In County of Los Angeles v. Hartford Acc. & Indem. Co. (1970) 3 Cal. App. 3d 809, the developer sought to convert an apartment building into condominiums. The attempt failed, and the county sought to recover on a bond given as a condition to the recording of a final tract map. In discussing the purposes for which the bond was given, the court noted that, 9 under the Civil Code definition of "condominium" (formerly Civ. Code, 783, now contained in 783 & 1351, subd. (f)), "there can be no undivided interest in common (and thus by statutory definition there can be no condominium) until at least one condominium unit has been conveyed by the subdivider." (County of Los Angeles, at p. 814.)
