The Mecklenburg Board of County Commissioners serves as the Mecklenburg Board of Health, Board of Social Services, and Board of Mental Health.  Mecklenburg County and Wake County are the only North Carolina counties which share these designations due mostly to their large size. This change from separate oversight boards was made possible by a North Carolina law that allowed local boards of county commissioners to consolidate the boards of health, social service, and mental health under their one entity.  This was an attractive and logical option for large, urban, growing counties where services for residents were broad and required consolidate funding and oversight.

The Mecklenburg Board of County Commissioners serves as the Board of Health which provides funding for health services at the Health Department locations, reviews and approves Health Department regulations and laws, and acts as an advisory board elected by the citizens of Mecklenburg County.
