DataSF is the Office of the Chief Data Officer, and its open data portal lets you search by topic or browse by category, department, data type and tag.
The portal address is now data.sf.gov. Project SF uses the city’s neighborhood boundaries for its own events and listings.

The Portal Move
The portal notice says API queries or hardcoded links pointing to data.sfgov.org must be updated to use data.sf.gov by Nov. 20, 2026.
Analysis Neighborhoods
The city’s Analysis Neighborhoods dataset has 41 neighborhoods built from 2010 Census tracts. DataSF notes they are not statistical or official neighborhood boundaries. The dataset metadata states the Open Data Commons Public Domain Dedication and License 1.0. Project SF assigns events and listings to these neighborhoods by point-in-polygon on the city’s boundary data, not by name. See Neighborhoods.
Project SF Data
Our own datasets are on the data hub, with free downloads and a citation page for journalists at Data for Journalists.

What We Could Not Confirm
- The number of datasets on the portal.
- Exact download steps: they were not on the pages we read.
- The portal’s own page states no license; the one named is from the neighborhoods dataset.
