In 2021, Colchester City Council issued a Certificate of Lawfulness confirming the lawful use of a large outbuilding as an independent residential dwelling in the rural area of Colchester, Essex.
The outbuilding had originally been converted as a residential annexe, but had subsequently been let as a self-contained dwelling — inadvertently creating a separate residential unit. The case was resolved using the four-year rule, supported by statutory declarations, tenancy agreements and utility bills.
Certificate of Lawfulness for a Dwelling in Rural Colchester
A Certificate of Lawfulness of Existing Use was obtained from Colchester City Council for a large outbuilding in the rural area of Colchester that had been continuously occupied as an independent residential dwelling for a period well in excess of four years.
The building formed part of the residential curtilage of an existing property in a countryside location. The owners had originally converted it as a residential annexe for family use, but when it was no longer required for that purpose, they had begun to let it to private tenants — without appreciating that, in doing so, they had inadvertently created an independent dwelling that required separate planning permission.
The four-year rule under Section 171B(2) of the Town and Country Planning Act 1990 provides that no enforcement action may be taken in respect of a change of use of any building to use as a single dwellinghouse after the end of four years from the date the breach began.
Where that period has elapsed, the use is immune from enforcement and the Council must issue a Certificate of Lawfulness if the evidence meets the balance of probability standard.
The burden of proof rests entirely with the applicant. In this case, a comprehensive evidence package was assembled. This evidence was carefully organised into a clear timeline and submitted to Colchester City Council with a legal commentary explaining the applicable test and why the evidence satisfied it.
The Council accepted that the evidence demonstrated continuous independent residential occupation for well in excess of four years and issued the Certificate.
