If the mold growth, like the patch behind your wardrobe, is a result of a pre-existing building defect—such as water seepage from a leaking pipe in the wall, a faulty external sealant allowing moisture ingress, or inadequate insulation leading to condensation—then the remediation cost and repairs fall squarely on the landlord. The persistent high humidity and year-round AC use in Dubai can exacerbate these underlying issues, making them a building failure, not a tenant-caused problem.

However, the tenant is responsible for damages resulting from their own negligence. This would include scenarios like failing to use the provided ventilation systems, causing excessive internal moisture through activities without proper exhaust, or failing to report a minor leak in a timely manner, allowing mold to proliferate.

Given that the mold has appeared and spread significantly, a professional inspection is absolutely critical. A certified mold inspector can conduct moisture mapping and air quality testing to definitively identify the source of the moisture. This technical report is essential evidence to determine liability. Self-remediation is strongly discouraged, as improper handling can aerosolize spores, creating a greater health risk and potentially causing more extensive contamination.
