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

The AC in our Deira apartment has been leaking a little bit for a while, and now we've found a patch of black mold spreading on the wall behind the bedroom curtain. Our landlord is saying it's our fault for not reporting the AC issue sooner, but we only just noticed the leak was that bad. Who is legally responsible for the mold removal and fixing the wall in this situation?

In the UAE, the legal responsibility for mold remediation stemming from a leaking AC unit is typically governed by the tenancy contract and Dubai Law No. 26 of 2007, as amended (the Dubai Rental Law). The core principle is the distinction between maintenance and misuse.

The landlord is generally responsible for the structural integrity of the property and the maintenance of major installed systems, including the central AC unit and its associated drainage lines. A persistent leak is a maintenance issue that falls under their obligation to provide a habitable dwelling. If the leak is the direct and sole cause of the mold growth, the landlord is legally responsible for repairing the AC, addressing the resultant mold contamination, and restoring the damaged wall.

However, the tenant has a duty to report any issues in a timely manner. The landlord's argument hinges on the concept of tenant negligence. If you were aware of the leak for an extended period and failed to report it, thereby allowing the damage to escalate, you could be held partially liable for the resulting damage. Since you "only just noticed the leak was that bad," your position is strong, provided you can demonstrate you reported it promptly upon discovery of the significant mold.

Given the high humidity and constant AC use in Dubai, minor condensation can quickly escalate into a major mold problem. This situation requires professional assessment. The mold behind the curtain indicates a sustained moisture issue. A certified inspector can determine the full extent of the infestation, identify the exact source of the moisture, and provide a detailed report that can be used to definitively establish liability with the landlord.

For a conclusive inspection and a legally defensible report on responsibility, I recommend you contact our specialists at Saniservice. Call 800-MOLDS (800-66537) or email hello@saniservice.com to schedule a comprehensive assessment.
