Your child is turning 18 and every agency is changing the rules at the same time
The Social Security Administration is switching your child from the childhood disability standard to the adult standard — and a meaningful share of reviews end in cessation. Medi-Cal is reinstating asset limits that drop from $130,000 to $21,000 in 2027. The school district is transferring educational rights to a student who may not be able to exercise them. And the regional center is asking you to rewrite the IPP around adult outcomes while provider capacity has not kept pace with demand.
No government office in California coordinates any of this. The SSA does not notify the regional center when benefits are suspended. The school district does not alert DHCS when your child ages out. The county does not check whether Medi-Cal has lapsed. You are the systems integrator — and right now, the operation has no manual.
The Transition Command Center: Every Agency in One Sequenced Workflow
This guide is the manual. It maps every federal and state agency your family touches — SSA, DHCS, the Department of Developmental Services, the regional center, the school district, the Department of Rehabilitation — into a single chronological workflow where each filing builds on the last. The guide does not recite eligibility rules you can find on five different websites. It shows you the dependencies between agencies, the domino effects when one filing fails, and the precise order that prevents gaps.
What's Inside
- SSI Age-18 Redetermination Walkthrough — how the adult disability standard differs from the childhood standard, what evidence to assemble at age 17½, how to complete the Function Report with limitation-specific examples, and the 10-day benefit-continuation window that keeps payments flowing during an appeal
- DAC and Childhood Disability Beneficiary Pathways — how to calculate the 50%-to-75% derivative benefit from a parent's work record, the marriage restriction rules, and how the Social Security Fairness Act repeal of WEP and GPO restored full payment amounts retroactive to January 2024
- Medi-Cal Transition Protection — Section 1634 automatic enrollment, the SB 87 seamless-transition review when SSI stops, the 250% Working Disabled Program, and the reinstated asset limits under AB 116 with the two-tiered transition window ($130,000 through June 2027, then $21,000 afterward)
- Medi-Cal Asset Planning Worksheet — catalog countable versus exempt property, identify categorical exemptions (Deemed SSI, Pickle Amendment, DAC Medi-Cal), and plan CalABLE or special needs trust transfers before the July 2027 cliff
- Regional Center and Self-Determination Program Guide — how the Lanterman Act entitlement works in practice, why vendored-provider capacity bottlenecks block authorized services, and how the SDP converts your paper entitlement into a direct budget you control
- CalABLE Account Strategy — the $20,000 standard contribution limit, the $15,650 ABLE-to-Work add-on, the $100,000 SSI resource exclusion, the age-46 onset expansion effective January 2026, and the Trump Account rollover path for families with children born 2025-2028
- Work Incentives Sequencer — the $85 general-plus-earned income exclusion, the Student Earned Income Exclusion ($2,410/month for working students under 22), Section 1619(b) continued Medi-Cal, and how California's Department of Rehabilitation Work Incentive Planners coordinate state and federal exemptions
- Decision-Making Authority Selector — the precise legal and administrative differences between limited conservatorship, supported decision-making, durable power of attorney, and representative payee status — so you know which tool you need and which ones you can skip
- Education Code 56026 Exit Calculator — pinpoints the exact date special education services terminate based on birth month, so you can align the school-to-adult handoff with the regional center IPP
Who This Guide Is For
- Parents whose teenager with a disability is approaching 18 and who need to prepare for the SSI redetermination, secure Medi-Cal continuity, and coordinate the regional center transition
- Families who already received the age-18 redetermination packet and need to respond correctly within the 10-day benefit-continuation window
- Parents of young adults aged 18–22 still enrolled in special education who need to plan the school-exit-to-adult-services handoff before IDEA eligibility ends
- Families navigating the Self-Determination Program because their regional center cannot deliver authorized services through vendored providers
- Parents who assumed legal authority continued automatically at 18 and discovered that doctors, schools, and agencies now require formal decision-making documents
Why the Free Information Is Not Enough
DB101 has excellent benefit calculators, but they do not sequence your filings across agencies. TASK and Parents Helping Parents run workshops focused on K-12 IEP rights, but their coverage stops where adult financial safety nets begin. The Disability Rights California publications explain each program in isolation, but they do not map the domino effect — how a change in SSI income alters your county Medi-Cal share of cost, which changes IHSS eligibility, which affects the regional center's payor-of-last-resort calculation. Special needs attorneys can coordinate the whole picture, but initial consultations alone run $3,000 to $10,000 for conservatorship and trust setups.
This guide organizes the verified pathways across every agency into one sequenced workflow — for a fraction of one billable hour.
