West Valley Detention Center is the San Bernardino County Sheriff's jail at 9500 Etiwanda Avenue in Rancho Cucamonga. Confirm someone is held there through the Sheriff's online Inmate Locator, which covers all four county jails. Visiting needs advance scheduling, and release comes through a citation, bail, an own-recognizance order, or whatever a judge decides at arraignment.
How do I confirm someone is at West Valley Detention Center?
Search the Sheriff's Inmate Locator; the result names the actual housing facility, so confirm it says West Valley before making the trip.
- Open the Sheriff's Inmate Locator.
- Enter the 10-digit booking number if you have one, or the last and first name with a date of birth (or an approximate age) and sex.
- Check that the result's housing facility reads West Valley Detention Center, and note the booking number.
- The result also shows bail status and a projected release date, but the department warns it "may not reflect the current court appearance date," so confirm hearings with the Superior Court instead.
- If the name does not appear, some bookings are withheld under a Government Code exemption; call West Valley directly for information.
Where is West Valley Detention Center, and who does it house?
West Valley Detention Center (WVDC) is at 9500 Etiwanda Avenue, Rancho Cucamonga, CA 91739, and mostly holds people whose cases are still pending.
The facility's own page calls WVDC "one of the largest county jails in the State of California," opened in 1991, with a bed capacity of 3,347 and 50,000 to 60,000 bookings and releases a year. "Pre-trial inmates make up the majority of the population," and the facility runs two medical and mental health housing areas staffed around the clock, along with dental care, worship services, and instructional programs in culinary arts, laundry services and landscape maintenance. Court appearances for inmates held here are handled "by remote video for various locations including San Bernardino, Fontana, Rancho Cucamonga, Chino, Victorville, and Barstow courts," with the Sheriff's Transportation Division driving anyone who must appear in person. West Valley's own page lists its phone as (909) 708-8371; the Sheriff's countywide Corrections/Jails directory instead lists (909) 350-2476 for West Valley, the same number it gives as the department's Bail Information Line, so confirm which number fits your purpose.
How does booking and release work at West Valley?
Most people booked here are released the same way as at any San Bernardino County jail: by citation, posted bail, a judge's order, or completing a sentence.
Someone cited and released on a misdemeanor is not held for court; others leave on posted bail, an own-recognizance or other court-ordered release, when no case is filed, or after finishing a sentence. The department's general release guidelines put a completed sentence between 6:00 a.m. and 6:00 p.m., and an own-recognizance, cite, or court-ordered release generally the same day between 6:00 a.m. and midnight, while a release needing a medical, mental health or structured-living plan happens any time, case by case. Property that family or friends can pick up or drop off is limited to clothing, money, prescription medication and legal paperwork, and it is released only once the inmate signs a property withdrawal slip and the person picking it up shows identification. Bail can be paid at any county jail by cash, check, money order, property bond or bail bond (cash bail and bail bonds 24 hours a day), and before arraignment the amount starts from the court's Felony and Misdemeanor Bail Schedule (effective January 1, 2026, revised June 4, 2026), which calls itself "a guideline." At arraignment, In re Humphrey requires the judge to weigh ability to pay and nonfinancial conditions, and In re Kowalczyk (2026) allows bail to be denied in a noncapital case only for the offenses in California Constitution article I, section 12(b) and (c), while money bail "must generally be set in an amount that is reasonably attainable"; the firm's countywide San Bernardino County jail guide covers the schedule in depth. The firm's bail amount explainer and its surety bond versus cash bail comparison cover the general mechanics of posting bail anywhere in California.
How do I visit, send money or send mail?
Visiting needs an appointment booked the day before, and the Sheriff's countywide rules set the visiting days and hours at all four county jails.
