Is bathroom mold my responsibility or the landlord's?« Back to Previous Page

In the UAE, the responsibility for bathroom mold remediation is determined by the cause, as outlined in Dubai Rental Law No. 26 of 2007. The black, fuzzy growth you describe on grout is a classic sign of active mold colonization, not just surface staining. The high humidity and constant air conditioning use in Dubai create a perfect environment for mold, as AC units often lower the temperature without adequately removing ambient moisture, leading to condensation on cooler surfaces like tiles and grout.

If the mold is a result of tenant-specific behavior, such as failing to use the bathroom's ventilation fan during and after showers, the responsibility for cleaning may fall to you. However, your description of persistent dampness behind the toilet and the ineffectiveness of bleach treatment strongly suggests a more systemic issue. The recurrence indicates a persistent moisture source, which is likely inadequate ventilation—a fundamental building system that is the landlord's responsibility to provide and maintain in good working order. A malfunctioning extractor fan or a blocked ventilation duct would constitute a defect in the property.

For a definitive assessment, we strongly recommend a professional inspection. Our certified inspectors use moisture meters and thermal imaging cameras to identify the exact moisture source and air sampling to determine the spore count and species, which is crucial for health and remediation planning. DIY bleach cleaning often only bleaches the visible surface while the hyphae (root structure) remain embedded in the porous grout, allowing for rapid regrowth.
