B Can the office building be changed into a hotel?

I can't. The property right of Grade B office building is office and cannot be used for commercial purposes. Therefore, the property of office buildings cannot be changed to hotels. Grade B office building refers to a literal building with good geographical location, natural building conditions and building quality meeting the standards of relevant building regulations or codes, but its building function is not the most advanced, it has natural loss, its profitability is lower than that of similar newly completed buildings, and it has good property management services.
