Most neighbour disputes are resolved without going to court
Before imagining the worst, know that 80% of noise-related neighbour conflicts are resolved amicably or through the landlord or building manager, without going to court. The key: act in stages and keep a written record of every step. A precise incident log (dates, times, nature of the noise, duration) is your best tool.
What legally constitutes a noise nuisance
Actionable noise falls into two categories. Behavioural noise: late parties, loud music after 10pm, barking dogs, heels on hard flooring, repeated shouting. Tapage nocturne (noise after 10pm or before 7am) is a criminal offence subject to a fine. Activity noise: building work outside permitted hours (generally 8am–8pm on weekdays, 9am–7pm on weekends depending on the municipality).
The step-by-step procedure: don't skip steps
Step 1: try direct dialogue with the neighbour — often effective with new neighbours who don't realise they're causing a disturbance. Step 2: if no improvement, notify your landlord or building management company in writing. Step 3: contact the municipal mediator or the town hall. Step 4: police report and/or legal action.
How to write your letter to the landlord or building manager
Be precise and factual: list incidents with dates, times and nature of the noise. Attach your incident log if you have one. Mention the steps you've already taken (attempted dialogue). Explicitly request intervention with the tenant concerned and a written response on the measures taken.
Your rights if the situation doesn't improve
If the noise makes the property uninhabitable and your landlord doesn't act despite your written requests, you can go to court for a rent reduction proportional to the disturbance suffered, damages, and in extreme cases, termination of your tenancy without notice.
