Using your seal/stamp

The following rules apply to all work you prepare or supervise:

    • Technical submissions required for building permits, regulatory approvals, or construction drawings filed with authorities having jurisdiction.
    • Drawings prepared by you (on each sheet).
    • Specifications and other technical submissions (on the cover, title page, and all pages of the table of contents).
  • Your seal/stamp must include your signature and license expiration date. Your signature can be handwritten or a digitally-represented handwritten version and must be next to the stamp/seal. (Requirements may differ in local jurisdictions.)
  • If you use preprinted identification block tracing sheets, you may have the seal/stamp printed on the block at the time of manufacture. You must add your signature and expiration date to each sheet before they’re printed.
  • If you seal or stamp documents you have reviewed, you’re responsible to the same extent as if you had prepared them yourself.
  • You may use more than 1 seal/stamp on drawings and specifications, but it’s not necessary.

You may not use your seal/stamp:

  • If your license is one of the following:
    • Expired
    • Delinquent
    • Revoked
    • Suspended
  • On any drawings not prepared by you or your regularly employed subordinates, or not reviewed by you.
