How does a DHCP server connect to a subnet?
So you can either configure relay agent (ip helper) on router interfaces connected to your new networks or connect DHCP server to each new subnet directly using additional NICs on DHCP server. Since you mention that there will be routing between all subnets, then you need to configure IP helper address on router interfaces to point to DHCP server.

How does DHCP server work with different VLANs?
Different devices on different VLANs, each VLAN with an IP helper/Relay Agent address of DHCP server, which has a different scope for each VLAN, thereby devices on each VLAN get an IP address from the appropriate scope, because IP helper/Relay Agent tells DHCP server the IP address of the VLAN the request came from. Is that about right?

What are the scopes of a DHCP server?
So if your DHCP server has two network interfaces lets say A & B, and each interface is in a different subnet. DHCP has two scopes, Scope_A and Scope_B, and these match the subnet of the interface then a request from a device received by interface A will get an address from Scope_A, and the same is true from Scope_B.
How does DHCP respond to an IP address?
Part of MS standard DHCP offering is that it will respond with an IP address from a scope, based on the interface that receives the DHCP request. So if your DHCP server has two network interfaces lets say A & B, and each interface is in a different subnet.
