Is landlord responsible for mold in rental bedroom?« Back to Previous Page

Based on the conditions you've described, this is a complex issue that typically involves shared responsibility between tenant and landlord, but the initial legal onus for investigation and remediation of structural issues often falls on the property owner in the UAE.

The black mold in an exterior wall corner, exacerbated by the heavy dew season, is a classic symptom of a condensation issue. In Dubai's climate, this is frequently caused by a thermal bridge—where the wall's insulation is compromised, allowing the cold interior air from your AC to meet the warm, humid exterior air, leading to condensation and subsequent mold growth. This is a building envelope defect, not a result of tenant lifestyle (like excessive indoor drying of clothes).

Under standard Dubai rental law (Law No. 26 of 2007), landlords are responsible for maintaining the property's structural integrity and ensuring it is habitable. A mold infestation stemming from an inherent construction or insulation flaw is typically considered the landlord's responsibility to rectify. As a tenant, your responsibility is to report the issue promptly and maintain good ventilation practices to mitigate indoor humidity.

However, a professional inspection is critical to determine the exact cause and source of moisture. We strongly recommend you formally notify your landlord in writing about the issue and request a comprehensive mold inspection. Do not attempt to clean it yourself, as improper disturbance can aerosolize toxic spores.

Our company, Saniservice, specializes in such diagnostics. Our certified inspectors use thermal imaging cameras to identify hidden moisture and cold spots precisely, alongside air and surface sampling to speciate the mold and assess the health risk. This technical report is vital for definitively establishing liability between tenant and landlord.
