Kendall County Jail — Yorkville, Illinois

Kendall County Corrections is the Sheriff-operated adult jail at 1102 Cornell Lane, Yorkville, IL 60560. Call 630-553-7500. The May 8, 2025 state inspection records 107 male beds, zero female beds and zero juvenile beds. The building also held U.S. Marshals and other Illinois-county detainees on inspection day; those are custody classes inside this jail, not proof of a BOP or ICE facility.

The official search accepts name, subject number, booking number, in-custody status and booking-date ranges. A result can show a photograph, charges, bond amount, release date and arresting agency. Search name variants and widen the booking dates. Then call 630-553-7500 to confirm the identifier, current housing authority, case number, court, holds and any pending transfer or release. A court docket or VINE alert answers a different question and does not prove the person is still in this building.

1. Record the exact legal name and date of birth.
2. Save the subject and booking numbers separately.
3. If staff says IDOC, BOP, ICE, youth or another county, use that operator’s locator and rules.

Use 911 for an immediate emergency. Do not ask a provider to override a jail eligibility or movement decision.

All family and friend visits are by video and require advance scheduling and approval. Remote visits are offered daily, as scheduling permits, during 8 a.m.–12 p.m., 1–5 p.m. and 7–11 p.m.; they may not be back-to-back. Free lobby visits are offered Monday–Thursday and Sunday during 10 a.m.–12 p.m., 2–4:30 p.m. and 7–9 p.m., up to two per week, 20 minutes, with two registered adult visitors. The jail promises at least one visit per week except a disciplinary penalty. Lockdown, court, health movement, misconduct or emergency can delay or end a visit; the detained person may refuse.

Sources: Kendall County video visitation rules · 2025 Illinois jail inspection: Kendall County

Visitors must be 18 or older unless accompanied by a parent or guardian, who must stay in the lobby booth or remain physically present during a remote session. A restraining or no-contact order blocks a contrary visit. Video is recorded and monitored except attorney video. The county prohibits nudity, sexual conduct, weapons, drugs, alcohol, gang graphics, unlawful activity and recording or photographing the session. Its page expressly includes exposed breastfeeding in its nudity rule; a nursing visitor should ask the jail in advance about a lawful private-feeding or accommodation option. The page does not publish accepted photo ID, proof of guardianship, dress code, belongings, infant supplies, service-animal procedure, language help or accessibility request timing. Call 630-553-7500 before booking.

The 2025 state inspection says Securus supplies video, phone, messaging and tablets. The county’s current visit page instead says billing issues go to NCIC. Do not merge the brands or fund both. First select Kendall County and the person in the live portal; if the facility/person is absent or the branding conflicts, call the jail. For NCIC billing call 800-943-2189. For Securus mobile support call 972-734-1111; for landline/international support call 800-844-6591. No local price, cancellation, no-show or failed-session credit rule was found.

1. Save the confirmation, scheduled time, participant name and receipt.
2. Test camera, microphone, speakers, permissions and connection; sign in early.
3. Capture the exact error and whether the portal charged the account.
4. Ask the provider about account, device, payment or refund status.
5. Ask the jail about lockdown, court, medical movement, discipline or eligibility.

Do not assume a provider refund when the jail cancels; ask for the written rule and a ticket number.

The 2025 inspection establishes Securus phone service, but the county does not publish Kendall-specific rates, call hours, call-length limits, number-registration rules, blocked-number removal, refunds, balance transfer or privileged legal-call procedure. Securus describes AdvanceConnect, Securus Debit and Direct Bill; availability differs by facility. Use the option actually shown for Kendall and review the live rate disclosure before payment. The detained person initiates ordinary calls; the jail cannot connect an incoming social call. Account support is 972-734-1111 (mobile) or 800-844-6591 (landline/international).

The inspection says Securus supplies messaging and tablets. That does not establish that every person, housing unit or product is eligible. Confirm the person in the live account, review the displayed price and delivery rules, and never use social messaging for legal strategy, a health emergency or an urgent release instruction. Save a receipt and message status. Ask Securus about account or payment failure and the jail about eligibility, confiscation, discipline or movement.

Send nonprivileged mail by USPS to:
Kendall County Corrections
1102 Cornell Lane
Yorkville, IL 60560
C/O [first and last name]
[inmate ID number]

Use a valid return address. Incoming mail is opened and inspected; gummed areas, stickers, tape and metal are removed. Postage-due mail, unknown recipients and prohibited contents are rejected or returned. The page says mail without a return address is forwarded to an address provided at intake—an unusual source-specific statement; do not rely on it as a delivery route. Confirm the ID and current housing before sending.

