HDB Resale Flat Defect and Condition Disclosure Singapore 2026

HDB Resale: The "As Is" Principle

HDB resale flats are sold in their current condition. Unlike new HDB BTO flats, resale flats come without a developer's defect liability period and without warranties on fixtures and fittings beyond what the seller provides. The buyer is generally expected to inspect the flat and make their own assessment of its condition before exercising the OTP.

This "as is" principle does not, however, mean that sellers and their agents can conceal known defects. Concealing material defects from a buyer is misrepresentation — a breach of CEA obligations for the seller's agent and potentially actionable at law by the buyer.

What the Seller's Agent Must Disclose

Under CEA's Code of Ethics and Professional Client Care, the seller's agent must not actively misrepresent the property and must disclose material facts known to them. For HDB resale flats, material facts that require disclosure include:

• Known structural defects — spalling concrete, significant wall cracks, subsidence or settlement issues that the seller has knowledge of
• Persistent water leakage — inter-floor leakage from the unit above, or leakage into the flat from external sources, that has been present during the seller's occupation
• Pest infestations — known termite or pest infestations that have not been fully treated
• Death on the premises — deaths that occurred in the flat during the seller's occupation. In Singapore, many buyers have cultural sensitivities about this. Some sellers disclose voluntarily; in some circumstances the seller's agent may be obliged to disclose if directly asked
• Unauthorised renovations — works carried out without HDB approval that HDB may require to be reinstated. If the seller knows of such works, the agent should advise disclosure as the buyer may inherit the reinstatement obligation
• Neighbouring disputes — ongoing disputes with neighbours that have been formally raised (e.g., with the HDB or Community Mediation Centre) that would materially affect the buyer's quiet enjoyment
• HDB compliance issues — outstanding HDB notices or infringements relating to the flat

HDB's Role in the Resale Process

HDB does not conduct a condition inspection of resale flats on the buyer's behalf. HDB's role in the resale process is administrative: verifying eligibility, processing the application, and facilitating completion. HDB does check for:

• Unauthorised renovations — HDB conducts an inspection as part of the resale process to check for renovations that were not HDB-approved. If found, HDB may require the seller to reinstate before the sale proceeds.
• Illegal subletting — HDB checks whether the flat was being used in accordance with HDB rules (e.g., not as a short-term rental)
• Outstanding arrears — HDB loan arrears, S&CC arrears, and property tax arrears are cleared at completion

HDB's inspection is not a defect inspection. Buyers should not assume that HDB's approval of the resale transaction means the flat is in good condition.

What Buyers Should Check at Viewing

Before exercising the OTP, buyers and their agents should conduct a thorough viewing. Key items to check in an HDB flat:

Walls and Ceilings

• Yellowish or brownish staining on ceilings (inter-floor water leakage from the unit above — a common problem in older HDB blocks)
• Significant cracks — particularly diagonal cracks at window and door corners, or cracks that appear to have been repeatedly patched
• Mould patches or musty smell — indicates persistent dampness or poor ventilation
• Fresh paint on specific patches (rather than the whole flat) — may indicate an attempt to conceal staining or damage

Floors

• Hollow tiles — tap floors; a hollow sound indicates de-bonded tiles that will need to be removed and replaced
• Buckled or warped laminate flooring — typically caused by water damage or inadequate subfloor preparation
• Uneven floors — may indicate settlement or structural movement

Plumbing and Water

• Run all taps and flush all toilets — check water pressure and drainage
• Check under sinks for evidence of previous leaks or repairs
• Look for water staining at the base of walls in bathrooms and the kitchen, which can indicate persistent seepage

Electrical

• Check the distribution board — confirm it is not overloaded and that breakers are labelled
• Test light switches and power points throughout the flat
• For older flats, ask whether the electrical wiring has been updated

Renovation and Compliance

• Ask the seller or agent whether all renovations were HDB-approved. Specific items to look for: hacking of walls, converted rooms, kitchen hob mounted on a hacked wall, enclosed service yard
• Check whether the flat layout matches the original HDB floor plan — any deviations may represent unauthorised works

Defects Discovered After Completion

Once the buyer has exercised the OTP and completed the purchase, their options for defects discovered after completion are significantly more limited:

• Latent defects fraudulently concealed — if the seller or the seller's agent actively concealed a known defect (e.g., painted over active mould before the sale), the buyer may have a claim for misrepresentation. This is difficult to prove and requires legal action.
• Patent defects visible at inspection — defects that were visible and should have been apparent to a reasonable buyer during inspection are generally the buyer's problem. The seller is not typically liable for defects the buyer could have discovered and chose not to investigate.
• HDB warranty on structural elements — HDB provides a 15-year structural warranty on BTO flats from the date of purchase. This does not apply to resale flats in the same way.

For post-completion disputes about concealed defects, the buyer's recourse is typically through the courts. Legal action is expensive, time-consuming, and uncertain. Prevention — through thorough pre-OTP inspection — is far more practical.

The Seller's Agent's Role in Disclosure

The seller's agent faces a tension between the seller's interest in maximising the sale price and the obligation not to misrepresent the property. Practically speaking:

• The agent should advise the seller to disclose known material defects proactively — concealment carries legal and CEA risk and typically reduces rather than increases the final outcome when discovered during negotiation
• The agent should ensure that photographs and listing descriptions do not create a false impression of the flat's condition
• If the seller refuses to disclose a defect that the agent considers material, the agent should consider whether to continue acting for that seller
• The agent should encourage the seller to resolve known defects (e.g., repair a water leak) before listing where practical — a flat in better condition attracts better offers
