Upstairs Unit Leaking Into Yours?
Inter-Floor Leakage Rules in Malaysia (2026)

The Strata Management Act 2013 and Regulations 2015 create a clear framework — including a rebuttable presumption against the upper-floor owner — for resolving inter-floor leakage disputes in Malaysian strata buildings.

Under the Strata Management (Maintenance & Management) Regulations 2015, inter-floor leakage is presumed to originate from the upper parcel unless the upper-floor owner proves otherwise. The management body (JMB or MC) must inspect within 7 days, issue a Form 28 certificate within 5 days of inspection, and direct the responsible party to repair. If management is unresponsive, you can escalate to the Commissioner of Buildings (COB) or the Strata Management Tribunal (claims up to RM250,000).

This guide is for general information only — not legal advice. Confirm your specific situation with the COB, Strata Management Tribunal, or a qualified Malaysian property lawyer.

What counts as inter-floor leakage?

Under Regulation 55 of the Strata Management (Maintenance & Management) Regulations 2015 (Source: Strata Management (Maintenance & Management) Regulations 2015, P.U.(A) 107/2015), inter-floor leakage is defined as evidence of dampness, moisture or water penetration on the ceiling, or any material attached, glued, laid or applied to the ceiling — including plaster, panel and gypsum board — which forms part of the interior of a parcel, accessory parcel or common property.

In plain terms: if your ceiling shows water stains, damp patches, paint bubbling, or actual dripping water originating from the floor above, you have a Regulation 55 inter-floor leakage situation and the formal framework kicks in automatically.

Two instruments govern inter-floor leakage in Malaysian strata buildings (Source: Strata Management Act 2013 (Act 757); Strata Management (Maintenance & Management) Regulations 2015):

  • Strata Management Act 2013 (Act 757), ss. 21 & 59 — impose a statutory duty on both the Joint Management Body (JMB) and the Management Corporation (MC) to maintain common property in a state of good and serviceable repair.
  • Regulations 55–67 of the Strata Management (Maintenance & Management) Regulations 2015 — set out the specific definition, notice procedures, inspection timelines, Form 28 certificate, four-rule liability framework, and escalation pathway for inter-floor leakage and party wall damage.

This framework applies to all strata buildings in Peninsular Malaysia and the Federal Territories governed by Act 757, whether managed by a JMB (before strata title is issued) or an MC (after strata title).

The rebuttable presumption explained

The most important rule in the Regulations 2015 is the rebuttable presumption: unless proven otherwise, the defect causing inter-floor leakage is presumed to be within the parcel above the affected parcel (Source: Strata Management (Maintenance & Management) Regulations 2015, Reg. 58; MahWengKwai & Associates, FAQ on Inter-Floor Leakage & Party Wall Damage in Strata Schemes, Mondaq 2022).

What this means practically:

  • The burden of proof shifts to the upper-floor owner. It is not your job to prove the upstairs unit caused the leak — they must disprove the presumption.
  • The upper-floor owner can rebut the presumption by demonstrating the leak originates from common property (e.g. a shared pipe serving multiple units, a roof membrane, or a structural crack) — in which case management bears responsibility.
  • If the leaking infrastructure serves only one unit (e.g. a bathroom pipe inside the upper unit), that unit’s owner is responsible regardless.

Who pays — liability decision matrix

The Regulations set out four rules for determining liability (Source: Strata Management (Maintenance & Management) Regulations 2015, Regs. 58–62; Yew Huoi, How & Associates, Inter-Floor Leakage):

ScenarioWho is responsibleBasis
Leak originates from infrastructure serving more than one unit (shared pipe, water meter, gas duct, drainage serving multiple parcels)JMB / MC — common property defectCommon property definition under SMA 2013
Leak originates from infrastructure serving one unit only (internal bathroom pipe, private floor trap, internal waterproofing failure)Owner of the upper parcelIndividual parcel maintenance duty
Cause cannot be determined after inspectionRebuttable presumption → upper parcel owner, unless they rebutReg. 58 presumption
Leak originates from roof or external structureJMB / MC — common propertyRoof is common property under SMA 2013
Building still under developer maintenance period (typically 24 months from VP)Developer under Housing Development (Control & Licensing) Act 1966 or SMA 2013 transition rulesDeveloper’s duty during maintenance period

