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

In the UAE, the responsibility for mold remediation is determined by the root cause, as per the Dubai Rental Law (Law No. 26 of 2007). A recurring black mold issue, especially on an interior ceiling, is rarely the tenant's fault. While tenants are responsible for general upkeep and ventilation, structural or building envelope defects that lead to persistent moisture are unequivocally the landlord's responsibility.

Your description of a recurring patch, even with AC use, strongly indicates a hidden issue. The Dubai climate, with its extreme humidity and constant AC operation, creates significant condensation risks. The most likely culprits are a leak from the roof or a pipe within the ceiling slab, or severe thermal bridging and condensation due to inadequate insulation—a common issue in many villas. Bleach is a superficial fix; it only removes the visible stain but does not address the moisture source or the root fungal colony, which is why it consistently returns.

The landlord's claim that it's a ventilation issue is likely incorrect. A closet in an air-conditioned room should not develop recurrent mold from ambient humidity alone if the AC is functional. This persistent problem requires a professional inspection to identify the exact moisture source. A certified mold inspector, like our team at Saniservice, uses tools such as thermal imaging cameras and moisture meters to pinpoint the origin definitively. This report is crucial evidence to formally present to your landlord, outlining their legal obligation to conduct the necessary structural repairs. Only after the leak or insulation fault is fixed can the mold be properly remediated.
