Expiration Date No Longer Needed on California PE Stamps

California law was changed regarding professional engineering (PE) stamps. On October 11, 2009 Governor Schwarzenegger signed AB 645 (Niello) eliminating the requirement to show expiration dates on PE stamps. The seal must continue to show name, number, and discipline, but the "Exp." line in the middle is no longer required. The minimum diameter of the seal remains at 1.5 inches. The bill was passed to avoid holding up projects for replotting and restamping of plans due to a license being renewed prior to construction.
