Is landlord responsible for mold in closet wall?« Back to Previous Page

That black mold in your Marina closet is a classic sign of condensation due to the high humidity we've had, exacerbated by your air conditioner creating a cold surface on that interior wall. The landlord is typically responsible for remedying this, as it's likely a structural or building envelope issue.

Under Dubai rental law (RERA), landlords must maintain the property in a habitable condition, which includes addressing structural defects that lead to moisture intrusion and mold growth. Since the mold is on the wall itself and not due to your actions (like storing wet clothes), the repair obligation generally falls on them. The first step is to notify them in writing with clear photos, as this documentation is crucial.

Do not use bleach. It only removes the surface discoloration and does not address the moisture source or kill the roots. More importantly, improper cleaning can aerosolize spores, spreading the problem.

A professional inspection is needed to identify the exact cause—it could be inadequate insulation within the wall (a common issue where cold AC meets humid air), a small plumbing leak from an adjacent bathroom, or even a breach in the building's external vapor barrier. The remediation process involves fixing the moisture source, properly removing the contaminated materials, and treating the area with specialized antimicrobial agents. For a case like this, involving a structural wall and a significant growth, a professional assessment is strongly recommended to ensure it is resolved correctly and to protect your health.
