The Association has lobbied successive governments for nearly a decade to allow the use of barns and other agricultural outbuildings to be changed under permitted development rights. Ministers have now announced these proposals will come into force on 30 May.
CLA President Harry Cotterell said: "Allowing farm buildings of 500m2 or less the flexibility to change into a range of new business uses will help to stimulate rural economic growth.
"It will help underpin farming businesses currently under pressure by creating new jobs and businesses at a time when they are greatly needed in the countryside."
He added: "We are also pleased to see new regulations allowing the change of use of offices to residential. Many CLA members are currently paying empty property rates because of a lack of business tenants so allowing a change of use will reduce costs and provide much-needed homes in rural areas."
