The first and foremost reason for smoke-free housing is clean indoor air.

If second-hand smoke respected boundaries and stayed where tobacco was smoked, we wouldn’t have people calling and emailing us every week with complaints of involuntary exposure in their own homes.

Due to differences in air pressure between units, between floors and between the inside and outside of a building, air (and second-hand smoke) can transfer through a variety of leakage paths:

  • from a neighbour’s patio or balcony, or from outdoor common areas;
  • through open windows or doors;
  • through electrical outlets, cable or phone jacks, or ceiling fixtures;
  • through cracks and gaps around sinks, countertops, windows, doors, floors, walls or dropped ceilings; and
  • through the ventilation or forced air system.

Research has shown that up to 65% of the air in a unit can come from other units in the building.

Here’s a great video illustrating how smoke travels due to the stack effect.
