My HDB neighbor's water leak damages my flat. How do I claim compensation in Singapore?

What the Law Says

Under Singapore law, a neighbor whose faulty plumbing, poor maintenance, or negligent renovation causes water leakage into your flat may be held liable in tort for negligence or private nuisance. Section 3(1) of the Civil Law Act (Cap. 43) codifies the common law duty of care: if your neighbor’s act or omission foreseeably causes physical damage to your property, they may be liable for repair costs and consequential losses. The Protection from Harassment Act (Cap. 256A) does not apply to accidental leaks but may be relevant if repeated failures to rectify constitute intentional harassment. Importantly, HDB’s lease conditions (under the Housing and Development Act, Cap. 129) require flat owners to maintain their premises in good repair and not cause nuisance to others — breach may support a claim even without proof of negligence.

Practical Steps

Immediately after discovering the leak, take dated photographs/videos of affected areas, retain receipts for temporary repairs (e.g., dehumidifiers, emergency drying), and obtain a written report from a licensed plumber identifying the source and cause. Notify your neighbor and HDB’s Branch Office in writing (email + registered post) within 48 hours, citing the nature of damage and requesting urgent remediation. Next, file a free mediation request with the Community Mediation Centre (CMC) — over 80% of such disputes resolve at this stage. If mediation fails and your claim is ≤$20,000, file online via the SCT e-Filing system within 6 years; for larger claims, consult a lawyer to commence action in the District Court. Keep all correspondence, invoices, and CMC outcome letters as evidence.
