Critical Review of Public Policies for the Rehabilitation of Housing Stock: The Case of Barcelona

This article reviews rehabilitation programs in Barcelona, focusing on aspects such as the intervention model, actual public investment, and results. Programs of this type are not exclusive to Barcelona; however, similar examples can be found in other European cities, especially where European Union (EU) funding is present. After analyzing these models, we reached a series of general conclusions that may be of interest. Thus, an eminently practical and reflective analysis is presented, aimed at technicians and those responsible for the design of intervention policies in urban regeneration. Rehabilitation programs are increasingly focused on vulnerable settings, and in this context, the participation and service function of public administrations are particularly relevant. The general model for rehabilitation subsidies rarely takes into account the specific characteristics of disadvantaged urban settings, as the article will show. After analyzing the different policies presented in this research, we identified two essential requirements: detailed knowledge of the affected neighborhood, and ongoing evaluation of the development of programs—beyond simple management indicators—so negative effects can be corrected in time such as gentrification, real estate speculation, and other by-products that the intervention itself can promote. This study confirms that not all public investments have the expected results.
