Is landlord responsible for AC leak and mold?« Back to Previous Page

The AC in my apartment seems to be leaking a little water into the closet in our second bedroom, and now we’ve discovered a patch of black mold on the back wall. It’s been getting worse over the hot season. Who is responsible for fixing this and the cost of cleaning, us as tenants or the landlord?

Based on UAE tenancy law, specifically Law No. (26) of 2007, landlords are generally responsible for maintaining the structural integrity of the property, which includes the maintenance of major building systems like air conditioning. An AC unit leaking water is a maintenance issue, and the resulting mold growth is a direct consequence of that failure.

The landlord's responsibility is to provide a habitable property. Persistent moisture from an AC leak that leads to mold infestation falls under this obligation. You should formally notify your landlord or property management company in writing about the issue immediately, as delays can exacerbate the mold growth and potential health risks. They are typically responsible for arranging and covering the cost of the repair to the AC unit and the subsequent mold remediation to restore the property to a habitable condition.

However, it is critical to determine the root cause. In Dubai's climate, with high humidity and year-round AC use, condensation issues are common but often point to inadequate maintenance of the AC drip pan, clogged drain lines, or insufficient insulation. The black mold you describe indicates a persistent moisture problem.

For a definitive assessment and to protect your interests, we strongly recommend a professional mold inspection. Our certified experts at Saniservice can conduct a comprehensive assessment to identify the exact species of mold, the extent of contamination, and the precise source of the moisture. This provides an official report that can be used to ensure the landlord addresses the issue correctly and completely.
