The condo building I used to live in (in Toronto) was built in 2003 and had no 4th, 13th or 14th floor, nor did it have units #4, #13 or #14 on each floor; it just skipped from 3 to 5 and from 12 to 15. So I ostensibly lived in unit 2016, but on the actual deed it was listed as unit 1713.
(The number “4” is unlucky in some areas of Asia since it sounds similar to the word for “death”. I guess “14” was unlucky because it had a 4 in it?)
