However, one change in particular is causing a fair number of questions and will require some adjusting in the industry.
Shifting from Seismic Zones to Peak Ground Acceleration

Under the old PNA guide a property would require a seismic risk assessment if it was located in Seismic Zone 3 or 4, and exhibited one or more of seven (7) documented structural or site hazards. As of this moment, Freddie Mac and CMBS lenders will still rely on the seismic zone map to determine the seismicity of the property, though there is some debate whether this change will carry across the industry at some point.
