Pedant time! "5-over-1" doesn't refer to five floors of residential over one floor of retail, but any configuration of timber stick construction (IBC Type 5) over a concrete podium (IBC Type 1). Thus, you can have a 5-over-1 that's only 4 stories, or a 5-over-1 that's all residential, etc.

- sokoloff 5y agoThat was very informative pedantry; thanks!
- kevinburke 5y agoCorrect, but the law at issue is specifically about housing needs, so you’d need to build apartments in this case, you couldn’t build commercial.
- lotsofpulp 5y agoWikipedia says the proliferation of these 4 and 5 stories of wood construction above 1 story of steel/masonry happened because of a 2009 revision to the International Building Code. If that is true, then it would seem like one plus five, one plus four, 5 over 1, and 4 over 1 buildings would refer to how many wood floors the building has above the first floor. https://en.wikipedia.org/wiki/5-over-1 https://en.wikipedia.org/wiki/5-over-1 I do not know how good the source is for Wikipedia, but I have only ever seen 5 and 6 story buildings, and never 7 or more stories with the first floor having masonry/steel and then wood for the rest.
- brendoelfrendo 5y agoYou are correct that these buildings were only made possible due to changes in the code as to how many timber stories you could build, and the max is 5 stories. But my point was that they're not called that because they're 5 stories.
