I’ve been turned down for rentals because I smoke and because I was single, separately.
I think I have a right to smoke and be single.
Smoking isn’t a right and can damage the units. (Not that I’m against smoking - all for it).
Not renting because youre single is illegal though
I lived in an apartment where my neighbors in an adjoining apartment smoked. My apartment was unlivable because of it, because I tried everything to keep the cigarette smoke out of my apartment. Nothing worked. My landlord had to let me out of my lease.
You have a right to be left alone to smoke...but the property owner has the right to not rent to people who will cause excessive damage to their property - especially by coating the entire contents with a noxious substance, including spaces occupied by others - or to charge said people for mitigation...or not.
Where things go seriously off the rails is where the government makes that choice for the property owners.
