Who is responsible for mold from a leaking AC unit?« Back to Previous Page

In the UAE, the responsibility for mold remediation stemming from a leaking AC unit is primarily determined by the source of the leak and the tenancy contract, specifically Law No. (26) of 2007 Regulating the Relationship between Landlords and Tenants in the Emirate of Dubai.

The landlord is unequivocally responsible for the structural integrity of the property and the maintenance of its core systems. This includes the central AC system, the main chilled water supply lines (if applicable), and the drainage pipes within the building's walls. If the leak originates from a failed pipe, a faulty condensation drain pan within the AC unit itself, or a clogged primary drain line, the repair and subsequent mold remediation fall under the landlord's obligation.

However, tenant responsibility is typically limited to the maintenance of appliances they have installed and the general upkeep of the property. Annual servicing of an AC unit is a crucial tenant responsibility; it primarily involves cleaning filters and the evaporator coil to maintain efficiency. Crucially, this servicing should include checking and clearing the condensate drain line. If the leak is a direct result of a completely blocked drain line that was not addressed during routine tenant maintenance, this could be argued as tenant negligence.

Given the high humidity and year-round AC use in Dubai, condensation is a constant battle. The black mold you describe indicates a persistent moisture issue. To definitively determine liability, a professional inspection is essential. A certified mold assessor, like those at Saniservice, can identify the exact source of the moisture intrusion and provide a detailed report. This technical report is your strongest evidence in any discussion with the landlord or the Dubai Rental Dispute Center.
