West Lindsey DC has again told the Home Office to cease work at RAF Scampton.
On Friday, officers served an enforcement notice and a stop notice in relation to development of the site, which is due to house 2,000 asylum seekers.
West Lindsey had issued a temporary stop notice earlier this month after considering there to have been a breach of planning control relating to the listed buildings and archaeology on the site.
The council said it was 'clear' during a later site visit that planning control had been breached.
Council leader Trevor Young said: ‘It is incredibly disappointing that, despite repeated assurances that the site would be safe, legal and compliant, the Home Office has failed to secure appropriate planning permission or to adequately assess the impact of their proposals.
‘It is an offence to contravene the stop notice and I urge the Home Office to cease all works in line with this legal action.’
A Home Office spokesperson said: ‘Delivering accommodation on surplus military sites provides cheaper and more orderly, suitable accommodation for those arriving in small boats while helping to reduce the use of hotels.
‘We are confident our project, which will house asylum seekers in basic, safe and secure accommodation, meets the planning requirements.’
