The local department shall: Review applications from those desiring to be considered as adult foster care providers. Review and approve or disapprove all applications within 90 days, after the local department has received all required documentation. If it is determined that there will be a delay in the approval or disapproval of the application, the local department shall advise the applicant, in writing, within 5 working days of the reason for the delay. Conduct a home study if a foster adult is already in the home when an application to be a provider is made. Due consideration is given to the importance of maintaining the home for the adult involved. If the home cannot be approved, the local department shall notify both the foster adult and the caregiver and offer them assistance to meet the standards or inform them of the possible alternatives and of the consequences of continuing in an unapproved home. Conduct an annual review of the foster care home and advise the caregiver in writing of continued approval or disapproval. Offer consultation and supportive services to caregivers.