Sources: Kendall County inmate mail procedures

Incoming legal mail must be stamped Legal Mail or it may be processed as nonprivileged. It is opened in the recipient’s presence. Outgoing legal mail may be sealed only for the listed qualifying destinations: registered attorneys, courts, legislators, correctional officials, John Howard Association, direct legal-representation organizations and Mutual Ground for PREA. The page does not publish a separate legal-mail address, electronic legal-mail route, attorney-call registration or rejection appeal. Counsel should confirm the recipient ID and privileged-channel requirements with the jail before sending.

Sources: Kendall County inmate mail procedures · Kendall Public Defender

The mail page authorizes only listed newspapers sent prepaid directly from the publisher, with no more than two in possession. It currently names the Wall Street Journal, Washington Post and New York Times. It prohibits magazines and clippings, photocopies of books, internet mail showing screen names or email addresses, stamps, stationery, laminated items, envelopes, calling cards, metal, glitter, crayon, lipstick, perfume, gang/crime material, nudity and provocative photographs. It does not publish a current personal-photo quantity, family package program, book-vendor route or appeal for a rejected publication. Call before ordering; a retailer’s willingness to ship is not jail approval.

The Sheriff FAQ links JailATM for commissary money and says a deposit becomes the detained person’s property, may be reduced by a negative balance and is not returned to the depositor. The 2025 inspection identifies Stellar Services as the commissary vendor; that does not necessarily conflict with a separate deposit processor. Confirm the person and Kendall facility in the live portal before payment, then review the displayed fee, limits, accepted method and refund terms. The FAQ also says cash bond can be posted, but Illinois ended cash bail on September 18, 2023. Do not follow that legacy sentence; use the current court order.

A successful deposit does not guarantee a purchase. Classification, debt, discipline, ordering deadlines and stock may affect commissary. Public sources do not disclose Kendall’s current fee, deposit cap, purchase schedule, item list, indigent-supply standard, negative-balance deduction detail, disputed-charge path or how remaining funds are returned after release or transfer. Keep the transaction ID. Ask JailATM about payment processing and the jail about the resident account, commissary eligibility and final balance.

The 2025 inspection says Advanced Correctional Healthcare provides 76 onsite nursing hours per week. It does not publish a family clinical line, after-hours triage route, medication or glasses acceptance, outside appointment workflow, pregnancy care, dental process, medical fees or health-record release. For an immediate threat call 911. Otherwise call 630-553-7500, state that you have time-sensitive health information, and give the person’s name, date of birth, allergies, diagnoses, prescription details, pharmacy/prescriber and your callback number. Ask staff to document and route the message; do not expect confirmation of protected health information.

The inspection records eight onsite mental-health-professional hours per week. For suicide risk, withdrawal, psychosis, threats or abrupt decompensation in custody, call the jail and describe observable facts; use 911 for an immediate emergency. For community treatment planning, Kendall County Health Department is at 811 W. John Street, 630-553-9100. Illinois CARES is 800-345-9049, and 988 is available for crisis support. Community lines do not replace an in-custody health alert.

The 2025 inspection found no standards noncompliance, but the public site does not publish the detainee grievance form, filing deadline, emergency grievance, appeal level, nonretaliation channel or family submission route. The detained person should record date, time, place, people, witnesses, requested remedy and every response, and keep copies where permitted. Families can ask the jail how to route a concern without replacing the person’s internal steps. For a jail-standards concern, Illinois Jail and Detention Standards can be reached at 217-558-2200; that office does not change a court order or provide emergency response.

Federal guidance requires effective communication and reasonable access in criminal justice, but the county pages reviewed do not name a jail ADA coordinator or publish ASL, captioning, mobility, service-animal, low-vision, cognitive, medication-device or language-assistance procedures. Call 630-553-7500 before a visit, court transport or release. State the functional barrier and requested accommodation, ask who owns the decision, request written confirmation and preserve denials. For KAT, request an accessible vehicle or travel-assistant arrangement during registration.

Report sexual abuse, harassment or staff misconduct through the Kendall PREA hotline at 630-381-9845. The mail page also lists sealed outgoing legal mail to Mutual Ground about PREA; Mutual Ground’s sexual-violence line is 630-897-8383. Preserve the person’s name, subject/booking number, dates, location, alleged actor, witnesses, injuries, retaliation risk and safest callback method. The public pages do not explain whether the county hotline is anonymous or outside-operated, evidence-preservation timing, third-party status updates or retaliation monitoring. Use 911 for immediate danger.

