Re: Smoking ban inside your condo - Bylaw passed Depending how the building was constructed, there may be air pressure issues in the building which 'pump' smoke from one unit/floor to another.
I've seen this issue in a condo building a friend of mine lives in. People in the penthouses have wood-burning fireplaces and when they fire them up, the smoke smell seeps down the halls and down 3-4 floors into individual units. These fireplaces vent through the roof - a good 50' above affected units.
The smell 'migration' occurs in all types of weather - so it's not related to wind direction or temperature inversion conditions, which was a principle contributor to the great 'pea soup' killer fogs of London, England.
Whether it's cigarette or wood smoke, or even paint/chemical odours, these can all cause problems for people with allergies living floors away from the source.
