Building construction in Indonesia must adhere to technical requirements as imposed by the government. Government Regulation No 36 of 2005 regarding the Implementation of Law No. 28 of 2002 regarding Building (GR 36/2005) imposes an "intensity requirement" for the construction of a building, whereby a building must be constructed not exceeding certain maximum density and height limits that are stipulated by the relevant regional government.
In the calculation of the maximum density and height limits, the following are terms commonly used, as well as the respective statutory definitions, which can be found in
Minister of Public Works and Housing Regulation No. 06/PRT/M/2007 of 2007 regarding General Guidelines for Building and Neighborhood Spatial Layout (MPW Reg 06/2007):
