Active Parcels (from DataSF, pulled daily)

Recorded parcel geography, only showing active parcels, with date recorded parcel was added, date recorded parcel was dropped/retired, date was added, dropped or altered re map layer. Contains geography created since the inception of the basemap in 1995, with some exceptions. Zoning District columns reflect current zoning. This data has been filtered to only include active parcels. Data pushed to ArcGIS Online on July 4, 2026 at 5:19 AM by SFGIS. Data from: https://data.sfgov.org/d/acdm-wktn Description of dataset columns: mapblklot For parcels that are condominium lots and share the same 2D space, this is the lowest value Assessor Parcel Number in the set. blklot Unique Assessor Parcel Number, combination of the Block Number and the Lot Number block_num Assessor Block Number lot_num Assessor Lot Number from_address_num From Address Number, i.e., the lowest address house number to_address_num To Address Number, i.e., the highest address house number street_name Street Name street_type Street Type, or suffix (e.g., ST, BLVD, etc.) odd_even Odd or Even Address Number Range in_asr_secured_roll Indicates the record is in the current Assessor Secured Roll pw_recorded_map Indicates the record is part of the current Public Works basemap dataset, based on recorded map information. zoning_code Zoning Code - based on City Planning data zoning_district Zoning District Name - based on City Planning data date_rec_add This is the date that the documents related the to addition of the parcel was recorded, as tracked by Public Works. date_rec_drop This is the date that the documents related the to dropping/retiring of the parcel was recorded, as tracked by Public Works. date_map_add This is the date that Public Works adding the parcel geography. date_map_drop This is the date that Public Works dropped the parcel geography. date_map_alt This is the date that Public Works altered the parcel geography. project_id_add This is the project identifier for the Public Works project related to the addition of the parcel. project_id_drop This is the project identifier for the Public Works project related to the dropping/retiring of the parcel. project_id_alt This is the project identifier for the Public Works project related to the altering of the parcel. active shape The geometry, multipolygon format centroid_latitude The centroid latitude of the parcel centroid_longitude The centroid longitude of the parcel supdist Full name of Supervisorial District. supervisor_district Supervisor District Number supdistpad Supervisor District Number with zero padding (01,02,...) numbertext Supervisor District Number as text (ONE, TWO, ...) supname Name of current Supervisor of District. analysis_neighborhood San Francisco Neighborhood for analysis, per DataSF. police_district The corresponding SFPD district. police_company The corresponding SFPD district company. planning_district These are grouping of census tracts.
