Who is responsible for mold testing in a rental?« Back to Previous Page

Our AC unit in the master bedroom has been leaking a little for the past couple of months, and now I'm seeing these small black spots forming on the wall behind the curtain. My landlord says it's just dirt from the AC, but I'm worried it's mold, especially since my allergies have been worse. Who is responsible for getting this properly tested and fixed in a rental—me or the building management?

Based on UAE tenancy law, specifically Law No. (26) of 2007, the responsibility for maintaining the property's structural integrity and addressing issues that affect its habitability falls squarely on the landlord. This includes fixing the source of water intrusion, like your leaking AC unit, and remediating the resulting damage, such as the suspected mold growth.

The black spots you're seeing are a classic visual sign of a moisture problem. Given the AC leak and your worsening allergy symptoms—which are a common health effect of mold exposure—this is highly likely to be microbial growth, not simple dirt. Ignoring it can lead to further property damage and potential health issues.

Your first step is to formally notify your landlord or property management company in writing (email is best for a paper trail), detailing the leak, the visible signs, and your health concerns. Reference your right to a habitable property under the law. They are obligated to address the root cause.

For definitive proof, professional mold testing is crucial. A certified inspector can conduct air and surface sampling to identify the species and concentration, which is vital for proper remediation. Do not attempt to clean it yourself, as improper handling can aerosolize spores and worsen the problem.

If your landlord is unresponsive, you can escalate the matter to the Dubai Land Department (DLD) or the Rental Dispute Settlement Center. For immediate professional testing and a detailed report to present to your landlord, it's best to call in experts.
