The email from the syndic, the building’s managing agent, arrives on a Tuesday. The owner of the flat below yours in Antibes says she now hears every footstep through her ceiling. It started when the old carpet was replaced with tiles, a job your agent arranged while you were at home in Manchester. She wants the floor soundproofed, and she says the law is on her side.
She may be right. French law can force an owner to soundproof a home, but only under conditions, and the courts draw the line in places an owner abroad wouldn’t expect. The government’s guidance on the question, checked on 23 October 2026, sets out the principle in a few lines. We’ve gone back to the texts and the rulings behind it, and added what the guidance leaves out: the building standards, two Cour de cassation decisions that mark the boundary, the route from complaint to court order, and a checklist for anyone renovating a French flat from a distance.
Sources: order of 30 June 1999 on the acoustic characteristics of residential buildings, articles 2 and 4, and the government’s guidance on airport soundproofing grants.
When the law can make an owner soundproof
The legal basis is the trouble anormal de voisinage, a disturbance that goes beyond the normal inconveniences of living next to other people. French courts applied that principle for decades before Parliament wrote it into article 1253 of the code civil in April 2024. Whoever is at the origin of the disturbance is liable for the damage it causes, and the victim doesn’t have to prove any fault. That person can be the owner, the tenant, an occupier without any right to be there or whoever commissioned building works.
In a copropriété, a building divided into privately owned flats with shared parts, the guidance says an owner can be made to soundproof once such a disturbance is established. It gives four typical causes:
- the flat’s acoustic insulation doesn’t meet the standards that apply to it
- the noise goes beyond what’s normally tolerated when people live together in one building
- a floor covering has worn out
- a new floor covering has seriously degraded the acoustic insulation. Judges have held, for instance, that replacing carpet with tiles harmed the other owners’ rights because impact noise rose sharply.
The 2024 text adds one exception. There’s no liability where the disturbance comes from activities that already existed when the victim bought or moved in, provided they comply with the law and haven’t changed in a way that made the disturbance worse. The exception is about activities, such as a farm or a business, and the text says nothing about a change of flooring.
Meeting the building standard isn’t always enough
Homes built under a permit filed from 1 January 2000, and extensions or added storeys on older buildings applied for from that date, must meet minimum acoustic levels set by an order of 30 June 1999. Between one home and the main room of another, airborne sound insulation must reach at least 53 decibels, or 50 for a kitchen or bathroom. Impact noise, meaning footsteps and dropped objects heard from another home, mustn’t exceed 58 decibels in any main room. Buildings permitted before 2000 were built to the rules of their own time, and these figures don’t apply to them.
| What is measured | Standard | Which buildings |
|---|---|---|
| Airborne sound from another home into a main room | At least 53 dB of insulation | Permit filed from 1 January 2000 |
| Airborne sound from another home into a kitchen or bathroom | At least 50 dB of insulation | Permit filed from 1 January 2000 |
| Impact noise (footsteps, dropped objects) in a main room | No more than 58 dB | Permit filed from 1 January 2000 |
Meeting those figures doesn’t settle the matter. In a ruling of 15 January 2003, the Cour de cassation upheld an order against a sixth-floor owner who had replaced the carpet in his living room and bedroom with floating parquet, and the cork-backed ceramic tiles in his kitchen and bathroom with a different ceramic. The owner below complained of the noise, and after a court expert’s report the Douai court of appeal ordered him to carry out soundproofing works.
His new floors were within the regulatory values. They still insulated less well than the ones he had taken out, and the règlement de copropriété, the building’s binding rulebook, required each owner to keep the building quiet and make no noise likely to disturb the neighbours. That was enough. For an owner abroad, the lesson is that the benchmark can be the floor you removed, and the building’s own rules can be stricter than the national standard.
The line runs the other way too. In a ruling of 19 May 2016, the same chamber rejected a neighbour’s appeal in a Paris case. The owners upstairs had soundproofed their sixth-floor flat before moving in, and the woman below had even contributed to the cost. She still heard them and sued for damages. The court of appeal found she was hearing the ordinary sounds of daily life in an old building that had been poorly insulated from the start, with no excessively noisy behaviour, and the Cour de cassation left that assessment to the trial judges.
