Flooded Czech rental: who pays and what should I do?

Water is running through the ceiling, a washing-machine hose has failed or a concealed pipe has soaked the wall. “The upstairs neighbour pays” may be wrong—or only one part of the answer. First control danger and preserve evidence. Then separate the source repair, damage to the landlord’s apartment, damage to your belongings and the cost of drying or living elsewhere.

Notify the landlord immediately, even if the water came from elsewhere

Civil Code section 2264 and current MMR guidance require the tenant to report damage or a defect the landlord must remove without delay and to do what can reasonably be expected to prevent further loss. Make a phone call for the emergency, then create a traceable written record with the time, location, current flow, known actions, photographs and access details.

Give access for necessary inspection and repair. A burst pipe can justify urgent entry when advance arrangement is impossible, but ask for an after-event record: who entered, when, why, what was opened or removed and what must happen next. See the emergency-entry and access guide.

Do not decide liability from the direction of the water

• Neighbour’s overflow, appliance or neglect: the occupant, owner and their liability insurer may be relevant, but causation and responsibility still need evidence.
• Concealed pipe, common riser or building system: the landlord, unit owner, building body, contractor or building insurer may need to handle different parts.
• Your appliance or an ignored leak: notify the landlord, building and your household/liability insurer; preserve the failed hose, valve or appliance for assessment.
• Roof, facade, rain or drainage: record weather and the entry route and request a building-level diagnosis rather than repeated repainting.
• Unknown source: act to stop loss while stating that cause and final responsibility remain unconfirmed.

The party arranging or paying for emergency work is not automatically the party finally liable. Do not sign an admission of fault or promise a specific amount before the source, ownership, policies and loss have been assessed.

Keep four separate damage ledgers

• Emergency and source: call-out, valve, pipe, appliance, opening a wall and the part retained for inspection.
• Apartment and building: plaster, fixed flooring, wiring, kitchen, doors, landlord-owned furniture and common construction.
• Your household: clothing, electronics, furniture, documents and other belongings, with owner, age, original evidence and realistic replacement or repair cost.
• Consequential costs: drying, moisture measurement, storage, laundry, extra electricity and necessary temporary accommodation, each with dates and receipts.

Label photographs by room and date. Keep the tenancy agreement and handover record, contractor reports, moisture readings, messages, invoices, bank evidence and any policy or claim number. Ask the source contractor to record what failed and why, not merely that a repair was completed.

Notify every potentially relevant insurer promptly

MMR distinguishes property insurance for the building and fixed parts from household insurance for a tenant’s belongings, and gives third-party damage as an example in its tenancy-insurance overview. Whether that loss is covered by a liability section, add-on or separate policy depends on the actual wording. The insured person, event, exclusions, deductible, limits and reporting deadline also come from each contract, so notify rather than guessing which insurer must ultimately pay.

Ask whether an inspection is required before disposal or repair, how to document labour and drying electricity, and whether emergency mitigation can proceed. An insurer’s initial payment does not by itself settle final legal responsibility among the neighbour, tenant, landlord, building or contractor.

Dry the construction, not just the visible surface

Ask for a written plan covering source repair, safe electrical inspection where needed, opening or removing affected materials, dehumidification, moisture readings, completion criteria and restoration. Repainting a wet ceiling can hide the evidence and allow mold or material failure to return. Link the follow-up to the moisture, mold and serious-defect workflow.

A notice you can send today

If the apartment cannot be used

Ask the landlord in writing which rooms are safe, what services work, the repair and drying timetable and whether temporary vacancy is necessary. MMR says that where a notified defect is not removed within a reasonable time, remedies can include repair, compensation, a reasonable rent reduction or, especially where the apartment is unusable, termination without notice. The right remedy depends on cause, severity, notice, access and evidence.

If you caused water damage to another apartment

Stop the source safely, warn affected occupants, notify your landlord and building, contact your insurer and preserve the failed part. Provide facts and access without inventing a cause or promising the claimant’s number. Request an itemised loss record and coordinate inspections so damaged construction is not repaired before the cause and extent can be documented.
