Your upstairs neighbor left a tap running, a washing machine hose burst, or an old faucet finally gave out — and now water is running down your walls, ruining wallpaper, warping the floor, dripping onto a fresh renovation. The neighbor shrugs: “I didn’t do it on purpose.” The management company says “call the neighbor, it’s not our pipe.” Who’s actually required to pay for water damage — the neighbor upstairs or the management company? Here’s exactly how Russian law assigns liability, what evidence you need, and how to document everything properly so you get paid instead of excuses.
Who’s liable: the neighbor or the management company
The first legal point that decides liability is exactly where the pipe failed. All plumbing in a building splits into common property and property belonging to a specific apartment. The boundary is the first shut-off valve on the riser pipe (Government Resolution No. 491): everything before the valve, including the riser itself, is common property — the management company is liable. Everything after the valve is part of the apartment — the owner is liable.
- If the riser burst or a pipe failed before the first shut-off valve — that’s common property, the management company is liable.
- If a washing machine hose, faucet, or tap inside the apartment failed, or the neighbor left a tap running — the apartment owner (the neighbor) is liable.
In practice, most flooding happens for reasons inside the apartment: aging flexible hoses, faulty faucets, a tap left open. That’s the neighbor’s liability, not the management company’s.
Important clarification about radiators and towel warmers: these have a different status. Under Government Resolution No. 491, heating elements are included in common building property without the “first shut-off valve” carve-out that applies to water supply. So in most cases, a leak through a radiator or towel warmer is the management company’s liability, not the apartment owner’s — unless it has an individual shut-off valve allowing it to be disconnected from the building-wide system (in which case it may be treated as the owner’s personal property). This point is frequently disputed in court, and the exact classification depends on the technical specifics of that building’s heating system.
If the owner replaced the radiators themselves, the radiator’s status as common property usually doesn’t change — swapping the physical unit doesn’t turn a building-wide system into personal property as long as the connection method stays the same (through the riser, without an individual shut-off valve). But if the leak was caused specifically by poor installation during the replacement — bad welding, an incorrect threaded connection — liability falls on the owner: they caused the harm through their own actions, regardless of the radiator’s formal status.
A separate case is underfloor heating or heating built into the walls. If it’s a separate loop installed by the owner inside the apartment, not connected to the building’s shared riser, it’s the owner’s personal property, and they’re fully liable for its condition. If the built-in system draws from the shared heating riser without the ability to be disconnected, the same logic as ordinary radiators applies — the management company is liable. But if such a system resulted from unauthorized reconfiguration (for example, radiators replaced with underfloor heating without approval from local housing inspectors), that’s a separate basis for full owner liability — regardless of what caused the leak.
How Russian courts handle water damage cases
The key question is whose fault caused the failure. Article 1064 of the Civil Code: whoever caused harm is liable for it. Three scenarios:
1. The flood happened because of the neighbor’s negligence
If the neighbor left a tap running, never replaced an aging washing machine hose, or did renovation work that violated code — that’s negligence. Liability is full, regardless of whether it was “on purpose” or not.
Russian courts consistently hold the apartment owner fully liable when the cause of the flood is located inside their apartment — past the first shut-off valve. “I didn’t mean to” is not a defense.
2. The flood happened because of shared building plumbing
If the riser burst, a pipe failed before the shut-off valve, or the cause was worn-out common building plumbing — the management company is liable, since it’s responsible for maintaining that plumbing (Article 161 of the Housing Code).
3. The flood happened due to an unforeseeable defect (almost never accepted)
To qualify as force majeure, the event must be unforeseeable and unavoidable even with proper care. A hidden manufacturing defect in a pipe that couldn’t have been detected visually might theoretically qualify — but in practice this is extremely hard to prove, and the court will typically require expert confirmation that it was a genuine manufacturing defect rather than ordinary wear from years of use.
What evidence matters: how courts decide liability
Critical document — the water damage report (акт о заливе). This is the single most important piece of evidence in a flooding case, more important than witness statements. The report is drawn up by a representative of the management company (or homeowners’ association) in the presence of the injured party and, ideally, the party at fault — usually within 1–3 days of the request. It records: the date and time of the flood, the cause (if identifiable on site), the nature of the damage, and which rooms were affected. Without this report, proving the cause and extent of damage in court becomes significantly harder.
