Hello, good morning.

1. I have a non-admin user (that means the [ ] Administrator checkbox is not set)
2. I have assigned that user a Role having the Create subproject permission.
3. Then the user creates its own subproject.

Question:
How can that user later delete the subproject he just created ?

I don’t see a user interface option for that.

In Projects-> View all projects there is no delete option, as I see.

Thanks.

You can go to admin/projects and you have delete buttons there.
