The National League South club hope to be back at Treyew Road for their FA Trophy tie with Weston-super-Mare on December 15.
The White Tigers have been sharing with Torquay United this season but that agreement is set to be cut short before Christmas with their old ground nearly ready for football again.
A Truro statement read: “We are delighted to announce that we have been given permission to play our Buildbase FA Trophy first round tie against Weston super Mare at Treyew Road on Saturday, December 15th, subject to obtaining the ground grading by no later than 5.00pm on Thursday 13th December.
“Given that the schedule of repairs has been completed, obtaining the ground grading should now be a formality.
“We look forward welcoming all supporters back to Treyew Road and joining us in the Clubhouse after the game where there will be a players' presentation.
“This news marks yet another important milestone in history of the club.”
