Landlord responsible for mold from building leak?« Back to Previous Page

The wall behind our wardrobe in the bedroom has a large black splotch of mold that’s been slowly growing since the humidity spiked a few weeks ago. We’re in an older building in Deira and I’m worried it’s a leak in the building’s wall, not something we caused. Our lease says we're responsible for maintenance, but this seems structural. Who is legally responsible for the mold removal and repair costs, us or the landlord?

Based on the details you've provided, this is a common yet serious issue we encounter in older Deira buildings. The presence of a large, growing black splotch behind a wardrobe strongly suggests a hidden moisture source, likely a leak in the building's structural envelope or a faulty pipe within the wall cavity. The wardrobe creates a cold spot with poor air circulation, which, combined with our high Dubai humidity and year-round AC use, creates a perfect incubator for mold.

Legally in the UAE, the responsibility for repairs and resultant mold remediation is determined by the source of the moisture. According to typical rental law interpretations (Law No. 26 of 2007), the landlord is unequivocally responsible for maintaining the property's structural integrity. This includes the external building envelope, main water lines, and central AC drainage systems. If the leak originates from a structural defect or a neighboring unit, the financial responsibility for the investigation, mold removal, and repairs falls on the property owner.

However, your lease's maintenance clause typically applies to internal fixtures and appliances, not structural defects. You must notify your landlord in writing immediately. Do not attempt to remove the mold yourself, as improper disturbance can aerosolize toxic spores throughout your bedroom.

A professional inspection is critical to definitively identify the moisture source and the mold species. We use thermal imaging cameras and moisture meters to pinpoint leaks without destructive investigation. This technical report is essential evidence for your landlord to accept responsibility.

For a definitive assessment and a legally valid report, I strongly recommend you contact our specialists. Call Saniservice at 800-MOLDS (800-66537) or email hello@saniservice.com to schedule an inspection. Delaying can allow the structural damage and health risk to escalate significantly.
