    If the user vlan has a L2 connection all the way to the DHCP server, it will work. Bootprelay is only needed if the DHCP server is on a different vlan than the users.

    The only other reason would be that there is a DHCP server on that VLAN that you are not aware of such as a wireless router added incorrectly or someone added a server but as Brad has stated, if the L2 connection to the DHCP server then addresses will be available to the end clients
