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

Based on UAE rental law, specifically Law No. (26) of 2007, the responsibility for structural repairs to the property, including walls and fixed installations like the AC unit's housing and condensate drain lines, falls upon the landlord. The tenant is typically responsible for internal maintenance of appliances.

In your case, the leak is causing damage to the wall structure. Even with annual servicing, the issue could be a blocked or damaged condensate drain pipe within the wall, a faulty installation, or poor insulation around the unit—all of which are structural elements the landlord is obligated to maintain. The resulting black mold is a direct consequence of this water intrusion. The landlord's argument is unlikely to hold under the law, as the tenant's maintenance obligation pertains to the AC's filter and internal mechanics, not the building's infrastructure.

Given the presence of a "huge patch" of black mold, a professional inspection is critical. In Dubai's high humidity, mold spores can proliferate rapidly behind walls, posing health risks and compromising structural integrity. A certified mold assessment from a company like Saniservice will identify the exact moisture source, map the full extent of contamination, and provide a definitive report that can be used to formally notify the landlord of their responsibility.

Do not attempt to remediate this yourself. Disturbing extensive mold without proper containment can spread spores throughout your apartment. For a professional inspection and a detailed report to present to your landlord, you should call 800-MOLDS (800-66537) or email hello@saniservice.com. They can document the cause and provide a scope for the necessary remediation and repairs.
