As a professional engineer (PE) in California, it is crucial to understand the requirements for using PE stamps on your official documents and drawings. The use of PE stamps is regulated by the California Board for Professional Engineers, Land Surveyors, and Geologists (BPELSG) to ensure the authenticity and accountability of engineering work. In this blog post, we will summarize the key requirements for California PE stamps.

  • BPC Section 6735.3: Signing and sealing of electrical engineering documents
  • BPC Section 6735.4: Signing and sealing of mechanical engineering documents
  • CCR Section 411: Seal and Signature

  2. Electronic Signatures: The use of electronic signatures and digital seals is permitted, provided they meet the requirements set forth by the BPELSG.
  3. Out-of-State Licensees: PEs licensed in other states must obtain a California PE license to practice engineering in California and use the California PE stamp on their documents.
  4. Stamp Ownership: The PE stamp is the property of the licensee and must be under their control. It is the licensee’s responsibility to prevent unauthorized use of their stamp.

By adhering to these requirements, California PEs can ensure compliance with state regulations and maintain the integrity of their professional work. It is essential to stay informed about any updates or changes to the California PE stamp requirements by regularly reviewing the BPC and CCR sections mentioned above.
