People living in Calstock are concerned over the safety of their homes after a section of road collapsed following heavy rain.
More than 20 properties in the village are without road access after the landslip on Lower Kelly on Christmas Day.
One of the properties has developed "fine cracks" following the collapse, residents have said.
Resident Lyn Edwards said: “Clearly as residents we have some concern about our safety.
“I can't sleep in my bed at night at the moment. We have requested Cornwall Council to conduct a full structural survey on five properties to reassure us as it seems the slippage is getting closer and closer to our front walls.
She added five properties were immediately behind the landslip and residents were “very, very nervous.’’
Resident Nigel Rushbrook said: "The worst case is our houses will go, the houses above will go and the road above that.’’
“We are sleeping slightly fitfully... there are noises in the night which we think, 'is that the house?
“We have all important stuff and bags packed just in cases.’’
Dorothy Kirk, Cornwall councillor for Gunnislake and Calstock, said a structural engineer assessed the stability of the terrain" on Boxing Day and assessed the safety of the houses and allowed the residents back in.
Mrs Kirk said: “Cornwall Council are willing to pay for hire cars so people who can't get their cars out can get to work and get around.
"Emergency services have reassured us they have means of delivering supplies."
Ms Kirk added that highway engineers would be reassessing the road on Monday.
