Noise & Ruhestörung in a Rental: Landlord Guide 2026

What counts as a Ruhestörung (noise disturbance) under German tenancy law?

A Ruhestörung exists when noise from a flat impairs life in the building more than insignificantly – particularly during the statutory Ruhezeiten (quiet hours). The guiding principle is mutual consideration: neighbours must tolerate normal household noise, but not avoidable or excessive noise.

The sentence that matters most for landlords: a repeated, sustained Ruhestörung justifies an außerordentliche (extraordinary) termination without notice under § 569 Abs. 2 BGB – but normally only after a prior Abmahnung (formal warning, § 543 Abs. 3 BGB). Without a documented Abmahnung, the Kündigung (termination) almost always fails.

Which Ruhezeiten apply? (Nachtruhe and Mittagsruhe)

Nachtruhe (night quiet) applies nationwide, typically from 22:00 to 06:00. During this window Zimmerlautstärke (room volume – audible only inside the flat itself) applies; noise must essentially not be perceptible outside the tenant's own flat. Nachtruhe is anchored in the state immission-protection laws and municipal noise ordinances.

There is, by contrast, no nationwide statutory Mittagsruhe (midday quiet). It derives at most from state law, a municipal ordinance or the Hausordnung (house rules), commonly 13:00 to 15:00.

Achtung: A termination for Ruhestörung without a prior, documented Abmahnung is almost always invalid under § 543 Abs. 3 BGB. Warn in writing first, describe the specific incidents with date and time, and state a clear expectation – otherwise you will lose in court.

What can the Hausordnung regulate?

The Hausordnung may specify and even tighten the statutory Ruhezeiten – for example, extend Nachtruhe to 07:00 or add a Mittagsruhe – as long as the rule does not unreasonably disadvantage the tenant. But the Hausordnung only binds the tenant if it is incorporated into the Mietvertrag (tenancy agreement) or agreed as an annex to it. A mere notice posted in the stairwell is generally not enough to create binding obligations.

Note: even a strict Hausordnung cannot demand Zimmerlautstärke around the clock and cannot prohibit Kinderlärm (see below).

Noise as a defect: when does another tenant reduce rent? (§ 536 BGB)

If a tenant disturbs the peace persistently, it is not only that tenant's problem – it affects the other tenants in the building too. Persistent, more-than-insignificant noise is a Mangel der Mietsache (defect of the rental property) that entitles the affected tenant to a Mietminderung (rent reduction) under § 536 Abs. 1 BGB. There is no binding Minderungstabelle (reduction table); the rates depend on the individual case. In individual court decisions they have ranged roughly between 5 and 25 percent depending on severity – these are reference points, not fixed values.

The affected tenant does not need to keep a minute-by-minute Lärmprotokoll (noise log). The BGH ruled on 29.02.2012 (Az. VIII ZR 155/11) that a description of the disturbances by type, approximate time, duration and frequency is sufficient.

For you as landlord this means: if a tenant lawfully reduces rent because of noise from another tenant, you have a duty to act against the source – via Abmahnung and, if necessary, Kündigung. Otherwise you bear the shortfall.

Step by step: how to act against a noisy tenant

1. Document the incidents – record date, time, type and duration of the disturbance, plus witnesses. Collect complaints from other tenants in writing.
2. Issue an Abmahnung – in writing, with a concrete account of the incidents, a clear demand to stop and a reference to a possible Kündigung. The Abmahnung is a prerequisite for the later termination under § 543 Abs. 3 BGB. Send it so delivery can be proven (e.g. registered post).
3. Wait for a deadline and the response – if the disturbance continues despite the Abmahnung, the risk of repetition is established.
4. Assess the Kündigung – for a sustained disturbance, an ordentliche (ordinary) termination for breach of duty (§ 573 Abs. 2 Nr. 1 BGB) or an außerordentliche termination without notice (§ 569 Abs. 2 BGB), with reasons and a reference to the Abmahnung.

Kinderlärm: privileged and usually not a defect (§ 22 Abs. 1a BImSchG)

The sounds of children playing, shouting or running about are expressly privileged under § 22 Abs. 1a BImSchG. They are deemed socially adequate and, in case of doubt, must be tolerated. A Mietminderung for privileged Kinderlärm generally does not exist, because there is no Mangel within § 536 BGB.

The limit: excessive, avoidable noise that goes beyond normal living – for example adults' parties at night or loud technical installations – is not privileged and may well constitute a defect.

Ordentliche vs. außerordentliche Kündigung for Ruhestörung

Feature	Ordentliche Kündigung (ordinary)	Außerordentliche fristlose Kündigung (without notice)
Legal basis	§ 573 Abs. 2 Nr. 1 BGB	§ 569 Abs. 2 BGB with § 543 BGB
Requirement	serious culpable breach of duty	sustained disturbance of the Hausfrieden
Abmahnung needed	as a rule yes	yes (§ 543 Abs. 3 BGB)
Notice	statutory notice period	immediate
Severity	repeated breaches	especially severe or especially frequent

In practice, an ordentliche Kündigung is often declared in the alternative at the same time, in case the außerordentliche termination fails on the threshold of "sustained" disturbance.

Common mistakes by landlords

• Terminating without an Abmahnung – the Kündigung almost always fails under § 543 Abs. 3 BGB.
• Not documenting incidents – without date, time and witnesses, the sustained nature of the disturbance cannot be proven.
• Issuing an Abmahnung for Kinderlärm – privileged under § 22 Abs. 1a BImSchG; a warning or termination on that basis is regularly invalid.
• Ignoring other tenants' complaints – failing to act against the source risks justified Mietminderung claims from the other tenants under § 536 BGB.
• Relying on a single incident – one-off or isolated incidents do not amount to a sustained disturbance of the Hausfrieden.

HausMaus makes this easier

HausMaus brings every step together, from the first complaint to the Kündigung. In the document vault / digital Mietakte (rental file) you store complaints, Abmahnungen and their proof of delivery in an audit-proof way per tenancy – the complete documentation that § 543 Abs. 3 BGB requires. If the Ruhestörung continues despite the Abmahnung, you generate the matching Kündigung letter directly in the app, referencing the documented incidents and sent as registered post. That keeps the process on solid legal ground and provable.
