(NB: I haven't use DHCP since I switched to BSD, but...)
man dhclient:
The -1 flag cause dhclient to try once to get a lease. If
it fails, dhclient exits with exit code two.
I assume it should work even if the client already has a lease. You might also check /sbin/dhclient-script: it should get
called with $reason = RENEW whenever the DHCP lease gets renewed normally, so you should be able to just duplicate that.
Possibly even call it directly, but I'd read the man pages & script(s) carefully first.
