Google's Open Buildings is an open access dataset containing the geometry of buildings across most of Africa, South Asia and South-East Asia. This version of the dataset is transformed to be partitioned by admin 1 boundaries and available in cloud-native geospatial formats (PMTiles, GeoParquet). Note that https://source.coop/repositories/vida/google-microsoft-osm-open-buildings/description is likely a better source for this data.
There is no commitment to keep this dataset up to date with the latest releases. The code used to do the processing can be found at https://github.com/opengeos/open-buildings
