Mandatory Building and Window Inspection Scheme (MBIS/MWIS)

Introduction of MBIS and MWIS

MBIS
Under the MBIS, owners of buildings aged 30 years or above (except domestic buildings not exceeding 3 storeys) and served with statutory notices are required to appoint an Registered Inspector (RI) to carry out the prescribed inspection and supervise the prescribed repair works found necessary of the common parts, external walls and projections or signboards of the buildings.

Where a prescribed repair is required, the owners concerned must appoint a registered contractor to carry out the prescribed repair under the supervision of an RI.

MWIS
Under the 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.
