San Francisco property intelligence
Know the block
before it becomes
your block.
The Assessor's file on the building. Crime, permits, violations, parking, rents, transit, and what is approved to rise next door. Nineteen sections in about two seconds, as a PDF you can forward.
The corpus behind every report
What a report contains
Nineteen sections. Zero opinions.
Built to be believed
Every number is compared
A count on its own is unreadable. Nobody knows whether 21,521 incidents is a lot, so every figure is set against what an average area of the same size in San Francisco records, and expressed as a rate you can picture.
Nothing is scored
No safety grade, no risk number, no letter for the block. Those are opinions wearing a number's clothes, and on a page that can move a price that matters. You get the records and draw your own conclusion.
The caveats travel with the numbers
An assessment is not a valuation. A complaint is not a finding. Police locations are anonymised to the block. Each of those sits beside the figure it qualifies, in the report and in the PDF, not in a footer nobody reads.
The data, seams and all
Where the city changed how it records something, the report says so next to the number rather than in a footnote. Two examples: the two crime datasets overlap rather than abut, so the seam is explicit — and 311 renamed its entire taxonomy in June 2024, so a trend crossing that date says it compares two vocabularies.
