In general, the Licensing Office of the Food and Environmental Hygiene Department (FEHD) will refer revised plans at the licence application stage or alteration plans of licensed restaurants to the Buildings Department (BD) for comment if such plans consist of changes related to building safety. With the launch of a new Self-certification System by BD in December 2019, for restaurant licence applications/alteration applications processed and verified to have met certain criteria by BD, the applicant may opt to join the System by submitting an Authorized Person (AP)'s certification to FEHD to certify that the proposed changes shown on the revised plan/alteration plan are in compliance with the building safety requirements. Upon receipt of the AP's certification, FEHD will continue to process the application without the need of referring such plans to BD for comment.
You are welcome to visit the BD's website (https://www.bd.gov.hk/en/about-us/our-services/licensing-advisory-services/index.html) for details of the System.
