 ## Enforcing a policy for changes to repository visibility
 
 Across all organizations owned by your enterprise, you can allow members with admin access to change a repository's visibility, restrict repository visibility changes to organization owners, or allow owners to administer the setting on the organization level. When you prevent members from changing repository visibility, only enterprise owners can change the visibility of a repository.
