Who is responsible for black mold from AC in rental?« Back to Previous Page

Under Dubai rental law (Law No. 26 of 2007), the landlord is generally responsible for maintaining the property's structure and essential services, including the central air conditioning system and its components like ducts and vents. The presence of black mold originating from the AC unit or its condensation system typically falls under their obligation to provide a habitable premises.

However, the argument about thermostat settings is a common point of contention. While running the AC can help manage indoor humidity, a properly functioning system should not cause significant condensation and mold growth at 24°C, which is a standard and reasonable temperature. The issue is likely a fault in the AC's drainage system, insufficient insulation on cold water pipes, or leaky ducts, all of which are structural maintenance items.

Your first step is to formally notify your landlord in writing (email is best), detailing the issue with clear photographs of the mold and referencing the damp smell. Clearly state that the problem appears to stem from the AC system. For serious, visible growth, a professional inspection and lab testing can definitively identify the moisture source and mold type, providing a documented report that strengthens your case. In Dubai's high humidity, hidden condensation within walls or under slabs is common and requires expert diagnosis.

If the landlord refuses to act, you can file a complaint with the Rental Disputes Center (RDC) in Dubai. They will often side with the tenant if the problem is proven to be due to a maintenance issue with the property itself. Do not attempt to remediate extensive mold yourself, as improper handling can spread spores and exacerbate the problem.
