Breaking a lease because of no Egress window on 3rd floor bedroom

[Jeremy Mullin]

Not sure if this is the right place to put this question. I have a college town rental property and added an egress window to a basement bedroom- the additional bedroom is worth about $650/month so it's a no brainer.  Morally, I'd never want a kid living in a room that he couldn't get out of if there was a fire, legally I'm certain I wouldn't want that either. Unfortunately I don't think safety come in to every landlord's mind, which brings me to my question.  My son is living in a 3rd floor room of a college house (different campus than mine) and has two triangle shaped windows in his room, 28" x 28" so no where near the required egress area of 5.7 cu ft (although he could fit through them if he had a step stool to get to them).  I'm fairly certain knowing what I know now that the landlord should not be renting that room out to tenants. Does anyone have any opinions on if something like this (as well as no emergency ladder to escape-although we ended up buying him one for our piece of mind) is grounds for breaking a lease?  As a landlord, I'm not too interested in hurting a small business guy doing exactly what I'm doing. As a father, I'll do what I can to make sure my son lives in a safe place and isn't penalized financially for trying to attain that.
