What if I hacked my room before selling my unit at 157 Jalan Teck Whye?

If you hack or demolish any part of your HDB flat (such as walls or floors), you must obtain prior approval and a renovation permit from HDB before starting the work. Hacking of structural walls, columns, or important structural elements is strictly prohibited as it can endanger the building’s safety and affect your neighbours. Only non-structural partitions may be considered for removal, and all such works must be submitted through an HDB-registered renovation contractor for official assessment and approval.

Renovation works, especially hacking, are tightly regulated in Singapore to maintain the safety, structural integrity, and harmony of public housing. Unauthorized hacking risks serious consequences, including hefty fines, mandatory reinstatement, and even legal prosecution.

Always:
- Engage only HDB-registered renovation contractors who are familiar with compliance requirements.
- Apply for the relevant HDB renovation permit.
- Await formal approval before commencing any hacking works.

Commonly allowed works (with approval) include removing non-structural partition walls, installing new flooring, and reconfiguring interior spaces—provided they do not affect the building’s structure. Prohibited works include hacking load-bearing or structural walls, changing the façade, and relocating bathrooms or sewage systems.

Before starting any renovation, always consult the latest HDB guidelines and work with authorized professionals to avoid penalties and ensure your flat remains safe and legally compliant.
