My home as a kid did. I don't know why it's fallen out of favor, since I can't imagine it costing more than $100 or so in parts and labor on a build... If we can have a bathroom vent, why not a cooking vent?

If the vent moves more than a certain amount of CFM air, then an exchange system is required, but that takes almost a restaurant grade vent to get to.
