PROBLEM TO BE SOLVED: To solve the inconvenience of a conventional method for setting a base isolation device to an existing building, in which a temporary jack must be set in a position distant from a column. SOLUTION: The method for setting a base isolation device 10 to an existing building 15 includes: winding a reinforcing metal plate 2 around the whole circumference of the side wall surface of an existing column through a required gap (a); injecting an adhesive material to the gap (a) followed by hardening; fixing a temporary support pole 4 to the reinforcing metal plate 2; setting a lifting device 5 between the lower part of the temporary support pole 4 and a foundation; causing the lifting device to bear the axial force of the existing column 1 through the temporary support pole 4 and the reinforcing metal plate 2; cutting the lower part of the existing column 1 to mount the base isolation device 10; and thereafter causing the base isolation device 10 to bear the axial force of the existing pole 1 by the lifting device 5 to remove the lifting device 5 and the temporary support pole 4.
