Romex in Chimney chase Multi family?

A friend of mine in Los Angeles tells me that you have to sleeve romex in a fire place chase multi family. We were talking Low rise multi family where NM is allowed. The assumption is this is a fire rated area.

Are you talking about the space behind a prefab fireplace? If so I would disagree with them.
