HomeBase was a home improvement warehouse chain in the Western United States based in Irvine, California.

Robert J. McNulty and George Handgis founded the chain as a warehouse club called the HomeClub, opening the first two stores in Norwalk and Fountain Valley, California, in 1983.

After Zayre was acquired by Ames, HomeClub was spun off under a new company called Waban Inc., which also owned BJ's Wholesale Club.

Although it outperformed competitors like Orchard Supply Hardware and Builders Square, it could not match the growth or pricing power of The Home Depot or Lowe's.

On December 5, 2000, after several dramatically unprofitable years, it announced that 67 stores would be converted to a home decorating superstore chain, House2Home, and the remainder closed.
