Neighbour Noise Laws: Why Footsteps Count in Seoul and Not in New York

Four ways to handle the same problem

Line up the systems and they sort into four approaches. A national numerical standard. Quiet hours enforced through housing contracts. A split where measurement is required by day but not at night. And a decision not to legislate at all, leaving the question to the courts.

What counts as noise differs too. Korea puts running and walking at the centre of what it measures. New York removes those sounds from the definition of a violation. The same footsteps, treated as the core problem in one country and as ordinary life in another.

So the real question here is not how many decibels. It is where each society drew the line around the word noise.

How New York actually decides

The city noise code sits in the Administrative Code and was substantially revised in 2007. Complaints go to 311. Residential noise is handled by the police, while most other categories fall to the Department of Environmental Protection.

The operative test is amplification and audibility. If amplified sound from a residence can be heard inside a neighbouring unit with the windows shut, that can be a violation at any hour. Unamplified living sounds are not. No sound meter is used between apartments, and the responding officer judges by ear.

Residential quiet hours are given as 10pm to 7am on weekdays and 10pm to 9am on weekends. Animal noise has its own thresholds, ten continuous minutes during the day and five during quiet hours.

One caveat matters for American readers. There is no single federal rule here, so the city ordinance is the real standard, and this section describes New York rather than the United States.

The six systems side by side

Country	Form of regulation	Test applied	Night hours	Public channel
United States (NYC)	City ordinance	Amplified sound audible in the next unit	10pm to 7am, weekends to 9am	311, police and DEP
United Kingdom	Statutory nuisance plus night noise law	Duration, frequency, intensity, timing, area	Roughly 11pm to 7am	Council environmental health team
Germany	State law, house rules, tenancy law	Whether room volume is exceeded	10pm to 6am, all day Sunday	Landlord, police, rent reduction
France	Public health code and penal code	Abnormality by day, audibility at night	Roughly 10pm to 7am	Police attendance
Japan	No statutory regulation	Tolerance limit, judged as a whole	One factor among several	None. Building association, legal advice
South Korea	National rule setting decibel limits	39dB day, 34dB night, one-minute equivalent	Night limit applies	Mediation centre and dispute committees

Table: neighbour noise regulation compared across six countries. The kinds of authority differ. Korea's figures are a legal standard, while Japan's test comes from accumulated case law.

United States: the amplification line

Covered above. Worth adding one observation. Drawing the line at amplification is a decision about what can reasonably be asked of a neighbour, and it quietly concedes that buildings transmit sound. If the floor carries footsteps, that is treated as a fact of the structure rather than the conduct of the person upstairs.

United Kingdom: the council does the arguing

Under Part III of the Environmental Protection Act 1990, noise that is prejudicial to health or a nuisance is a statutory nuisance. Councils have a legal duty to investigate complaints, and where a nuisance is established they must serve an abatement notice. Failing to comply without reasonable excuse is a criminal offence, with fines and seizure of equipment available.

The assessment is contextual rather than a simple audibility test. Duration, frequency, intensity and character of the noise all count, along with the time of day and the character of the area.

The Noise Act 1996 adds a separate night-time power in England and Wales. Where residential noise between roughly 11pm and 7am exceeds a permitted level, a warning notice can be served, and continued excess after that notice becomes an offence. Scotland is outside this Act and Northern Ireland is governed separately.

Residents can also go directly to the magistrates' court rather than through the council. For noise and vibration the required advance written notice is three days.

The distinctive feature is who does the confronting. In the British system the dispute runs through a council team, not between two neighbours on a landing.

Germany: quiet hours and the lease

Night quiet runs from 10pm to 6am, and Sundays and public holidays are quiet all day. During those hours sound must stay at room volume. Even in daytime, music has to stay at room volume where it could disturb other residents unbearably.

Berlin's official guidance takes the unusual step of correcting two widespread beliefs. That you are entitled to one loud party a year, and that there is a legally fixed midday quiet period. Neither is true.

