Tri-Counties Regional Center (TCRC) serves San Luis Obispo, Santa Barbara, and Ventura counties — one of California’s 21 regional centers under the Lanterman Act WIC §4500, free at any family income. Its territory runs roughly 200 miles of coast, so TCRC operates seven offices: Santa Barbara, Santa Maria, San Luis Obispo, Atascadero, Ventura, Simi Valley, and Fillmore. Its application asks your child’s age first — under 3 and 3 and older follow different tracks.
Is Tri-Counties my regional center?
If you live in San Luis Obispo, Santa Barbara, or Ventura county, yes. The boundary is the county line — clean, unlike Los Angeles County an hour to the south, where seven centers split one county by health district and a family’s street address decides.
Around the edges: Monterey and San Benito to the north belong to San Andreas Regional Center; Kern, Inyo and Mono over the mountains belong to Kern Regional Center; the far side of the Ventura county line is Los Angeles County and a different center entirely. What decides your case is where your child lives — not the school district, not where the pediatrician is. Our Regional Center finder confirms it in seconds.
Which office should I be dealing with?
TCRC runs seven offices, and that is the most useful local fact on this page. From Paso Robles to Fillmore is several hours of driving. Before you accept an appointment, ask: “Which office is closest to me, and can my meetings happen there?” Nobody will volunteer it.
| County | TCRC offices |
|---|---|
| San Luis Obispo | San Luis Obispo · Atascadero |
| Santa Barbara | Santa Barbara (headquarters) · Santa Maria |
| Ventura | Ventura · Simi Valley · Fillmore |
TCRC’s offices keep standard weekday business hours, which is its own kind of barrier when you work a shift or farm schedule. Addresses and numbers for all seven are on the center’s own page — worth bookmarking rather than copying, because branch numbers change:
Tri-Counties — office locations →How does intake start here?
The application asks one question before anything else: is the person seeking services over age 3, or under age 3? That single choice sets which track you are on and which clock runs.
| Your child’s age | Track | The clock |
|---|---|---|
| Under 3 | Early Start | 45 days from referral to the evaluation and assessment 17 CCR §52086 |
| 3 and older | Standard Lanterman intake | 15 working days to intake WIC §4642, then 120 days to a completed assessment WIC §4643 |
After you apply, TCRC connects you with an Intake Coordinator. Get that person’s name, direct number, and email on the first contact, and write down the date you applied. On a territory this size, the coordinator is your single point of contact, and the date is what every deadline runs from.
What to bring — what exists, not a perfect folder:
- Pediatrician notes, referrals, developmental screening results
- Any evaluation: speech, occupational therapy, psychological, hearing
- Preschool or school records; an IEP or IFSP if there is one
- Your own written description of a hard day, in specifics
A diagnosis is helpful and not required to begin. TCRC funds its own assessments at no cost to you.
What are the deadlines, exactly?
15 working days from your request to initial intake WIC §4642. 120 days from intake to a completed assessment — 60 days where delay would risk your child’s health, safety, or development WIC §4643. Under 3: 45 days from referral for the Early Start evaluation and assessment 17 CCR §52086. Then 60 days from the completed assessment to the written plan WIC §4646.
Those are statewide and they do not stretch for distance. A long drive is your logistics problem and TCRC’s scheduling problem — it is not a lawful reason for the assessment to run past 120 days. If a clock passes, write to your coordinator with the date you applied, the statute, and a request for a decision date.
Eligibility at 3 and older: a developmental disability that began before 18 and is a “substantial disability” — significant functional limits in 3 or more of 7 life areas WIC §4512. Under age 5, ask about provisional eligibility by name — it needs limits in at least 2 of those areas rather than 3 WIC §4512.
Three counties on one page looks tidy. On the ground it is mountain passes, a two-lane stretch of the 101, and an appointment that eats a workday. That is a real cost and you are allowed to name it out loud: “the nearest office to me is X — can we meet there, or by video?” Asking early is the difference between one drive and four.
What if Tri-Counties says no?
A denial must arrive as a written Notice of Action explaining the decision and your appeal rights. A phone call saying “that’s not something we fund” is not a decision and starts no clock — ask for the written notice. From it you have 60 days to request a hearing WIC §4710.5. Check the dates printed on your own notice.
The Office of Clients’ Rights Advocacy (OCRA), part of Disability Rights California, provides free advocates who handle regional center appeals statewide. It costs nothing and it changes the room.
