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.
