Who is responsible for bathroom mold, tenant or landlord?« Back to Previous Page

In Dubai's climate, with its high ambient humidity and reliance on year-round air conditioning, the conditions for mold growth, particularly black mold (Stachybotrys chartarum), are unfortunately ideal. The issue you describe—black discoloration in grout and a persistent musty smell—is a classic symptom of a persistent moisture problem, not a cleaning deficiency. The weak ventilation fan is a critical factor, as it fails to expel the humid air generated from showers, leading to condensation and sustained moisture within the wall cavities and behind fixtures.

Legally, the responsibility for remediation in the UAE is typically determined by the source of the moisture. Under standard tenancy contracts, the landlord is responsible for maintaining the structural integrity and essential services of the property. This includes the proper functioning of ventilation systems, waterproofing, and addressing any inherent building defects that cause water intrusion. As the tenant, your responsibility is limited to general upkeep and promptly reporting such issues. Since you clean regularly and have identified an underperforming ventilation fan—a fixed installation—the liability for the root cause and the resulting mold remediation likely falls on the landlord.

However, a professional inspection is crucial to establish legal and factual clarity. The mold behind the toilet suggests a potential leak from plumbing or a failed seal, which is unequivocally a landlord responsibility. DIY cleaning is insufficient and can aggravate spore dispersal.

For a definitive assessment and legally compliant remediation report, I strongly recommend a certified inspection. Our team at Saniservice can conduct a comprehensive moisture mapping and air quality test to identify the exact moisture source and extent of contamination, providing a document that clearly outlines responsibility.
