Parts of Central Accra comprise a mixture of very low-density development with under-used service infrastructure on the one hand, high-density development and overstretched infrastructure services on the other. The growth of Accra has led to the neglect of some of the old settlements, whilst efforts are being made to provide the newly developing suburban areas with services and infrastructure to cater for the needs of the middle-income earners. Peripheral residential development in Accra barely has sufficient infrastructure to support it. There are also large numbers of uncompleted houses, interspersed with pockets of undeveloped land, which are often subject of litigation, due to the inability of organisations and individuals who own them to complete or develop them due to lack of funds. Housing can be grouped into three broad categories: the low-income, middle-income and high-income areas. The low-income housing areas comprise Osu, Jamestown, Adedenkpo, Chorkor, La, Teshie, Nungua, Sukura, Kwashieman, Odorkor, Bubiashie, Abeka, Nima, Maamobi and Chorkor. Altogether, these areas accommodate about 58% of Accra's total population. Most of Accra's informal businesses are located in low-income areas.
