How to Deal with Mold in a Rental Apartment
Imagine moving into an apartment that seems perfect at first glance. After a few months, dark patches start appearing on the bedroom walls.

Clients often ask: “Who is responsible for removing mold in a rental apartment?”, “Can mold be a reason to terminate the lease?”, or “What if my landlord claims it’s my fault?”. People search for terms like mold in rental apartment, landlord responsibility for mold, mold health risks in apartment. That’s why I’m writing this article – to explain how to handle the problem both legally and practically, and to help avoid lengthy disputes.

Tenant’s rights to demand remediation.
Steps to take if the landlord does not respond.
Possibility of terminating the lease due to mold.
Mold as a Defect in the Apartment
Under the Czech Civil Code, the landlord is obliged to maintain the apartment in a condition suitable for use. If mold develops due to construction defects, insufficient insulation, or poor waterproofing, it is considered a defect of the apartment that the landlord must remedy. The tenant has the right to demand repairs and, in some cases, a reduction in rent.
When the Tenant Is at Fault
If mold appears due to insufficient ventilation, drying clothes indoors, or other improper use of the apartment, the responsibility lies with the tenant. In such cases, the landlord is not obliged to cover the costs of mold removal and may even claim them from the tenant.
Steps to Address Mold Issues
Immediately inform the landlord in writing – ideally with photo documentation.
Set a deadline for remediation – for example, 14 days to begin resolving the problem.
Request a professional assessment – to determine the cause of the mold.
Negotiate a rent reduction – if the apartment cannot be fully used.
Consider terminating the lease without notice – if mold poses a serious health risk and the landlord fails to act.
Risks of Ignoring the Problem
For tenants: health problems, asthma, allergies, and the possibility of having to pay for mold removal if they caused it.
For landlords: potential lawsuits, claims for damages, loss of tenants.
Lawyer’s Advice
💡 Do not underestimate the importance of evidence – always keep records of communication and photos.
💡 If the dispute escalates, have a formal legal notice drafted – it often prompts quick action from the other party.
💡 I recommend including clear rules for ventilation, heating, and apartment inspections in the lease agreement.
