PROBLEM TO BE SOLVED: To provide a settlement correction method for building, capable of easily performing settlement correction of a building by effectively lifting up the foundation of a settled part of the building in a stable state by easy operation without needing labor hour. SOLUTION: The method comprises: the first step of forming a clearance 13a between the lower surface of a foundation 11 in the circumferential part of the building 10 of the settled part and a surface layer part 12a of a foundation ground 12, inserting and disposing an expansion steel pipe 18 to and in the clearance 13a, and expanding the pipe by force feed of water, thereby lifting up the foundation 11 in the circumferential part; and the second step of inserting and disposing an expansion bag body 20 to and in the inner part of the building 10 through a clearance 13b between the lower surface of the foundation 11 in the inner part of the building and the surface layer part 12a of the foundation ground 12, which is formed in the first step, and expanding the bag body by force feed of water, thereby lifting up the foundation 11 in the inner part of the building 10.
