Oh, been meaning to add somewhere:
If the apartment buildings owner bans it then that's their right, renters are not the ones responsible in an apartment building therefore we do have fewer rights, however, it MUST be in the lease, if not then the owner has no right to set arbitrary rules whenever they feel like because the renter did not agree to them in the contract. Reasons for banning smoking though are rarely about the health of residents ... it's the cleaning cost. The cost to clean one apartment after a year of smoking was almost $500 ten years ago, not sure what it is today but with the increase of other costs I imagine it's much higher. Most security/cleaning deposits are much less in buildings that ban smoking, as are rents, so it has a benefit to the smoker to live in such a place. Mine does allow smoking, thankfully, but is also rent controlled, again thankfully. Though I wouldn't complain if they wanted to add it in the lease, I am renting a great place for less than half what closet space costs in other buildings in this city. There is a way to work around those if you have the money and a good reputation with the owner, you offer to pay more in rent or deposit.
