Who is responsible for rental mold from humidity?« Back to Previous Page

This is an excellent and very common question here in Dubai. The extreme coastal humidity in Marina, combined with the specific construction of high-rises, creates a perfect storm for these issues.

Determining liability for mold from humidity in a rental property hinges on the source of the moisture. Under UAE rental law (Law No. 26 of 2007), the landlord is responsible for the structural integrity of the property and for maintaining the main building systems. This includes the central air conditioning system, which is the primary defense against humidity. If the mold is a result of a faulty AC unit that is not properly dehumidifying the air, a leaking pipe within the walls, or a structural defect allowing moisture ingress, the landlord is unequivocally responsible for the remediation and repairs.

However, tenant responsibilities are also clearly outlined. The tenant must maintain the property through adequate ventilation and reasonable use. If the humidity issue is exacerbated by a lack of AC use, blocking vents (like in a closed closet), or activities that generate excess moisture without proper exhaust, the liability for the resulting damage, including personal belongings, may fall on the tenant.

In your case, a damp closet wall in a high-rise strongly suggests an underlying issue. It could be a leaking AC condensate drain line servicing the apartment above you, poor insulation on a cold water pipe causing condensation (sweating), or a failure of the building's external vapor barrier. This is not typical condensation and points to a systemic problem.

Your first step is to formally notify your building management AND your landlord in writing, detailing the issue. They need to investigate the source. Given the potential for hidden damage and health concerns from mold, I strongly recommend a professional inspection to identify the precise cause and extent. This provides an unbiased report to determine liability.