Remedies run through tenancy law. A tenant notifies the landlord of the defect, allows time, and can then reduce the rent. Where the problem is serious and repeated, the landlord can terminate the tenancy of the resident making the noise. The dispute becomes a contract matter rather than a personal one.

Children's noise has no fixed limit, and case law tends to widen what neighbours are expected to tolerate the younger the child is.

France: no measurement after dark

By day, article R.1336-5 of the public health code applies. No noise may impair the peace of neighbours or human health by its duration, its repetition or its intensity. That means abnormality has to be demonstrated.

At night the penal code provision on nocturnal disturbance takes over. No decibel reading is needed. If the sound is audible and plainly disturbing, that is enough.

One country, two tests, split by the clock. It is the simplest design of the six.

Japan: a decision not to regulate

Japan has no statute or local ordinance covering everyday household noise. Several municipalities state this on their own websites and explain that the city cannot step into a civil dispute between residents. The suggested route is a conversation between the parties, then the neighbourhood or building association, then free legal consultation at city hall.

Matsudo City goes further and gives its reasoning. Everyday noise is sound that anyone makes while living, so regulating it would mean placing limits on ordinary life.

Tokyo's guideline values are blunter still. They state that the values do not apply to noise and vibration between individual dwellings inside the same building.

Courts use the concept of a tolerance limit. Rather than a fixed decibel threshold, they weigh volume, frequency and time of day as the main factors, together with the construction of the building, the nature of the source, the age of any child involved and whether soundproofing was attempted.

The timing is worth noting. In the same period Korea was lowering its standard by four decibels, Japan held to having no standard.

South Korea: the country that put a number on it

Korean law defines the problem in two parts. Direct impact noise from running or walking, and airborne noise from televisions and audio equipment. Water supply and drainage noise from bathrooms and utility rooms is excluded.

A revision effective January 2023 tightened the direct impact limit from 43 to 39 decibels by day and from 38 to 34 by night, measured as a one-minute equivalent level. Older buildings approved before mid-2005 get an allowance added on top, five decibels through 2024 and two decibels from January 2025.

The government published its own estimate for the change. At the previous daytime limit, the share of residents finding the noise annoying was 30 percent, and at the new limit it expected 13 percent.

That last figure is the interesting part. The state tightened the standard and simultaneously recorded that annoyance would not disappear. Lowering a number and resolving a conflict are not the same task.

Korea also built channels for it. A dedicated centre handles consultation and measurement, lends sound meters through local governments, and separate committees exist for environmental disputes and for apartment management disputes.

What to do first

Whatever country you are in, the sequence starts the same way. Notify whoever manages the building. Keep a record of when the noise occurs, how long it lasts and what kind of sound it is.

That record is not busywork. Every system above weighs frequency and timing, and several weigh little else. Without dates and durations, none of the later steps open.

One thing has been changing about who is on the other side of the wall. Solo households reached 38.0 percent of the total in Japan and 36.1 percent in Korea, and the largest single group among Korean solo householders is people aged 70 and over: who actually lives alone in the US, Japan and Korea.

Frequently asked questions

Frequently asked

Are footsteps from upstairs a noise violation?

It depends entirely on where you live. New York excludes unamplified footsteps from its definition of a violation. Korea places them at the centre of a measured national standard. Germany sets no fixed limit for children's noise and expects more tolerance for younger children.

Can I call the police about a noisy neighbour?

In New York residential noise is a police matter and complaints go through 311. In Germany the police are one available route alongside the landlord. In the United Kingdom the council environmental health team is the primary channel, and in Japan the local authority states that it cannot intervene at all.

Does a decibel reading help my case?

Only where the system is built around measurement. Korea's standard is numerical and its public centre lends meters. New York does not use a meter between apartments, and French law requires no reading at night.

Is there a legally protected quiet time in the middle of the day?

Not in Germany, despite the widespread belief. Berlin's official guidance says so directly. Midday quiet, where it exists, usually comes from house rules rather than statute.
