Housing shortage is a prevalent problem in Sweden. The supply of housing does not meet the demand, which makes it especially difficult for the group outside the ordinary housing market. The need for housing must be met in a long-term perspective.  The aim of the thesis has been to investigate how planning is carried out for the group of housing applicants who are outside the ordinary housing market for various reasons, mainly due to limitations in the private economy and/or due to social aspects. To understand why there is a shortage of housing for this group, it has been examined how the state, regions and municipalities work. Case studies have examined the regional development plan for Stockholm with its visions and goals. The municipality's guidelines for housing supply have also been examined in 3 different municipalities in the Stockholm region, which have subsequently been analysed. Visions and goals in the regional development plan show that it must be planned and built for different groups in the housing market according to their needs. The municipalities have different tools for housing supply that are also used in several ways. In order for municipalities to have the conditions to succeed in housing supply, the regions should receive more support from the state to guide the municipalities in the right direction. This indicates that the supply of housing for the different groups can differ considerably. The extent of the housing shortage for this group is unclear. Previous research also shows that there are no methods for understanding the real housing need and statistics for the existing range. Due to the lack of tools, it is difficult to assess the need and how large this group is. Therefore, it is also difficult to know how much more resources and that more support to the municipalities is needed. It also confirms that there are deficiencies in the system of housing supply that should be addressed.
