• Send a written defect notice to the landlord, by email and registered mail if possible.
• Check ventilation and heating behavior and document briefly.
• If health problems occur, consult a doctor and document findings.^[2]

Rights and obligations

Landlords are obliged under § 535 BGB to maintain the rental property in a condition suitable for use.^[1] Tenants must report defects and have rights to rent reduction, damages or subsequent performance by the landlord in case of significant impairment.

If a dispute arises, the local district court (Amtsgericht) is responsible for many rental disputes; lawsuits can be filed there if out-of-court agreements fail.^[3] Before filing a lawsuit, it is advisable to seek advice from a tenants' association or a specialist lawyer.
