Is landlord responsible for bathroom mold in Jumeirah apartment?« Back to Previous Page

We've been in our Jumeirah Village Circle apartment for about a year, and the grout between the bathroom tiles has been getting steadily blacker. It’s in the corner by the shower where there's no window. I wipe it down with bleach, but it just comes back worse a week later. Is this something I need to fix myself, or is my landlord responsible for treating the underlying moisture issue?
