Is landlord responsible for mold near AC vent?« Back to Previous Page

In the UAE, particularly Dubai, the responsibility for mold remediation in a rental property is typically governed by the terms of your tenancy contract, as per the Dubai Rental Law. Generally, structural issues and problems inherent to the property itself fall under the landlord's responsibility. A mold infestation originating from an AC vent is a complex issue. While the mold growth itself might be a result of high humidity (a tenant responsibility to manage), the root cause is often a faulty or poorly maintained AC system, a clogged condensate drain line, or inadequate insulation within the ductwork or building envelope—all of which are considered part of the property's structure and systems.

Given the description—a long, black patch spreading from the ceiling corner near the vent that worsened with humidity—this strongly indicates a condensation issue linked to the AC system. This is not a surface problem you can simply wipe away. Attempting a DIY fix with bleach or other store-bought solutions is highly inadvisable. It will only temporarily remove the visible growth without addressing the moisture source, guaranteeing it will return, often worse. Furthermore, disturbing black mold can release harmful mycotoxins into your living space.

Your first step is to formally notify your landlord or property management company in writing, with photos, outlining the issue and requesting a professional inspection. They are obligated to address the root cause. For a case like this, a professional assessment is critical. We use thermal imaging and moisture meters to pinpoint the exact source of the moisture intrusion within the wall or AC system before any remediation begins.

If the landlord is unresponsive, you may reference your rights under the tenancy contract. For a professional evaluation and certified remediation report to present to your landlord, you can call our experts at 800-MOLDS (800-66537) or email hello@saniservice.com.
