Who is responsible for black mold from hidden AC leak?« Back to Previous Page

Landlords are typically responsible for repairs to the property's structure and fixed systems, including the AC and its condensate drain lines, which are the most common source of hidden leaks. The Dubai Rental Law (Law No. 26 of 2007) generally places the obligation on the landlord to maintain the property in a habitable condition.

Your use of a dehumidifier is a strong point in your favor, as it demonstrates proactive measures to control the ambient humidity common in Dubai's climate. Mold growth from a concealed AC leak is a building envelope issue, not a tenant-caused ventilation problem. The initial step is to formally notify your landlord in writing, detailing the issue and requesting immediate remediation to prevent further structural damage.

For a case of this size, a professional inspection is critical to determine the exact moisture source and full extent of the mold. The inspection report will serve as vital evidence. It should include moisture mapping and, if necessary, surface or air samples analyzed by an accredited microbiology lab to identify the species, which can clarify the severity.

If the landlord refuses to acknowledge responsibility, you can file a complaint with the Rental Dispute Center (RDC) in Dubai. They will assess the evidence, including any professional reports, to determine liability for the mold removal and necessary wall repairs.
