Black mold near AC: landlord or tenant responsibility?« Back to Previous Page

Under Dubai rental law, the landlord is typically responsible for structural repairs and issues arising from building defects, including water infiltration and faulty AC systems that cause mold. Since the mold is spreading from the corner near the AC unit, the source is likely a hidden leak in the pipework or condensation drain, or a breach in the building envelope—all structural issues.

Constant AC use in Dubai's humid climate is actually the correct action to reduce indoor humidity, not the cause. Mold growth in this location strongly suggests an underlying moisture problem the tenant cannot control. Document the spread with dated photos and formally notify the landlord in writing, requesting a professional inspection to identify the moisture source.

Do not attempt to clean it yourself, as disturbing it can spread spores. The underlying leak must be fixed first; otherwise, the mold will return. A proper remediation involves identifying the species, fixing the water source, containing the area during removal, and verifying clearance with post-remediation testing. If the landlord refuses, you can file a complaint with the Rental Dispute Center (RDC) in Dubai.
