Noise and neighbor disturbances in Peru: what the law says

What does Article 961 of the Civil Code protect?

Peru’s Civil Code (Decreto Legislativo N.° 295, 1984) regulates, within Book V on Property Rights, the limits on property ownership when its exercise affects neighbors. Its Article 961 states, in its exact words, that the owner “must refrain from harming adjoining or neighboring properties, the safety, peace, and health of their occupants” (“debe abstenerse de perjudicar las propiedades contiguas o vecinales, la seguridad, el sosiego, la salud de sus habitantes”), and that “smoke, soot, fumes, noise, vibration, and similar disturbances that exceed the tolerance neighbors mutually owe each other given the circumstances” are prohibited.

Two ideas matter for how this rule works in practice:

• Not all noise is prohibited. The law recognizes that living near other people involves some mutual tolerance: a bit of everyday noise — children playing, an occasional gathering, a daytime drill — is normal and expected. What the law prohibits is noise that exceeds that reasonable tolerance “given the circumstances” (the time of day, the frequency, the zone, the duration).
• The article alone does not set an exact number. Article 961 establishes the general principle — do not harm a neighbor beyond what is tolerable — but it is a separate technical regulation, Supreme Decree N.° 085-2003-PCM, that translates that principle into concrete decibel limits by zone. The two norms work together: one gives the right, the other gives the measure.

The technical limits: the noise table under Supreme Decree N.° 085-2003-PCM

The National Environmental Quality Standards Regulation for Noise, approved by Supreme Decree N.° 085-2003-PCM, sets maximum permitted noise levels by zone type and time of day. These are the official limits:

These limits apply based on the zoning of the property where the noise originates, not the zoning of whoever hears it. So if your home sits next to a commercial zone, it is reasonable to expect — and legally tolerate — somewhat higher noise levels than if you lived in a purely residential zone. Your district municipality can tell you the exact zoning that applies to your property and your neighbor’s.

Who enforces this: the municipality, not a judge (in most cases)

The Organic Law of Municipalities (Ley N.° 27972), in Article 80(3.4), gives municipalities the specific function of “inspecting and controlling the emission of smoke, gases, noise, and other pollutants into the atmosphere and the environment”. This means that, for the vast majority of neighbor-noise disputes, the complaint process does not start in a courtroom — it starts at your district municipality.

In addition, when noise poses a health risk, the General Health Law (Ley N.° 26842), in Article 105, gives the competent Health Authority the power to “issue measures to minimize and control health risks to people arising from environmental elements, factors, and agents” — which, in principle, includes noise as an environmental factor with a health impact.

In practice, this creates two parallel administrative routes (not mutually exclusive):

1. The municipal route: the most common one. It is handled by the Enforcement and Control Management office (the exact name varies by district), which can schedule a technical sound-level measurement and, if the limits under Supreme Decree N.° 085-2003-PCM are exceeded, open a sanctions procedure.
2. The health route: more relevant when the noise directly affects your health (prolonged insomnia, stress documented by a health professional, and so on), through the competent Health Authority.

Practical steps against a noisy neighbor

1. Document the noise: dates, times, duration, and, if possible, a short recording with a visible timestamp.
2. Talk to the neighbor first — many cases resolve without any formal process at all.
3. Check the decibel limit for your zone in the Supreme Decree N.° 085-2003-PCM table, or ask your municipality directly.
4. File a complaint with your district municipality, citing Article 80(3.4) of the Organic Law of Municipalities.
5. If the noise comes from a construction site, check the permitted work hours in your district (set by each municipality’s own ordinance).
6. In serious, persistent cases, or where real harm to your health is involved, consult a lawyer about a civil claim, or — only in especially serious and systematic scenarios — evaluate whether the case could fit Article 304 of the Criminal Code.

When does it become a crime? Article 304 of the Criminal Code

Article 304 of the Criminal Code, as amended by Legislative Decree N.° 1351, punishes anyone who, “in violation of laws, regulations, or maximum permissible limits,” causes emissions — expressly including “noise emissions” — that “cause or could cause serious harm, alteration, or damage to the environment or its components, environmental quality, or environmental health,” with a prison sentence of between four and six years (or up to three years if the person acted negligently, without intent).

It is important to read this carefully: the provision requires both a legal-limit violation and serious harm — or at least a real possibility of serious harm — to the environment or to environmental health. It is a standard aimed mainly at industrial or systematic noise pollution (a factory operating continuously above the legal limit, for example), not at one-off incidents like a party that runs later than it should. The overwhelming majority of neighbor-noise disputes are resolved — and should first be pursued — through the municipal administrative route, not the criminal one.

The civil route: seeking a cease-and-desist and damages

Beyond administrative enforcement, the extracontractual civil liability rules of Peru’s Civil Code give an additional basis for a court claim seeking both a cease-and-desist and damages for the harm suffered.

Article 1969 sets out the general rule: “Aquel que por dolo o culpa causa un daño a otro está obligado a indemnizarlo. El descargo por falta de dolo o culpa corresponde a su autor.” (“Anyone who through intent or negligence causes harm to another is obligated to compensate for it. The burden of proving the absence of intent or negligence falls on the person who caused the harm.”) This means that if you sue your neighbor over the harm from their noise, you do not have to prove they acted negligently — your neighbor has to prove they did not, a burden of proof that favors the person suffering the disturbance.

Article 1970, on strict liability for risky or dangerous property or activities, normally does not apply to ordinary neighborhood noise (a party, home construction, a pet): that regime is meant for intrinsically dangerous activities, not everyday noise between neighbors.

If a neighbor’s noise has caused you real, persistent, and documentable harm — for example, health harm certified by a professional, or concrete financial losses — the recommended step is to consult a lawyer about the specific viability of this kind of claim, rather than assuming a particular procedure here.

This is not the same as…

Article 961 of the Civil Code is often confused with related but different rules:

• Digging wells that damage a neighboring property (Article 962 of the Civil Code): immediately after Article 961, Article 962 regulates a completely different problem: the prohibition on opening or digging wells that could damage a neighbor’s property (for example, by affecting the stability of the land or a structure). It has nothing to do with noise or other disturbances like smoke or vibration; it is a rule about structural damage to a neighboring property, not about noisy coexistence.
• Boundary disputes (deslinde): a neighbor’s noise has nothing to do with exactly where the dividing line between two properties runs. If your problem is that you are not sure where your land ends and your neighbor’s begins, that is a different situation, covered in our guide on boundary disputes and deslinde between neighbors.
• A building’s or condominium’s internal rules: if you live in a building, quinta, or condominium under a shared ownership regime, its Junta de Propietarios (owners’ association) may have its own rules on quiet hours or common-area use, in addition to — not instead of — the legal limits covered on this page. See our guide on owners’ associations and common expenses for more on that regime.
