The goal is to give you clear options to secure your home and resolve disputes early. We also explain how to use official forms, which evidence is useful in court and where to find free advice.

What does "local comparative rent" mean?

The local comparative rent is a market-based benchmark derived from housing offers in the same area with similar amenities and construction year. It serves to assess whether a requested rent increase is reasonable. Details on legal texts and definitions can be found in the relevant provisions of the MRG.[1]

The comparative rent is based on real comparable properties in the area.

Tenant rights for rent increases

Tenants have the right to review the calculation of a rent increase and to request a written justification. Unclear or non-transparent increases can be contested. Pay attention to the deadlines stated in the notice and document the provided comparable properties.

  • Check deadlines and ensure they are met.
  • Request a written justification and details of comparables.
  • Collect evidence: listings, condition, photos.
  • If necessary, file an objection or seek judicial clarification.
Respond to legal notices within deadlines to avoid losing rights.

Repairs and maintenance

As a tenant, you can demand necessary repairs when the apartment has defects such as lack of heating or water damage. Always report defects in writing, set a reasonable deadline for remediation and document the damage carefully with photos and witnesses. Keep all correspondence and receipts to provide evidence if needed.

Keep all rent payments and defect reports stored together and accessible.
