Just looking to settle an argument. Isn’t the intent of Section 1. (Bldg. Code:) intended to use the A. and B. answers ONLY for homes outside the HVHZ and built 2001 and later or built 94 or later and inside the HVHZ?
With that in mind , all homes outside HVHZ and built prior to 2001 would be checked as C. Unknown or does not meet the requirements of A or B.
