The Buildings Department has proposed new guidelines on floor numbering and revised a practice note which details the numbering system.

     It is recognized the omission of floor numbers "4", "13" and those ending with a "4" has been adopted widely in buildings in Hong Kong.

     To strike a balance, it is proposed the omission of 4, 13 and those ending with a 4 may be accepted. Except for this type of acceptable omission, assigning floor numbers with other omissions will not be allowed.
     Under the new guidelines, the use of non-numerical names (unless indicated together with the normal floor numbers, e.g. 20/F Sky Garden), alias names, alternative floor numbers (e.g. in the form of "also known as X/F"), illogical or non-consecutive numbers, will not be accepted for assigning floor numbers.

     The department will apply the new guidelines on floor numbering to new development projects where an application for occupation permit was submitted on or after September 1.
