who handles mold by ac vent: tenant or building?« Back to Previous Page

In Dubai, responsibility typically depends on the source of the moisture. For mold originating from an AC unit or its condensate drain line—a very common issue here due to high humidity and year-round AC use—the building management is usually responsible for the repair and remediation of the building structure itself, like the ceiling. This is because the AC system is often considered a central building fixture.

As the tenant, you are generally responsible for reporting the issue promptly and for the contents within your apartment. Document the growth with photos and send a written notification to your property manager immediately. Delaying can lead to the argument that you failed to mitigate the problem, potentially making you liable for further damage.

However, the cause must be verified. The black substance must be professionally identified, as dirt and dust can sometimes mimic mold. More critically, a diagnostic inspection is needed to confirm if the issue is a clogged drain pan, an undersized AC unit causing excess condensation, or a leak from another apartment. For a confirmed mold case tied to the AC, the building should rectify the faulty system and repair the ceiling. You may be asked to cover the cost of cleaning your belongings and any interior painting after the leak is fixed. Always request that the management uses a company that provides before-and-after lab testing to verify the space is safe.
