Guides

How to read a property record, where San Francisco's own rules decide the answer, and what the records will not tell you. Written for whoever is holding the document — a buyer, a renter, an owner, an agent, an investor or developer, an underwriter placing cover or credit, or the board of an association that has just inherited somebody else's deferred maintenance.

12 guides for agents and brokerages, including the ones written for everybody. Show all 20.

For anyone holding a report

How to read a report

Forty-two sections in the order they matter, what each comparison actually claims, and the three places the report is deliberately silent.

For buyers, owners and agents

Permits, and the work nobody filed

How to read a parcel's permit history, what an open permit costs the next owner, and why the useful signal is often what the record does not contain.

For anyone holding a report

What this report will not tell you

The refusals are deliberate and worth knowing: no score, no person, no valuation — and the gaps in the records themselves.

about 3 minutes · Aug 2026
For agents

Working with clients

The questions a client actually asks, the record that answers each, and the sentence to use instead of the one that creates a Fair Housing problem.

For anyone in San Francisco

Earthquakes, ground and hazard zones

Six different things people call “seismic risk”, what each one actually is in San Francisco, and the one this report cannot tell you.

For everyone

Who to actually call in San Francisco

This report is a record. These are the people who decide — the Rent Board, DBI, the Assessor, and the organizations that help for free.

Reference

The words San Francisco uses

3R, Costa-Hawkins, Maher, blklot, CFC, Tier 4. A reference for the terms that turn up in a report and nowhere else.

For a brokerage desk

Running a desk on public records

How a San Francisco brokerage desk uses one report to answer the questions that otherwise cost a week — and where the city's own rules decide the answer.

about 7 minutes · Aug 2026
For a brokerage

Property records at brokerage scale

Fifty seats, a hundred reports a day, and two machine surfaces. What to automate, what to leave to a person, and how to keep the record defensible.

about 4 minutes · Aug 2026
For lenders and underwriters

Lending against a San Francisco building

The obligations that transfer with a parcel, the ones with a deadline attached, and why San Francisco publishes no lien, default or foreclosure record at all — which changes what due diligence has to cover.

about 3 minutes · Aug 2026
For developers and builders

Getting a project through in San Francisco

What the parcel allows, what is already approved on the block, and the sequence of public filings a project leaves behind — read as a schedule rather than as a list.

about 3 minutes · Aug 2026
For anyone watching the record daily

What San Francisco files every day

The kinds of filing San Francisco publishes against its buildings and storefronts, how far behind each one runs, and why a list built on the filing date misses most of what was filed.

Then read the record on an actual address

One San Francisco address, one report: the Assessor's file, permits and violations, zoning, hazards and the published earthquake maps, rent control, and ten years of the surrounding blocks — every count compared with the city, and none of it scored.
