Water coming through the ceiling from the flat above: what the law says in 7 jurisdictions
Water from the flat above ruined your ceiling and the neighbour says it is not his fault. Italy, France, Germany and Spain each answer with a different rule on fault and proof; England, California and New York have no statute at all.
The problem
Water appears on the ceiling, the wall stains, the floor swells and the furniture is ruined. The water is coming from the flat above. The neighbour says the pipe went on its own, that he did nothing, that it is not his fault, and refuses to pay. Nobody disputes where the water came from; what is disputed is whether the neighbour has to pay for something he did not do on purpose and did not notice in time.
What they agree on
In all seven jurisdictions this is a claim between two people who have no contract with each other. The upstairs neighbour did not promise the downstairs neighbour anything, so the claim runs on the law of civil wrongs — delitto, delit, unerlaubte Handlung, culpa extracontractual, tort — and not on any agreement. That has one consequence everywhere: nothing in the lease, the deed or the building rules decides the case between the two flats.
Everywhere, too, the person who has to pay is not automatically the person on the title deed. Each of the four codes that answers this question points at whoever had the thing under their control, or whoever lived in the flat, rather than at the registered owner as such. In a rented flat that means the tenant can be the defendant for what is in their own use while the landlord answers for the structure and the risers, and the split between them depends on the facts and on the tenancy, not on a rule that can be stated in advance. The three common-law sections reach the same place by a different route: the defendant is whoever owed and breached a duty of care.
And everywhere the real fight is technical rather than legal. Every one of the seven systems requires the injured party to prove that the water came from that flat and caused that damage, and in every one of them the case is usually won or lost on a survey done early, on photographs taken while the ceiling is still wet, and on whether a buildings or block insurance policy was notified in time. What differs between the seven — and it differs a great deal — is what has to be proved beyond that, and by whom.
Where they part company
| Jurisdiction | What its law does | Why it matters |
|---|---|---|
| Italia | Art. 2051 imposes liability on whoever has the thing 'in custodia' and lets him out only if he proves 'caso fortuito' — an outside event, unforeseeable and unavoidable. The injured neighbour proves the damage and that it came from a thing; he does not prove carelessness. | The whole case turns on a defence the defendant has to establish. 'I did not know the pipe was corroded' is not caso fortuito; it is exactly the kind of ignorance the article refuses to excuse. This is why almost every Italian infiltration dispute is pleaded under art. 2051 rather than under the general fault rule of art. 2043. |
| France | Art. 1242 uses the same structure — responsibility for 'les choses que l'on a sous sa garde', with no fault to prove — but the same article carries a written exception for fire: whoever holds the building where a fire started answers to third parties only if his fault is proved, and the text says that exception does not apply between landlord and tenant, who stay under arts. 1733 and 1734. | One article contains two opposite regimes. Water escaping is strict; fire spreading is fault-based against a neighbour and strict again against your own landlord. Damage from firefighting water after a fire upstairs is therefore argued on a different footing from the same water arriving from a burst pipe. |
| Deutschland | Germany is the outlier among the four codes. § 823 requires 'vorsätzlich oder fahrlässig' — intention or negligence — and there is no general German liability for things one keeps. The functional substitute, the Verkehrssicherungspflicht, is judge-made and sits inside the fault analysis rather than replacing it. The one BGB provision that does reverse the burden, § 836, covers the collapse of a building or the detachment of parts of it, not a leak. | The downstairs neighbour in Germany has to show that the upstairs one failed to take a precaution a careful person would have taken — an unserviced boiler, a known drip left alone, a washing machine hose never replaced. A pipe that failed without warning inside the wall can leave the loss where it fell. Anyone who reads 'the civil codes are strict, the common law is not' has already got Germany wrong. |
| España | Art. 1910 makes 'el cabeza de familia que habita una casa o parte de ella' answerable for damage from things thrown or fallen from it. The person named is the one who lives there, not the owner, and no fault is required — it is not even necessary to establish who inside the flat let the thing fall. Case law has extended 'things that fall' to water and liquids. | The choice of defendant is written into the text, and it is the occupier. A landlord who lets the flat and lives elsewhere is outside art. 1910 on its own words. If instead a piece of the building itself came away — a cornice, a slab of facade — the article is 1907, which points at the owner and only 'si esta sobreviniere por falta de las reparaciones necesarias', which reintroduces fault. |
| Spain's limitation period is one year. Art. 1968.2 gives one year for the action under art. 1902, running from when the injured party knew. Italy allows five years from the event (art. 2947), France five years from the day the claimant knew or should have known (art. 2224), Germany three years running from the end of the calendar year in which the claim arose and the creditor learned of it (§§ 195 and 199). | The spread is one year to five, and the starting points are not the same either. A Spanish claim can be out of time before a damp survey has finished and before the drying-out has revealed the full extent of the damage, while an identical Italian one still has four years to run. Anyone in this situation should check the limit that applies to them with a lawyer in that country before anything else. | |
| United Kingdom | None of the three English-language sections has a statute for water arriving from the flat above. The claim is negligence, private nuisance, or the rule in Rylands v Fletcher, and all of them are judge-made. | That is not a drafting accident, it is the substantive difference. In England, California and New York the injured neighbour normally has to prove that somebody failed to take reasonable care. In Italy, France and Spain the corresponding article puts the burden the other way round. Same facts, opposite starting position. |

Where there is no answer in the code
A jurisdiction listed here is a finding, not a gap. Either its answer lives outside the corpus — special legislation, case law, municipal rules — or its law simply has no such rule.

United Kingdom
The courts answer it
Negligence, nuisance, Rylands
There is no Act of Parliament on water escaping between flats. A leak from upstairs is negligence, private nuisance or Rylands v Fletcher, all developed by the courts. The statutes the lookup reached for — LTA 1985 s. 11 and EPA 1990 s. 79 — answer the different question of a tenant against a landlord, or of a statutory nuisance against a local authority, not of one flat owner against another.
-
California
The courts answer it
Negligence
California has a general duty clause, Civ. Code § 1714, and a nuisance definition, § 3479, and neither is a rule about escaping water. They set the frame in which a negligence claim is argued; they do not decide who bears the loss when a pipe fails.
-
New York
The courts answer it
Common-law negligence
Same. The statute the lookup produced, RPL § 235-b, is the warranty of habitability, which the § 235-b page itself points out speaks only to the landlord's obligation under the lease: 'If a neighbor's plumbing caused the damage, § 235-b still speaks only to the landlord's obligation.' Neighbour against neighbour is common-law negligence.
