Is black shower grout my responsibility as a tenant?« Back to Previous Page

Black shower grout is likely your responsibility as tenant maintenance, but the underlying cause may be the landlord's duty to repair. Tenancy law in Dubai typically holds tenants responsible for minor upkeep and cleaning, which includes surface mold removal from grout. However, if the root cause is a building-level ventilation issue or a hidden water leak, that is generally the property owner's responsibility to address.

The persistent return of the mold indicates a chronic humidity problem, which is extremely common here due to our climate. Showers generate significant moisture, and if the bathroom's exhaust fan is underpowered, broken, or vents improperly, that humidity has nowhere to go. It condenses on cool tile surfaces, feeding mold growth deep within the porous grout. Scrubbing only removes surface discoloration, not the root fungus.

First, check if your bathroom's exhaust fan is operational and actually moving air. You can hold a single square of toilet paper up to it; if it doesn't hold the paper in place, the fan's suction is inadequate. Inform your landlord in writing about the persistent mold and the potential ventilation issue, as this is a habitability concern. Request that they check the fan's functionality and the ventilation ducting.

For a definitive answer on responsibility, a professional inspection can identify if the problem is purely superficial (tenant) or a systemic building issue (landlord). They can perform a moisture reading on the walls and assess the ventilation rate. If the landlord is unresponsive, you can file a case with the Dubai Rental Dispute Center (RDC), as a faulty ventilation system that impacts health and habitability is often grounds for the owner to make repairs.
