Is landlord responsible for black mold by AC vent?« Back to Previous Page

Under Dubai rental law, the landlord is typically responsible for repairs related to the building's structure and essential services, which includes the central AC system and the building envelope. Since the mold originates from the AC vent—a fixture they are responsible for maintaining—and the ceiling, this is likely their obligation to fix.

The pattern you describe, especially worsening after high humidity, points to a condensation issue. This is common in Dubai where AC systems work year-round and can create significant temperature differentials between cold ducts and the humid air, leading to moisture accumulation inside walls. The problem isn't just the visible patch; the underlying moisture source must be addressed to prevent recurrence.

You should formally notify your landlord or property management company in writing, including clear photos. Request a professional mold inspection to identify the moisture source and assess the extent. A proper remediation involves fixing the condensation leak, repairing any water-damaged materials, and cleaning the AC ductwork.

While you wait for a response, keep the area well-ventilated and avoid disturbing the mold, as this can release spores. Do not attempt to paint over it or use bleach, as this will not solve the underlying moisture problem and can mislead a professional assessment. If the landlord is unresponsive, you can reference your rights under Law No. 26 of 2007 Regulating the Relationship between Landlords and Tenants in the Emirate of Dubai and may need to escalate through the Dubai Land Department's Rental Dispute Center.
