By default, all organization members can create repositories. If you restrict repository creation permissions to organization owners, and your organization was created under the legacy organization permissions structure, members of legacy admin teams will still be able to create repositories.
Legacy admin teams are teams that were created with the admin permission level under the legacy organization permissions structure. Members of these teams were able to create repositories for the organization, and we've preserved this ability in the improved organization permissions structure.
You can remove this ability by migrating your legacy admin teams to the improved organization permissions.
For more information, see "Repository roles for an organization."
Warning: If your organization has disabled repository creation permissions for all members, some members of legacy admin teams may lose repository creation permissions. If your organization has enabled member repository creation, migrating legacy admin teams to improved organization permissions will not affect team members' ability to create repositories.
