No - shared multi owner properties here in BC are referred to as Condominiums or Strata properties.
So when I refer to strata units, I mean those sort of properties.
Of course any such sound related rules are only applicable to units where people have units below them.
The fire safety criteria is only encountered in buildings that have been designed with very high end fire suppression materials and features. That happens sometimes when developers decide to make such features a marketing feature, because those features can provide a long term benefit arising from reduced shred insurance premiums.
Savings on shared insurance costs are often the reasons why multi-unit buildings will have rules prohibiting bar-be-ques or mandating metal clad washer hoses and a bunch of other similar restrictions or requirements.
When one considers buying into such a building, one needs to read those rules first before signing the offer.
A fair number of stratas are now being built with, or bringing in changes to the rules to, prohibit smoking or vaping anywhere in the building, including within individual units. That is a real sales feature for more and more people. Generally existing smokers are grandfathered in the buildings that pass the change.
On the actual topic of the thread, I'm pretty quiet about the fact that I do darkroom work in our unit, because I don't want any of the neighbours to think that I am doing something that they think, because they don't understand it, should be against the rules.