Step-by-step: from notice to repair

Follow this sequence to use the Regulations 2015 framework correctly:

  • Step 1 — Written notice to management. Give written notice (letter or email) to your JMB or MC identifying your unit, describing the leakage and the affected ceiling area, and requesting an inspection under Regulation 56. Keep a copy with the date.
  • Step 2 — Management inspection (7-day deadline). Management must inspect within 7 days of your notice (Regulation 57). They inspect your unit, the upper unit (with that owner’s cooperation), and the relevant common property.
  • Step 3 — Form 28 issued (5-day deadline). Within 5 days of the inspection, management must issue a Form 28 Certificate of Inspection naming the cause and the responsible party (Regulation 57(5)).
  • Step 4 — Rectification directed. Management directs the responsible party to carry out repairs within a stated period. If the upper-floor owner is responsible, management issues a written direction to them.
  • Step 5 — If repair not done. Escalate to the COB (Regulation 63) or file at the Strata Management Tribunal.

Form 28: the inspection certificate

Form 28 — the Certificate of Inspection of Inter-Floor Leakage / Damage to a Party Wall — is a prescribed form under the Regulations 2015 (Source: Strata Management (Maintenance & Management) Regulations 2015 — Form 28; JMBMALAYSIA.ORG, Form 28 Certificate of Inspection for JMB & MC). It is the key document in any leakage dispute because it:

  • Officially records the cause of the leakage as determined by inspection.
  • Names the party responsible for rectifying the defect.
  • Forms the evidential basis for any COB referral or Tribunal claim.

If management refuses or fails to issue Form 28 within the 5-day deadline, that itself is a breach of the Regulations and grounds for a COB complaint. You should note the date of your inspection request and follow up in writing if Form 28 has not been issued within the prescribed time.

Evidence to gather

Strong documentation protects your position whether the matter is resolved informally or escalates to the Tribunal:

  • Photographs and video of the ceiling stains, damp patches, or active dripping, dated and time-stamped.
  • Written notice to management — sent by email or WhatsApp so the date is logged; keep all replies.
  • Form 28 once issued — request a copy immediately.
  • Repair quotations from licensed contractors for ceiling repair, repainting, and any damaged furniture or fittings.
  • Plumber’s report if you engage one independently to identify the source (useful if management is slow).
  • Receipts for emergency or interim repairs (e.g. dehumidifier rental, protective sheeting) — these can be claimed back.

Escalating to the Commissioner of Buildings (COB)

The Commissioner of Buildings (COB) is the regulatory authority attached to the local council (DBKL, MBPJ, MBSJ, etc.) responsible for enforcing the SMA 2013 (Source: Strata Management Act 2013 (Act 757), Part I; KPKT — Ministry of Housing and Local Government). If you are dissatisfied with management’s Form 28 determination, or if management has failed to inspect, issue Form 28, or direct repairs within the prescribed timelines, you may file a written complaint with the COB under Regulation 63.

The COB can:

  • Conduct its own independent determination of the cause and responsible party.
  • Issue directions to management, the upper-floor owner, or the developer to carry out repairs.
  • Impose fines for non-compliance (Source: Strata Management Act 2013, enforcement provisions).

COB complaints are free. Contact the COB unit at your local city or municipal council. Bring your written notice, the Form 28 (if issued), photographs, and any correspondence.

Strata Management Tribunal claim

The Strata Management Tribunal (SMT) is a quasi-judicial body under KPKT (Ministry of Housing and Local Government) that hears strata disputes without the cost and delay of civil court (Source: SMA 2013, Fourth Schedule; MahWengKwai & Associates, 10 Things to Know About the Strata Management Tribunal). For inter-floor leakage, the SMT can:

  • Order the upper-floor owner or management to carry out repairs.
  • Award compensation for loss and damage (ceiling, furniture, renovation costs).
  • Handle claims up to RM250,000.