From complaint to court order: the four steps
Step 1: talk first, and put any agreement in writing
The person suffering the noise, whether a tenant or an owner, and the owner of the flat it comes from can agree between themselves on the soundproofing works to be done. Write the agreement down: what will be done, by whom, by when and who pays. If the règlement makes floor works subject to the syndic‘s or the general meeting’s approval, get it before anything starts.
Madame, Monsieur,
Depuis le remplacement du revêtement de sol de votre appartement, situé au-dessus du mien (lot n° [ ]), en [mois et année], les bruits d’impact sont devenus nettement plus forts dans mon logement : pas, chutes d’objets, déplacements de meubles. Je joins [le relevé daté des nuisances / le rapport de l’acousticien / le constat du commissaire de justice].
Je souhaite trouver avec vous une solution amiable, par exemple la pose d’une sous-couche acoustique ou de tapis dans les pièces concernées, et je vous propose d’en discuter d’ici le [date].
À défaut d’accord, je saisirai le conciliateur de justice, puis, si nécessaire, le tribunal judiciaire.
Veuillez agréer, Madame, Monsieur, l’expression de mes salutations distinguées.
In English: since you changed your floor in [month], impact noise in my flat has risen sharply, and the evidence is attached. I’d like to agree a fix with you, such as an acoustic underlay or rugs, by [date]. If we can’t agree, I’ll go to the court conciliator and then, if needed, to court.
Step 2: gather the evidence
A judge will want proof that the noise is abnormal, so start collecting it early. Keep a dated log of the disturbances and ask other neighbours for written statements. A report by a commissaire de justice, the public officer whose findings carry legal weight, records the facts on a given day. An acoustician can measure the impact noise and set it against the standards above. Under the companion order on testing methods, those measurements are taken in furnished rooms with the doors and windows closed. If you live abroad, a local agent or a neighbour can let the professionals in, but make sure the instructions and the reports come to you.
Step 3: try conciliation
Before a claim about an abnormal neighbourhood disturbance can go to the tribunal judiciaire, the local civil court, the parties must first try conciliation, mediation or a participatory procedure, under article 750-1 of the code de procédure civile. The text lists a few exceptions, and the judge can throw out a claim that skipped this step. The usual route is a conciliateur de justice, a volunteer appointed by the courts, whose help costs nothing.
Step 4: ask the court to order the works
If conciliation fails, the victim can ask the court for a decision imposing the soundproofing works. The judge can order the owner responsible for the noise to carry them out and, where necessary, attach an astreinte, a financial penalty that keeps running until the order is obeyed. Damages for the disturbance already suffered can be claimed as well. What the judge can’t do is make the victim pay for and carry out soundproofing in their own home to make up for the disturbance.
Tenants: what you can and can’t ask your landlord
A tenant disturbed by noisy neighbours can’t require the landlord to soundproof the flat. Acoustic insulation isn’t among the criteria of a logement décent, the decent-home standard a landlord must meet when letting someone’s main home, set by a decree of 30 January 2002. Under article 6 of the law of 6 July 1989, the landlord must let a decent home, ensure the tenant’s jouissance paisible, or quiet enjoyment, and keep the property in repair. Soundproofing isn’t on that list. The tenant’s route is against the source of the noise, because a tenant who suffers an abnormal disturbance can pursue the neighbour responsible, just as an owner can.
For a landlord abroad, this cuts both ways. You can decline a tenant’s request to soundproof against the neighbours, although a modest fix may be worth paying for to keep a good tenant. If the complaint is about noise coming from your flat, the position changes, because article 1253 reaches the occupant and the owner alike. We explained what to do in that case in our guide for landlords whose tenant is the noisy one.
Aircraft noise: a grant instead of a lawsuit
If the noise comes from the sky, a different system applies. Homes near 11 major airports can get a soundproofing grant paid by the airport operator: Bâle-Mulhouse, Beauvais-Tillé, Bordeaux-Mérignac, Lyon-Saint-Exupéry, Marseille-Provence, Nantes-Atlantique, Nice-Côte d’Azur, Paris-Charles de Gaulle, Paris-Orly, Paris-Le Bourget and Toulouse-Blagnac. The home must lie in one of the three zones of the airport’s plan de gêne sonore, its noise-exposure plan, where zone I is the noisiest. The grant also covers the acoustic study, which you pay first and get refunded once you send the report and the invoice.
