From a technical standpoint, if your basement wall is leaking due to issues beyond normal wear and tear—like structural defects or inadequate waterproofing measures—it may fall under the landlord’s maintenance duties. However, if the problem arises from factors like poor external landscaping that directs water towards your unit’s foundation, it could be considered a tenant’s responsibility.

To navigate this effectively, I recommend engaging in a detailed inspection to determine the cause of the leak. Dubai Municipality, through its Building Control Department, has strict standards for building construction and maintenance. If you suspect non-compliance issues, contact them directly at 04-3952100 or visit their website for more specific guidance.

Furthermore, consulting a professional environmental inspection company can be highly beneficial. At SanIService, we specialize in assessing these types of issues. Our team can provide a comprehensive report delineating the source and extent of the water damage, helping you make informed decisions on who should address it.

In Dubai, property owners are advised to maintain their buildings according to the latest building codes. Should your landlord refuse to address the issue or if the problem is due to external factors, consider escalating the matter through your local municipality or even legal channels. Remember, proactive steps like addressing drainage issues and ensuring proper maintenance of exterior surfaces can prevent similar problems in the future.
