The Parcels data set from the City of Detroit Office of the Assessor is updated daily with land parcel data for all properties within the City of Detroit. Records in this data set describe the assessed values, rights, ownership interests, most recent sales data, physical descriptions, and addresses associated with each parcel. Parcels are distinguished from lots or plots of land in that property ownership rights are the fundamental units of division between parcels. The graphic depiction of land parcels represents real property ownership within the City for both privately and publicly owned properties.Data maintenance note: Databases used by the Office of the Assessor for parcels data are checked for updates daily. If an update is detected, the published Parcels dataset is then updated to reflect the most recent data available. Similarly, Zoning data provided by the Buildings, Safety Engineering, and Environmental Department (BSEED) Zoning Division is checked for updates daily. If any updates are available, values in the Zoning field are updated to reflect the most recent zoning data available. The "Data Updated" date for the Parcels dataset reflects the most recent date any data updates were detected and incorporated into the Parcels dataset. The GIS / Land Records Maintenance Division in the Office of the Assessor manages the data integrity of the parcel file.
