Who is responsible for bathroom mold, tenant or landlord?« Back to Previous Page

Based on the technical details you've provided, the black discoloration in your grout and ceiling is almost certainly active mold growth, a common issue exacerbated by Dubai's extreme humidity and condensation cycles. The persistent humidity in Deira, even with exhaust fan use, indicates a systemic moisture problem that typical cleaning cannot address.

Under UAE tenancy law (Law No. 26 of 2007), the responsibility for repairs is typically divided. The landlord is obligated to maintain the property's structure and ensure it is habitable, which includes providing and maintaining adequate ventilation systems. If the exhaust fan is underpowered or the building's external ventilation is insufficient for the climate, this is a structural issue falling under the landlord's purview. The tenant is responsible for day-to-day maintenance and ensuring the property is ventilated during use. Your weekly cleaning demonstrates due diligence.

However, the spread to the ceiling suggests a more serious infestation, potentially within the ceiling void or wall cavities, which requires professional assessment. Surface cleaning is a temporary fix; the underlying moisture source must be identified and controlled.

For a definitive determination of responsibility and a permanent solution, a professional inspection is critical. Our certified mold inspectors at Saniservice use thermal imaging and moisture meters to identify the precise source of moisture—whether it's condensation, a hidden leak, or inadequate ventilation. We provide a detailed report that can be used to clarify landlord responsibilities under UAE law.
