MBIS

After receiving statutory notices, owners of buildings at least 30 years old (except domestic buildings not exceeding three storeys) are required to appoint a Registered Inspector (RI) to carry out the prescribed inspection and supervise any prescribed repair works found necessary to the common parts, external walls and projections or signboards of the buildings. After a notice (the preceding notice) has been complied with, the owner will not receive another notice in respect of the same part of the building within 10 years.

The inspection must cover the following building elements:

• External elements and other physical elements;
• Structural elements;
• Fire safety elements;
• Drainage systems; and
• Identification of unauthorized building works (UBWs) in the common parts of the building, on the exterior other than the common parts of the building (such as external wall, roof or podium, yard or slope adjoining the building), or on the street on which the building fronts or abuts.
