Your HOA will need a board of directors, which typically includes a president, vice-president, secretary, and treasurer. Elections will need to be held in the community for these roles.
HOA meetings are also important. All homeowners and residents can attend, and board members will need to be prepared, organized, and open, with an agenda and an assigned person to keep minutes of the meeting. Learn the parliamentary procedures for meetings, and create a summary with action steps at the end of the meeting.
