Noise

You, and everyone else who lives in your building, are entitled to what is called peaceable enjoyment of the premises. Excessive noise can disrupt peaceable enjoyment of the premises. 

If you are seriously inconveniencing your neighbours by being noisy, and your landlord has given you warnings but you have not significantly reduced your noise levels, your landlord can ask the Tribunal Administratif du Logement to cancel your lease. The Tribunal may then either cancel the lease immediately or give you a set date by which to end the noise, otherwise they will cancel your lease. 

If you are being inconvenienced by noise

• First, tell your landlord about it. It is their responsibility to resolve the problem 
• If your landlord does not resolve the problem, send them a formal notice by registered mail in which you give him a formal new deadline (e.g. a 10-day period) in which to act, failing which you will intervene through the Tribunal. Keep a copy of this formal notice and proof of receipt of the original formal notice.
  • You can use this noise letter template to send your formal notice 
• If the noise has not been addressed after the formal new deadline passes, you may:
  •  Ask for immediate cancellation of your lease (in serious cases requiring intervention);
  • Ask for a reduction in rent if the noise prevents you from fully enjoying your dwelling; or
  • Claim damages from your landlord unless he can prove to you that he has tried everything in his power to get his tenants to stop the  noise.
