Can gta online apartments be accessed in story mode?

Grand Theft Auto Online is a separate game mode from the single-player story mode of GTA V. Online allows players to create custom characters and engage in multiplayer activities, including purchasing customizable apartments and other properties. These properties are tied to the Online experience and require playing in the online multiplayer environment. The story mode, which follows the narratives of Michael, Trevor, and Franklin, has its own distinct set of properties and mechanics that are unrelated to Online's apartment system. Accessing Online-specific features like apartments requires being in the online mode, as the two modes operate independently with separate save data and game mechanics.
