Are we liable for black mold on exterior wall?« Back to Previous Page

Based on the details you've provided, this scenario is a common issue in Dubai's climate, particularly in buildings with continuous air conditioning. The black spots are highly indicative of a mold colony, likely caused by thermal bridging and condensation on the exterior wall. The constant cooling of the interior wall surface by the AC, contrasted with the extreme outdoor heat, creates a cold spot where moisture from the humid air condenses. This trapped moisture behind the wardrobe, with limited air circulation, provides the perfect environment for mold growth.

Under UAE tenancy law, specifically Law No. (26) of 2007, the responsibility for structural and exterior wall maintenance typically falls on the landlord. Since the issue is related to the building's envelope and its interaction with the climate, it is not considered damage caused by tenant misuse. Your obligation as a tenant is to report this issue to the landlord or property management company immediately and in writing, prior to your lease renewal. This formal notification is crucial for establishing that the problem existed during your tenancy and protects you from liability for the damage.

However, a professional inspection is essential to determine the exact cause, extent of the infestation, and any potential hidden damage within the wall cavity. The remediation process must address the root cause—the condensation—not just the visible mold, to prevent rapid recurrence.

For a definitive assessment and to ensure your rights are protected, I strongly recommend you contact our specialists at Saniservice. We can provide a comprehensive inspection report that details the cause and scope of the issue, which is often required for discussions with landlords.
