Definition
A voting threshold higher than a simple majority — such as two-thirds or 75% — required for major decisions like amending the CC&Rs.
A supermajority is a required approval level above a simple 50%-plus-one majority — commonly two-thirds or three-quarters. Governing documents reserve supermajorities for consequential actions.
Typical examples include amending the CC&Rs, approving large special assessments, or making significant changes to common property. Supermajority requirements protect the community from major changes being pushed through by a slim margin, but they also make such changes harder to achieve.
