Up to eight stations across Devon and Somerset could close as the shared fire service looks to save £8.4 million.
Appledore, Ashburton, Budleigh Salterton, Colyton, Kingston, Porlock, Topsham and Woolacombe are set to shut.
Six restructuring options will now be presented to the fire authority, all include shutting stations and the removal of fire engines.
These would be the most significant changes made to the service in half a century.
The service has already saved £12.2 million over the last five years but needs to save a further £8.4 million over the next three years.
Managers say they have carefully reviewed where staff and appliances are needed to minimise risk.
Devon and Somerset Fire currently have 85 stations, 121 fire engines, and 2,000 members of staff making them the biggest non-metropolitan fire and rescue service in the country.
The number of fires in the force area reduced by more than a third over the last decade.
The service says they want to bring the emergency service into the 21st century.
A 12 week consultation is expected to run from 1 July to 20 September 2019.
