Are we or the landlord responsible for black mold?« Back to Previous Page

Responsibility depends on the cause. In Dubai rentals, the landlord is typically responsible for repairs due to structural issues, like a hidden water leak from a pipe in the wall or a faulty AC condensation drain line. The tenant is usually responsible for damage resulting from their own actions or negligence, such as failing to ventilate a room properly.

Given your description—a large patch spreading behind furniture and worsening with AC use—a hidden leak is the most probable cause. The constant AC operation in our humid climate creates significant condensation; if the drain line is blocked or the unit is improperly insulated, that moisture gets trapped inside walls.

Your first step is to formally notify your landlord or property management company in writing, with photos. They are obligated to investigate the source of the moisture. Do not attempt to clean it yourself, as disturbing significant black mold can release a high concentration of spores. A professional inspection is needed to identify the exact species and, more importantly, locate and fix the water source. Without fixing the leak, the mold will return quickly.

For verification, you can reference RERA's rental laws, which stipulate the landlord must maintain the property's structure and essential systems. Since your husband is experiencing health effects, emphasize the urgency in your communication. A reputable inspection with lab identification can provide definitive evidence linking the mold growth to the building's water intrusion, which strengthens your case for the landlord to cover the full remediation cost.
