San Francisco Parcels with Administrative District Overlays

A daily-updated composite dataset from DataSF pre-joins active and retired land parcels with four key administrative boundaries. This dataset is designed to simplify matching parcels to non-overlapping districts without requiring spatial processing for each analysis. It is maintained by the City of San Francisco and was last updated on March 22, 2026.

Use Cases

• Assigning parcels to analysis neighborhoods for demographic or economic studies.
• Joining parcel data to supervisor districts for political or policy analysis.
• Matching properties to police districts for public safety or resource allocation modeling.
• Linking land parcels to planning districts for zoning or development review.

Strengths

• Updated daily via an automated script, ensuring alignment with the source parcels dataset.
• Pre-processed spatial overlays for four distinct administrative boundaries, simplifying joins.
• Boundaries are non-overlapping, guaranteeing each parcel is contained within a single district.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
