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

My bedroom closet in our Marina apartment has started getting these black spots on the back wall, and my clothes have a faint damp smell. It's been getting worse since the humidity spiked a couple of weeks ago. I’m renting, and I’m not sure if this is something I need to handle myself with a dehumidifier or if I should be contacting my landlord to fix what might be a leak or an insulation issue. Who is typically responsible for treating mold in a rental—the tenant or the property owner?

Based on the UAE Civil Code and standard tenancy contract stipulations, the responsibility for treating mold in a rental property typically falls on the property owner or landlord. This is because mold is almost always a symptom of a underlying structural or maintenance issue, such as a hidden water leak from plumbing, faulty air conditioning drainage, or inadequate insulation within the walls—all of which are the landlord's legal responsibility to maintain and repair. The tenant is generally responsible for maintaining the property in a clean and hygienic condition and for reporting any such issues promptly.

In your case at the Marina apartment, the black spots and damp smell in the closet strongly suggest a persistent moisture problem. Given the high humidity, it could be exacerbated by poor ventilation or a concealed leak. Your first step should be to formally notify your landlord or property management company in writing immediately. Do not attempt to clean it yourself with bleach, as this will only temporarily remove the visible stain without addressing the root moisture cause, and the mold will return. A professional inspection is crucial to identify the source. We often find issues like leaking AC drain lines or seepage from adjacent bathrooms in such buildings.

For a definitive assessment and to ensure your landlord addresses the correct problem, I recommend a certified mold inspection. Our team can identify the moisture source, test the mold type, and provide a remediation protocol for the landlord to follow. Call us at 800-MOLDS (800-66537) or email hello@saniservice.com to schedule an assessment. This will protect your health and your personal belongings and provide the documentation needed to ensure your landlord fulfills their obligation.
