Do you have a particular period in mind? All three cities have long occupation histories, and daily life in Mesopotamia changed over time.

General introductions: Daily Life in Ancient Mesopotamia by Karen Nemet-Nejat and Everyday Life in Ancient Mesopotamia by Jean Bottero are excellent general introductions. Stephen Bertman's Handbook to Life in Ancient Mesopotamia is also fairly good.

Saggs' The Greatness that was Babylon and The Might that was Assyria are dated but still very useful. You should also take a look at Early Mesopotamia: Society and Economy at the Dawn of History by J. Nicholas Postgate.

Detailed essays: Sumer and the Sumerians by Harriet Crawford, The Sumerian World edited by Harriet Crawford, The Babylonian World, and A Companion to Assyria edited by Eckart Frahm contain several chapters each on daily life in Mesopotamia. All are quite expensive, though.

OB Period: We are arguably best informed about the Old Babylonian and Neo-Assyrian periods, both of which have extensive documentation. For life in Old Babylonian Syria and Mesopotamia, see Mari and Karana: Two Old Babylonian Cities by Stephanie Dalley and Hammurabi of Babylon by Dominique Charpin. Jack Sasson collected a variety of Old Babylonian letters in From the Mari Archives: An Anthology of Old Babylonian Letters that shed light on life in one of the major Syro-Mesopotamian cities.

Mesopotamian cities: For information on the cities themselves, see The Ancient Mesopotamian City by Marc Van de Mieroop, Mesopotamia: The Invention of the City by Gwendolyn Leick, and Royal Cities of the Biblical World edited by Joan Westenholz.

Several books and exhibition catalogues have been published on each city, including Uruk: First City of the Ancient World edited by Nicola Crüsemann, et al., Babylon by Joan Oates, and Nineveh, the Great City: Symbol of Beauty and Power edited by Lucas Petit and Daniele Morandi Bonacossi.
