The Six Time Blocks
The published schedule, effective April 10, 2026, runs six blocks a day:
| Block | Time |
|---|
| 1 | 9:30 to 10:00 AM |
| 2 | 10:30 to 11:00 AM |
| 3 | 12:00 to 12:30 PM |
| 4 | 1:00 to 1:30 PM |
| 5 | 6:00 to 6:30 PM |
| 6 | 7:30 to 8:00 PM |
Columns run Sunday, Monday, Tuesday, Thursday, Friday and Saturday. There is no Wednesday column, which matches county policy setting face-to-face visits daily except Wednesdays.
Why You Need the Housing Unit First
Each cell in that grid lists which housing units visit in that slot, using labels like 21-ABC, 23-A, 24-ABCE, 32-ABC, 35-DEF, OPHU, and numeric groups such as 1-A, 2, 4, 6, 7-ACDEF, 8-ABCD and 9.
So the schedule does not say “visiting is at 10:30.” It says unit 24-ABCE visits at 10:30 on a Thursday. Without the housing unit, the grid is unreadable.
The county’s inmate locator does not give you the housing unit. 925-551-6500 does. Ask for it in the same call where you confirm custody, because the same unit also determines which day commissary is delivered.
Booking
Registration and scheduling happen at the county’s visitation portal. Video visits can also be scheduled through the vendor’s own site.
To register, each adult 18 or over supplies: name, address (the county states that PO boxes are not acceptable), telephone number, date of birth, driver’s licence number and email address.
To book, you also need the person’s name, their PFN and their date of birth.
Video visiting is provided by ViaPath Technologies, and the county is careful to say the service is therefore not guaranteed by the Sheriff’s Office. Vendor support is 1-855-208-7349.
The No-Show Rule
Miss two scheduled public visits within 30 days and visiting privileges are suspended for 30 days from the date of the second one. Further no-shows can bring a 60-day suspension.
One protection worth knowing: arriving and being turned away does not count as a no-show. If you are refused at the door over ID or dress, that is not held against you under this rule.
Check-in opens 30 minutes before the scheduled time. The county’s written late-arrival warning appears under its professional visiting rules and says failure to arrive on time may mean the visit is cut short or rescheduled. Whether an identical written rule covers public visits is not published, so arriving inside the check-in window is the safe approach.
Who Can Visit, and Who Cannot
Caps: no more than four adults and four children, with a maximum of four people in the booth at a time. Each person in custody gets one visit per day.
ID accepted: a valid driver’s licence, California identification card, state identification card, passport, Matriculate Consulate card, or other official government-issued identification showing a photograph, physical characteristics and signature.
Children must be accompanied by a parent or legal guardian. County policy is stricter than the public page here and worth following: the accompanying adult must provide a birth certificate showing that either they or the person in custody is the minor’s parent, and an original or copy is required for each visit. A minor married to the person inside is exempt from the escort rule with a court-sealed marriage certificate.
Criminal history restrictions, which turn away more visitors than any other rule:
- Anyone confined in the Alameda County jail system in the last six months needs prior authorisation.
- A prior felony involving violence, or bringing contraband into a jail, needs written permission.
- Any other felony needs written permission unless three years have passed since release on it.
- Anyone on probation, parole or post-release community supervision needs written approval. For a video visit, their own supervising officer must approve as well.
- A visitor with an active warrant is denied entry and may be arrested.
Screening
Two metal detectors in the lobby. County policy sets out the escalation precisely: three attempts through the walk-through, then a handheld wand, then a pat-down by a sworn member of the same gender away from public view. Refusing at either stage means entry is refused.
Excessive jewellery is worth removing before you arrive, because three metal-detector failures sends you to the back of the line.
What Not to Wear
Prohibited: gang colours on hats, belts, bandanas, shoes or sportswear; obscene language or drawings; visible gang or hate-related tattoos and body art; sleeveless, strapless, halter or spaghetti-strap tops; swimsuits; bare midriffs; shorts or skirts exposing more than mid-thigh, slits included; visible undergarments; sheer or see-through fabric; pyjamas; non-removable metal buckles; bib overalls with metal; steel-toed boots or shoes.
Visitors must be fully clothed and wearing shoes or sandals, and the county states that visitors will not be permitted to remove a sweater or jacket if doing so would then breach the dress code. Lobby staff and the Visiting Unit make the final call.
The video dress code applies in your own home. No tank tops, half tops, spaghetti straps or swimwear, no sheer fabric or exposed undergarments, no gang attire, no hats, bandanas or beanies. Video visits are recorded and monitored, faces must stay in view, and photographing the screen or adding a third person ends the visit. A parent or guardian must be present for anyone under 18.
What to Leave in the Car
No laptops, phones, cameras, recorders, purses, bags, briefcases, strollers, carriers or writing implements. Lockers are in the lobby and unclaimed items are removed and disposed of. Phones cannot be used in the lobby at all. No food or drink, with one exception: one diaper and one bottle for an infant.
Accessibility
Visiting rooms are equipped for disabled visitors, and the county asks you to call 925-551-6500 as early as possible for assistance, including help with the main entrance ramp. Wheelchair users and people with mobility concerns visit in the Outpatient Housing Unit visiting area. Every housing unit used for visiting has ADA-reserved booths. Hearing-impaired visitors can use Station Number 4 in the lobby, a mobile video device, or TTY. Service animals are expressly admitted.
Getting There Without a Car
The Sheriff’s Office maintains taxi and bus stops at the front of the jail, and states that the local bus system has regularly scheduled stops connecting to BART. A sign in the lobby posts routes, schedules and hours. Specific route numbers are not published online, so that lobby sign, or the 925-551-6500 line, is where to get them.
