USPAP’s FAQs Adress Electronic Report and Workfile Storage
In the 2012-2013 edition of USPAP, two Frequently Asked Questions (#92 and #93) address issues relating to electronic storage.
FAQ #92. Electronic workfile storage
Question: Recently I have considered maintaining only electronic workfiles (i.e., saving only electronic versions of my reports and supporting data, and scanning any paper documents used so that copies may be stored on electronic media). Is this prohibited by USPAP?
Response: No. There is nothing in USPAP that would prohibit an appraiser from maintaining only electronic versions of workfiles.
