Target Buildings under Mandatory Building Inspection Scheme (MBIS) and Mandatory Window Inspection Scheme (MWIS)
with statutory MBIS/MWIS Notices served by the Buildings Department
Windows, if not properly used, or lack of maintenance and repair, may dislodge, or even fall from buildings and cause serious consequences.
To ensure public safety, building owners are advised to acquaint themselves with the proper ways of using, maintaining and repairing their windows.
The building works associated with construction, alteration, repair or removal of windows must be carried out in accordance with the requirements of the Buildings Ordinance (BO).
Under the Mandatory Window Inspection Scheme (MWIS), owners of buildings aged 10 years or above (except domestic buildings not exceeding 3 storeys) and served with statutory notices are required to appoint a Qualified Person (QP) to carry out the prescribed inspection and supervise the prescribed repair works found necessary of all windows of the building.
Where a prescribed repair is required, the owners concerned must appoint a registered contractor to carry out the prescribed repair under the supervision of a QP.
