The Lanterman Developmental Disabilities Services Act is California's landmark law guaranteeing that people with developmental disabilities — including autism, cerebral palsy, epilepsy, and intellectual disability — have a right to services and supports that enable them to live as independently as possible. Enacted in 1969 and strengthened in 1977, the Lanterman Act establishes the Regional Center system: 21 nonprofit agencies across California that coordinate assessments, develop Individual Program Plans (IPPs), and fund services. Regional Centers serve as the gateway to California's developmental disability services regardless of age or income. Services include respite care, behavioral services, supported living, day programs, transportation, and family support. The Lanterman Act is an entitlement — once eligible, individuals cannot be waitlisted for core services.
California families should apply to their Regional Center as a first step. The Lanterman Act provides an entitlement separate from HCBS waivers. Waive Help's Atlas highlights California's unique system.
