A community interest development is a property or regeneration project designed and operated primarily for community benefit rather than private profit. In UK and Irish legal practice, the term is descriptive rather than a defined statutory concept, and may encompass housing schemes, mixed‑use developments, community land trusts, social enterprises, and assets of community value.Such developments commonly involve legal structures that lock in social purpose, for example community interest companies (CICs) in the UK, charities, co‑operatives, or community benefit societies, and may rely on planning obligations (section 106 agreements in England and Wales), community right‑to‑buy mechanisms, long leases, or restrictive covenants to secure ongoing community use.In England and Wales, Scotland and Northern Ireland, the phrase is often used in planning law, housing, public procurement, and regeneration projects, but without a uniform statutory definition. In Ireland, it is likewise used in policy, social housing and community-led development contexts rather than as a term of art.Practitioners typically address community interest developments when structuring land ownership, drafting governance documents, securing funding, or negotiating with local authorities and public bodies to ensure long‑term community benefit and compliance with regulatory and charity law requirements.
