Who is responsible for mold on rental apartment exterior wall?« Back to Previous Page

Mold on an exterior wall is typically the landlord's responsibility to remediate, as it often stems from a structural or maintenance issue like water seepage through the wall, faulty external waterproofing, or a leaking AC condensation pipe within the building's ducting. In Dubai's rental law, the property owner is generally obligated to maintain the structure and ensure the property is habitable.

Given your location in JVC and the timing after a humid period, the cause is likely condensation due to the thermal bridge between the hot exterior and your air-conditioned interior, or a hidden leak. Document the mold with dated photos and notify your landlord or property management company in writing immediately. They should arrange for a professional inspection to identify the moisture source—simply cleaning the visible mold without fixing the underlying cause will lead to its return.

If the landlord is unresponsive, you can reference Dubai's rental law and escalate the matter through the Rental Dispute Center (RDC). For health concerns, a professional assessment with moisture mapping and air quality testing can identify the spore types and concentration levels, which provides concrete evidence of the issue's severity. In the interim, improve air circulation in the closet and keep the bedroom door open to help reduce humidity buildup.
