According to CTV news – “The city of Vancouver has issued a bulletin requiring developers to abstain from omitting certain floor numbers from new buildings in an effort to simplify the work of first responders. In short, the days of skipping ‘unlucky’ numbers such as 4 and 13 are numbered.
As of Oct. 20, the city requires all new buildings to follow a consecutive, increasing number system for floor and suite lettering. Simply put: you can’t skip any numbers
Existing buildings that have avoided a traditional numbering system may be required to change numbers on a case-by-case basis.
Certain buildings across Vancouver have omitted the number four or 13 from floors and suites as part of a cultural trend against “bad luck.”
Thirteen has been long considered an unlucky number in Western culture. There’s even a phobia called triskaidekaphobia where sufferers will avoid any use of 13.
In Chinese culture, the number four is considered unlucky due to its pronunciation sounding similar to “death.”
“Four, 13 any other number people want to skip for whatever reason, we’re putting back in and basically putting a normal mathematical sequence of numbers into a building design,” said Pat Ryan, the city’s chief building officer
