Is landlord responsible for moldy bathroom grout in rental?« Back to Previous Page

The landlord is typically responsible for remedying the root cause of the mold, such as a faulty ventilation system or a water leak, as per Dubai rental law (Law No. 26 of 2007) which mandates landlords must maintain the property in a habitable condition. However, surface mold on grout due to daily use and humidity is often considered a tenant's responsibility for cleaning and maintenance.

Your situation points to a classic Dubai humidity issue. Exhaust fans in many apartments are undersized for the climate and simply recirculate air instead of venting it outside. This leads to persistent dampness, especially in less-circulated areas like behind a toilet. First, confirm the fan is actually exhausting air by holding a single sheet of toilet paper to it; if it doesn't hold the paper in place, the fan is ineffective.

You should formally notify your landlord in writing about the inadequate ventilation, as this is a habitability issue they are obligated to address. For the existing mold, a DIY cleaning with a dedicated grout cleaner or a diluted vinegar solution can be effective for surface-level issues. If the mold persists deep within the grout or reappears quickly after a proper cleaning, the underlying cause needs professional diagnosis to rule out hidden leaks or severe moisture retention in the walls.
