Do hotel offices and ordinary offices mean the same thing?

No.

Ordinary offices are located in the business building. Commercial building refers to the general name of office buildings and office buildings with less than seven floors used for commercial services. A building with more than eight floors can be called a building. Commercial and residential buildings refer to comprehensive buildings in which the ground floor (or several floors) are shopping malls, shops, and businesses, and the rest are residential buildings. Commercial-office complex buildings and commercial-residential complex buildings are both listed as one of the 42 construction project names within the construction land suitable range by Shanghai Municipal Planning and Management Technical Regulations.
