In North Carolina, a home care agency is licensed by DHSR to give care at home, including hands-on in-home aide care. A home health agency is a licensed home care agency that is also Medicare-certified: "Home Health means a licensed home care agency which is certified to receive Medicare and Medicaid reimbursement for providing nursing care, therapy, medical social services, and home health aide services".
The difference that matters for a new owner: "To become a medicare certified home health agency, a Certificate of Need (CON) must be obtained." And the 2026 State Medical Facilities Plan says of new Medicare-certified home health agencies: "It is determined that there is no need anywhere in the state and no reviews are scheduled."
So a new agency starts as a licensed home care agency ($510 a year, no Certificate of Need). If you will only offer companion, sitter or respite care, you need a home assistance services provider license instead.
