The Derg administration (1974–1991)

After the Derg came to power, roughly two-third of housing stock transferred to rental housing. The population growth declined from 6.5% to 3.7%. In 1975, the Derg nationalized "extra" rental structures built by private stockholders. As a result, the Proclamationon No. 47/1975 issued weakened buildings with small amount of living was administered by kebele units, while rental houses with large quality fell under Agency for Rental Housing Administration (ARHA). If those rental properties value less than 100 birr (US$48.31), they would be put under kebele administration. The administrative divisions showed an increase of woredas to 25 and 284 kebeles.

Hungarian architect C.K. Polonyi was the first person to embark the city's master plan during the Derg period with assistance of the Ministry of Urban Development and Housing. He used two formula concentrating an integration Addis Ababa with suburbs of rural areas and developing inner-city. Polonyi also worked to redesign Meskel Square, which was renamed Abiyot Square by the time, implemented immediately after the name change.

In 1986, the Italo-Ethiopian master plan was set up by 45 Ethiopian professional along with 75 Italian experts with 207 sectorial reports documented as references. The plan dealt with a balanced urban system and services in urban area such as water supply. Akaki incorporated to Addis Ababa to supply industrial and freight terminal services. The bureaucratic rule of the Derg postponed the master plan for eight years until 1994, which caused failure of basic issues in public service and unplanned development.
