Tanzania's 14.3 million buildings expose the scale of its Vision 2050 housing challenge
Written on
The Tanzania Building Census 2022 counted 14,348,372 buildings, overwhelmingly low-rise, privately owned homes, highlighting the built-environment gap the country must close to reach its Vision 2050 goals.
Tanzania counted 14,348,372 buildings in its 2022 Building Census, with 13,907,951 on the Mainland and 440,421 in Zanzibar, according to an analysis published by Uchumi360. Rural areas accounted for 10,038,201 buildings against 4,310,171 in urban areas, while Dar es Salaam had the most buildings on the Mainland at 913,707, followed by Mwanza at 868,430 and Dodoma at 836,909.
The census shows a built environment still dominated by housing rather than production. Some 91.4 per cent of buildings are used for residential purposes, 3.4 per cent for both residential and commercial use and only 5.2 per cent for non-residential purposes such as commerce, institutions, industry and worship.
Density is also low. About 94.4 per cent of buildings are not storey buildings and only 0.5 per cent are storey buildings; Zanzibar records 1.7 per cent storey buildings while Dar es Salaam leads the Mainland at 3.5 per cent, followed by Arusha at 1.3 per cent. The census warns that the dominance of single-storey buildings signals urban sprawl that can weaken the efficient provision of roads, water, electricity and other services.
Service and tenure gaps are wide. Only 22.8 per cent of buildings are connected to grid electricity supplied by TANESCO or ZECO, while 67.1 per cent were built on land that had not been planned or surveyed and 33.3 per cent on land without legal ownership documents, a direct constraint on formal finance and investment.
Ownership is overwhelmingly private, with 87 per cent of buildings owned by individuals, 9.8 per cent under joint ownership and 3.2 per cent by government or institutions. The data also exposes a gender gap: 71.5 per cent of individually owned buildings are owned by men, compared with 23.4 per cent owned by women and 5.0 per cent under joint ownership.
The census points to a large retrofit and rental market. About 51.3 per cent of assessed buildings need repair, including 12.8 per cent requiring major work, and 1,902,724 buildings were recorded as unused, mostly because construction was still ongoing. With 98.2 per cent of residential and residential-commercial buildings holding only one unit, the analysis argues Tanzania's path to Vision 2050 depends on formalising land, encouraging denser multi-unit housing and expanding productive real estate.
