Inland Regional Center (IRC) serves all of Riverside County and all of San Bernardino County — no neighbourhood boundaries to decode, just two county lines. It is one of California’s 21 Regional Centers under the Lanterman Act WIC §4500, and services are free to your family at any income. Once intake begins, an assessment is due within 120 days WIC §4643 — or, for a child under 3, evaluation and the initial family service plan within 45 days of the referral 17 CCR §52086.
Is Inland my Regional Center?
If your home address is in Riverside County or San Bernardino County, yes. That covers Riverside, San Bernardino, Ontario, Fontana, Rancho Cucamonga, Moreno Valley, Corona, Temecula, Murrieta, Hesperia, Victorville, Palm Springs, and everything out to the desert.
There is no puzzle here of the kind LA County families face — no health districts, no ZIP-by-ZIP splits. But there is a different problem, and it is distance. These two counties together run from the edge of Los Angeles out toward the Nevada and Arizona state lines. A family in Blythe or Needles and a family in Chino are served by the same center and do not live in remotely the same world.
So the practical question is not which center but which office and which coordinator. Ask on the first call: which office will hold my child’s file, who is my service coordinator, and can assessments happen closer to home or by video? Inland’s website blocks automated checking, so this page can’t publish a current office list for Riverside and San Bernardino counties it hasn’t been able to verify — get the address and hold onto it once intake gives it to you.
How does intake actually start here?
Call the main line at the top of this page, say your child’s age, and say which county you live in. For a child under 3, the state’s own directory lists a separate Early Start intake contact for Riverside County and for San Bernardino County — so naming your county in the first sentence gets you to the right queue instead of a transfer.
That county-by-county split is the single most useful local fact on this page. Most centers run one Early Start intake queue; Inland runs two, because it is covering two counties’ worth of referral systems, school districts, and hospitals. If you call and get “that’s not us,” the fix is almost never that you have the wrong center — it is that you have the wrong county’s desk. Ask to be transferred, and ask them to confirm the date your request was received either way.
Under 3: evaluation, eligibility, and the initial family service plan are all due within 45 days of the referral 17 CCR §52086. Age 3 and older: assessment due within 120 days of intake, or 60 days when a delay would risk your child’s health, safety, or development WIC §4643. Calendar it the day you first call.
Have ready: your child’s date of birth, your address and county, any diagnostic or psychological reports, the most recent IEP or IFSP, school or daycare notes, and a list in your own words of what your child struggles with on an ordinary day. Missing paperwork is not a reason to delay the call. The center pays for its own assessments.
Inland’s website blocks automated checking, so this page can’t confirm whether the application arrives as an online form or a packet returned by mail, fax or email, or exactly which records it asks over-3 applicants to attach — ask at your first call and confirm in writing.
Two counties, a lot of families, and a phone system that was not designed by anyone who has ever held a screaming toddler on their hip. If your first attempt ended in a voicemail you never got a call back from, that was not a verdict on your child and it was not a hint to stop. Try once more, and this time ask for one specific thing before you hang up: the date your request was received, in writing. That one sentence changes a wait into a deadline.
Who qualifies?
No diagnosis is required to ask. For a child 3 or older, eligibility means a developmental disability beginning before age 18 that causes significant functional limits in 3 or more of 7 life areas WIC §4512. Under 3, Early Start uses broader delay-or-risk criteria. Ages 3 and 4 can also qualify provisionally on 2 of 5 areas.
The seven areas: self-care, receptive and expressive language, learning, mobility, self-direction, capacity for independent living, and economic self-sufficiency — each judged against what is expected at your child’s age. Autism, intellectual disability, cerebral palsy and epilepsy are named in the statute, along with conditions closely related to intellectual disability or requiring similar treatment.
The provisional route matters for young children and is easy to miss: a disability that is not solely physical and causes significant limits in at least two of five areas — self-care, language, learning, mobility, self-direction — can qualify a 3- or 4-year-old. It is temporary. The center must reassess before your child turns 5, and the full three-of-seven standard applies from then WIC §4512. Put that date in your calendar the day the letter arrives, and use the years in between to build the record.
What’s the same everywhere, and what’s local?
The law does not change between counties. Eligibility, the 45- and 120-day clocks, the written Notice of Action, and the appeal route are identical at all 21 centers. What is local at Inland: the two-county intake split, which office holds your file, how far you have to travel, and which providers exist near you.
Keep that line clear in your head, because in a service area this large you will hear a lot of “that’s just how it works out here.” Sometimes that is true — a rural corner of San Bernardino County genuinely has fewer vendored providers than Ontario does. But a shortage of providers is not a lawful reason to deny a service your child’s plan calls for, and neither is a budget. If a service is in the plan and nobody will deliver it, that is a problem the center owns, not you.
The state’s Regional Center directory also lists a cultural specialist and a language-access manager at every center, Inland included — a useful role to ask for by name if you are not being served in your own language.
What if Inland says no?
Get it in writing. A denial must come as a Notice of Action stating the decision and your appeal rights. A no on the phone starts no clock and cannot be appealed — so ask, every time: “Please send me that decision as a written Notice of Action.”
Once the notice arrives, read the dates on it and calendar them that day. The appeal itself is California procedure, identical in Victorville and in San Francisco.
How to appeal a Regional Center denial, step by step →Free help exists. The Office of Clients’ Rights Advocacy (OCRA), part of Disability Rights California, staffs advocates who handle Lanterman Act appeals for families at no cost — worth contacting before you write anything. (They are a resource, not the rule; the deadlines that bind come from the statute and from the dates printed on your own notice.)
You worked out which county desk you needed, asked for your date in writing, and learned the standard your child will actually be measured against. That is a good day’s work in a system that does not make any of it obvious.
