Following my last blog I did a little more research and discovered that an unauthorised change of use to a single dwelling is immune from enforcement by a local planning authority after 4 years and not 10. Any legal or planning experts care to comment on this?
This results from case law which you can read about here.
Not sure if this will always apply, but if it does it could be significant for anyone hoping to get a certificate of lawful use from their local authority. If the Localism Bill does indeed remove the immunity given by the 4 and 10 year rules, the window of opportunity for those occupying a barn, warehouse, shop, or dwelling with occupancy restriction etc. or who have converted part of their own home such as an adjoining barn without consent, may be closing.
