It's not parted. It's the partitions themselves (or more accurately,
the devices via which your operating system makes the partitions
available to user space). By default (and there are some reasons
for it) they're not readable by everyone. They are writable by
even less. On my box, for example:

  tomas@rasputin:~$ ls -al /dev/sd*
  brw-rw---- 1 root disk 8, 0 Nov  7 09:06 /dev/sda
  brw-rw---- 1 root disk 8, 1 Nov  7 09:06 /dev/sda1
  brw-rw---- 1 root disk 8, 2 Nov  7 09:06 /dev/sda2
  brw-rw---- 1 root disk 8, 5 Nov  7 09:06 /dev/sda5

So you'd have to be associated to the "disk" group to read those
things and you'd have to *be* root to write.

Same goes for lsblk (as has been recommended in this thread) or
any other tool you might consider. That said, lsblk seems to be
a better fit for your needs anyway.

Parted has no problems running as a regular user if the (device)
file under question is (readable/writable) by said user. It only
tries to be helpful with some messages when it isn't running under
root *and* encounters permission/owner conflicts. *That* might
cause some confusion.
