This dissertation presents an archaeological study of household units and their surrounding built environment at the site of Chunchucmil in the northern Maya lowlands (Yucatan, Mexico). Complementary lines of evidence, the architectural, artifactual, and soil chemical spatial patterning are used at two residential groups of two different Classic Period occupations to elucidate changing patterns of domestic life. Chunchucmil grew to become a sprawling trading city in the middle of the Classic period (A.D. 400-650), while during the Late-Terminal Classic (A.D. 650-1000), after a dramatic depopulation, the site was home to only a few hundred people. This research focuses on the examination of domestic archaeological assemblages, use of space and formation processes in indoor and outdoor domestic areas, social and economic processes, and household dynamics operating in these residential groups during two dramatically different periods A site-level analysis with Geographic Information Systems (GIS) of the settlement layout, internal configuration of residential groups, and other features of the built environment for each period complements this study by elucidating the wider context for the transformations of the settlement and domestic life. By comparing residential groups and the layout of their contemporaneous settlement, I attempt to identify, at the domestic level, socioeconomic and political transformations occurring at the site throughout the Classic period (ca. 300/400-1000/1100 A.D.) The combination of extensive excavations inside buildings, grid testing across the extramural areas of houselots, study of archaeological assemblages considered in their depositional contexts, and geochemical sampling of floors and soils reveals a rich picture of domestic life at two Classic-period residential groups at Chunchucmil, the late Early Classic-early Late Classic Kaab' Group and the Late-Terminal Classic Xnokol Group. Traces of discard practices, ritual and everyday activities, patterns of use of space inside and outside structures, social and economic processes operating at the domestic level, and household dynamics are brought to light by the intersecting lines of evidence