The Sheriff's countywide rules, effective March 1, 2022, set visiting "Wednesday to Saturday, from 8:30 a.m. to 7:00 p.m." at all four jails. The Tuesday through Saturday, 8:00 a.m. to 5:30 p.m. hours on West Valley's own page sit under "Inmate Visiting Appointments," the same days and hours the Sheriff's directory gives for calling the Visiting Appointment Line; confirm the visiting window when you book. Booking happens online through the Inmate Locator, or by phone at (909) 887-0364 a day ahead; nobody gets in without that advance step. A visit here is capped at two people per inmate and two visits a week, one hour combined, and every visitor is asked to show up 30 minutes ahead for the search and identification check. Once a child turns 12, the department lets that child see an incarcerated parent alone, and a spouse under 18 can come too with a marriage certificate and photo identification in hand. Anyone with a past California prison felony term needs the facility commander's sign-off before setting foot on the grounds at all; skipping that step is itself a new felony under Penal Code 4571.
- Money: the lobby deposit kiosk takes cash, credit or debit cards around the clock, not personal checks or money orders.
- Mail: list the sender's name and return address plus the inmate's name and booking number on the outside of the envelope, sent to West Valley Detention Center, 9500 Etiwanda Avenue, Rancho Cucamonga, CA 91739. The jail takes lined paper and thin postcards only; cardstock, stickers and glitter get rejected, the Inmate Locator's mailing rules allow no more than 10 photos at a time, and a book or magazine has to arrive straight from its publisher or a recognized online seller.
What happens at the first court date, and which court hears the case?
A person held here must be brought before a judge within 48 hours of arrest, excluding Sundays and holidays; the court's filing rules, not the jail, decide which courthouse.
Penal Code 825(a)(1) sets that 48-hour limit for a person held in custody, "excluding Sundays and holidays," so a Saturday still counts. When the 48 hours expire while the court is not in session, section 825(a)(2) extends them "to include the duration of the next court session on the judicial day immediately following," and a person arrested on a Wednesday after that day's court session must be brought before a judge by the following Friday, as long as neither day is a court holiday. The firm's step by step guide to a California arraignment covers what happens once that hearing starts. West Valley's own page lists remote-video appearances for San Bernardino, Fontana, Rancho Cucamonga, Chino, Victorville and Barstow courts, but that only describes how an inmate held here appears; it does not decide which courthouse has the case. For that, see the firm's San Bernardino County courthouse assignment guide, which sorts the county's cities into its four criminal courthouses.
What should I do right now?
Confirm the person is actually at West Valley, then get ready for the visiting rules and the first court date.
- Search the Inmate Locator to confirm the housing facility and booking number.
- Call the Visiting Appointment Line, (909) 887-0364, to confirm the current visiting hours before driving to Rancho Cucamonga.
- If posting bail, bring an accepted payment form and the booking number; the firm's countywide San Bernardino County jail guide covers the schedule and how to ask for a lower amount.
- Gather the citation or arrest paperwork, since it names the court where the case will actually be heard.
A consultation with a Rancho Cucamonga criminal defense lawyer before that first hearing can cover bail strategy and what comes next, even when the case is heard somewhere else in the county. The firm's California courthouses and jails hub lists every one of these guides, including this one.
Frequently asked questions
Is West Valley Detention Center the same as the San Bernardino County Jail?
Not exactly. West Valley is one of four jails the Sheriff runs countywide; the firm's San Bernardino County jail guide covers all four and the countywide lookup, bail and release rules.
Which phone number actually reaches West Valley?
Both are real but come from different Sheriff's pages: the facility's own page lists (909) 708-8371, while the countywide Corrections/Jails directory lists (909) 350-2476, also printed as the Bail Information Line.
How do I put money on an inmate's account at West Valley?
Use the lobby deposit kiosk, open 24 hours a day; it accepts cash, credit or debit cards, not personal checks or money orders.
Can I drop off clothing or pick up someone's property at West Valley?
Only a short list qualifies: clothing, money, prescription medication and legal paperwork. Nothing goes out the door until the inmate has signed a withdrawal slip and the person picking it up has shown ID.
Does my court hearing happen at West Valley?
No. West Valley is a jail, not a courthouse; appearances happen by remote video or transport to the courthouse that actually has the case, which the court's filing rules decide.
Can I visit the same day I find someone on the Inmate Locator?
No. Every visit, online or by phone, must be scheduled at least a day ahead; there are no same-day visits at West Valley or any San Bernardino County jail.
