Maine Section 21 vs Section 29 Waiver: Which One Does Your Family Need?

Two Waivers, Very Different Scope

Maine operates two MaineCare Home and Community-Based Services waivers for adults with intellectual disabilities or autism spectrum disorder. Both are administered by the Office of Aging and Disability Services (OADS), but they differ in the intensity of support they provide, their enrollment structure, and their waitlist dynamics.

Section 21 is the comprehensive waiver. It covers intensive residential supports (shared living, group homes, 24-hour staffing), community support and day habilitation, supported employment with ongoing job coaching, respite, transportation, and crisis intervention. Section 21 enrollment is capped at roughly 3,000 individuals statewide, which creates the waitlist that families dread.

Section 29 is the community-focused waiver. It covers home support, community inclusion, work specialist services, and career planning — but not the intensive residential placements that Section 21 provides. Section 29 was designed for individuals who can live more independently but need structured support for employment, daily living, and community participation. Its enrollment model is uncapped, and Governor Mills' 2025 biennial budget allocated $34 million to systematically eliminate the Section 29 waitlist.

The Section 21 Priority System

The Section 21 waitlist is structured by priority levels that determine who receives services first:

Priority 1 is reserved for individuals in immediate crisis — imminent homelessness, caregiver death or incapacitation, or safety situations requiring emergency placement. These cases are addressed as they arise, outside the normal waitlist sequence.

Priority 2 covers individuals whose primary caregiver is aging (typically over 60) or has a documented health condition that will predictably limit their ability to continue providing care. The logic is preventive: placing someone before a crisis hits is cheaper and less traumatic than emergency placement.

Priority 3 is the general waitlist — individuals who need Section 21 services but don't meet the urgency criteria of Priority 1 or 2. Wait times at Priority 3 have historically stretched to multiple years.

For transition-age youth, the practical question is where they land on this priority structure. A 20-year-old whose parents are healthy and in their late forties will typically enter at Priority 3. A 20-year-old being raised by a grandparent in their seventies may qualify for Priority 2. Understanding the priority system helps families set realistic timelines and plan interim supports.

When to Apply for Each

The conventional strategy for families of transition-age students is to apply for both. Section 29's uncapped enrollment means faster access to community supports and employment services, while the Section 21 application secures a place on the waitlist for more intensive services if they're needed later.

OADS intake can begin at age 18, though the Lifespan Waiver (launching May 1, 2027) will allow enrollment as early as age 14. Families should initiate the intake process through OADS well before the student's school exit date — ideally two years before — so that case management is in place before school services end; under the Lifespan Waiver, the SIS-A needs assessment is administered by Maximus.

What Changes with the Lifespan Waiver

The Lifespan Waiver ("A Path for ME") is designed to replace the bifurcated Section 21/Section 29 structure for new applicants. Instead of choosing between two waivers with different service menus, individuals will receive a service package calibrated to their SIS-A assessment results, organized into budget groups that correspond to support intensity levels.

Current Section 21 and Section 29 waiver recipients are scheduled for voluntary transitions after a two-year phase-in period beginning in January 2027. Families on a waitlist should track OADS communications for details about their transition path.

For families just beginning the transition process, the practical advice remains the same: apply early, follow the applicable intake process, and maintain documentation of support needs as the waiver transition proceeds.

The Maine IEP Transition to Adulthood Guide includes a waiver comparison worksheet and application timeline tracker for coordinating Section 21, Section 29, and Lifespan Waiver applications alongside the IEP transition plan.
