This article compares domestic subsistence, craft production, and ritual at several excavated apartment compounds in Teotihuacan, Mexico. A new methodological approach for studying activity areas was tested in a multifamily compound at Oztoyahualco 15B:N6W3 with the purpose of obtaining information on specific activities attributable to particular households. This approach combines the identification and mapping of chemical compounds in stucco floors with pollen, phytolith, botanical, and faunal analyses. Together with the distribution of particular types of artifacts, ritual objects, and debris, these data permit an evaluation of the corporate character of certain activities.
