When may I renovate my flat and make noise?
There is no national "quiet after 10 pm" for renovations. Construction noise in Liechtenstein is regulated twice: through the Noise Abatement Ordinance (LSV) for fixed installations and building sites, and through the building hours of the municipalities. In Schaan, for instance, noisy construction and commercial work is forbidden from 12 to 1 pm and from 7 pm to 6.45 am (regulation Art. 21/22). The myth: "For construction noise the Swiss dB values and a 10 pm night quiet apply." Wrong — the Construction Noise Guideline is a Swiss enforcement aid, not Liechtenstein law; what governs are the LSV and the municipal regulation. And anyone who renovates as a tenant, or has work done, must also keep in mind neighbour law (Art. 67 SR) and a possible rent reduction.
📋 The rules
- No national quiet-hours law for private parties: construction noise is captured through the Noise Abatement Ordinance (LSV) on the basis of the Environmental Protection Act — it governs fixed installations, building sites, traffic and industry. A general federal or national law "night quiet from 10 pm" for private renovations does not exist.
- The municipality sets the building hours: in Schaan noisy construction and commercial work is forbidden from 12 to 1 pm and from 7 pm to 6.45 am (regulation Art. 21/22) — tighter windows than for the private garden. We checked Schaan and Vaduz in full text; for the other municipalities ask the municipal administration.
- The building notification can carry conditions: if your renovation is notifiable or permit-required, the authority can set building hours and noise conditions as a requirement. Larger sites are subject to stricter requirements than drilling one dowel hole.
- Neighbour law applies always (Art. 67 SR): all excessive effects on neighbouring property are forbidden, expressly including noise. Anyone who keeps the hours but disturbs massively and permanently can still be sued for an injunction and damages.
- The Swiss dB values do not bind automatically: the Construction Noise Guideline with its planning and exposure values is a Swiss enforcement aid. German "10 pm rules" and Swiss reference values are often quoted, but are not Liechtenstein law — here the LSV and the municipal regulation count.
🔓 Exceptions
- Tenancy: reduction rather than mere annoyance: if the landlord renovates and the flat is thereby less usable, a rent reduction comes into consideration; larger works must be announced in advance. Conversely, a tenant who disturbs permanently risks termination for breach of the duty of consideration.
- Municipal exemption permits: for urgent or larger works — including on a Sunday or at night — the municipality can grant an exemption permit. Without it, the building hours of the regulation apply.
- Only three of eleven municipalities checked: verified are Schaan and Vaduz in full text, and Triesen as having no regulation for private noise. For the other eight municipalities there is no confirmed statement — the time is in your municipal regulation, not in a national law.
⚠️ Penalties & fines
Anyone who ignores the building hours risks a municipal police fine — in Schaan up to CHF 2,000 through the mayor, in Vaduz from CHF 200 to 2,000, plus decision and procedural costs. Independently of that, the neighbour can sue under Art. 67 SR for an injunction and damages, even if you formally keep the hours. If your renovation is notifiable or permit-required and you breach the noise conditions, the authority can go as far as a construction stop — properly expensive on a running site. Not obvious: for tenants the greater danger is not the fine but repeated disturbance as a ground for termination; for landlords, the rent reduction if the renovation devalues the flat.

❓ Frequently asked
From when must I stop the noise during renovations?
There is no national law on this; the building hours of your municipality govern. In Schaan, for example, noisy construction work is forbidden from 12 to 1 and from 7 pm to 6.45 am — for other municipalities ask the municipal administration.
Do the Swiss dB reference values for construction noise apply here?
No, the Construction Noise Guideline with its planning and exposure values is a Swiss enforcement aid. In Liechtenstein the Noise Abatement Ordinance and the respective municipal regulation govern, not the imported reference values.
My landlord is renovating the building — can I reduce the rent?
If the flat is noticeably less usable because of the works, a rent reduction comes into consideration. Larger renovations must also be announced by the landlord in advance so that you can prepare for them.
May I renovate or drill on a Sunday?
That depends on the regulation of your municipality, and many of them forbid noisy work outside certain daytime windows. For urgent or larger works the municipality can grant an exemption permit, but without it the ordinary building hours apply.
What can I do if the neighbour makes constant construction noise?
You can involve the municipality, which can impose a police fine on the person responsible, and you can rely in civil terms on Art. 67 SR. An injunction and damages are then possible whenever the noise amounts to an excessive effect on your property.
