Vent for stove necessary in rental home?

[Cameron Price]

I'm getting ready to rent out a propery I rennovated. It has no vent/ hood over the stove. Is a hood necessarry? 

It doesnt have a exhaust fan in the bathroom either.  I 'm at the property as I post this to figure out what I need to do to add the exhaust fan in the bathroom to keep from dealing with mold issues. Is it the same type of thing in the kitchen?
