The View | Disastrous rent control laws and building codes in Hong Kong

In 1969, my classmate’s family moved into the Man Cheong Building in the Jordan area. If you drive by the area, you can still see it – it is part of the “saw-tooth” skyline of four buildings facing the western reclamation site.
A 1979 study by Professor Steven Cheung on rent control and housing reconstruction in Hong Kong touched on the fascinating economic story behind these buildings and my essay here draws heavily on his work.
These buildings reflect the disastrous historical effects of rent control legislation and building codes on development.
The problem started in 19th century London, where one of the controlling factors for regulating the height of buildings was the light-angle. This was motivated by a concern that the lack of sunlight at street level contributed to unsanitary conditions.
The English Public Health Act of 1875 regulated the situation by aiming for a maximum diagonal of 45 degrees between the building line (at ground level) on one side of a new street and the skyline formed by eaves on the other side.
