Despite widespread regulations against smoking in public, apartment buildings and condos tend to be rather lax when it comes to rules against cigarette consumption. Traditionally, the idea has been that you can do whatever you want behind closed doors, even if smoke travels from unit to unit.

That's not, however, the case at Alto, an eight-storey building on Dundas West that's advertised as the city's first non-smoking apartment building. The prohibition of smoking here is so serious that the building manager tells the Star that "legal action would be taken" were someone to break the rules.

Smoking has been prohibited in common areas of apartments and condos for over a decade, but the vast majority of residential buildings are toothless when it comes to in-unit smoking bans. Alto also features green initiatives in the form of shared bikes and electricity from low impact sources like wind turbines, but it's the no smoking rules that make the building unique.

What do you think? Should more residential buildings go smoke-free?
