We’ve just added a by-law at the AGM last month pretty much to that effect, but did not include BBQs:
“An Owner or occupier of a Lot must not smoke cigarettes, cigars or pipes whilst they are on Common Property, including but not limited to the entry foyer and lobby, or allow smoke from their Lot to enter Common Property.”
The logic was to go for the common property first, as one of the major problems was a rear light-well/fire stair which is great for a fresh breeze when the back door is open, but is an obvious choice for the smokers too, and also the assumption that any smoke entering private property “passes through common property”, which I think is a bit weak personally.
We were a bit wary of going for any laws affecting private property, but I personally hope to make the whole building non-smoking in time, especially seeing quote’s like ”If you can smell smoke, it is hurting you”. If this is true, then it would be more than a nuisance, it would surely be a HAZARD !!
(I am a balcony BBQer by the way, but since reading here about the cigarette issue etc. I’d like to think I’m a bit more considerate now. And I will happily give that up if there is a decision to do so. But I don’t know that BBQ is the same health issue as cigarette smoke.)
