POLICE and firefighters were called to a landslip in Torquay yesterday morning.
Tons of earth appeared to have slipped at the property in Warren Road.
Police and fire crews were at the scene at 9am and residents were being evacuated for safety reasons.
Torbay Council's structural engineer was also at the scene.
Three private homes at the bottom of the hill were evacuated because they were in a "vulnerable position", while a fourth affected private property - on top of the hill - was empty, Torbay Council said.
A spokesman said: "There is still the possibility that more debris could come down and the council has been working closely with the building owners concerned, and a demolition contractor will start work this evening."
Affected residents were being moved to temporary accommodation.
