SingaporeWhat are the penalties for unauthorised renovation in HDB?
Unauthorised renovation in HDB flats can result in a fine of up to $5,000 and/or prosecution under the Housing and Development Act. HDB may also require reinstatement of the flat to its original condition.
What the Law Says
The Housing and Development Act gives HDB the authority to regulate renovations in flats it owns or manages. Section 56 specifically prohibits unauthorised alterations and empowers HDB to enforce compliance.
Under Singapore law, all HDB flat owners must obtain prior approval from HDB before carrying out certain types of renovation work — especially structural changes, removal of walls, or modifications affecting fire safety, plumbing, or electrical systems.
Carrying out unauthorised renovation is an offence under section 56 of the Housing and Development Act. If found guilty, the owner or occupier may be fined up to $5,000. HDB may also issue a written order requiring the flat to be reinstated to its original condition.
This applies regardless of whether the renovation was done by the owner, tenant, or contractor — the flat owner remains legally responsible.
Statutory TextAny person who, without the prior written approval of the Board, carries out any alteration, addition or demolition in respect of any building or part thereof which is owned or managed by the Board shall be guilty of an offence and shall be liable on conviction to a fine not exceeding $5,000.
— Housing and Development Act, s. 56 — Unauthorised alteration, addition or demolition
What to Do
Check HDB’s list of approved renovation works and determine if your planned work requires prior approval.
Submit a renovation application via HDB’s e-Service or at an HDB branch before starting any work.
Engage only HDB-registered renovation contractors for controlled works.
Keep all approval letters and inspection reports on file.
If HDB issues a reinstatement order, comply promptly to avoid further penalties.
