Based on a survey, this paper presents new data on the decentralisation of the housing system and co-ordination mechanisms across levels of government, focusing on the provision of social housing. Decision-making in social housing tends to be more devolved to sub-national actors, as compared to other key public services. Policy decision making tends to be more centralised, while sub-national governments and housing providers have more control over decisions regarding the inputs, outputs and monitoring of social housing. Governments globally have implemented a mix of housing policy interventions. Demand side interventions include tax allowances and subsidies to facilitate the purchase of a home or the provision of social housing in the rental market to those in need. Interventions to influence the supply of housing are generally aimed at housing developers or sub-national governments, to stimulate housing construction. There are a number of policy tools readily available to sub-national governments to improve housing outcomes, including the implementation and reform of taxes on immovable property and the relaxation of restrictive land use regulations.
