Living next to a noisy neighbour can be more than a nuisance -- it can impact your quality of life. Listening to your neighbour's loud music at all hours of the day and night can impact your ability to sleep, enjoy time with family and simply live in peace. Sending a warning letter to your neighbour to politely ask him to turn down the music is the first step in finding some peace in your own home. Choose this route before going to your homeowners' association or the police.
Document the noise violations committed by your neighbour. You want to have evidence before you write your letter. So, if your neighbour's loud music is persistent, make a note of the date and time of the noise violation for at least a week. This will serve as your evidence when you write your complaint letter.
Check your neighbourhood guidelines, such as a homeowners' association, or HOA, manual, for any rules that pertain to excessive noise. Familiarise yourself with these rules so that you can reference them in your complaint letter.
Address your letter to your neighbour. If you're on a first-name basis with the noisy offender, address it informally using his first name -- for example, "Dear Tom." If you don't know him well, use a more formal title, such as "Dear Mr. Johnson." You might not know your neighbour's name at all, in which case "Dear Sir" is appropriate.
Explain the purpose of your letter in the first paragraph. Tell the noisy neighbour that you are writing to discuss the loud music that he's playing. Cite specific examples of the loud music offences; refer to the log that you took. For example, you can write, "Last week, your loud music disturbed my family nightly from 10 p.m. to 1 a.m." Be as specific as you can about the offences.
Include a call to action in the letter. Ask your neighbour outright to stop playing loud music. Cite any HOA rules; for example, if the HOA limits excessive noise after 9 p.m., remind him of this rule. State that you expect the excessive noise to stop immediately.
Inform the noisy neighbour of your next steps. Tell him that if he fails to comply with your request to turn down the music, you will report him to the HOA, if applicable, or the police. While you don't want to end your letter on a threat, you do want to encourage your neighbour to turn down the music to eliminate further conflict.
If you have met your noisy neighbour and are comfortable knocking on his door to chat, then talk to him about the loud music before sending a formal complaint letter. He might not even realise that you can hear his music and he might comply with your face-to-face request. If he doesn't, send a letter to formally complain.
