Planning enforcement is the process through which a local planning authority investigates and responds where it believes there may have been a breach of planning control. This can include unauthorised building works, a change of use or failure to comply with a planning condition.
Depending on the case, the authority may seek information, request corrective action, invite an application or serve a formal enforcement notice. A formal notice can require works to be removed, a use to cease or another specified remedy to be completed within a set period.