Kendall County Courthouse is at 807 W. John Street, Yorkville, IL 60560. Court administration is 630-553-4208; Circuit Clerk is 630-553-4183. Ask for the case number, next date, courtroom, filed detention/release order, conditions, warrants and whether another jurisdiction has a hold. Online records may lag or omit sealed details, and the courthouse viewing room is a records service—not a jail locator. Verify current custody separately.

Kendall County Public Defender is at 807 W. John Street, 630-553-4215. Ask the clerk whether counsel has been appointed and obtain the lawyer’s name; do not assume the Public Defender represents the person before appointment. Give counsel the booking/subject number, case number, next hearing, holds, medication urgency and family callback. Attorney video is not recorded or monitored under the county visit page, but the public site does not explain scheduling, attorney identity approval, privileged phone registration or electronic document exchange. Counsel should arrange those directly with corrections.

Illinois ended cash bail on September 18, 2023. The Sheriff FAQ’s 24-hour cash-bond instructions are legacy text and should not be used. The judge’s filed order controls detention, release and conditions. Pretrial Services is reached through the courthouse at 630-553-4208. Ask about check-ins, testing, GPS, curfew, travel, treatment, no-contact terms and how to request a modification. Before arranging pickup, ask the jail whether any warrant, other-county, IDOC, U.S. Marshals or immigration hold prevents release.

Use the Circuit Clerk for the criminal case file and the Sheriff Records Division for incident, arrest or agency records. Records walk-up is published as Monday–Friday, 8 a.m.–4:30 p.m.; call 630-553-7500 before travel. Ask which record is public, the exact date range, report or case number, fee, redaction and delivery method. Medical records, jail grievances, provider transactions and court files have different custodians; one request will not produce all of them.

The 2025 inspection records compliant property receipt and third-party written-authorization procedures, but the county does not publish the local form, eligible recipient, pickup days, ID standard, inventory dispute, abandoned-property deadline or release-clothing rule. Call 630-553-7500 with the name and subject/booking number. Ask whether the person must sign an authorization, which property can be released, exact desk/door, hours, acceptable ID and receipt. Do not travel on verbal family approval alone.

A displayed release date can change because of court action, sentence credit, transport, another jurisdiction or a hold. Ask corrections to identify each holding authority, whether release is direct or a transfer, expected destination, when the status may be confirmed again, and whether property, medication, clothing or transport need coordination. U.S. Marshals detainees and other Illinois-county detainees were present during the 2025 inspection; sending-authority instructions may differ. Do not attach ordinary Kendall release assumptions to a federal or outside-county movement.

The inspection verifies GED and substance-use-disorder programming, Casemaker legal research on Securus kiosks, and Aramark food service. It does not publish eligibility, enrollment, waitlists, completion records, reentry case management, identification documents, benefits enrollment, medication bridge or transportation at release. Ask the detained person to submit a request early. A family checklist should include signed release conditions, identification, prescriptions, court/pretrial appointments, phone access, transportation, safe housing and a plan for any transferred property or account balance.

The verified task address is 1102 Cornell Lane, Yorkville, IL 60560. Public sources reviewed do not identify the visitor lobby entrance, parking rows, release pickup point, after-hours door, passenger drop-off, service-animal route or continuous accessible path. Because Sheriff administration, records and the jail share the Public Safety Center, do not assume one door serves every task. Call 630-553-7500 and ask for the task-specific entrance, check-in time, parking location, mobility route and who to call from the lot.

Kendall Area Transit is demand-response public transportation, not a fixed jail bus. Registration is required at 630-882-6970; after registration, schedule at 877-446-4528. Published service is Monday–Friday, 6 a.m.–7 p.m., except holidays, with the last reservation at 6:30 p.m.; the reservation office is 8 a.m.–4 p.m. One travel assistant may ride free, and wheelchair assistance is limited to one step unless a travel assistant helps.

These are planning dates, not a booked ride or live arrival. The live page conflicts with itself on advance notice—4–14 days in one place, 2–6 days for general trips and up to two weeks for medical trips in another. Call before relying on any window. The 2025 release gave a $2–$5 range, not a guaranteed current fare.

This guide was reviewed on September 29, 2026. It treats the May 2025 state inspection as dated evidence, current county pages as local instructions, provider pages as transaction/support handoffs and the current court order as controlling release authority. The guide deliberately preserves the Securus/NCIC provider conflict, obsolete cash-bail sentence, contradictory KAT advance windows and unusual no-return-address mail sentence. Where no current public rule was found, it names the gap and responsible contact rather than inventing an answer.
