Great question. I have been wondering the same thing. We have a stamp here that has been used long before I ever got here, and I've often thought that it could (or maybe should) include a bit more language. I'll be very interested to see what others have. Maybe I can make a suggestion to the higher ups for some improvement. Ours reads:
This permit is issued only with the understanding that the design, calculations, load, and forces pertaining to this building are complying with the _______ California Building Code.
Permit No. ________________

I was thinking it might be beneficial to add either this direct quote from code, or a summary of this:
Validity of Permit

The issuance of a permit based on construction documents and other data shall not prevent the building official from requiring the correction of errors in the construction documents and other data.
