Strategic Development Costs (SDC) are additional costs associated with the development of housing in the UK, which are intended to promote economic growth and improve the quality of life for local communities. These costs are paid to local authorities or other public bodies to fund the provision of infrastructure, educational, recreational and other improvements which are necessary for a successful housing development. SDCs cover a wide range of projects such as road and public transport improvements, environmental protection and community facilities. These projects are usually funded by developers or other private sector organisations, and are designed to facilitate the delivery of housing and other development projects in a timely and cost-effective manner. SDCs are intended to encourage the development of more sustainable and affordable housing, while also stimulating economic growth in the local area.
