Is black mold in rental a tenant or landlord responsibility?« Back to Previous Page

In the UAE, the responsibility for black mold remediation in a rental property is primarily determined by the cause, as outlined in Dubai Law No. 26 of 2007 (Amended by Law No. 33 of 2008) and the standard tenancy contract.

The landlord is responsible for addressing mold if it results from a structural defect, such as a leaking pipe within the walls, faulty waterproofing, or a construction flaw that allows water ingress. This falls under their obligation to provide a property that is habitable and in good repair.

However, the tenant is typically held responsible if the mold growth is a direct result of their own actions or negligence. In Dubai's climate, this most commonly means failing to adequately manage indoor humidity generated by daily activities (showering, cooking, drying clothes indoors) and improper use of the AC system. Year-round air conditioning is not just for comfort; it is a critical dehumidification tool. Setting the AC too high and not running it consistently leads to massive condensation buildup, especially in enclosed spaces like closets, which is a primary catalyst for mold growth.

Given your description—an interior wall in a closet worsening with humidity—the cause is likely condensation due to poor ventilation and air circulation. While this may point to tenant-related air handling, a professional inspection is essential to definitively identify the moisture source.

I strongly recommend you cease DIY investigation and contact a certified professional like Saniservice.