How to get the report: as soon as you discover the flood, call the emergency service or management company (the number is usually on your utility bill or posted in the stairwell), report the flood, and request that a representative be sent to draw up the report. If the management company delays or refuses, send a written request demanding the report — this creates evidence that you asked.
- The water damage report — the primary document described above.
- Photos and video of the damage — taken immediately, before any repairs begin.
- Independent damage assessment — a structural/technical expert report calculating the exact cost of the damage. Without it, your demand letter and lawsuit have no financial foundation.
- Witness statements — from neighbors who saw the aftermath of the flood or can confirm its source.
How to proceed if you’ve been flooded
Step 1: document the flood and call the emergency service As soon as you discover the flood, photograph the damage and call the management company or building’s emergency service. Insist on a water damage report being drawn up. If the apartment is insured, call your insurance company right away too — most policies require an inspection of the damage before repairs begin, and delaying that call can become grounds for denying the claim.
It’s worth inviting an independent expert to this same inspection, rather than waiting for a separate visit later (see Step 2a): that way they document the extent of the damage and the likely cause of the leak in its original state — before the damage dries out or repairs begin. This matters especially if the management company itself could end up being the defendant: its own report isn’t always an objective document, while an independent assessment records the scene regardless of what the management company’s report says.
Step 2: wait for the water damage report The management company is required to draw up the report within a reasonable time (usually 1–3 days). Check that the report records the cause of the flood, not just the fact of the damage.
Step 2a: order an independent damage assessment Bring in an independent expert before starting repairs — they’ll document the extent of the damage and calculate the amount. The expert’s report becomes the main evidence of damage amount in court.
Step 3: send a formal demand letter Write to the neighbor or the management company, whichever is at fault. In the letter:
- Describe what happened, referencing the water damage report
- State the damage amount per the expert assessment
- Attach photos and the expert’s report
- Give 10 days to pay voluntarily
Step 4: if they refuse — sue The statute of limitations is 3 years (Article 196 of the Civil Code), but don’t wait — the longer you delay, the harder it is to prove causation.
How Russian courts handle these cases in practice
The neighbor’s liability: Courts establish that an apartment owner is liable for flood damage caused by something inside their apartment, unless they can prove otherwise.
Penalties for refusing voluntary payment: If the defendant is the management company, the Law on Consumer Protection applies in full: for refusing to pay voluntarily, courts award a penalty of 50% of the awarded amount (Article 13(6) of the Consumer Protection Law). If the defendant is the neighbor (a private individual), the Consumer Protection Law does not apply (this is a dispute between citizens under Article 1064 of the Civil Code), so no 50% penalty — only actual damages, court costs, and in some cases modest compensation for non-pecuniary harm.
Obligation to keep plumbing in working order: Even old flexible hoses or a worn-out faucet don’t excuse the owner from liability — they’re obligated to monitor the condition of equipment inside their apartment and replace it in time.
Can you avoid paying if it was “just an accident”
Very hard in practice. Courts don’t accept the mere fact that a flood was “accidental” or “unexpected” as an excuse — if the equipment was inside the defendant’s apartment, a presumption of fault applies: it’s the defendant who must prove they maintained the plumbing properly and the flood wasn’t due to their negligence.
When the management company pays, not the neighbor
If you can prove that:
- The failure happened on common building property (the riser, a pipe before the first shut-off valve)
- The management company failed to maintain or inspect the pipes
- The management company knew or should have known about the problem (previous leaks, resident complaints)
Then the management company is the defendant, and Consumer Protection Law rules apply, including the 50% penalty.
Frequently asked questions
If I have home insurance, does that let the neighbor or management company off the hook? No. Your insurer will pay you, then sue the party at fault directly (subrogation). Having insurance doesn’t release the responsible party from liability.
The neighbor won’t open the door, so the report can’t be drawn up — what do I do? The water damage report can be drawn up without the neighbor present — the management company records the fact and cause of the flood in the presence of the injured party and at least two witnesses (other neighbors, for example), noting that the responsible party was notified but did not appear.
I was flooded, but I rent my apartment — who claims the damages? The apartment owner files the claim (or the tenant, for damage to their own personal property — furniture, appliances, belongings). Talk to the owner about who will file which part of the claim.
The flood happened six months ago, and I only now decided to claim damages — is it too late? No, you have three years to sue (Article 196 of the Civil Code). But the longer you wait, the harder it becomes to prove the connection between the flood and the current state of your apartment — keep the water damage report and photos from the start.
