WILMINGTON, Del. — Wilmington’s city council has voted unanimously to lower the mayoral age requirement from 30 to 25, bringing it more in line with age requirements for other elective offices in Delaware.

Despite the council’s vote Thursday night, the proposed change in the city’s charter still needs approval by the General Assembly.

City officials say the current age requirement could be problematic if a mayor resigns or dies in office. In such an instance, the city council president takes the mayor’s place. But the minimum age for serving on city council is 25, meaning the council president might be unable to meet the age requirement for mayor.

Wilmington’s current age mayoral requirement is higher than the age requirements for state lawmakers and for mayoral candidates in Georgetown and Dover.
