In Chicago, code requires EMT for all electrical, which can be annoying for adding a new run, but at the very least it makes it less likely for rodents to chew through or other interference.

After wiring my whole house with Ethernet and ceiling speakers, and now dealing with a couple leaky pipes and several problems from previous owners, I'm considering ways to make these things easily accessible/replaceable while keeping an eye toward aesthetics.

For nearly a decade, Chicago does allow MC cable in a number of circumstances, basically up to 25 feet branches where you don’t want to open up a wall.
