The answer is very simple: superstition. The number 13 is considered to be unlucky and is omitted for that reason in buildings.
Superstitious beliefs include the belief that the number 13 is unlucky (or that any number is unlucky), that it is unlucky to walk under a ladder, or pretty much any belief about what things are lucky or unlucky; there is a very odd belief prevalent among actors that it is unlucky to mention the name of the play "MacBeth" which is therefore referred to as the Scottish play. That is a superstition.
mostly superstition because it is supposed to be an unlucky number
There is no direct reference in the Bible that suggests the number 13 is unlucky. The number 13 is considered unlucky in some cultures due to its association with the Last Supper where Judas, the betrayer of Jesus, was the 13th guest. It is a superstition, not a biblical teaching.
In most Anglo-Saxon cultural communities including the UK, Canada and the United States, the number 13 is considered as an unlucky number.
