Who is responsible for mold on a damp exterior wall?« Back to Previous Page

Mold on a damp exterior wall is typically the landlord's responsibility to repair, as it stems from a structural or building envelope issue. In Dubai, tenancy laws generally hold the property owner accountable for maintaining the structural integrity of the apartment, which includes fixing leaks and addressing moisture penetration from outside.

Since you mention the wall is exterior and the issue began after heavy dehumidification, the cause is likely condensation due to the significant temperature differential between the cool, air-conditioned interior and the hot, humid exterior climate. This is a common building physics problem in the UAE. The landlord should address the source of the dampness, which may involve improving wall insulation or repairing a hidden leak.

Your responsibility as a tenant is typically to report the issue in writing to the landlord or property management company immediately. Document the damage with clear photographs and a detailed description. You must also take steps to prevent further moisture accumulation, such as ensuring the room is well-ventilated and that the AC is functioning correctly to manage humidity levels.

For a case this severe, a professional inspection is crucial to determine the exact moisture source and the full extent of the mold growth, which may be inside the wall cavity. A certified mold assessment can provide a documented report on the cause, which is essential evidence if you need to formally dispute responsibility with the landlord. In many cases, remediation cannot begin until the underlying moisture issue is permanently resolved by the property owner.
