When assigning VLANs in an office building, do the IP addresses I assign to said VLANs HAVE to match the VLAN's number?

For example, say I have a certain department in this office building assigned to VLAN 10. This department has the network address 10.1.1.0 and the usable address range is 10.1.1.1 – 10.1.1.127. Would this work for this VLAN, or should I have something along the lines of 10.1.10.0 for the network address for this VLAN?

Your choice of IP address ranges can be arbitrary, but it is customary to use addresses in the private address space. With IPv4 these are addresses in the ranges 10.0.0.0 – 10.255.255.255, 172.16.0.0 – 172.31.255.255, and 192.168.0.0 – 192.168.255.255.

There's no relationship between a number you use to refer to a certain VLAN and the addresses in that VLAN. Take a look at this answer about the relationship between IP address ranges (subnets) and VLANs.
