What Buildings Department does

Buildings Department (屋宇署) is the statutory building safety regulator of the Hong Kong Special Administrative Region Government, operating under the Buildings Ordinance since 1993 and headquartered at North Tower, West Kowloon Government Offices, 11 Hoi Ting Road, Yau Ma Tei, Kowloon. The Department enforces building and construction safety across Hong Kong's private building stock, administers the Mandatory Building Inspection Scheme (MBIS) and Mandatory Window Inspection Scheme (MWIS), processes and approves building plan submissions, maintains registers of Authorized Persons, Registered Structural Engineers, Registered Geotechnical Engineers, Registered Inspectors, and registered contractors, and prosecutes unauthorised building works and dangerous structures. Its three primary user segments are property owners / owners' corporations, building professionals, and registered building contractors.

The Department operates a layered digital platform portfolio. The Electronic Submission Hub (ESH), rolled out in three stages (March 2022, March 2023, June 2024), is the mandatory channel for plan and document submission. BRAVO provides public access to building records; the Registered Minor Works Management System (RMWMS) and the Licensing Self-certification Portal (LSCP) handle contractor registration and licensing workflows. BIM Automated Checking Tools automate plan-review checks for sanitary fitments, fire safety, and structural compatibility. Public-facing tools include Registers Search, Authorized Signatory Search, Orders Search, and the MBIS/MWIS Notices and Fire Safety Directions Search. The 'Ah Build' chatbot, deployed circa 2020, uses NLP and machine learning to handle MBIS/MWIS enquiries in Traditional Chinese, Simplified Chinese, and English. Mobile delivery includes the WIN SAFE app for the Mandatory Window Inspection Scheme. Service delivery is supported by a walk-in enquiry counter, the 1823 government hotline (24/7), and an online E-Learning Centre.

Buildings Department does not operate a commercial revenue model; services are statutory public functions funded through the Hong Kong SAR Government budget and the Department is accountable to the Development Bureau. As a government agency it is not publicly traded and has no parent company in the corporate sense. Distribution is direct through government counters, digital self-serve portals, and the 1823 call centre, with awareness and outreach via an official website, Facebook, Instagram, YouTube, and thematic publicity campaigns such as the Building Safety Pioneer Programme 2026. The Department also partners with the Construction Industry Council to administer the Technically Competent Persons Registration Scheme (TCPRS) and operates a Signboard Validation Scheme with signboard data published to the Government's GeoInfo Map.
