Where to start
Establish exactly where people smoke, how smoke enters the apartment, when it happens and whether it recurs. Preserve the facts before making a complaint.
Documents to prepare
Collect an incident chronology, reports and responses, photos, video, correspondence and witness information. Do not publish materials containing others’ data without a legal basis.
Available measures
Depending on the location and evidence, options include contacting the police or property management organisation, a formal demand and court protection. Ventilation may require a specialist’s inspection.
