According to wikipedia, here are some possible reasons why many people in the US consider the number thirteen to be unlucky:
Friday the 13th has been considered an unlucky day since the 1800s, as a combination between an unlucky day, Friday, and the number 13. Another theory as to why the date and number 13 is considered unlucky is that, on the day of Friday the 13th after the final Crusade the pope had sent out men to capture and burn alive the last 13Â Knights Templar in order to put an end to the Crusades.
A second theory links the bad luck associated with the number 13 with Jesus Christ’s last supper where the persons around the table, counting the Christ and the twelve apostles, was, indeed, thirteen. This would also be the reason why it is considered unlucky to have 13 guests at a table.
Another theory states that the number 13 is unlucky because, when in years where there were 13 full moons instead of 12, it made it difficult for the monks who were in charge of the calendars. “This was considered a very unfortunate circumstance, especially by the monks who had charge of the calendar of thirteen months for that year, and it upset the regular arrangement of church festivals. For this reason thirteen came to be considered an unlucky number.”
Whatever the reason, we decided to take some pictures of high-rise elevators we’ve been in since we decided this would be a cool post.

Post International, 1388 Gough St.
The Post International gets around the “problem” of having a 13th floor by labeling it the Penthouse level. Way to dodge the issue, Post International!

The Infinity
Notice anything missing at The Infinity? Why yes, they seem to have forgotten to build a 13th floor!

One Rincon Hill
The builders/developers/designers/architects (who makes this decision anyway?) at One Rincon Hill apparently have no concern for the triskaidekaphobic among us.
So there you have it, three very different approaches to dealing with the sticky issue of what to call your 13th floor. We know we didn’t have time to get pictures of a bunch of high rise buildings in SF so we’d love it if you left a comment and let us know how they handle it in your building?
