I’m in a literal remote position being in Alaska, our weather is very different, our building codes different and we are different because we are used to handling what is happening in the lower 48.
My house actually has a outside entry door hanging up out in the open on my second floor, it opens to space, it was put in just in the event of heavy snow, never had to use it though, the people who built the house were from England. However a bit south around Valdez and Whittier you would need to that on not just the 2nd floor but a 3rd story as well, they really get that much snow, over 85’!
Our building principles in the ‘Burgh are a little different.
Primarily based on graft, bribes, corruption and organized crime labor. When put to the test sometimes they fail.
