charges, bond, court information, release projections, and phone funding. The Sheriff Records page says reports are routed through the Records Office and, when needed, to the County Records Access Officer for FOIL review. Ontario County’s FOIL page uses NextRequest and explains that public records can be requested from the county, subject to exemptions.
The Ontario County Sheriff Records page is the local record-routing source for reports and FOIL handling.
That route matters when a booking record, incident report, or jail-related public record is not exposed through the inmate lookup.
Ontario County Inmate Record Fields
Ontario County’s public materials split inmate record facts across the state lookup, the jail phone line, the visitation process, and FOIL. A caller may be directed to criminal charges, bond information, court information, projected release dates, and phone account funding. Bail payment instructions show that an inmate criminal history number, date of birth, bail amount, court, judge, and pay location code can matter for payment. Not all of those fields appear in a single online profile.
| Field | What It Shows |
|---|---|
| Name | Used for mail and name lookup through the state search path. |
| Criminal history number | Needed for bail payment and obtained by calling the jail. |
| Charges | Available as a jail automated-line topic, though court charges may later change. |
| Bond or bail | Amount and payment details may be available through the jail information line. |
| Court and judge | Needed for bail processing and for tracing the court case after arrest. |
| Projected release | Listed by the county FAQ as an automated-line topic. |
| Mugshot | No official county public roster profile with booking photos was found in the static sources reviewed. |
Ontario County Jail vs Prison
A county jail search is not the same as a state prison search. Ontario County Jail handles local court commitments, pretrial detention, local sentences, and short-term custody stages. DOCCS handles sentenced state-prison custody after transfer. BOP and ICE each have separate systems. This difference is the reason a person can seem to disappear from one search tool while appearing in another.
| Custody path | Who it covers | Where to look |
|---|---|---|
| County jail | Fresh arrests, pretrial detainees, local sentenced jail inmates | Ontario County locator page, jail line, FOIL/Records |
| State prison | People sentenced and transferred to DOCCS | New York incarcerated lookup and DOCCS data definitions |
| Federal custody | Federal inmates from 1982 to present | BOP inmate locator by number or name |
| Immigration detention | People in ICE custody | ICE ODLS by A-Number/country of birth or biographic data |
Ontario County Detention Facilities
The facility map resolves to one local detention facility. No separate Ontario County work-release center, annex, state prison, BOP facility, or ICE detention facility was found in the official sources reviewed. Local police departments may process arrests, but the long-term public custody path for Ontario County court commitments points to the county jail and then to state or federal systems if custody changes.
- Ontario County Jail holds people committed by Ontario County courts, including pretrial detainees, local sentenced inmates, and any reported hold or transfer category.
