The strategy is designed to operate within this two-tier government framework. The city government has jurisdiction over most city-wide functions, including social housing funding and development, but it must work through the boroughs, which have control of local planning and development approval. The goal of the strategy is to provide housing for a mix of different income brackets in all new large housing developments. This is to be achieved particularly by facilitating the development of social housing, and stimulating the production of affordable housing for first-time homeowners.
