If the department determines that grounds exist under section 20165 for denial, suspension, or revocation of a life support agency license but that the denial, suspension, or revocation of the license may be detrimental to the health, safety, and welfare of the residents served by the life support agency or applicant, the department may issue a nonrenewable conditional license effective for not more than 1 year and may prescribe such conditions as the department determines to be necessary to protect the public health, safety, and welfare.
