Hong Kong authorities have approved the city’s first three subdivided units to comply with official minimum standards, with the successful applicant urging landlords to seek professional help to avoid wasting time and money. Hayson Chan Hin-hay said the Housing Bureau had approved his three subdivided units in a flat in Sham Shui Po as “basic housing units” last week. Chan, chairman of the Hong Kong Basic Housing Units Operators Association, said he filed the application in late May.
