Mietspiegel

Mietspiegel is a local rent index used in Germany to determine the customary rent for residential properties in a specific city or district. It provides a benchmark for the “ortsübliche Vergleichsmiete” (local comparable rent) and is commonly used in rent negotiations and disputes to assess whether a rent is reasonable.

Creation and scope

Mietspiegel are typically prepared by municipalities, districts, or tenants’ associations. They follow a defined methodological framework and are based on a representative survey of actual rents for comparable dwellings. The accounts usually take into account factors such as location, type of building, year of construction, living space, number of rooms, and equipment or standard of finish. There are different forms, including the so-called “qualifizierter Mietspiegel” (qualified rent index), which is based on a statistically sound survey and is considered more robust in court. Mietspiegel are updated regularly, often every one to two years, to reflect current market conditions.

Usage and legal significance

In tenancy law, landlords may adjust rents within the limits indicated by the local Mietspiegel, and tenants can use it as a reference to assess proposed increases. If a recognized Mietspiegel exists and is up to date, it generally serves as the primary yardstick for determining the permissible rent range. In the absence of a Mietspiegel, other methods for determining reasonable rent may be used, such as benchmarking against comparable properties or other accepted references. While Mietspiegel guide rent levels, they do not automatically fix rents; disputes may be resolved in court where the Mietspiegel is weighed as evidence.

Access and limitations

Mietspiegel are publicly published by municipalities, districts, or tenants’ associations and are typically available online or in printed form. Their relevance is regional; a Mietspiegel valid for one locality may not apply to neighboring areas. The accuracy of a Mietspiegel depends on the quality of the underlying survey and the timeliness of updates.
