In rental housing with children, noise from footsteps and daily living can easily cause neighbor conflicts. This guide explains soundproofing measures, good etiquette, and how to handle complaints—from an expert perspective.
A step-by-step guide to handling noise and neighbor disputes that commonly occur in rental housing. Learn whether to address the problem directly or consult your management company, how to keep records, how to use legal remedies, how to use a sound meter, and more. A rental real estate professional provides practical advice.
When a problem occurs in your rental, who do you call? This guide covers management company, emergency repair services, and utility companies by situation, plus how to reach your management company on Sundays, year-end/new year holidays, and after-hours; what "emergency contact" means in your lease; and what to do if you have no one to list.
Upper-floor noise can be broadly divided into two types: "light-impact floor noise" and "heavy-impact floor noise."
Light-Impact Floor Noise: Sounds like dragging chairs, dropping small objects, and footsteps in slippers. These sounds travel easily even in reinforced concrete (RC) structures and are difficult to completely prevent without structural improvements to the building.
Heavy-Impact Floor Noise: Sounds like children running, jumping, and loud stomping footsteps. While rugs and soundproof mats, or wearing slippers can reduce these, fundamental behavior change is ultimately necessary.
Documentation is the most important element in resolving noise issues. Rather than emotional complaints, specific records of dates, times, content, and frequency become valid evidence in dealing with management and in legal proceedings.
What to Document:
Reporting to Your Building Management Company: Report to your building management company by email (a format that creates a record) based on your documentation. Verbal reports alone can easily become "he said/she said," so always communicate in writing.
Example wording: "Between 10:30 PM and 11:15 PM on [date], I heard loud running sounds from the unit above. This type of noise occurs approximately 3–4 times per week, and it is disrupting my sleep. I would appreciate your immediate attention to this matter."
The building management company can issue written warnings or make in-person visits to the upstairs resident.
If the management company is slow to respond: Follow up with "It has been one week since I reported this on [date], and no improvement has been observed. I will continue documenting the situation and request your continued, concrete action."
The management company has a legal duty to address noise issues (this is the landlord's obligation). If the company ignores your complaint, you as a tenant may have grounds to request rent reduction or contract termination based on "interference with your right of use and enjoyment."
If there is no improvement after the management company issues a warning, direct negotiation may be an option depending on the situation. However, we strongly recommend starting with a polite letter and avoiding emotional reactions.
Actions to Avoid in Direct Negotiation:
These actions can escalate the situation and may even result in complaints being filed against you.
When the upstairs resident has children, they often create noise unintentionally, and there is often room for improvement if they are notified.
When reporting to the management company, using considerate language such as "While I don't believe this is intentional, the running of your child—particularly in the evening—is creating noise. Would you be willing to discuss installing soundproof mats or limiting activities in the evening?" can prevent the relationship with the upstairs resident from deteriorating.
In addition to addressing the upstairs noise, you can improve your living comfort by implementing soundproofing measures in your own unit.
If the noise continues for six months or longer and both the management company and upstairs resident fail to improve the situation, consider the following options:
Consult a Lawyer: You may be able to claim damages for emotional distress and sleep disruption caused by the noise. Medical documentation (sleep disorder diagnosis, etc.) and your noise records will be needed as evidence.
Contact Your Municipality's Noise Complaint Office: You can request noise measurement and administrative guidance.
Consider Moving: If the noise issue stems from building structure (even RC structures can transmit noise severely) or if the management company's response is inadequate, moving may be the most reliable solution.
