AC leak causing mold: landlord or tenant responsibility?« Back to Previous Page

This is a common and serious issue in Dubai, particularly in areas like Jumeirah due to the high humidity and constant AC operation required for most of the year. The condensation from an AC unit, if not properly drained, creates a perpetual moisture source, which is the primary catalyst for mold growth. The fact that the mold returns aggressively after wiping confirms the moisture source is active and the contamination is likely within the wall cavity.

Under UAE tenancy law, specifically Dubai Law No. 26 of 2007 (as amended), the responsibility for major maintenance and structural repairs falls upon the landlord. This includes the repair of the air conditioning system itself and any resultant damage to the property's structure, such as water intrusion and mold proliferation inside the walls. Your responsibility as a tenant is typically limited to minor maintenance and reporting the issue in a timely manner.

You must formally notify your landlord or property management company in writing about the AC leak and the subsequent mold growth immediately. Do not attempt further DIY cleaning, as this can aerosolize spores and exacerbate the problem. The remediation process is technical: it requires isolating the area, using HEPA filtration, removing affected porous materials (drywall, insulation), treating the cavity with antimicrobial agents, and finally repairing the structure. Crucially, the root cause—the AC leak—must be fixed by a certified HVAC technician to prevent recurrence.
