Are there any legal restrictions on the designated use to which any new building may be put or on any change in the designated use of an existing building?
Yes, the Building Control Act B.E. 2522 and City Planning Act B.E. 2518 and its notifications are applicable. The Building Control Act B.E. 2522 controls the setback requirements of the building, and the City Planning Act B.E. 2518 controls the floor area ratio (FAR) (the ratio of a building's total floor area to the size of the piece of land upon which it is built) and the open-space ratio (OSR)(the proportion of a development required to be left as open space) and the designated use of the land.
