Inspection
Mandatory inspection under the MBIS is required for all common parts (except the areas within individual private premises), external walls (whether or not the external walls are common parts), projections as prescribed in the Building (Inspection & Repair) Regulation(B(I&R)R) and signboards erected on a building.
The Code of Practice for the Mandatory Building Inspection Scheme (MBIS) and the Mandatory Window Inspection Scheme (MWIS) 2012 (2023 Edition) specifies the technical and procedural requirements for the carrying out of the building inspection, examination or assessment, rectification and repair works under MBIS. It also provides for the scope and requirements of inspection, rectification and repair works as well as the acceptance criteria for quality control.
For examples of the building elements within the scope of prescribed inspection for MBIS, please refer to Annex I under General Guidelines for Mandatory Building Inspection Scheme & Mandatory Window Inspection Scheme.
