Summary

MHL Consulting reviewed and stamped eight electrical sheets (E01 to E08) from a combined mechanical, electrical and plumbing plan set for a California SB 9 and accessory dwelling unit project. The set came through a referral, and MHL returned the stamped electrical sheets the day after receiving a readable file.

Problem / Objective

The project’s lead engineer needed a California-licensed electrical PE to review and stamp the electrical sheets so the plan set could move forward.

Process

  1. Received the request through a referral partner on January 5, 2026, covering electrical, mechanical and plumbing sheets.

  2. Scoped the MHL portion to the eight electrical sheets (E01 to E08).

  3. Asked for a resend when the attachment did not come through.

  4. Reviewed the electrical sheets on receipt of the file.

  5. Stamped and signed the electrical sheets and returned the PDF on January 6, 2026.

Payoff / Results (Metrics)

  • Eight electrical sheets reviewed and stamped in one business day from a readable file

  • Referral relationship carried the work, with the client confirming receipt

  • Electrical stamp added without disturbing the other disciplines’ sheets

When this applies

An engineer, designer or builder in California with an SB 9 lot split or accessory dwelling unit plan set that needs a licensed California electrical PE stamp on the electrical sheets, with the other disciplines handled by someone else.