Penalties for non-compliance

Failure to rectify inter-floor leakage after a direction from management, the COB or the Tribunal carries real legal consequences. Under the SMA 2013 and Regulations 2015, an owner who fails to comply with a rectification direction may face fines and, in serious cases, imprisonment (Source: Shang & Co, Failure to Rectify Inter-Floor Leakage May Be Liable to Fine and Jail; SMA 2013 enforcement provisions). A Tribunal award that is not satisfied can be enforced as a civil court judgment — including through seizure of property.

If the upper-floor owner’s actions amount to continuing nuisance or trespass, you may also have a civil claim under Malaysian tort law. A landlord who is aware of nuisance caused by their tenant but takes no steps to stop it can also be held liable (Source: Yew Huoi, How & Associates, Strata Title — Trespass and Nuisance).

Prevention tips

  • When renovating your bathroom or wet areas, engage a licensed contractor and ensure proper waterproofing membrane with a written warranty — poor DIY waterproofing is the most common cause of leaks to the floor below.
  • Inspect visible pipes under kitchen and bathroom sinks regularly for slow drips — a small drip can saturate the slab over months before becoming visible below.
  • If you are the lower-floor owner, document and report any new damp patches to management promptly in writing — delays weaken your claim.
  • When buying a strata unit, inspect the ceiling carefully and ask the seller for any leakage history or Form 28 certificates — latent leakage problems should affect the purchase price.

Common Questions

Who is responsible for inter-floor leakage in Malaysia?
Under the Strata Management (Maintenance & Management) Regulations 2015, leakage is presumed to originate from the upper parcel unless that owner proves otherwise. If the leak comes from common property (a shared pipe, roof, etc.), the JMB or MC is responsible. The management body must inspect and issue a Form 28 certificate to formally determine responsibility (Source: Strata Management (Maintenance & Management) Regulations 2015, Regs. 55–62).
What is the rebuttable presumption for inter-floor leakage?
Regulation 58 of the Strata Management (Maintenance & Management) Regulations 2015 creates a legal presumption that the defect causing the leak is within the parcel above the affected unit. The upper-floor owner must rebut this by proving the leak originates elsewhere, such as from common property or a shared infrastructure.
What is Form 28 in the context of inter-floor leakage?
Form 28 is the prescribed Certificate of Inspection of Inter-Floor Leakage under the Strata Management (Maintenance & Management) Regulations 2015. The JMB or MC must issue it within 5 days of inspection, stating the cause of the leak and the party responsible for rectification. It is the key document for any escalation to the COB or Tribunal.
How long does management have to respond to an inter-floor leakage complaint?
Management must carry out an inspection within 7 days of receiving your written notice (Regulation 57), and issue the Form 28 certificate within 5 days of that inspection. If they miss these deadlines, you can file a complaint with the Commissioner of Buildings (COB).
What can I do if the upstairs owner refuses to repair the leak?
File a written complaint with the Commissioner of Buildings (COB) of your local council, or file a claim at the Strata Management Tribunal (strata.my). The Tribunal can order repairs and award compensation up to RM250,000. Non-compliance with a Tribunal award is enforceable as a civil court judgment.
Can I claim compensation for damaged furniture and renovations from inter-floor leakage?
Yes. The Strata Management Tribunal can award compensation for loss and damage, including damaged furniture, ceiling repairs, and repainting costs. Document all damage with photographs and obtain repair quotations from licensed contractors before the hearing.
What if the leak is from common property, not the upstairs unit?
If the inspection (Form 28) determines the leakage originates from infrastructure serving more than one unit — such as a shared drainage pipe, water meter, or the roof — it is a common property defect. The JMB or MC is then responsible for carrying out and funding the repair under SMA 2013, ss. 21 and 59.
What if I am a tenant — can I still report inter-floor leakage?
Tenants can report the issue to the landlord and request they notify management in writing. The Strata Management Tribunal’s jurisdiction is primarily for owners, purchasers, JMBs and MCs. Tenants with a lease may also have a contractual claim against their landlord if the habitable condition of the unit is affected by the unresolved leakage.
