What is Article 4 Direction?
A planning order by a local authority that removes specified permitted development rights, requiring owners to apply for full planning permission instead.
Full Definition
An Article 4 Direction is a tool used by local planning authorities in England (with equivalents elsewhere in the UK) to withdraw certain 'permitted development' rights within a defined area. Normally permitted development lets owners make some changes -- such as converting a home into a small house in multiple occupation, or changing a building's use -- without a full planning application. Where an Article 4 Direction is in force, those specific changes instead require planning permission, giving the council greater control. Authorities use them to protect the character of conservation areas, manage the spread of HMOs, or limit short-term holiday lets. For property investors and landlords this is significant: a planned conversion may suddenly need permission that can be refused, affecting purchase decisions, costs and rental strategy. Always check whether an Article 4 Direction applies before buying. It does not change tax such as Stamp Duty, but it can materially affect a property's value and intended use, so do due diligence with the local authority.
