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

Recurring black mold behind a toilet is almost always a symptom of excess moisture, not just a surface cleaning issue. In a humid climate like Dubai's, this is a common problem exacerbated by bathroom condensation and inadequate ventilation.

Your responsibility as the tenant is typically to maintain cleanliness and report the issue. The landlord's responsibility is to provide and maintain a habitable property, which includes addressing the underlying cause of a persistent mold problem. This is often interpreted to mean fixing faulty ventilation fans, repairing leaking pipes, or improving sealing and insulation.

First, document the recurrence with dated photos and formally notify your landlord or property management company in writing. Reference that the issue is persistent and linked to humidity, suggesting an underlying building or ventilation issue.

For a proper fix, the source must be identified. A professional inspection can determine if the exhaust fan is underpowered or if there's a hidden leak from plumbing or a faulty seal. Simply scrubbing the surface will not stop it from returning. In many Marina apartments, the ventilation system is not adequate for the humidity levels, requiring a mechanical solution rather than just opening a window.

If the landlord is unresponsive, you can reference the Dubai Rental Law, which stipulates that the landlord must carry out maintenance for the property's essential facilities. A persistent mold issue affecting health and habitability could fall under this. A certified mold inspection report from a company with its own microbiology lab can provide the evidence needed to show this is more than a simple cleaning task, clarifying responsibility and the required remediation steps.
