What's the difference between IHSS and WPCS hours?


Published: Oct. 8, 2025Updated: Oct. 8, 2025

Here is an at-a-glance comparison of the main differences between In-Home Supportive Services (IHSS) and Waiver Personal Care Services (WPCS) obtained through the HCBA waiver. (For a printable version, view this chart.)

In-Home Supportive Services (IHSS) Waiver Personal Care Services (WPCS)
Services Funds in-home care (personal care, paramedical services, and protective supervision) Funds additional in-home care hours using guidelines similar but not identical to IHSS
Program requirements Must have Medi-Cal, either based on income or through any waiver Must have Medi-Cal specifically through the HCBA waiver; must already be an IHSS recipient; must have a doctor's order (Plan of Treatment) specifying that they require WPCS in order to remain safely in their own home
Eligibility Child’s care needs must exceed that of a typically developing child of the same age because of their disability Child meets the criteria for admission to a skilled nursing facility and is already utilizing IHSS to the maximum extent possible
How to apply Contact local IHSS office Contact local HCBA Waiver Agency
How hours are allocated IHSS case worker assesses child’s needs compared to a typically developing child to assign hours HCBA Waiver Agency case worker and nurse team assesses child’s needs and medical necessity to assign hours
Maximum hours for recipient 283 hours per month Direct care hours from all sources (e.g. IHSS, WPCS, Regional Center respite, and EPSDT home health nursing hours) not to exceed 24 hours per day or 720 hours per month; child must use all available IHSS hours before they can receive WPCS hours, but they do not need to be receiving max IHSS hours (283)
Provider options Parents can be paid to serve as their child’s provider, or they can hire a third-party provider Parents can be paid to serve as their child’s provider only if they are unable to work full-time because of their child’s care needs, there is no other legally responsible provider available, and the child is at risk of being institutionalized otherwise; parents who do not meet the criteria must hire a third-party provider
Provider qualifications Must be 18 years old; must be eligible to work in the United States Provider must meet qualifications to be an IHSS provider
Provider pay rate Hourly rate varies by county; provider will fill out timesheet on the IHSS portal Same as IHSS hourly rate; provider will fill out timesheet on the IHSS portal
Maximum hours for provider 70:45 hours per week for one recipient, or 66 for two recipients; no defined limit on hours per day Same weekly limits as IHSS; for providers of both IHSS and WPCS, maximum of 12 hours per day of IHSS and WPCS combined (weekly max still applies); in some limited circumstances, the provider may claim 12 hours per day up to 360 hours per month, but exceptions must be approved by the Waiver Agency
