Effects of short-term rentals on local housing markets


The Sharing Economy has gained increasing economic and social importance. Today it touches our lives in fundamental ways, including housing and the housing market. Housing stock that was once intended for long-term residents of the city is now being used as holiday homes and rented out to tourists, visitors and travelers on a short-term basis. Especially in times of urban growth, rising rents and tight housing markets, this development contributes to an increasing urban housing challenge. The specific conditions and developments in the cities mean that the Sharing Economy is developing differently in each city. In this context, some cities take individually adapted measures to control the extent of the Sharing Economy in the context of the respective housing market. Lack of reporting by Airbnb and other short-term rental providers, as well as supply and demand volatility, are together with the global real estate market the cause for some of the many obstacles which cities face in analyzing and responding effectively to development of short-term rentals.

This project therefore focuses on the interaction of short-term rental in the housing market and the measures taken by cities to achieve balance and control, as well as the question how to measure the efficiency of such measures. Of conceptual interest here is also the extent to which “swarm phenomena” such as virtual platforms with a direct access to the distribution of resources with physically limited markets - in this case the housing market - can be reconciled with the strategic goals and planning actions of the cities by means of the existing instruments of planning control. Hereby, seven German cities are compared, followed by nine other European cities. The research program includes a quantitative in-depth analysis of the housing market, population and tourism data. Based on this, the extent of short-term rentals on the local housing markets are being explicitly determined with the help of collected data on Airbnb rentals. By means of a QCR-supported comparison of the case study cities, the extent to which the measures taken are suitable for the effective regulation of short-term rentals in the short and long term will be evaluated. On the one hand, this will lead to a better insight into the different forms of regulation and recommendations for future measures. On the other, we want to contribute to the general discourse on the planning control possibilities of the Sharing Economy.


Airbnb and Co. - The business of sharing

The original idea of sharing a couch space that has become temporarily vacant is increasingly being transformed into a professional business model in which individual rooms and apartments are rented out on a daily or weekly basis throughout the year. The authors from the ILS research group "Spatial Planning and Urban Development" and from the Technical University of Dortmund are therefore investigating the questions of what influence such short-term rentals have on urban structures, how the corona pandemic is affecting this market, and what regulatory and action options exist for cities.

Most cities in the major agglomerations in Europe started to cope with the rise of the accommodation short-term rentals by regulations in order to protect their local housing stock. The introduction momentum of such regulatory approaches can be attributed to different causes. This article examines various fields related to short-term rentals in order to uncover (structural) triggers or conditions that are necessary and sufficient for municipalities to start regulation for their housing market. The study is based on the systematic examination of the effects of those triggers and their combinations on the introduction of short-term rentals regulations using qualitative comparative analysis (QCA). With this method, we explore the implementation or non-implementation of regulation for a sample of the major German cities. The results suggest a universal set of conditions covering three central fields: housing market situation, accommodation market conditions and tourism accommodation demand.
