Who is responsible for black mold in my bathroom?« Back to Previous Page

Responsibility for black mold in a Dubai apartment bathroom typically falls on the landlord for remediation, while the tenant is responsible for daily prevention. According to common tenancy law interpretations, the landlord must maintain the property’s structure and address issues inherent to it, such as faulty ventilation systems, leaking pipes, or waterproofing failures that cause persistent dampness. The tenant is expected to use the property reasonably, which includes ventilating bathrooms during and after showers to manage the high humidity levels prevalent in Dubai.

Your situation in Deira, with the mold recurring despite cleaning and spreading to the ceiling, strongly suggests an underlying moisture issue beyond simple surface condensation. This could be due to a hidden plumbing leak, inadequate waterproofing behind the tiles, or an exhaust fan that is underpowered or malfunctioning. These are structural or mechanical defects the landlord is obligated to rectify. Merely cleaning the grout is a temporary fix; the source of the moisture must be professionally identified and resolved.

Document the issue thoroughly with dated photos and a written communication to your landlord, stating that your reasonable ventilation efforts have not stopped the growth. Request a professional inspection to diagnose the root cause. A proper assessment often requires moisture meters and thermal imaging to find hidden water sources. If the landlord refuses, you may reference your rights under the rental contract and seek guidance from the Dubai Land Department's Rental Dispute Center (RDC). For health reasons, avoid attempting to remove extensive growth yourself, as improper disturbance can aerosolize spores. Professional remediation isolates the area and uses specialized equipment to remove the mold safely and address the moisture source.
