Things are different here in Portugal. No tenant would forbid you to smoke in your own home ("His" house, "his" property, but "your" home, since you are the one paying the rent to live there, and thus have the right to make yourself at "home", within the law).
And that happens because the tenant, not the landlord, can be forced to pay for those replacements himself. Many times, it does not happen, on a MUTUAL agreement between them, if the situation is not all that bad. Otherwise, the tenant is required to pay for those repairs himself before he leaves, because he is supposed to leave the house just as it was before. So, many smokers have the privilege to smoke in "their" home sweet homes, but knowing that someday they *might* have to spend some money to cover the costs of said privilege.
So, in my country, the very notion of a landlord forbidding tenants from smoking in "their own" homes, is already strange. Forbidding vaping?? Simply ridiculous. Just how would they inforce that? Where is the tell-tale smell? The darkening of the painting on the walls? The holes in the carpet? All those lasting, visible reasons that will keep non-smokers at bay?
Above all, where is the real EXCUSE for that, besides the sick need of sticking their noses in other people's PRIVATE lives ?? Do those tenants really find it so difficult to rent a house to non-smokers, after NON-smoking VAPERS have lived there ??
