Who is responsible for black mold from the AC unit?« Back to Previous Page

Under Dubai rental law, the landlord is typically responsible for maintaining the structural integrity of the property and its fixed systems, including the AC unit and its condensate drainage. Since the mold originates from the AC unit's condensation point, this is generally considered a maintenance issue falling under the landlord's obligation.

You should formally notify your landlord in writing immediately, including clear photos of the mold and its location relative to the AC. The high humidity here accelerates mold growth from any condensation leak, making prompt action critical. For a patch described as "huge and spreading," a professional inspection is strongly advised to assess the moisture source and potential health risks. A certified mold inspector can document the cause and required remediation scope, which strengthens your case with the landlord.

If the landlord disputes responsibility or fails to act, you can file a complaint with the Rental Dispute Center (RDC) in Dubai. Keep all communication and any professional reports as evidence. Do not attempt to remove it yourself, as improper handling can disperse spores and worsen the problem. The remediation must address the moisture source—likely a blocked drain line or faulty insulation—not just the visible mold.
