I should add that I've also tried these flags:

rsync --super -o -g --perms -z --partial -v --recursive --stats
--times --links --exclude-from=${LOCAL_DIR}/.rsync-EXCLUDE
--timeout=1800 ${LOCAL_DIR} ${REMOTE_LOGIN}:${REMOTE_DIR}

but get errors such as
rsync: chown // failed: Operation not
permitted (1)

-o is the option you want, but the receiving rsync needs to run as root
to be able to set the file ownership. Alternatively, you could use
--fake-super, which does not set the real ownership but saves the
ownership data in an extended attribute from which a later rsync run can
retrieve it.

So would the receiving end need to be running in daemon mode? There
would be no way to set the proper ownership if it isn't?

Not necessarily. The receiving end just needs to run as root, and that
can be accomplished on a run over remote shell by logging into the
remote root account directly or using "sudo" or similar.
