I have a question regarding heated vs non heated structures. If a home is required to maintain 64 degrees what happens if there is a power outage or if it becomes a vacation home and isn’t heated in the winter? I understand that if you remove 1 of the 3 situations for ground freezing it wouldn’t be an issue, but is that a safe bet? Isn’t a safer bet to build all fpsf as an unheated space to avoid risks?
