Just about every rental I ever lived in was non-smoking, even houses. It's either that, or you replace the carpet/paint the walls with every new tenant, which just isn't cost-effective. I was an outside only smoker anyway for most of my smoking life, so it wasn't a big deal. And yeah, sometimes I broke the rules if it was super cold outside, but otherwise not. I have a rental property now, and no, my tenants are not allowed to smoke inside. They can go outside, onto the nice porch, just like I did when it was the house that I lived in. I'm sure they break the rules sometimes
which is fine, just as long as it's not 24/7 making the place reek or burning giant holes in the carpet.
I am all for doing whatever you want to do within your own home, and I know that it sucks to be a smoker who wants to smoke inside who can't because of the rental agreement
because I lived that reality for most of my life as a smoker, even after I purchased my own home (because by then, I was used to doing it outside and didn't want to stink the inside up with it). But landlords are landlords because they need to make money, not friends unfortunately. I do think apartment complexes that don't allow smoking in outside spaces are idiotic, and would never live in one or agree to those lease terms ever. And banning
vaping is pretty dumb, because it in no way damages the property.
That is why I said the OP should just ask. I can't imagine that they're including vaping in the sense that we mean it. It doesn't hurt the apartment. No point in suffering needlessly, or wondering and worrying, just get clarification and move on from there.
