California’s developmental disabilities system is entering a period of structural change. As of November 2025, the Department of Health Care Services (DHCS) has announced its intent to submit a proposed amendment to the state’s 1915(c) HCBS Waiver for Individuals with Developmental Disabilities (Waiver CA-0336) by November 28, 2025, with a proposed effective date of March 1, 2026.
This does not represent an immediate regulatory shift but it does signal California’s direction for 2026 and beyond. Waiver amendments shape how services are delivered, funded, monitored, and documented. For adult day programs, home care agencies, and providers supporting individuals with intellectual and developmental disabilities (I/DD), this transition window provides a crucial opportunity to prepare before new expectations solidify.
The most strategic agencies aren’t waiting for March 2026. They are using this period to strengthen their documentation, compliance workflows, and reporting systems so they are ready for whatever the amendment finalizes.
Why This Amendment Matters — Even Before It Becomes Active
Waiver CA-0336 is one of California’s primary mechanisms for supporting individuals with developmental disabilities in community settings. Any amendmen large or small can reshape parts of the service ecosystem. The November announcement signals that California is updating components of its DD service structure to better align with HCBS standards, federal expectations, and statewide quality goals.
These changes may improve access, clarify service definitions, adjust provider qualifications, or modernize documentation expectations. Providers may also face clearer requirements around quality indicators, person-centered service delivery, and performance tracking.
Even if the amendment details remain in development, its timeline offers a rare advantage: early visibility. Providers have months to organize, modernize, and refine internal systems before any changes come into effect.
Understanding California’s Direction Through Industry Signals
Although the full amendment text is still under review, the shift itself gives insight into California’s priorities. Recent statewide discussions highlight recurring themes equity, transparency, person-centered planning, clear communication with families, and improved outcome tracking. These themes often precede updates to how waiver services must be documented and monitored.
The following table summarizes what the amendment timeline signals compared to what providers may eventually experience.
What the Amendment Timeline Suggests About California’s Direction
| State System Signals | What This Likely Means for Providers |
| Emphasis on modernization | Stronger expectations for digital documentation and data accuracy |
| Higher accountability in HCBS programs | Need for clearer service notes, caregiver logs, and audit trails |
| More attention to person-centered outcomes | Improved care plans and tracking of measurable progress |
| Shifts toward transparent processes | On-demand access to records for families and reviewers |
| Preparation for future CMS alignment | Adoption of systems that can meet federal audit standards |
These patterns position 2026 as a year of transition where providers will benefit from having reliable, compliant, and efficient systems already in place.
How Home Care & Adult Day Care Providers Should Prepare
California’s DD delivery structure has expanded significantly over the last decade, and new amendments often refine documentation rules, enhance quality standards, or modify how services are authorized and billed. Providers who wait for formal implementation typically rush to update processes under pressure leading to operational disruption, billing delays, or compliance gaps.
By contrast, agencies that prepare early benefit from stability and readiness.
Strengthening documentation processes, adopting standardized workflows, improving caregiver communication, and ensuring audit-ready reporting are key steps providers can take during the transition window. Many organizations in California are proactively shifting to digital platforms that automate compliance tasks and eliminate manual data risks.
Solutions like those offered by adult day care software providers in California by myEZcare support this shift by helping agencies streamline service notes, improve transparency, strengthen EVV logs, and ensure reliable Medicaid-aligned documentation. Utilizing structured software during a waiver transition protects agencies from compliance surprises and allows them to meet future expectations without heavy operational stress.
What March 2026 Really Represents for California Providers
The effective date does not necessarily mean major changes will occur all at once. Instead, March 2026 represents the beginning of a new chapter. California often rolls out changes in phases, allowing providers to adapt gradually. This means agencies that begin improving their systems now will move smoothly into the next stage of waiver evolution.
Providers who monitor their data quality, documentation consistency, and caregiver communication workflows will find themselves at an advantage when new requirements are introduced.
To better understand how providers can align with future expectations, the table below highlights how transitioning early with better systems creates long-term operational strength.
Why Early Preparation Offers Long-Term Benefits
| Preparation Area | Outcome for Providers in 2026 |
| Better data accuracy | Faster adaptations to new documentation rules |
| Consistent workflows | Reduced training time once changes roll out |
| Person-centered planning tools | Smoother compliance with outcome-based requirements |
| Seamless record access | Stronger family communication and trust |
| Audit-ready reporting | Confidence during state reviews and CMS evaluations |
Preparing early ensures that providers maintain control over their operations instead of reacting to unavoidable state changes under pressure.
FAQs
1. Does the November 2025 waiver amendment immediately change provider rules in California?
No. The amendment is proposed and will be submitted by November 28, 2025, with a planned effective date of March 1, 2026. Providers should treat this as a transition period rather than an active rule change.
2. Will adult day programs be affected by this waiver amendment?
Likely yes, depending on the final language. Adult day programs are often included in HCBS waiver updates, especially when documentation or quality expectations are refined.

Yes. Preparing early prevents last-minute disruption and ensures agencies can meet new requirements smoothly once finalized.
4. What kind of documentation will matter more under updated HCBS expectations?
Person-centered service notes, measurable outcomes, caregiver logs, communication records, and audit-friendly reporting will play a larger role as California modernizes its DD service structure.
5. Do providers need new technology for the upcoming changes?
While not mandatory, updated digital systems significantly reduce compliance risk and improve readiness for evolving documentation standards.
