What are mold and damp?

Mold is a type of fungus that thrives in damp environments and can appear as stains or discoloration. Damp problems can be caused by leaks, poor ventilation or condensation. Long-term damp can damage building materials and affect indoor air quality.

In most cases, renters are entitled to a basic standard of housing.

Health risks

Mold and damp damage can cause different symptoms depending on exposure and sensitivity. Common problems are airway irritation, coughing, allergic reactions and worsened asthma. Certain groups such as children, the elderly and people with weakened immune systems are more sensitive.

  • Breathing difficulties, coughing and mucous membrane irritation.
  • Allergic reactions like itchy eyes and nasal congestion.
  • Worsened asthma or chronic respiratory conditions.
Seek medical care if you experience breathing problems or severe irritation.

What can the renter do?

As a renter you should first report the problem to the landlord in writing and request that repairs are made within a reasonable time. If the landlord does not respond or does not fix the issue, you can document it and take the next step by contacting the rent tribunal.

  • Make a written fault report to the landlord and keep a copy.
  • Request a clear schedule for repairs and remedial actions.
  • Document damage with photos, dates and descriptions.
  • Keep receipts for any costs you had for temporary measures.
Always write date and description when you send a fault report.

Documentation and evidence

Good documentation is often decisive. Take multiple photos from different angles, write dates and times, and keep a simple log of smells, visibility and symptoms. Do not limit documentation to a single photo; update when the situation changes.

  • Photos with timestamps and short notes about where the photo was taken.
  • Logbook of symptoms and how often problems occur.
  • Receipts and communication with the landlord kept as evidence.

When to contact authorities

If the landlord does not take action, the rent tribunal can review the case under the Swedish Land Code, Chapter 12, which governs rent and housing standards [1]. For formal applications and forms use the rent tribunal services on domstol.se [2]. If enforcement or collection of a decision is needed, the Enforcement Authority (Kronofogden) may be involved [3].

Detailed documentation improves your chances of success in a dispute.
