In an attempt to control the rapid growth of the city, the municipal government (Municipalidad de Guatemala) headed by longtime Mayor Álvaro Arzú, has implemented a plan to focus growth along important arterial roads and apply Transit-oriented development (TOD) characteristics. This plan denominated POT (Plan de Ordenamiento Territorial) aims to allow taller building structures of mixed uses to be built next to large arterial roads and gradually decline in height and density moving away from such. It is also worth mentioning, that due to the airport being in the south of the city, height limits based on aeronautical considerations have been applied to the construction code. This limits the maximum height for a building, at  in Zone 10, up to  in Zone 1.
