All new apartment buildings in Athens will be required to have a parking space for each unit of at least 100 meters in size, according to a presidential decree drafted by the Environment and Public Works Ministry. The decree also rules that construction companies will no longer be able to buy parking spaces in a building in order to convert them for other use. Generally, the decree’s provisions constitute an attempt to restrict city congestion. For example, all cinemas, supermarkets, shopping malls and even banks or schools will have to provide sufficient parking spaces to accommodate visitors, customers and staff. According to the current law on apartment block parking spaces, builders in northern suburbs such as Maroussi are required to provide a parking space for every 100 square meters of apartment space, whereas in Keratsini, near Piraeus, the requirement is only for every 200 square meters. The new law provides for one parking space for every 100 square meters of units throughout Attica.
