In late 2009, both Hinsdale and Clarendon Hills began to explore the possibility of sharing various Village services. Village Board members and Staff started to explore sharing services between each Village's Fire Departments and in August of 2010, each Village entered into an Intergovernmental Agreement to share Fire and EMS services. While this is not a consolidation of the Departments into one Fire Department, it is an agreement to share services, personnel, equipment, apparatus, support vehicles, and ambulances for the delivery of services to both communities.

The current agreement calls for each Village to provide a dedicated number of personnel on duty to provide services - six located in the Village of Hinsdale and three located in the Village of Clarendon Hills and includes consolidated dispatch services, standardized responses to emergency incidents in each community, standardized policies, procedures, equipment and apparatus, and a common fee structure for both Fire Prevention and Inspection Services and ambulance transportation.

Members of each Fire Department jointly training in not only fire, rescue, and EMS topics but are conducting walk-through and pre-incident surveys in various commercial properties in both Villages like UChicago Medicine Advent Health Hinsdale Hospital, RML Specialty Hospital, the Office Park of Hinsdale, The Birches Assisted Living Center, and all the schools and churches.
