The executive authority of Norfolk County is vested in the board of County Commissioners. Similar to a Select Board, the County Commissioners oversee budget, policy and other decisions to be carried out by the Norfolk County Commissioners Office, including county purchasing and personnel offices. County Commissioners are ex officio members of the Board of Norfolk Agricultural High School. They oversee a $33.5 million budget and oversee programs that include Registry of Deeds, Norfolk Agricultural High School, Wollaston Recreational Facility, County Treasury Office, Retired and Senior Volunteer Programs, County Engineering Department, trial court facilities management, appellate tax jurisdiction and open space management. The three Commissioners are elected for four-year terms, with only one permitted from any one city or town. Revenue for Norfolk County comes from a share of taxes from communities, Registry of Deeds receipts, and reimbursement for court facilities.
