Before you can transform your flat to your dream home, take a look at our guidelines and conditions on the Do's and Don’ts of renovation and electrical works. This service package provides all the renovation/electrical information you need to know so that your renovation can proceed smoothly.

Renovation Works Not Allowed

HDB regulates the types of renovation works that are carried out in HDB flats. All renovation works have to be carried out by HDB Registered Renovation Contractors (RRCs). Certain types of renovation works need a permit from HDB before they are allowed to be carried out.

However, some renovation works are not allowed to be carried out due to the following reasons:

Overloading the structure which may affect the structural integrity and safety of the building.
Affecting the external facade/form of the building or public safety.
Creating public nuisance, posing fire hazard or encroachment to public area.
Infringing lease agreement, relevant statutory regulations or requirements, etc.

Examples of Renovation Works Not Allowed

Hacking and removal of structural members such as reinforced concrete wall, columns, beams, slabs, staircases within maisonette flats, etc.

Excessive overloading of the floor slab with a load greater than 150 kg for every metre square of floor area.

Plastering of ceilings.

Partitioning with combustible or toxic emission materials (e.g. plywood, plastics, asbestos etc.)
