I have seen info in other forums, but did not see anything in here.
From the best I can find, NFPA does not specify a required safety margin. In general, we have required 5% in the past but do not have anything in our ordinances that actually require it. I have seen from web searched that some jurisdictions require 10%. Just a general discussion point, not necessarily a question, what are others using as a safety margin and how have you required compliance in the past.