The expenses taken into account are capped. In a flat, the cap is €2,500 per room in zone I, €2,310 in zone II and €1,900 in zone III, with lower caps for the kitchen (€2,310, €1,720 and €1,345). In a house, the roof counts for a flat €6,250 in every zone and each room for up to €4,375, €4,000 or €3,625. The grant is a share of those costs at a rate that depends on your situation. In a copropriété, it can also cover the preliminary studies, the ventilation work that soundproofing makes necessary and the syndic‘s fees, up to 2% of the works before tax.
You apply to the operator and send the acoustic study and a contractor’s quote by recorded delivery, and a residents’ advisory committee gives its opinion before the operator decides. Once the grant is approved, the works must be done within two years, and the money is paid when they’re finished, on the invoices. The caps are tripled for social housing built before 1960 that lies entirely in zone I or II and falls within an urban renewal agreement.
Before you change the floors from abroad
Both rulings in this article began with renovation work. If you’re having work done on a French flat while you live elsewhere, these steps cost little and can save you a court order:
- Read the règlement de copropriété for clauses on floor coverings, noise or acoustic performance, and check whether the works need the syndic‘s or the general meeting’s consent. Our guide to the copropriété general meeting explains how the agenda and the votes work.
- Ask your contractor, in writing, for a covering laid on a sous-couche acoustique, an acoustic underlay, and keep the product data sheets and the invoices.
- Treat the floor you’re taking out as the benchmark. If the old carpet or cork-backed tiles were quieter, the 2003 ruling shows that meeting the national standard may not protect you.
- Tell the neighbour below before the works start, and leave a contact number. A warning can head off a complaint.
- If a tenant asks to change the floors, answer in writing and set the same conditions.
- When buying, ask the seller in writing whether the floors have been changed and whether any neighbour has complained about noise, and have the answers recorded in the compromis, the preliminary sale contract. Our buying guide covers the other checks.
If you manage the flat through an agent, add these points to their brief. Our guide to managing French property remotely covers working with a local agent.
Where you stand
Your floor is the source and the neighbour has evidence: negotiate early. A court can order the works under an astreinte, and a losing owner can be made to bear the costs of the case, including the court expert’s fees.
You’re the one hearing it: gather evidence, write, try conciliation, then go to court. You can’t be made to soundproof your own flat instead.
Your tenant wants you to soundproof against the neighbours: you aren’t obliged to, because acoustics aren’t part of the decent-home standard.
The building is old and the noise is everyday life: the 2016 ruling shows such a claim can fail, so weigh an amicable fix first.
You’re near one of the 11 airports: check the noise-exposure plan before paying for soundproofing yourself.
Our view
We think the 2003 ruling is the part owners most underrate. Measuring a new floor against the old one is fair to the neighbour below, who bought into a building with a certain level of quiet. It also means an owner can follow the national standard to the letter and still be ordered to do costly works, on a benchmark that may never have been written down before the old floor went into a skip. A photo of the old floor and a copy of the new underlay’s data sheet are cheap insurance.
The tenant side is harder to defend. Noise affects sleep and health, yet acoustics are absent from the decent-home criteria, so a tenant’s main lever is a claim against a neighbour they didn’t choose and may never have met. A landlord can’t be forced to help. A sensible one may, because a tenant who leaves over noise can cost more than a few rugs.
Readers, have you ever had a neighbour in France change their floors, and did the noise change with it? If you’ve renovated a French flat from abroad, did anyone check the règlement before the new floor went down? Would you pay for an acoustician before complaining, or only once it reached court?
FAQ: soundproofing and neighbours in France
Can a neighbour force me to soundproof my flat in France?
Yes, if a court finds an abnormal neighbourhood disturbance coming from your flat, for example after a change of flooring that sharply increased impact noise. The judge can order the works and attach a financial penalty for delay. You and the neighbour can also agree on the works without going to court.
Is meeting the French acoustic standard enough to protect me?
Not necessarily. In a ruling of 15 January 2003, the Cour de cassation upheld an order to soundproof where new floors met the regulatory values but insulated less well than the originals, and the building’s rules required owners to avoid disturbing noise.
Can my tenant make me soundproof the flat?
No. Acoustic insulation isn’t among the decent-home criteria a landlord must meet. A tenant disturbed by neighbours can pursue the neighbour responsible for the noise.
Is there financial help for soundproofing near an airport?
Yes, near 11 major French airports. The airport operator can fund soundproofing for homes in the zones of its noise-exposure plan, within caps per room (up to €2,500 per room in a flat in zone I), and also refunds the acoustic study.
