Is landlord or tenant responsible for black mold cleanup?« Back to Previous Page

Responsibility typically falls on the landlord for structural issues causing the mold. Since the mold is on an outside wall and worsened by recent humidity, the root cause is likely penetrating dampness from a leak or inadequate insulation—both structural defects. In Dubai, landlords are generally responsible for maintaining the property's structure and exterior under standard tenancy contracts.

Your first step is to notify your landlord or property management company in writing immediately, including clear photos. They are obligated to address the source of the moisture intrusion. However, if the mold growth was directly caused by tenant negligence, like a spill not reported or a lack of ventilation, you could be held responsible for the cleanup. Given its location in a closet on an outside wall, this is almost certainly a building issue.

For a case like this, a professional inspection is wise to confirm the moisture source and the mold type. While often called "black mold," many species are dark-colored; only lab analysis can identify if it's Stachybotrys, which requires more careful handling. Remediation involves fixing the water leak first, then properly removing the contaminated materials. Do not attempt to clean it with bleach yourself, as this can worsen airborne spores.

The high humidity in Dubai, especially combined with cold spots on exterior walls from constant AC, creates perfect conditions for condensation and mold. Once the landlord fixes the leak, using a dehumidifier in that room can help prevent recurrence.
