Who is responsible for mold by the bedroom AC vent?« Back to Previous Page

In the UAE, the responsibility for mold remediation is typically determined by the cause, as outlined in standard tenancy contract clauses and Dubai Law No. 26 of 2007 (as amended). The black mold growth emanating from your bedroom AC vent is a common issue in Dubai, primarily driven by our extreme humidity and condensation within AC systems.

The landlord is generally responsible for the maintenance and structural integrity of the property, including the central AC system and ductwork. If the mold is a result of a fault in the AC unit itself (e.g., a clogged drain pan, leaking refrigerant line, or poorly insulated ducts causing condensation), or a structural leak in the building envelope, the remediation cost falls to them.

However, tenant responsibilities include maintaining adequate ventilation and reporting issues promptly. If the mold is solely due to tenant behavior—such as consistently turning off the AC, leading to humidity buildup—the cost may be yours.

Given its location at the vent, this strongly suggests an AC or condensation issue. The fuzzy, black appearance indicates active growth, likely Stachybotrys chartarum or Aspergillus niger, which require professional assessment. DIY cleaning is not advised, as it can aerosolize harmful mycotoxins.

I strongly recommend a professional indoor environmental inspection to identify the precise moisture source. Our certified team at Saniservice uses thermal imaging, moisture meters, and air/o-surface sampling to provide a definitive report on causation, which is essential for determining liability with your landlord.
