That’s probably what they mean by plumbing. They just don’t know how to describe it.
But telling someone they can’t smoke in their own home?! Ludicrous. Is the smoke going to penetrate the wall and blow in the wind through your neighbor’s drafts? Please.
It does waft. Doesn't penetrate the walls, of course. But it does waft. Again: personal experience supports me.
It's obvious I'm highly ambivalent about this issue, but I'm not trying to be devil's advocate or argue for the sake of argument. The truth is that smoking is a landlord's nightmare. On one side you've smokers complaining about regulations impinging into their rights and freedoms (understandable: it's
their home, even if it's rented); on the other you have non-smokers complaining about lack of regulations or enforcement impinging into their right to 'clean' and/or odourless air (also understandable: it's
their home, even if it's rented). No matter which side wins, the landlord always loses. Beyond the issues of conflict among tenants, there're also issues of property damage and property value and appeal. Let's face it: most smokers are cigarette smokers (in the US, only about 2% of all smokers are pipe smokers): cigarette smoke is pungent, pervasive, and the tars and residues of cigarette combustion stain the walls—landlords have to end up paying for all that damage: they don't want to. I don't blame them.
The first apartment I rented had as its previous tenants a smoking couple. No amount of washing, deodorising, carpet deep-cleaning was ever able to get the smell out. I eventually left after living there less than 2 months (smoke stench wasn't the only reason I moved, mind). Landlords have a hard time renting such units, specially in an age when vast amounts of the population have been frightened to death about all kinds of cancers from tobacco products, and when the rental market is at a historical low.
