Is recurring black mold my landlord's responsibility?« Back to Previous Page

Recurring black mold originating from inside the wall is almost certainly your landlord's responsibility to fix. The root cause is a building envelope issue, not surface condensation. In Dubai's climate, this often stems from a breach in the external waterproofing or a leaking internal AC condensation drain pipe running within the wall cavity.

Your description points to a persistent moisture source. Wiping it with vinegar only addresses surface spores; the hidden dampness inside the wall will continue to fuel regrowth. The constant AC use in Jumeirah Village Triangle is likely exacerbating the issue by creating a significant temperature differential that causes condensation on the cold inner wall surface if there's any moisture infiltration.

Under typical Dubai rental contracts (EJARI), the landlord is responsible for the structural integrity of the property, which includes fixing leaks and resultant damage like mold from within the walls. You should formally notify your landlord or property management company in writing, with photos, and request they investigate and remediate the source.

For a case like this, a professional inspection is advised to identify the exact moisture source. A moisture meter reading can verify the wall's dampness level, and a borescope inspection might be needed to see inside the cavity. The fix could involve repairing external cladding, resealing windows, or fixing the AC drain line. Until the leak is stopped, the mold will keep returning.
