Care Homes for Adults with Developmental Disabilities in Washington

Developmental disability (DD) care homes serve adults with intellectual and developmental disabilities: Down syndrome, autism spectrum disorders, cerebral palsy, traumatic brain injuries (in some cases), and other conditions that affect cognitive and adaptive function across the lifespan.

Residents range from young adults transitioning out of family care to older adults aging in place. Many DD residents live in care homes for decades; placement decisions often span generations.

The Developmental Disabilities Administration (DDA) is the DSHS division that funds and oversees services for Washingtonians with developmental disabilities. DDA administers Medicaid waivers that pay for residential, day, and community-based services.

The main waivers families encounter: Basic Plus (limited services), CORE (broader services for moderate-need adults), Community Protection (for those needing more support), and IFS (individual family support).

Find your regional DDA office through dshs.wa.gov. Eligibility requires documentation of qualifying diagnosis and significant functional impairment.

A DDA-contracted AFH is not the same as a senior AFH that happens to accept a younger resident. The differences:

Specialized staff training. DD-focused homes have training in supporting adaptive function, behavioral support, communication accommodation, and integration with day programs and community life.

DDA case management. Each resident has a DDA case manager who oversees the person-centered plan, day program coordination, and benefit administration.

Different DSHS licensing pathway. Some DD homes are licensed as adult family homes; others are supported living, certified community residential services, or other configurations.

Individualized support plans built with the resident and their family. These cover personal goals, day program preferences, communication needs, and behavioral support strategies.

Community integration. Real participation in the community — volunteering, employment, recreation, religious or cultural activities. Not just outings.

Day program coordination. Many DD residents attend day programs, supported employment, or community participation programs during the day. The home should support those connections.

Behavioral support. Trauma-informed, positive behavior support — not punishment-based. Staff trained to redirect, de-escalate, and support without coercion.

Adults with developmental disabilities in Washington have the same legal rights as any other adult — to make choices, to privacy, to refuse care, to participate in their own planning, to be free from abuse, and to receive services in the least restrictive setting appropriate to their needs.

Washington's Disability Rights Washington and The Arc of Washington State are advocacy organizations that families turn to when concerns arise.

Start with your DDA Regional Office. Each region maintains relationships with contracted providers and can refer based on the resident's needs and waiver level.

The Arc of Washington, county developmental disability advisory boards, and parent networks are excellent sources of referrals to specific providers families have found responsive.

When evaluating a home, check DSHS inspection records →, talk to families currently using the home, and look for evidence of community integration and individualized planning — not just compliant care.

Q: Can my adult child stay in the same home for life? A: Many do, but as care needs change (medical complexity, aging-related issues) some residents move to a different setting.

Q: How is this paid for? A: Almost entirely through Medicaid via DDA waivers. Family contribution is rare except for personal expenses.

Q: What if my child has both DD and dementia (aging)? A: DDA can coordinate with HCS for combined services as needs evolve.

Q: How long is the waitlist? A: Varies by region and waiver — sometimes months, sometimes years. Apply early.
